Extraído do website phoenixcs:

"the Revelation II Board Chess development is at the final stage, getting ready for production. We will demonstrate the first production model on the International Toy Fair 2012 at Nuremberg at the DGT stand to the specialist trade. And i will be attending on the first two days, working together with the DGT team, to demonstrate the Revelation II Chess Board. You are encouraged to join us for a demonstration, and if you want to get the demonstration from my hand, i will be there the first two days (1st and 2nd of Februar 2012). I am happy to demonstrate the system to you. On the other days a small demonstration is also possible, however an indeep demonstration can only be arranged on the first two days"

Como as brancas conseguem sobreviver ante a seguinte posição? (problema extraído do blog de Judit Polgar)

2012-01-25T20:27:00.001-02:00

Como se comportaram as máquinas ante esta posição?

Modulo Maestro 6 MHz

2012-01-24T21:19:00.000-02:00

Considerei em postagem anterior, que as informações sobre o módulo Analyst D++ são restritas e não consigo reunir dados que este modulo possa ter sido disponibilizado em série pelo fabricante SciSys, hoje Saitek. Nesta postagem, indico as características do módulo Modulo Maestro na versão 6MHz. Nota-se que o processador tem barramento de 4MHz, e o seu layout idêntico à versão com clock de 4MHz, o que me faz crer a princípio, que mudando a eprom da versão de 4MHz e alterando o clock de 4 para 6 MHz, teríamos o módulo atualizado para 6MHz. Por absoluta falta de tempo, não conferi se os componentes que compõe a memória do módulo 4MHz, tem as mesmas características da versão em 6MHz. Notar que a eprom de 6MHz tem a versão A29B ao passo que a versão de 4MHz, tem grafado o número V148.

Para uma análise mais acurada, a seguir o layout com os componentes do modulo em 4MHz:

Elite Avant Garde em duas horas, não conseguiu ganhar

2012-01-22T23:08:00.000-02:00

Testando o Elite Avant Garde, 2 horas contra 1 minuto para as engines Alex/Fritz 13, chega-se aquela velha máxima: as fraquezas apresentadas pelas máquinas dedicadas era a completa ausência de conhecimento de final de jogo. Lógico que o teste em si não faz muito sentido, pois 60 segundos para um computador com 6 cores, mesmo com engine que não suportaria mais do que um core, é uma maldade, haja vista o processador do Elite, um Motorola série 68000 rodando a 20 MHz. Mas no mínimo, foi divertido, pois percebe-se que as máquinas do passado tinham suas qualidades. No Elite, não obstante não ter lido matérias a respeito, seus programadores deram preferência em valorar o Bispo com peso acima do Cavalo, pois sempre que possível, Elite prefere manter seus Bispos.

Produtos de qualidade duvidosa

2012-01-22T21:57:00.001-02:00

O artigo publicado no Estadão, traz a baila um tema que merece reflexão. Seguramente, estariam fora deste postulado, os produtos fabricados pela Novag, Mephisto, Fidelity e antiga Saitek, década 80/90. Mas como conciliar as implementações tecnológicas com o lixo eletrônico, o qual apresenta-se a cada dia, mais frequente em nossos meios.

Em síntese diz o artigo:

"A obsolescência programada reduz a durabilidade de produtos para estimular o consumo, mas um documentário vem mostrar o lado sombrio desta prática raramente admitida pela indústria"

“A obsolescência programada sempre faz sentido enquanto você pensa em como manter o crescimento da indústria e a criação de empregos a curto prazo”, diz Cosima. “O problema é a longo prazo. Estamos usando nossos recursos naturais e criando montanhas de lixo. A obsolescência programada funcionou bem no passado, mas estamos começando a ver as consequências. É um sistema que não pode ser usado para sempre.”

Modulo Maestro - Maestro SciSys modelo 515

2012-01-19T12:55:00.000-02:00

Módulo construído para rodar em 4, 6 e 10 MHz. Informações sobre o módulo D++ são restritas e não vislumbro literatura que este modulo possa ter sido construído pelo fabricante. O módulo a seguir figura na versão de 4MHz e por isso seu fraco desempenho. Quem sabe posso arriscar e trocar o processador para 6MHz com clock de 10 MHz, vale a pena tentar.

Resistores, por Engº Alexandre Anderman Pipano

2012-01-17T17:57:00.005-02:00

Tendo em vista que a matéria interessa a nós colecionadores, pois via de regra estamos procedendo manutenção nos computadores de xadrez, segue uma explicação sintetizada pelo Engº Alexandre Anderman Pipano.

Resistor, como o nome diz, oferece resistência, então pode ser utilizadoem diversos circuitos para diminuir tensão, para filtrar, para isolar, etc...

Na maioria dos casos, os resistores são lidos considerando as trêsprimeiras listas, sendo que a primeira e a segunda indicam um nº cada, e a 3ªindica a quantidade de zeros. Os valores das cores das listas são:

0 - preto; 1 - marrom; 2 - vermelho; 3 - laranja; 4 - amarelo; 5 -verde; 6 - azul; 7 - roxo; 8 - Cinza e 9 cor branca.

Exemplos:

marrom, preto, vermelho = 1.000 ohms

amarelo, roxo, laranja = 47.000 ohms = 47k

verde, azul, amarelo = 560.000 ohms = 560k

azul, cinza, preto - 68 ohms = 68R

laranja, branco, dourado = 3,9 ohms = 3R9

Livro de aberturas - Parte 2, contemplando Super Expert C

2012-01-08T22:55:00.000-02:00

Super Expert C, por Novag, chegou ao mercado em 1989. Versões anteriores, "A" em 1987 e "B" em 1988. A versão "B", taticamente mais forte, entretanto não reconhecia alguns conceitos posicionais, é o que dizem os colecionadores. Livro de aberturas por Larry Kaufman, que também foi o co-autor do programa Rexchess.

Siciliana no Elite A/S

2012-01-05T00:32:00.000-02:00

Elite A/S foi desenvolvido pela Fidelity Electronics em 1982/1983, com algumas versões, tais como Budapest e Glasgow, apenas para resumir. Existem registros de outros desenvolvimentos de fábrica rodando em 8MHz, mas não tenho dados concretos sobre estas versões. Os originais contemplavam 3,2 MHz e 4 MHz.

Entretanto, o objetivo desta postagem foi verificar a extensão do livro de aberturas, inserido no Elite A/S, notadamente quanto a defesa siciliana, tendo em vista que a estatística mostra que contra e4, c5 é o movimento que mais sucesso consegue contra o lance inicial das brancas. O fato é que de lá para cá, não vislumbrei novidades importantes quanto aos movimentos iniciais, o que demonstra a qualidade do livro de abertura da série Elite.

Torneio Xadrez - 30 minutos

2011-12-11T10:49:00.001-02:00

De 2002 a 2006, participei ativamente nos torneios promovidos pela chessbase na sala demáquinas. Igualmente, em quase todos freestyle, torneio entre humanos, no qual poderia ter a interferência da máquina. Apenas para lembrar, Nakamura jogou em um desses torneios, mas não se classificou. Cheguei ao "top" do overclock noscomputadores que tive. Tempos com AMD, tempos com processador Intel. Tive dual,quadricore. Embora com os quadricores dominando na época, diversas vezes acompanhei partidas de single core ganhando de dualou quadricore. A opinião generalizada da pequena comunidade de máquinas era eainda consiste: O livro de aberturas corresponde a 60% da performance damáquina ou do humano, meio de jogo e final é consequência daquilo que se constroi, evidente, guardadas as devidas proporções quando se trata de jogos entre humanos. E não é por acaso, pois veja o depoimento de Nakamura:

Nakamura :

"Daniel King – Tell us a little moreabout working with Garry Kasparov. You enjoy those sessions?

Hikaru Nakamura – There is something to be gained. Mainly it’s the opening preparation he did with his team over thepast 20-25 years of his chess career. That’s really the strength of workingwith someone like Kasparov. It’s his opening preparation because a lot of hiswins came just out of getting good positions out of openings as a player. Soit’s mainly looking at openings and working from there. There are other thingslike studies and endgames, but it’s pretty much the openings." (g/n)

Certa vez, vendo um jogo do Milos no clube de xadrez, fiquei intrigado, visto que demorou mais do que o normal para fazer o 3º lance. Ele pensou muito. Isto é, ou ele já sabia o que deveria jogar, mas pensava nas consequencias, talvez desejando lembrar de partidas com aquela linha especifica, ou estaria em dúvida sobre o que jogar. Pessoalmente, fico com a primeira opção. Por outro vértice, há quem diga que não se pode perder esse tempo na abertura, porque não restaria sobras no decorrer do jogo.

Neste tema, sobre o pequeno torneio que realizei este mês, este fato ficou mais uma vez provado, pois dependendo da linha em determinada abertura, mesmo os jogadores mais fortes ficam com sérios problemas.

Ainda, talvez a partida entre MMIV e Analyst, tenha sido a melhor do torneio. O diagrama ao lado mostra o MMIV com as brancas em ataque fantastico, entretanto em jogo seguinte, perde em poucos lances do Elite 2100.

Universal Chess Board
fabricado pela Novag. Seria repetitivo descrever suas características, pois muita tinta já se gastou acerca deste modelo. Uma breve busca no google, teremos resultados significativos, inobstante que o melhor sitio de pesquisa seria em:

Universal Chess Board

Fabricado em 1996, tinha como objetivo fazer companhia para alguns programas que rodavam nos sistemas predecessores do Windows 7 e Vista, além do Sapphire, vide em computer info da própria Novag. Os programas de xadrez já testados consistem:

• Fritz 1, 2, 3, 5.16, 5.32, 6
• Hiarcs 6, 7.32
• Genius 3
• Mephisto Advantage
• Rebel 7, 8, 10
• WChess
• Winboard 4.2.7
• WinboardX
• Arena mit speziellem Treiber

Posteriormente, ante o desenvolvimento de programas como o CEboard, vide

CEboard

o Universal Chess Board, acabou-se por se constituir em um mini DGT, com dimensões menores e com limitações, já que não possui o sistema de reconhecimento de peças, conexão com os programas atuais, tais como Fritz 13 e outros distribuídos pela Chessbase. Em resumo, com um Ipaq rodando @ 400 MHz, utilizando o CEboard em conjunto com o Universal Chess Board, ainda, com engines instaladas, toga, fruit, gambitfruit, pode-se esperar um desempenho de 2300 a 2400 de rating. Observa-se que quanto maior o tempo, melhores chances tem o humano, em blitz, torna-se complicado ganhar.

Xadrez, uma aptidão.

2011-11-29T10:02:00.001-02:00

Tenho repetido que entender asparticularidades do xadrez não é questão apenas para superdotados, destinados aqueles que possuim capacidade mental significativamente acima da média, comoalguns dizem e sim ter aptidão. Alguns possuem aptidão para determinada atividade, outros seguem caminhos diferentes, como a música por exemplo. Digo isso, porque se elegermos 10 enxadristascom rating superior a 2600 e um músico fizer um acorde simples e depois fazendoo mesmo acorde, acrescentando uma nona no dito acorde, tenho lá minhas dúvidasse eles conseguiriam diferenciar um acorde do outro. Talvez outrosprofissionais possam explicar melhor este fenômeno. Insisto no xadrez, mas semdúvida minha aptidão está voltada à música. Segundo Dominic Miller, guitarrista doSting, "alguns acordes que eu faço poucas pessoasentendem e sentem o conteúdo deles". Talvez por isso alguns enxadristas "adoram" ouvir música erudita. Será que o motivo estaria ligado ao "status"? mais elegante? fino? À época nãose explorava, como nos dias atuais as notas alteradas. Assim, entendo quexadrez é aptidão, nada em relação a ser melhor em cálculos ou superdotados, embora reconhecer que melhora a concentração.

O xadrez por correspondência e a consulta de banco de dados com ajuda dos computadores

2011-11-27T20:38:00.001-02:00

No passado, as cartas portando os lances, viajavamquilômetros para chegar ao seu destino. Hoje, existem programas apropriadospara jogar por modalidade postal. E o postal ficou tão comum que nos celularescom sistema "android" e Iphone", existem diversos aplicativos e gratuitos paraesta finalidade. As partidas em geral podem ter duração de 1 dia ou 2 dias porlance, tempo que entendo ser o mais comum.

Um lote de cartas, livrose os micros dedicados para consulta, sendo mais difícil a consulta eseleção do lance adequado e imagino que era uma verdadeira tortura.Hoje, dispomos de bancos de dados que em segundos pode nos fornecer elementos sobre a partida. O mais usado, creio eu, é o da chessbase,pois pode-se consultar e indexar partidas, partido-se de um banco de dados demais de 5 milhões de partidas. Embora eu não seja adepto do postal, pois jogueimuito pouco nesta modalidade, aquele que ousasse dizer que fazia o lance poriniciativa própria, sem consultas, congratulo. Em partidas jogadas no passado, se solicitarmos a análise das engines, certamente vamos nos deparar com erros e erros. No passado, para os que dispunham de xadrez dedicados, seutilizavam desta ferramenta, hoje certamente utilizam do banco de dados e enginespara consulta da melhor opção.

O fato que mesmo se tendo um banco de dadosextenso e engines poderosas, quando o oponente dispõe das mesmas ferramentas, aresolução favorável de uma partida não é tão simples. Necessário a interferênciahumana. Partidas com d4, são posicionais, existem linhas exaustivamenteanalisadas por isso a necessidade de uma análise mais acurada, completa, com o auxílio do computador, algo que recentemente denominaram como "freestyle" o uso conjunto do humano e computador.

Neste teor, recentemente joguei um partida que teve o seguinte desenrolar:

[ECO "D36"]

1. d4 e6 2. c4 d5 3. Nc3 Nf6 4. Bg5 Nbd7 5. Nf3 c6 6. cxd5 exd5 7. Qc2 Be7 8. e3 O-O 9. Bd3 Re8 10. O-O Nf8 11. Ne5

No meu banco de dados, constatei 436 jogos;

Ainda, pude obter os seguintes jogos, como a seguir:

Voltando um lance, 5833 jogos!

O fato é que intuitivamente ou por repetição e consulta, o enxadrista começa a distinguir porque uma linha poderá trazer melhores resultados as brancas ou pretas.

Aqueles que gostam de estudar, não deixem de ler sobre a nova função do Fritz 13

"Engine analysis has changed chess forever. This is so obvious that many aspects are now taken for granted. For instance, a slow engine on an old notebook does not always tell the truth, and yet people only wait a few seconds before uncritically making the recommended move. Popular positions are analysed by thousands of players over and over again. This means an immense amount of time and electrical enetgy, both of which are finite ressources. Fritz offers help. Every position that has been analysed by anyone at any time is voluntarily saved on a server. The possible engine variations are then available to everyone who looks at this position. We call this system „Let's Check" because detailed analysis can be gained immediately without investing any time."

Aproveitando o texto da matéria que reproduzi neste blog, ver post anteriores, tenho algumas máquinas desenvolvidas por Applied Concepts. Por incrível que possa parecer ainda funcionam e estão em ótimo estado de conservação.

"The Spracklens, top programmers of the time, began concentrating on serious program advancement with their Applied Concepts/Chafitz Boris/Sargon 2.5 program. Chafitz marketed Boris/Sargon 2.5 as the first serious ‘tournament players’ computer in the form of the then conventional key-punch system, calling it the Modular Game System." - "créditos desta matéria pertencem a Players Chess News (1986) com atualização de Source: 11-1986, International Players Chess News: A History (Recap) of Chess Computers.

(Slightly edited by Hein Veldhuis.)

Early 1985
The latest development in chess computers for 1985 is Fidelity’s Chess Challenger 12 running at 5 Mhz. The older Chess Challenger 12 ran at 3.25 Mhz, but both machines use the same program, the Budapest. The increased speed of the Chess Chalenger 12 does not make it stronger than the Elite 4.0 which has the Glasgow program, a one year further advanced program. In other words, the increased program strength of the Elite 4.0 outweighs the greater clock speed of the Challenger 12. The new Chess Chalenger 12 increased $100 in price over its predecessor, from a list of $250 to the current list of $350. The rating strength increased approximately 50 points. Another new computer has arrived on the market, the Turbo Star from Scisys. Our computer experts are now testing this machine to evaluate its overall strength.

Late 1985
Until Fall, the Super Constellation was the strongest machine commercially available and should continue to offer the best price/performance ratio in the 2000 rating range into 1986. The latest models coming off the line have an even lower defect ratio than the initial models, which were already less than 5%. A larger version of the Super Constellation is in the works, called The Constellation Expert - expect a November delivery.
With an extra larger program than the Super Constellation (64K vs. 56K) The Constellation Expert will also feature substantial programming refinements. This should put in about 75 points higher than the Super Constellation, which has an official rating of 2018. Moreover, The Constellation Expert will be a full sized beautifully finished auto-sensory machine. But with a price-tag of $700, The Constellation Expert may have trouble meeting the sales of the popular Super Constellation, with its healthy price/performance ratio. Fidelity’s Elite A/S 4.0 remained a good buy as a beauty/brains model until the arrival of Novag’s Constellation Expert. Mephisto is back with two upscale programs, the “S” and Blitz, and five different choices for casings.

Their top-of-the-line model is the Munich S, a beautiful wood cabinet filted with costly electronica. The name “Munich” describes the 17” x 17” casing. The “S” stands for the expensive advanced program expected this Fall/Winter. Presenty, the Munich board is only available with the Blitz program. Although the “S” program is much larger than the Blitz with its 64K (and should break the 2000 harder), it is slower and hence better only at strategy. The Blitz is better at fast response, tactics, and especially problem solving. Better positional play should still put the Munich S as least 50 points ahead of Blitz. AVE Micro Systems recently released their Sargon 4.0 program. This program should not be confused with the Elite 4.0 or Prestige 4.0 program, although the casing looks very much like that of the Prestige (without the clock). The playing strength is now Class “A” (although claims over 2000 are made), a healthy class ahead of Sargon 2.5 or Sargon 3.0. The main reason for the jump into Class “A” is that the original programmers for the Sargon 2.5, the Spracklens, chipped back in to aid AVE Micro Systems. The rating is still a notch below Fidelity’s Elite 4.0 program due both to the sophistication of Fidelity’s program and its clock speed of 4 Mhz. However, with a program only slightly stronger than Fidelity’s new model costing 1/10th the price, few players will pay the premium for what is perhaps the most beautiful chess computer casing ever produced.

The dramatic development in late ‘85 is in the public arena - not in increascd playing strength (non tournament players, who constitute the biggest market, can count on loting every game against present top models and certainly don’t need anything stronger) but in improved price/strength ratio in the lower range, Fidelity’s new Excellence model would have been topof-the-line only a few years ago, doubtless carrying an expensive price-tag (the original plastic Elite listed for $1000). But the Excellence cost only about $100 with a perfectly decent playing strength of about 1800.
Chess computer manufacturers have a long history of overrating their machines. The only computer officially expert rated is the Super Constellation as 2018, yet Novag continue’s to claim a strength of over 2200. Such boasting is unnecessary since as its real strength it offers the best price/performance ratio for stronger players. Fidelity is guilty of the same exaggerations in the lower-end range with the Excellence, boasting a strenght about 200 points too high. Imagine trying to have an 1800-rated program running on inexpensive electronic components - the result could be even more quality problems than Fidelity’s expensive machines now experience. And it is not reasonable to expect the Excellence’s program which is only half the size of the Elite’s, to be as strong as that machine’s. It runs 25% slower than the Elite’s and contains only 60% of the opening moves. Also, the machine is not modular, and is incapable of accepting a large opening repertoire, or update.

The 3 Mhz clock speed is misleading since the program runs a cheaper processor yielding an even slower comparative speed. One advantage, however, of this procescor is the increased battery life: now the machine will play 100 to 200 hours on a set of four batteries.

Fidelity has plans to submit the Excellence to the USCF for an official rating, the second entrant to take this bold test after the Super Constellation. The hope is that the machine will come out with a rating over 1800, but that even if it fails significanrly short of that goal - say, low class “B”, It will still be by far the best buy for the dollar in the $100 price range, two other models are all below class “B”. The next models up, the Chess Challenger 12 and Constellation 3.6 both list for $250 and are at best only slightly stronger. Some impatient customers may still opt for the Novag Constellation 3.6 since it plays a much stronger speed chess game. Relatively speaking, the Fidelity Excellence is poor on fast response levels and needs 5 to 10 minutes per move for its strength to flourish. Other customers may opt for the handsome walnut-framed Chess Challenger 12 for cosmetic reasons, as the Excellence looks a hit like a home-made model kit.

Even the plastic Constellation series look very handsome, with a robust casing in which one can see the work of a highpowered team of designers. And the cost is not that much more - less than $100 difference after discounts (The Excellence lists for $225, plus $12.95 for the adaptor).
Stil, all in all, we feel the Excellence is the best buy for the dollar in the lower price range and will help anyone rated class “C” or below improve quickly. Ones one reaches class “B” or “A” the machine becomes more a sparring partner, useful for keeping the player on his toes.
In order to make full use of a chess computer as a tutor er self-improvement tool, its playing strength should be at least one solid class ahead of the player’s so that he can respect its advice and can plan on frequently losing and learning.

But even the non-tournament player, who can anticipate not winning on tournament time settings, will find the faster response levels easy enough to show him a win on occasion. So it makes a great gift even for the total novice (unlike the regular Constellation, which Novag should probably have built in training levels as they did with the Super since its number 1 level of 0-to-5 seconds response is not much worst than the slow response levels; on all levels the person en the street can count on losing).
Customers who cannot contend with the Excellence’s quality control have two options that were top-of-the-line models in their time, and which have been reduced substantially because they are used Great Game Machines with all three cartridges (over 1600 strength) $99.95 (including adaptor); or regular Constellations, rebuilt $175, used $125, with used adaptors, $9.95.

Stronger players (class “B” and above) and lower-rated players ambitious to reach an Expert rating (the aspiring junior, for instance) will find their best buy in the Super Connie. Experts regularly use it to keep in form - even a few Masters have bought the machine, finding it sufficient to provide a real challenge, and enough of a sting to keep their interest. Masters can utilize the programmable opening book to steer themselves into middle-games that are part of their repertoire, but pose paricular difficulties.
To summarize, our recommendations for good choices in late 1985 are as follows: Fidelity Excellence - fine for the less ambitious player and as a gift for the casual player (e.g. most people.) Novag Super Constellation - appropriate for the serious tournament player looking to improve. And with its lower training levels, even an ambitious beginner has the whole spectrum ahead of him.
Mephisto Blitz - ideal for the problem solvist. Fidelity Elite A/S - for the person who appreciates beauty and brains. You could, patience notwithstanding (= onverminderd - ongeacht), wait for the Constellation Expert.
The matter of ratings It should be noted that Novag is the only company to have their computer officially rated by the USCF computer rating agency. Most companies won’t risk permitting their products to be officially rated because of the possible bad press if theirs does poorly, The Chess Federation allows any production or experimental models to play in regular rated human tournaments (eg. U.S. Opens). However, since they cannot monitor the legitimacy of “on-market” models, all computer entrants are considered experimental. Therefore many are supped - up to their
max. One supped - up program (faring very well as such) has been made to run very powerfully in tournamcnts is has competed in, the Sargon III. Commercial models are much less impressive.

Software vs dedicated machinesSubstantially stronger than the Sargon II, the III is the best software (diskette) program out. However, since the program was designed for the casual player already owning a home computer, the manufacturer cannot economically staff a team of programmers to approach the strength of state-of-the-art dedicated models. The weaker programming in conjunction with the limitations of home computers (previously discussed) in for instance a standard Apple
computer (running at 1.2 Mhz) will play a slower, weaker game.
Still, one can achieve a 1600 level game. The diskette is a good buy, but there is still some charm lost from having to key in moves, watch the board on a screen and then move the pieces on a real board. Playing against a dedicated machine that actually “thinks” is quite different. Many people owning a home computer will ask for a chess diskette simply because they already own a computer. What they mean to ask is - What will give me a good game of chess? (g/n)

Familiarity breeds contemptSome computer owners have tent their machines in for an update (eg. up-grade to a Budapest program) and were disappointed to find that the improvement was very slight, so slight for some that the machine actually seemed weaker. This may have been due to the human having improved against the first edition and improving in the couple months it takes to get it back. However, chances are that the player was comparing his cumulative win/loss ratio on the older version (where he may have had many more initial losses) to his current record against the update. Incidentally, the Glasgow program is a more significant upgrade. Although the top program out, the Super, boasts an official rating of expert, a number of the
stronger, seasoned chess computer vets on gut feeling estimate after a solid month with the machine, even its strength to be slightly under 2000, high 1900’s (without utilizing the programmable opening book).

These prosusually underate chess computers by far more thans 25 to 50 rating points. Maybe they need more time to attempt uncorking any quirks they may discover. These hard cores know exactly how to play against computers. The human player has a distinct advantage – he learns how to play against the machine, even subconsciously picking up on its weaknesses.

Two human opponents playing regularly against each other will attempt different lateopening/middle game lines and after the orther sees that he is losing, he adjusts and unleashes a different middlegame strategy. So, the ultimate goal is to produce a machine varied enough, good enough that you never catch on to his tricks; you can never learn to beat it automatically. Lacking that, a machine that learns to play against you. Well the Super has achieved the goal on both counts to some compromising degree. Opponents will find that they are actually improving, not just uncovering weaknesses in the machine. With the earlier, weaker models, once you discovered certain failings (entire books elaborate on these deficiencies), you could beat it at will.

Players would go through all kinds of contortions trying to make the machine’s game better, such as opening up files one usually wouldn’t, playing unsound sacrifices, or just playing an inferior game. With the Super’s advanced middle game and endgame positional understanding, its weaknesses are much more subtle (a master’s are even more subtle) and hardly as predictable. To most people the machine is unbeatable (excluding training levels of course). But for the expert or master, as they try different lines and find ways of outwitting it, i.e. learn the machine, it won’t quite learn back. However, with the owner’s assistance the computer can, in a sense, learn how to improve on its play and “learn” to beat its master. No long does familiarity with a computer necessarily breed comtempt. The computers now are so good that even after becoming intimately familiar with their style, their playing strength remains about the same.

Elite A/S dilemmaNow the more costly Elite A/S (Budapest) only had beauty to show for itself as it was ranked third behind the Super Constellation and the Elegance. It was more closely grouped with the Constellation 3.6 and the Chess Challenger 12 in plaving strength. A good number of
people found that the never expected to beat the Super Constellation or the Elegance, or had any realistic aspirations of doing so, They did not like the flimsy pieces on the Elegance, the plastic of the Super Constellation and liked the size of neither. For them, the Elite A/S Budapest was fine.

The main real advantage to getting the strongest program for someone at that level is that although he or the never plans on getting to the point of bearing the machine regularly on its higher levels, as least the machine will be providing a better game on fast response levels. In addition to receiving a more challenging game without having to wait, also the stronger the machine, the less likely the chance of outgrowing it.

Fidelity Elite A/S Challenger

Study by K.K. Behting, 1908

White plays and draws! Artificial Stupidity?

Naturally, if one is using the machine as a tutor, one inclined to take the advice of a stronger program with less of a grain of salt than a lesser program. The machines are so strong now, however, that most people can start to make compromisses between top strength and top looks. Still some players wanted the beauty and a program ranking closer with the top models. Shortly after Novag released their Super Constellation, Fidelity released a third version of the Elite A/S. The program is exactly that of the Elegance’s, However, is runs 0.4 megahertz faster (3.6 versus 4.0 Mhz), resulting in only perhaps a 10 rating-point gain. This program at
4.0 Mhz is 50 to 100 points stronger than the older Elite A/S Budapest, putting it close to 1900. So the dilemma was solved with the Elite A/S 4.0 ranking solidly in the top two. The cost went up only $50 ($650 list), a healthy price/strength raise.

With a list price close to the Super’s, the comparison is easy-expensive, handsome cosmetics (beauty) versus costly electronics/programming (skill).
Elegance vs Elite A/S 4.0

With a difference of $250 in price, the Elite/Elegance comparison is a little muddled.
1) Playing strength is approximately equal, both as solid class
2) Playing surface of Elite 4.0 is almost tournament size, with beautiful wooden pieces, making for much more comfortable, natural playing.
3) Both machines have a modest number of built-in opening moves (several thousand) intended to be supplemented with any of Fidelity’s opening cartridges, such as the CB9 ($78 list) with 8,160 moves or the CB16 ($120 list), with 16,100 moves. (The Chess Challenger 9, incidentally, will only accept these two). The newer Fidelity models (such as the older Prestige Challenger, all three Elite A/S’s, the Sensory 12 and Elegance) will all accept these two general opening cartridges and the more specialized ones.
Also offered is the 5-volume ECO (Encyclopedia of Chess Openings) set (each volume, $120 list) or the even more specialized Queen’s Gambit Tarrasch module ($120 list).
4) Unlike the Elegance, the Elite 4.0 has a built-in displayed chess clock. Besides the obvious telling of time, one can see a number of insights the machine is trying to relay.

Fidelity Elegance Chess Challenger

For instance, it will display its assessment of the position in + or - fractions of points (+ 0.5 means it feels it is up the equivalent of half a pawn as a positional/material equation. It does, occasionally, display minus scores - this is to make the human opponent feel better). The clock will also display which ECO opening module should be popped in next, in the event that a line should cross over to a different ECO volume (a rare occasion, and only useful if one owns the ECO cartridge set, $600 list).
5) The Elite 4.0 has a long-term memory (as the Super Constellation),whereas the Elegance is only short term.
6) The one advantage of the Elegance is that is has no voice. But rest assured, the voice on the Elite A/S can be turned off. Actually, the voice may have a positive influence in stimulating the interest of a youngster to tackle the game.

Opening enhancement

All rating estimates given so far have been based on the machines performance without utilizing any opening enhancements. The following comparison of these enhancements is primarily between Fidelity’s complete set of ECO cartridges and Novag’s programmable opening book and how they relate to the two primary aims of the opening ‘book” of a chess computer:
1) to play these automatic moves quicker and
2) to create more difficult middlegame opposition.
We as Players feel that, in general, the opening is the least important phase of the game. One of the primary reasons for increasing one’s depth of rote knowledge of an opening repertoire
is that is simply allows one to budget extra time to more signifiant middlegame and endgame considerations. The set of ECO cartridges for the Fidelity machine override the much smaller,
built-in lines and increase the average depth of many lines to over 10 moves, setting the machine in motion for a decent middlegame.
The set is especially good for beginners as they can see if the moves they are making are respectable enough to be considered a main line (the cartridges contain only the main ECO lines). However, the entire set probably increases the overal strength of the machine by only
25 points. Additionally, while ECO may assess a line as being slightly better for White, equal, etc. these assessments do not have the same meaning for every player. “Good” and “Bad” positions are relative terms.

More important than speeding up the opening with a vast collection of opening moves to reach relatively even positions is to have the moves continue into the middlegame with significant effect. Thus, the ECO set for Fidelity is less effective than Novag’s programmable opening (more appropriately titled programmable middlegame) feature, since the Novag approach may be used to specifically affect only the middlegames in which the user needs
practice. This approach has great significance for the serious student. Imagine that every game played resulted in a middlegame where you found yourself having to struggle, not just any randomly selected middlegame, but specificalty the ones that occur in
your opening repertoire. Every player finds that there are lines within his or her repertoire that cause more difficulty than others. One lessen to be learned with a programmable middlegame is how to steer the opponent away from these more difficult lines when thev are encountered in tournament play.

If this is not possible, using the computer the player is able to learn how to counter and/or handle these difficult middlegame positions through regular practice. Let us continue this example in greater detail. Imagine, if you will, the average master playing against an expert. If the expert is playing an opening where the middlegame plays itself (e.g, a thematic kingside attack) and the master bas been steered into his least favorite line, suddenly the expert is playing at least 100-200 points stronger than his usual play.
Similarly, if a 2200 rated player was playing the 2000 rated Super Constellation and programmed in to enter only middlegames he despised playing, then the strength of the computer goes up in like manner. Of course, the next player with his own repertoire who sits
down to play the machine will find its strength back to the original, because the machine is only stronger specifically against the person who programmed it. With the Super Constellation this is achieved by first changing the ratio of rcsponse of the 21,000 moves it comes with. Undoubtedly some of the machine’s lines will provide you with difficult middlegames to play against with either color, After you select the cream of the crop, the most difficult lines the machine has against you, specifically (probably a total of several
hundred or more, depending en how varied your opening repertoire is), then you add other lines of your choice which are designed to pose you with difficulties. This process of aiding the enemy works like an inoculation. Thus, curiously enough, the 2400 programmable half moves of the Super Constellation are more significant than the tens of thousands of ECO moves contained in the Fidelity cartridges on both of the opening qualities discussed earlier:1) the game generally goes deeper into the middlegame, gaining time for later analysis and 2) the middlegame opposition is tougher.

To conclude: The Fidelity ECO system is good for the intermediate player to help widen his or her opening repertoire. For the, beginner or intermediate player who purchases the Super Constellation, the assumption is that the student will learn from the built-in book lines and from a library of actual books. The student has probably set his sights On reaching expert or master rating and will find the machine with its own book challenging to that point. When he reaches his goal (or perhaps even at Class A) the owner can then take the time to boost the machine’s strength with the programmable option (also by that time there will probably be slight up-date on the overall strength of the machine).

1982

1982 saw Fidelity take the lead in sales of chess microcomputers to tournament players. Novag was busy working on improving their programs. Applied Concepts introduced an opening module (the Gruenfeld, priced at $100) and an endgame module (Capablanca, $160) which only managed to take the strength of the entire system, priced as $600 to a low Class B rating of 1600. SciSys updated the Chess Champion Mark V to their (Philidor) Chess Champion MK VI program, which proved not to be significantly better than their original. Prices dropped to an all-time low as rating strength stabilized.

It should be noted here that all rating estimates are based on tournament time controls of 40 moves in 2 hours. This distinction will become more important as we discuss later the newest machines whose. ‘blitz’ ratings may exceed their tournament rating by as much as 200 points. Fidelity’s 1982 introduction of the Chess Challenger 9 was designed to “blow away the market” at an introductory list price of $165. Later the list increased to $195 as the coat of electronica in all areas increased. Prices have continued to increase with each new generation of strong machines.

Even so, the Chess Challenger 9 was a strong and affordable machine, with the same brains as the Champion Sensory Chess Challenger but as half the price. It was 1982’s best buy based on dollar to performance ratio. The Chess Challenger 9, however, did not have either a wooden frame or a build-in clock.

Fidelity Champion Sensory Chess Challenger

Fidelity did finally decide to add the modularity (not to be confused with the Modular Game Systems) concept to the Chess Challenger 9. The MGS was designed to accept program updates (brains), while Fidelity’s could only be defined as modular, accepting raw information (opening cartridges, etc.) but not updatable. This means that to significantly improve playing strength the whole machine had to be sent to the factory for the guts to be replaced. Now it was possible to purchase a strong program (about 1600) at a low price or pay up to the list price of $600 for the Applied Concepts system, rated at 1600+. (g/n)

The Conchess line of computers made an appearance with three inexpensive models, all with the same program. rated at approximately 1600. There were three levels of size (Escorter/Ambassador/Monarch) and craftsmanship, ranging in price from $250 to $400. Early in 1982, Fidelity also came our with the Elite Sensory Champion, a machine for those who wanted the best available program. The machine was basically an advanced version of the Champion Sensory Chess Challenger program, running at 3.6 Mhz. The stronger Elite Sensory Champion program and faster clock speed put the playing strength at high Class B (almost 200 points stronger than the Chess Challenger 9).

The limited edition of 500 pieces has long since sold out at a list price of $1000. Later in 1982 Fidelity produced the Prestige Challenger, the same basic program but in a much nicer housing (similar to the Auto Response Board previously discussed), with an internal chess clock and a price rag of $1295. So, 1982 offered the tournament chess player three good choices: Chess Challenger 9, a low priced machine with decent strength; Conchess, with a nice casing and decent strength, and Prestige Challenger, a top-of-the-line machine combining beauty and brains.

1983

In early 1983, the main choices remained Chess Challenger 9 and Prestige Challenger. But for spice, the German firm Mephisto came on the American scene, offering a machine which fell somewhere between the Chess Challenger 9 and Prestige Challenger in both price and strength. The Mephisto II, a hand-held model, list for $350 and had a solid B rating of 1700.

A beautiful cabinet for the machine, with out additional “brains”, sold separatly for $550. Other manufacturers appeared to be doing nothing. Is was becoming obvious that updatability did not have much meaning, with regard to the strength of any individual machine. It had more to do with the future of the particular company, their programmers and their updating ambitions than any real potential of the machine. Suddenly in the Fall of 1983, after a long quiet period, Novag unveiled their new Constellation (2 Mhz), and also announced plans for their Super Constellation (first 3,6 MHz and later 4 MHz), which would make its appearance in 1984.

At a list price of $199.95 and solid “B” strength, the Constellation put the Fidelity Chess Challenger 9 and the Mephisto out of contention. Also, Kittinger had spent all his time working on developing program modifications which allow the machine to play an especially strong game on its first level with up to a five second response time. Another especially welcome improvement was Novag’s sensor board, which is far more sensitive than the competitor’s pressure sensitive boards. Entering moves on the Constellation, thus, falls somewhere in between the hard press of the sensory games and the ease of the Auto-Response.

Additionally, by eliminating the response lights on each square which are typical of pressuresensitive boards and replacing them with prompt-lights on the proper coordinates, Novag succeeded in eliminating one of the more distracting features of its predecessors.

Concurrently, in late 1983, Fidelity brought the cost of the larger wooden sets down with the Elite A/S (Elite Auto-Sensory); similar to the Prestige Challenger in operation and playing strength at one-third the price - $450. This was the lowest price ever on full size sets. So, at the end of 1983 the two top programs offered at good prices were; in the inexpensive version, the Novag Constellation, rated around 1700 and listed for $200, and in the expensive range, the Fidelity Elite A/S, approaching 1800 and priced at $450. (g/n)

1984

Early in 1984, Fidelity discontinued the 1983 Elite A/S model and put their Budapest program into the Elite A/S casing, calling it the Elite A/S World Champion. This was a well-deserved title, since Fidelity had just won the 2nd World Micro-Computer Chess Championship in Budapest, Hungary, a few months earlier (late ’83). The Budapest program brought the machine solidly over 1800. Customers with older Prestige Challenger machines or the Elite A/S could send the machines to the factory for $150 up-date, and first time buyers paid $600 list. Immediately after the Elite World Champion came out at Class A strength in mid-1984, Novag stepped up their Constallation program to run twice as fast (from 2,0 to 3,6 Mhz), bringing its strength up to Class A also.

For an additional $50.00, everyone opted for the Novag Constellation 3.6 (‘Connie 3.6’ $250) and the slower verson is now discontinued Programmer Kittinger’s emphasis has always been on speed, and now not only were the heuristics designed to play exceptionally well at fast speeds but the chip speed was running faster. The speed chess level was almost 2000 strength (based on human opponent spending as much time, moving as quickly as the

machine), while the tournament level strength was low Class A (1800+).

All these statistics were taken at the time the machines appeared and continued to hold up in tournament competition throughout the world, against humans and against other chess micros. Of course the manufacturers still get a litlle excited about their own products. For instance, both the Constallation 3.6 and Fidelity Elite A/S (Budapest) claim to be rated over 2000 by their manifacturers. Well, perhaps the Constallation 3.6 is close at speed chess, but at 40/2 both had just entered Class A. Even so it seems now that rating claims are overstated much less to than years before.

Late - 1984

At the end of the first half of ‘84 the 3.6 was heralded as being the best priced machine for the

playing strength, just as the Chess Challenger 9 was in ‘82. The Elite A/S (Budapest) was

the other tournament player’s choice for those opting for a more beautiful casing. It was

becoming clear that Novag and Fidelity were the two to watch. Fidelity produced two

attempts to compete with Novag.

1) The Chess Challenger 12, and Elite A/S downgraded both in strength (close to 1800) and cosmetic appeal (half size with imitation metallic look and wooden border rather than full wood surface). The price was brought down to the Novag Constallation 3.6’s $250. However, the Constallation 3.6 stil remained king in that price range.

2) The Fidelity Elegance, also in the 12’s size, but much more handsome, retaining the Elite’s full-wood look, was quite an improvement both in appearance and play. The pieces, however, lacked a touch of class, It’s program was an Elite A/S update, running at the same speed (3.6 Mhz) but with better programming. The Elegance program just tied for first in the

Fourth Micro Chess Championships in Glascow, Scotland, August ‘84 and appears to be close to 1900 strength.

Just as the Elegance was coming out, Novag relased their long-awaited Super Constellation. The list price was expected to be $600.00, but Novag surprised us with in incredible low list price of $399.95 ($600.00 with printer and clock). The other surprise which Novag had kept well secret was the fact that the machine is now user programmable. The biggest surprise, however, came late November when the USCF officially acclaimed the Super to be expert strength. After 40 games of humans (average rating 1982) playing against 10 production offthe-shelf models, the computer garnished 22 points. This 55% score under tournament conditions netted in official rating of 2018.

Super Constellation vs Constellation 3.6

Some of the main differences between Novag’s Constellation 3.6 and Super Constellation are:

1) 16 levels for the Super (7 lower levels so one can win occasion), while only 8 for the 3.6 (and no training levels). Tournament players like this feature since they can teach wife/husband or kids to play the game and, after not to long, they will start winning and be encouraged to move up the latter. The Constellation 3.6. for instance, would start off on its lowest, instant response level by beating even intermediate players a hundred games in a row.

After such a string of losses, the average person becomes disenchanted and feels like he’ll never be able to play the game competently. We suggest that if you get such a machine, plan

on losing - against is every time, use it as a tutor. Then trounce your human opponents. The advantige of the Super, of course, is that you start monitoring your progres by seeing a ratio of wins as you go up the “easy” levels. Also if you set a goal of, say reaching expert strenght, you can progress in smaller increments and have the machine stil keep you interested even when you reach your goal. And you’ll always have the lowest levels to beat up om if you even find yourself disenchanted with progress. For anyone rated below 1600 the choice between the 3.6 and the Super would be easier if the Super were presently priced at $600.00. However,

with the current cost being so closc the two main factors appear to be

a) Can one handle losing every time against the 3.6 with no out, until improvment finally shows through and b) is your goal to have a good, strong partner (if you don’t mind losing) or a tutor that can help you set your goal at expert/master class rather than class ‘B’.

2) The Super is compatible with the Novag printer, while the 3.6 is not. If you find that you have played a particularly brilliant or instructive game, you may print out the game in crisp figurine notation with diagrams at instructive points. The printer may also be used to verify positions in the computer’s brain or keep track of which opening variations one has programmed in.

3) The Super accepts a clock for a more even match. Masters may spot time odds of five minutes to three for an even struggle (the machine has been nick-named “blitz monster” after winning games against IMs in blitz matches). Weaker players may give themselves the time advantage. The clock may also be used singly for tournament chess, or to play speed chess with friends.

4) The rating difference between the two machines is close to 200 points. Opening play is much more varied with over 21,000 moves versus 3000. This should result in a better middlegame starting point. The program has been written in a 56K format as opposed to 16K. This allowed the programmer much room for advanced strategie heuristics. Now its positional insight is more equal to its proverbial tactics. It will even sacrifice on positional grounds. The endgame play is also much more enhanced. It will force a mate with bishop and knight versus king, a feat no other computer can perform and many experts find difficult!

5) The internal clock speed is only 0,4 megahertz faster (3.6 Mhz versus 4.0 Mhz). This is much less significant than the drastic program advancements as it very rarely allows it to see even an extra ply (½ move) further. The fact that the machine plays a strong expert, close to master speed-chess game has more to do with the promming.

6) The Super can be unplugged and the game still continued three months later, due to its long-term CMOS memory. Thus, if you wind up in a losing position and “accidentally” knock all the pieces over or trip over the cord ... well, the machine is still ready and willing to continue.

7) If asked, the Super will display its depth of search at that moment. It also automatically announces up to mate-in-four. If you are plaving along when unexpectedly on comes the mate-in-four signal, you know already that it is time to hit the “take-back” key (followed. perhaps, by the “hint” key).

Novag Constellation 3.6

8) Both solve mates and problems with amazing swiftness. Often, the Super will solve the problem in seconds, faster than some Grandmasters!

9) With the Super, one can in effect aid the programmer by adding opening lines that you, specifically, have a more difficult time against and need practice playing, either as White or Black. You can also program in how often you would like to see each line appear. Now if you find that you need to get a few fast wins in against the computer, just put in a couple. You could have it open 1. g4 every time and after your 1 ... e5, have it play 2. f3 50% of the time and 2. f4 the rest of the time. After mating it a number of times on h4 and proving it is not invinceable, you can erase those moves from memory and do some serious programming. The moves do not just stay in memory for a limited time. Rather, they become an integral part of the machine’s permanent opening memory repertoire (although, of course, you can erase and reprogram this repertoire).

Entering the moves into the computer’s bram is easy. It does not involve laborious keying-in. Just play the garne naturally and each move you play is automatically ingrained into its brain, as long as you are in programming mode. You can create your own monster - the variations you dread playing will keep coming back in future games to haunt you. You may find after drilling yourself through many games that certain variations you used to have a difficult time
playing against you now find easy to play. At that time you may steer the machine much deeper down the line to a fork where you feel that the branch the machine usually opts for poses fewer problems than one it plays less frequently (or perhaps the friend you’re trying to beat plays the less frequent line). At that fork you can change the ratio of response - have it play the move it usually opts for only 1 in 10 times, and the other move, 9 out of 10 times. If you ever find that you master the line altogether then you may delete that line leaving space for others. The deletion flexibility is especially important if you are close to the programmable moves, which is 2400 half moves. This programmable feature is only of
optimum use to stronger players who are objective enough to recognize their own weaknesses. Weaker players who purchase the Super and hope to get to master strength can utilize this feature more fully as they go up the ladder.

1979

In 1979, prices dropped to the $100 range. Machines such as the Fidelity Chess Challenger 7 and Applied Concepts Boris Diplomat were released with no real strength improvement. The next playing strength sophisticasion came with the Fidelity Voice Chess Challenger. The rating went up about the same as the price (200 points). Gimmicks such as the voice, or machines with little, snide messages running across a screen, were meant to uplift an otherwise unchallenging game. These “innovations’ were a questionable use of the added memory space, which could have been devoted to a more challenging level of play or at the very least an improvement on move entry technique. Moves still had to be entered on an external keyboard, leaving much room for error and “illegal” moves. Additionally, it was still possible to enter the moves correctly on the keyboard yet position pieces incorrectly on the playing board.

1980

In 1980, Fidelity came out with the first sensory touch board, the Sensory Chess Challenger 8. Now moves could be entered directly on the board by pressing the piece to be moved first on its starting square and then on its destination square. The board, however, required a concentrated, firm pressure on a precise point; nevertheless, this technology was far superior to the external keyboard method of entering coordinates, eliminating the possibilities of keying errors or move errors discussed above. Additionally, it went a long way toward eliminating “illegalities” in moves. The price dropped back to the $100 range, while playing strength advanced to slightly over 1200.

The novelty of having a machine that simply “made legal moves” wore off quickly, and designers now began developing strategy on a higher level, incorporating time controls and enhancing combinational considerations by the machines. These “toys” were good gift giving items for beginners, But even non-tournament players found themselves straining for a good game by giving these computers several hours per move (?!). Most players were still
disappointed with the weak responses.

Applied Concepts/Chafitz Boris/Sargon 2.5
(foto: Tom Luif)

The Spracklens, top programmers of the time, began concentrating on serious program advancement with their Applied Concepts/Chafitz Boris/Sargon 2.5 program. Chafitz marketed Boris/Sargon 2.5 as the first serious ‘tournament players’ computer in the form of the then conventional key-punch system, calling it the Modular Game System. The system could be up-dated with additional insertable modules. Chafitz also marketed a fancier version of its system (a state-of-the-art program in updatable format) called the Auto-Response Board. This beautiful wooden board, still available, incorporated magnetic reed relay switches below each square.

There were magnets in each piece, which responded to the magnets at the squares. Of all the machines of its time, the Auto-Response most simulated play with a human, sinds all that was required was to move the piece (no pressing squares) and the magnets recorded the moves. At $800, the machine was by far the most costly of its time. As a 1400-1500 rating, both machines played Class C chess. A less powerful program, the Sargon 2.0 was made available

for Apple Computer owners. The 2.0 was a less challenging opponent, both because is was an inherently weaker program and because is was software intended for a general computer rather than a dedicated system.

1981

Fidelity started the year with their Voice Sensory Challenger in an attempt to compete with thc top of the line machines. The machine, which integrated voice and sensory technology and included a built-in chess clock, was contained in a plastic casing surrounded by a wooden framed. The price ranged between $300 and $400. However, even with the additional features, tournament players still preferred the Chafitz’s Modular Game System for playing

strength and updatability. 1981 proved to be a year of many changes for computer chess.

Chafitz discontinued marketing and distributing their two chess computers. Thus, the two manufacturers, Applied Concepts (Modular Game System), and AVE Micro Systems (Auto-Response Board) started marketing the machines on their own. However, in

the confusion of the break-up, the top programmers, the Spracklens, ended up working for the largest manufacturer, Fidelity. It is important to note that, at least for marketing to tournament players, the programmer is the most important element, even for some multi-million dollar companies. Today’s battle is really between which individual programmer will refine and enhance his program to the best possible playing strength and variety.

Fidelity’s main sales were of lower-end products until Dan and Kathy Spracklen joined their team. They brought improvements in programming which virtually assured Fidelity’s top position. Applied Concepts was also improving the quality of the product, with the Morphy Edition master chess, which was a few points stronger because of middlegame improvements. Morphy Edition master chess increased the strength of the Boris/Sargon 2.5 to an approximate playing level of high 1500. Morphy Edition master chess was available for about $100 as a program up-date, which was a pleasant boost for owners of the Modular Game System. Additionally, they changed the name from Modular Game System (MGS) to the Great Game Machine (GGM).

Also in 1981 another pioneer programmer was busy working for Novag. This slick company made its first strong appearance in America in 1981 with David Kittinger’s “My Chess” program. Introduced in their Novag Savant machine, a hi-tech, touch sensitive LCD board with a rating of approximately 1500 and a retail price of $625, the program ranked close to the top but was relatively inaccessible because of price.

Novag Savant

The same was true of Novag’s Robot Adversary, which was an elegant machine priced at approximately $1500 (about $1.00 per rating point). Both of these machines were ahead of their time cosmetically, winning the prestigious New Product Award. However, the price/skill ratio was less appealing.

Novag also introduced a weaker, smaller “My Chess” program (only 4K) in a hand-held machine called Micro Chess. Priced as $140 with a rating of approximately 1000, this was the only significant hand-held chess computer of its time. Kittinger had just moved from Alaska to Los Angeles to continue his programming while making use of additional input from strong masters. The Hong Kong based SciSys also made an appearance in December of
1981 with their Chess Champion Mark V. Programmer David Levy’s best effort won the 1981 ‘World Micro Championship, Commercial Section. To wrap up this significant, year - all the companies top-of-the-line programs were nose to nose at a high Class C, nearly 1600.
This included Fidelity’s last quarter advancement after the addition of the Spracklen team. During those few months, Fidelity added approxiamtely 200 points to its best machine to meet the competition with their Champion Sensory Chess Challenger program.

The final 1981 retail price standings, with all machines rating at approximately a high “C” level, were: Fidelity Champion Sensory Chess Challenger $375; Applied Concepts Great Game Machine (MGS/GGM) with Morphy Edition master chess $350; SciSys Chess Champion Mark V $398; Novag Savant $625.
At this point, all the machines were straining to become a solid Class B strength. However, although all manufactuers are now familiar with actual ratings, most of them were claiming “unofficial” ratings of 1700-1799. Things had gotten to the point where if any manufacturer claimed thereal strength of their machine, which would have realistically been under 1600, themachine would have appeared to be weaker than any of the competition and therefore unmarketable.

Talvez resida nesta matéria um dos textos mais ilustrativos e didáticos que pude contemplar, obviamente respeitando os demais. Por ser extensa a matéria, vou inserindo aos poucos, obedecendo a ordem cronológica.

1976 ~ 1978 (g/n)

Since their inception in 1976, commercial chess playing machines have consistently improved in playing strength, reliability, appearance, ease of operation and price. The main point of discussion in this article will be the price to rating strength ratio of machines on the market.

The latest crop of these machines offers one entering the Expert class, two of solid class “A” strength, with two others bordering on low class “A”. Curiously, the rating of a computer is not as stable as one might expect. It fluctuates more so than the average human due to two factors:

1) whether the opponent is basically a strategic or tactical player (and other more subtle “playing style” considerations),

2) how used the opponent is to playing against computers and more specifically, against the computer at hand

The human who has been playing regularly against different machines can probably count on a new machine playing about 100 points below its “real’’ rating against him. And after playing a lot of games specifically against the new machine he can possibly substract 50 points, once he gets to know it. It’s no wonder the top computer out now, the Novag Super Constellation (officially rated 2018), which regularly beats experts, only seems to a computer vet to be in the 1900’s. Granted it is a strong expert at speed chess. In order to understand where chess computers currently stand, however, one must have a sense of the history of the development of chess microcomputers.

Fidelity Chess Challenger 1
(foto: Tom Luif)

The first chess computers appeared in the late 1970s. These included the Fidelity Chess Challenger 1 and Fidelity Chess Challenger 3, as well as Applied Concepts Boris (a small

wooden model). The mere fact that these toys could “think” was a novelty which caught on quickly with the general public. However, with ratings of below 1000 these early computers were less than challenging and therefore of little interest to the tournament player.

When manufacturers claimed various rating strengths for these machines, i.e. beginner, intermediate and expert levels, they were demonstrating ignorance of the meaning of ‘expert” rather than any attempt to deceive the chess playing world. In fact, the most primitive of these machines would not capture en passant, castle or promote properly. One machine, now classic, had the alphanumeric system backwards, with letters for the ranks and numbers for

the files. Nonetheless, these primitive patzer machines, which sold for under $400, were a good beginning for what has become an exciting and challenging application of computer technology to the high logic of chess. Most of the available machines were manufactured by Fidelity and Applied Concepts.

Two companies, Tryom with the Electronic Chess and DataCash Systems/Staid with the CompuChess (started up solely for the purpose of making chess computers (although Tryom also produced a backgammon model); however, they could not keep pace and quickly dropped out of competition when Fidelity came out with their Chess Challenger 10 which ranked over the 1000 rating.

Alguns jogadores afirmam que sendo superiores não dão importância em truques de abertura. O fato reside na hipótese que mesmo sendo melhores e com repertório de armadilhas, partem do pressuposto que os oponentes com rating considerável evitam possíveis armadilhas.

Kasparov, geralmente em simultâneas, via de regra propicia estas armadilhas com o propósito de ganhar rapidamente. Neste vértice, veremos como se comportam as máquinas dedicadas, haja vista um vasto repertório destas "pegadinhas".

DGT trabalha muito bem com ShredderChess.Apesar desta engine ser um monstro, pode-se ajustá-la em níveis adequados. Acredito que contem instruções melhores que Fritz pois comete blunders como um humano. Quanto ao modelo serial do DGT, proporciona uma conexão segura e com um cabo de 75metros, pode-se jogar sem que o DGT esteja perto do computador.

Scid Pocket v 4.1 com Citrine

2011-10-23T19:20:00.003-02:00

Lamenta-se que o prosseguimento do desenvolvimento do Scid Pocket foi interrompido. A nota do autor diz o seguinte:

All back office Scid code has been ported to Pocket PC (even book handling and tablebases).

However, due to changes in Pocket PC architecture Scid Pocket will not run on newer Windows Mobil devices and further development has been stopped.
Until now, implemented features (non exhaustive list) :

- engine analysis, with the display of up to four best lines
- board setup
- load/save of Scid bases
- opening books
- several bases can be opened with the possibility to switch between them
- import of PGN files and export of Scid bases to PGN files
- game navigation with variations handling (tap and hold generates a right click in PGN window, triggering the same contextual menu as in Scid)
- search (position, header, material & patterns). All Scid search features are available.
- opening tree (stats related to current opened base)
- engine tournament (several engines are available in installation package)
- play on internet (freechess.org also known as FICS)
- automatic game annotation by engine
- Novag Citrine external board (trough Bluetooth)

A versão disponível no site Scid funciona com algumas ressalvas quando conectado ao Novag Citrine. Com Windows Mobile, tive problemas para carregar as engines.

O que não está claro, é como a interface Scid Pocket gerencia o tempo de jogo. Após alguns testes algo sinalizou que o tempo era parametrizado no Citrine, mas ainda preciso conferir. Ainda, com as engines disponíveis no Scid Pocket, percebi alguns bugs quando conectadas com o Citrine, algo como se a força da engine não fosse a real, ver partida abaixo, como estipulada no site. Não resta dúvida que Fruit joga muito mais do que mostrou no Scid. Mas dá para se divertir com elas.

Neste teor, será que dá para concluir que o tempo do Ipaq ou Windos Mobile terminou? Há relatos de programadores sobre as dificuldades em desenvolver programas de xadrez para WM7. No Ipaq, temos várias opções, tais como a conexão com DGT e outros tabuleiros. Desta forma, talvez os futuros desenvolvimentos sejam destinados para os sistemas IOs da Apple ou Android. Mas quando se fala nestes sistemas, devemos associá-los com os celulares ou tablets que utilizam este sistema operacional e via de regra a conexão seria por bluetooth e a instalação não seria cômoda como no Ipaq. HP, detendora dos Ipaqs não sinaliza com novos modelos, então fica o impasse, ou seja, como prognosticar o futuro com programas de alto nível para o xadrez, tais como Pocket Fritz, CEboard, Pocket GrandMaster, dentre outros. Vale ressaltar que Chessbase já lançou programas para rodar no Android e Iphone, no entanto somente é possível baixa-lo no pais de origem.

Ultimately, what separates a winner from a loser at the grandmaster level is the willingness to do the unthinkable. A brilliant strategy is, certainly, a matter of intelligence, but intelligence without audaciousness is not enough. Given the opportunity, I must have the guts to explode the game, to upend my opponent's thinking and, in so doing, unnerve him.

So it is in business: One does not succeed by sticking to convention. When your opponent can easily anticipate every move you make, your strategy deteriorates and becomes commoditized.

Além de pensar, Kasp faz preparo físico. Outro detalhe, verifiquem os tabuleiros, todos conectados via serial - DGT. Como tive paciência para ver o desenrolar da simultânea, constatei que muitos destes oponentes poderiam ter abandonado muito antes, já que estavam totalmente perdidos. Por óbvio, Kasparov foi elegante em ter que aguentar a proceder lances óbvios, levando os oponentes ao cheque mate, e que poderia ser evitado o dito desgaste.

DGT serial x DGT USB

2011-10-08T23:07:00.002-03:00

Difícil opinar qual seria a melhor opção,visto que a versão serial permite com o adaptador USB, proceder a conexão com aporta USB trabalhando sem problemas. Talvez a versão serial tenha uminconveniente, qual seja, precisa ser energizada com 9 volts, como mostradaneste vídeo. Como possuo as duas versões, talvez a versão serial seja maisrobusta, quando se trata de conexão, mas depende do hardware que o usuário possui e asfinalidades desejadas com o DGT. Com a versão serial, pode-se fazer a conexãodireta com os programas de xadrez que rodam no Ipaq, ver foto acima, versões windowsmobile 2003 até windows mobile 6. Ressalta-se que os Ipaq ou smartphones quepossuam WM 7 e superior, estes programas não rodam, mas necessário conferir.Pocket Grandmaster, CEboard dentre outros, são excelentes.

Sobre o Super Expert A (convertido para C) Super Expert B (convertido para C)

2011-10-02T01:31:00.003-03:00

Como se pode notar nas fotos, o Super Expert A, convertido para o programa do Super Expert C, não contem as pontes, fios entrelaçados como é o padrão no Super Expert B e C. A razão de tal fato, por dedução penso eu, prende-se ao processador do Super Expert A que vem equipado com a série 65C02-P4, ou seja 4 MHz. Ao contrário, Super Expert B e C, já possuem o processador com 6 Mhz, W65..P6. Concluindo, as pontes se devem, penso eu, ao ajuste da energia, já que o processador de 6 MHz precisa de mais voltagem para trabalhar do que o processador série 65C02. Por derradeiro, qualquer contribuição é bem vinda.

DGT - software 1.8 e peças profissionais

2011-09-26T09:51:00.000-03:00

DGT possui uma série de modelos de peças. Destaco três delas:

As peças "timeless" e "classic" são as mais usadas. Nesta postagem, o tabuleiro figura com as peças "classic" e versão - eprom 1.8. Ao contrário dos demais tabuleiros eletrônicos, cujas as peças contém imãs na base, DGT usa tecnologia diferenciada, com patente reconhecida, ao contrário de imãs. Na base das peças existe um sistema eletrônico para o reconhecimento das peças no tabuleiro. Por isso, há quem diga que as peças não poderiam conter o peso desejado, tendo em vista que chumbo ou ferro, poderia interferir no dito reconhecimento. Aliás, este reconhecimento de peças com essa tecnologia não se constitui em novidade, pois no passado, tabuleiros como o Tasc e Bavária, já dispunham deste reconhecimento, ver em:

website Ismenio

Entretanto, no que tange ao Tasc, na minha opinião o melhor tabuleiro já construído, há quem diga que a fabricação foi interrompida por problemas de patente, porém, há que conferir. No momento, espera-se a conclusão do projeto da http://www.phoenixcs.nl/index.php que promete o tabuleiro com 81 leds e com a tecnologia da DGT, veremos. Particularmente, creio que este produto será destinado para uso não profissional, Desenvolvimento Ruud Martin visto que em torneios, principalmente para jogadores com pontuação elevada, seguramente os leds poderiam criar problemas. Digo isso porque certa vez disse Karvov: "após 3 horas sentado jogando uma partida, qualquer luminosidade fora dos padrões normais incomodaria" e ver um led piscando, sinceramente não saberia dizer qual seria a reação de um jogado com rating igual ao dele.

Para quem deseja adquirir, sugiro a versão eprom 1.8 ou superior.Com a interface Arena, Fritz, Chessbase, dentre outras, DGT trabalha muito bem, ressalvando que algumas engines, aquelas mais fracas, costumam travar durante a partida. Ainda, é possível ajustar a sensibilidade das peças, ante dispositivo contido no DGT.

Segundo conta um enxadrista da época:

"1968 em Campinas contra a equipe da casa, que contratou um Mestre Uruguaio para enfrentar o Pacini, depois da vitória do Pacini e de Itararé ele foi entrevistado onde fizeram a seguinte pergunta: “Sr. Pacini como conseguiu vencer um mestre como o Uruguaio que possui vários títulos e venceu recentemente um torneio em seu país de origem ?”

Resposta: Ninguém me falou que ele era tudo isso."

Um final de difícil arremate, seja pela pressão do tempo ou pelo stress como queiram, mas Judit com calma, aparentemente por óbvio, conseguiu vislumbrar a linha ganhadora após sucessivas inda e vindas.

O primeiro desta série foi lançado em 1980, mas não levava título "Champion". Momento seguinte, pelo que tenho notícias, foi incorporado o programa que ganhou o primeiro campeonato mundial em londres, 1980. Assim, existem duas versões, sem contar outras que dobram o processamento original de 2MHz. O fato é que estas máquinas ainda funcionam e guardadas como sucatas. Depois da pequena reforma, figuram como novos. Há quem diga que de 1983/86, foi os anos dourados para estas máquinas.

Aprendendo com os computadores de xadrez

2011-08-24T05:12:00.002-03:00

Uma das vantagens, dentre muitas, jogando com os micros dedicados ou xadrez eletrônico, como queiram, reside no fato de aproveitar o máximo das vantagem que eles proprocionam. Uma das vantagens consiste em treinar as aberturas, visto que alguns destes micros possuem uma biblioteca considerável e muito embora fabricados na década de 80/90, ainda há linhas jogáveis. Ao invés de ficar estudando linhas teóricas, há muitas delas no youtube e demais websites construídos especificamente para este fim, com os micros dedicados o aprendizado se torna mais agradável. O exemplo que se segue consiste na abertura D20: Queen's Gambit Accepted: 3 e3 and e4 (gambito da dama aceito). Particularmente eu procuro analisar as partidas com banco de dados da chessbase, e não raro vejo que as linhas proporcionadas pelos dedicados ainda se mostram atuais.

Downsizing - Outsourcing - Fidelity Electronics

2011-08-15T02:11:00.011-03:00

Em uma primeira análise, vendo as fotos da fábrica da Fidelity, pode-se observar, salvo melhor compreensão, que se consistia em uma organização verticalizada. Este tipo de organização foi predominante no século passado, década de 70/80, quando as grandes entidades praticamente produziam tudo o que usavam nos produtos finais. Pode-se imaginar o tamanho dessa organização e de sua folha de pagamento. Estas empresas na forma como eram organizadas, impunham condições ao mercado. Posteriormente, começaram a sentir-se ameaçadas pelas pequenas e médias empresas e as que sobreviveram, foram obrigadas a repensar seus procedimentos internos. Talvez esse fator, aliado a ausência de pensamento estratégico, tenha sido a causa da quebra da Fidelity Electronics. Obviamente, a Fidelity não fabricava apenas xadrez eletrônico, pois sabe-se que tinha um departamento destinado a produtos destinados a medicina, tais como aparelhos de audição. (continuo)

Para fins acadêmicos, estou procurando as demonstrações financeiras da Fidelity.

Daí o surgimento do "Downsizing", ou seja, redução de níveis hierárquicos, enxugamento de organograma e diminuição de cargos. Em decorrência deste processo, surgiu também o "Outsourcing" conhecido no Brasil como terceirização, que aprimorou a nova estratégia do mercado mundial. Pretendo abordar este assunto em postagens futuras, pois acredito que este fato tenha concorrido com a quebra da Fidelity Electronics.

Ainda tenho dificuldades sobre as possíveis conexões com Super Expert, Novag Diamond, Renaissance, etc. O software desenvolvido por Alain Zanchetta promete conexões com diversos computadores dedicados, mas por alguma razão, talvez pelo dispositivo serial I/O que possuo conectado no meu Ipaq Dell X50V ou Ipaq HP2200, somente consegui sucesso na conexão, quando indico que estou jogando com Novag Super Vip. De qualquer forma, mesmo indicando Novag super Vip, consigo sucesso com Novag Super Expert e Universal Chess Board ao contrário com o Renaissance. Vamos esperar futuras versões para ver até onde podemos chegar com este excelente programa CEboard.

Testando a velocidade de processamento do seu computador - chess position

2011-08-10T22:36:00.009-03:00

Jogam as negras e ganham

A resolução do lance ganhador no meu micro demorou cerca de 5 minutos, isso em função de eu ter ativado a captura da tela. Mas esta posição deriva de um jogo de bychamp_II (meu nick no play chess). Na partida propriamente dita, meu computador achou o lance em 59 segundos, em função do hashtable. Dirk Dagobert disse que resolveu o problema em menos de 5 minutos, pois se trata de uma posição clássica na qual a ruptura se faz presente, claro existem algumas dicas acerca da posição, pois o bisbo das brancas é chamado de bispo ruím pois seus peões estão concentrados em casas da mesma cor. Clássica ou não clássica, f5! não é tão simples de ver. No Ipaq com a engine Toga II, ficou poderando cerca de 60 minutos e não conseguiu ver o lance ganhador, ou seja, iria fritar o processador sem resolução! Entretanto, com as máquinas atuais, com estes processadores monstros, o xadrez perde um pouco do romantismo, já que num passado recente, digamos há 10 anos, não seria tão simples assim. Hoje já se fala em "clusters" 32 processadores trabalhando em série. Resumo da ópera, muito se aprimorou em meio de jogo, pouco se ganhou em novas teorias de aberturas, tanto que nas partidas entre os melhores do mundo, os lances iniciais se repetem. Por exemplo, a biblioteca do Super Expert C - máquina de 1984/85, verifiquei linhas que são usadas nos dias atuais o que vem mostrar que pouca coisa mudou.
