Garry Kasparov

Trago aos leitores do meu blog, uma postagem publicada no meu canal do youtube "bychamp", no qual um seguidor informou o verdadeiro nome de Garry Kasparov. Com efeito, não tenho como atestar a veracidade das informações, todavia entendo relevante reproduzir o texto, tal como fora postado:

"Garry is Jewish-Armenian. His real name is GARRY KIMOVICH WEINSTEIN, and after his father's death, he started to use more and more publicly his mother's surname KASPARIAN... The Soviets have changed his name for KASPAROV because it sounded more Russian. Best regards from Israel to all Armenian nation around the world, specially today when we all remember your 1915 victims killed by the Turks. Armenia is a great nation!"

Aulas - Carlos Alejandro Martinez, e4 como ruptura!

Interessante ler a matéria em chessbase.com, Natalia Pogonina and Peter Zhdanov, the new chess couple 

"Could you tell un about your new project "Chess Kamasutra", a very subject for a chess book."

"Both chess and the Kamasutra originate from India. In “Chess Kamasutra” I and my co-author Peter Zhdanov will show that it is possible to apply sex principles to chess, and vice versa. We will be reviewing the most interesting openings and middlegame positions, and relating them to positions from Kamasutra. We surprise our readers by introducing the “love theory”, which is extremely effective for developing your chess skills and becoming happy in personal life. We will share unique training methods in “sexchess”, approbated by ourselves. Chess Kamasutra is going to be a very entertaining and useful book covering many interesting subjects – we aren’t revealing most of the secrets yet, but one day you’ll be able to see it for yourself."

Uma partida contra MMIV

Arena se constitui em uma interface que possibilita a conexão com Novag Citrine. Assim, ao invés de jogar contra a engine nativa do Citrine, pode-se escolher com qual engine jogar, dentre as centenas delas disponíveis. Desta feita joguei contra a engine MMIV. Todavia Arena tem um bug quando conectada ao Citrine, ou seja, não consegue parametrizar o tempo adequadamente. Inobstante já ter comunicado este fato, até o momento não temos uma nova versão corrigindo este erro. 

Entretanto, com bug ou sem bug, não consegui ganhar esta partida, embora tive amplas possibilidades de arrematar.

ChessTV,  transmitindo 24 horas, programação exclusivamente destinado a  eventos do xadrez, não tem tradução/interprete para o Ingles, ou seja, a quem se destinaria essa programação? Para quem se prestaria essa programação? Que linguagem estranha e confusa! Claro que representa um avanço, mas o mundo deverá ser curvar e aprender russo para entender o que eles falam.

ChessTV 12:0, broadcasting program exclusively for Chess events, has no translation for English, that is, for who is this program? This strange and confusing language!

Além de trazer as engines Fruit em todas as versões e Toga, o program incorpora as seguintes engines:

Viper

Viper is a simplified and considerably weaker version of the chess engine Glaurung. It's main purpose is to serve as a simple instructional example for beginning chess programmers who want to write a parallel search.

At the moment, Viper is still bigger and more complicated than I would like, weighing in at 4924 lines of code. I intend to continue to make it smaller and simpler, while adding more comments.

Glaurung is a strong free chess program for the Apple iPhone. It's powered by the Stockfish chess engine by Marco Costalba, Joona Kiiski and Tord Romstad, one of the strongest free chess programs.

GreKo,

a Chess Engine Communication Protocol compliant open source engine by Vladimir Medvedev, written in C++ and relying on the Standard Template Library. Starting the development in 2002, GreKo was first a classical alpha-beta searcher within an iterative deepening framework, performing an evaluation considering material and various positional aspects such as pawn structure. Checks, recaptures and passers arriving the seventh rank were extended. The opening book utilizes the hash table to recognize transpositions.

Phalanx's playing style is quite human-like; when it plays at full strength, it may be compared to a intermediate-to-strong club player; beginners will be right at home with it, too. I made some very little changes on Dobes's latest version of Phalanx so it could compile and run on any modern GNU/Linux system. The GCC compiler is required, as it uses some of its extensions. I plan to change that. You can download, report bugs, and discuss Phalanx on the Project page, or make any requests to me directly, espinafre at users dot sourceforge dot net.

"Chessbase.com, May 28th, 2000

PhalanxXXII was the most interesting of the seven engines (in my opinion). I was looking forward to a wild sacrificial game against it (based on the engine's description at the ChessBase GmbH site), but Phalanx fooled me. I played a couple of games against it immediately after replaying a couple of Steinitz' games from Reti's book Masters of the Chessboard. Steinitz was the master of the pawn push. He often drove his pawns relentlessly forward to deny space to his opponent. To my surprise (I might even say "shock"), Phalanx does the same thing. Control of space is evidently given high priority in its evaluation algorithm. As I played against Phalanx, it seemed intent on throttling me ("python-like", to use the hoary old stereotype). I give this program high marks for positional play -- the pawn pushes it made were all strong ones, and it never gave my Knights a chance to exploit any holes it may have created. Despite the relatively low rating range in "Handicap and fun" mode (1150-1950), Phalanx was without question the most unique and interesting of the seven engines and I'm looking forward to my next game against it."

Scorpio,

a sophisticated open source chess engine by Daniel Shawul, written in C++ and compliant to the Chess Engine Communication Protocol with builds running under Windows and Linux. Scorpio participated at the CCT9, CCT11 and CCT12 online tournaments, and played the ICT 2007 over the board. It is base of Daniel's general game playing engine Nebiyu, able to play Chess variants, Checkers, Reversi, Go and Amazons.

Oswaldo Monteiro x Super Expert C - 15 minutos - total game

Os ensinamentos do Martinez, quando está presente, parece de uma simplicidade sem precedentes, mas na sua ausência, "a coisa pega". Aliás, não me prendo aos ensinamentos do Martinez, me dou bem com todos, Dirk, Cícero, todos mestres e com conhecimentos estratégicos de alto nível. Cada qual com seu estilo, Dirk, agressivo, Cícero, me parece posicional, Martinez, tático, merece ser ouvido, seus golpes tem uma visão invejável. No entanto, nesta partida, embora jogando com atenção, perdi no tempo e posteriormente, com a engine verifiquei que a disputa estaria aberta, para ambos os lados.

Using Heuristic-Search Based Engines for Estimating Human Skill at Chess (by Matej Guid; Ivan Bratko; Ljubljana, Slovenia)

Using Heuristic-Search Based Engines for Estimating Human Skill at Chess (by Matej Guid; Ivan Bratko; Ljubljana, Slovenia) 

Interessante o presente trabalho, o qual trata das diferenças quanto a avaliação das posições proporcionadas por diferentes engines. O trabalho é abrangente, todavia dentre as diversas considerações apresentadas, destaco a seguinte:

"Capablanca-Alekhine, World Chess Championship match (game 27, position after Black’s 37th move), Buenos Aires 1927. White is winning after 38. Kf1-e2!,

for example: 38. ... Qc1xb2+ 39. Ke2-f3 Qb2-b3+ (or 39. Qb2-c3+ 40. Kf3-g4!) 40. Kf3-f2! and the white King safely returns to h2, avoiding any further checks. However, Capablanca played 38. Kf1-f2?? and after 38. ...  Qc1-d2+! had to agree to a draw, since there is no escape from perpetual check now. How much should White be “punished” for his mistake? The table on the right shows backed-up heuristic evaluations obtained by various chess programs, when evaluating the moves 38. Kf1-e2 (computer’s choice) and 57. Kf1-f2 (move played) using 12-ply search. While all engines agree that the position is equal after 38. Kf1-f2, there are vast differences among the evaluations of 38. Kf1-e2."

"Vladimir Kramnik - Chess openings are like science"

"Chess openings are like science. It keeps evolving. Judging by the standards of the time when Garry was an active player, he indeed knew the opening extremely well. Now it is over, his preparation isn’t good anymore. It is part of the past. Chess is developing very rapidly – just like the Internet, gadgets. You know, no one cares about the first models of iPhones now. Without day-by-day opening studies it is not possible. You can’t just invent a bunch of ideas and then spend ten years capitalizing on them. In the 70s or 80s this might have been possible. Now, in the computer age, you have to keep finding more and more new ideas. This is a paramount amount of work. You can’t rely on the old databases. I can see that Anand and his team are constantly working on his openings and refreshing his repertoire. I mean not cosmetic changes, but entirely new approaches. This hard work builds up over the years and offers its own benefits. Hence, I think that it will be very hard for Magnus to catch up, because even if he starts working 24/7, then in just half a year he still won’t be able to build up as much opening muscles as Anand has established over the past decade. He might come up with something sly though. Remember, when I played a match against Kasparov, I realized that he will be prepared better in the opening than myself, but I managed to present a new word in opening theory and somehow level our chances in the opening."

Há anos tenho enfatizado que o repertório de abertura representa algo em torno de 60%, tanto para os torneios e partidas entre máquinas como também para humanos. Martinez disse que estes mestres tem enfrentado aberturas complexas, requerendo estudo de altíssimo nível, portanto com extrema felicidade os dizeres de Kramnik. Em se tratando de máquinas, talvez o único fabricante que enfrentou na década de 80/90 o tema de aberturas foi a Fidelity, trazendo para seus computadores, módulos de abertura, que atualmente está sendo recapitulado por um engenheiro inglês,  disponibilizando módulos para as máquinas da Fidelity.

Aos poucos vou evoluindo, e existem dias que me sinto melhor, cometendo menos erros. Por certo, xadrez é um eterno aprendizado  e as máquinas ensinam também. É bem verdade, que eu somente jogo partidas rápidas, de 3 minutos, o que aumenta significativamente a possibilidade de cometer erros. Mas para aqueles que pensam em sentido contrário, partidas em 3 minutos é hábito, estimulando o pensamento rápido. No mínimo é divertido. Um detalhe importante: De todos os métodos que já experimentei para o aprimoramento do xadrez, leituras, máquinas, vídeos, o que se mostrou mais eficaz foi a construção livro de aberturas e concomitantemente, ver as partidas que o Martinez tem jogado no playchess, (chessbase), por diversos anos. A grande vantagem, ao contrário de aulas específicas, prende-se no fato que Martinez comenta do início ao fim, cada lance que efetua. Convenhamos, em partidas de 3 minutos, não é fácil comentar e jogar ao mesmo tempo. Martinez consegue administrar este tempo. Aquele velho ditado aplicado em finanças, administração vale para o xadrez: "é preciso ser eficaz, não basta ser eficiente". Cada caso é um caso, e não se pode generalizar. Aulas em grupo, não raro, mais confundem do que elucidam, porque cada aluno tem deficiências específicas e o esforço do professor não se concretiza. (Oswaldo Monteiro)

Segue a partida eu jogando com as pretas.

The last round - great luck to Carlsen

As últimas partidas de Carlsen, neste torneio, demonstraram comportamento diverso daquele que estamos acostumados a ver. Talvez cansado, e quem sabe uma ausência de preparo psicológico para aguentar a estrutura de um torneio desta magnitude.

I recognize that the latest matches of this tournament, Carlsen showed different behavior from those that we are used to seeing. nerves, perhaps tired, and maybe a lack of psychological preparation to hold the tournament structure.
