Kasparov x Turbostar 432

A referencia que possuo deste jogo reside em uma simultânea de Kasparov com o s computadores de xadrez  ante uma reportagem da Chessbase.

Em 6 de junho de 1985, Garry Kasparov, de 22 anos, chegou a Hamburgo para fazer uma partida de preparação para a candidatura ao Campeonato do Mundo - e fazer uma entrevista extremamente crítica com uma importante revista de notícias alemã. Durante a visita, ele jogou uma simultânea contra 32 computadores de xadrez, talvez os  mais fortes à época.

Disse kasparov:

“Em algum momento, eu percebi que estava com problemas em um jogo contra um dos modelos de marca "Kasparov". Se esta máquina marcasse uma vitória ou até um empate, as pessoas seriam rápidas em dizer que eu joguei para promover a empresa, então eu tive que intensificar meus esforços. Eventualmente, encontrei uma maneira de "blefar" a máquina com um sacrifício duvidoso que qualquer computador de xadrez moderno poderia refutar em uma fração de segundo.”

As you can see in the diagram the black knights are menacingly placed. After a passive move like Re2, the position would have been unpleasant but only slightly worse for White. Instead I decided to throw the machine off balance and sacrifice an exchange, which was objectively terrible but "psychologically" brilliant. At the time, it was understood by any strong player with experience versus computers that their main weakness was... tactics! In particular, combinations more than a few moves deep or involving pawn promotion, as the case here.} 32. Ra2 $2 {A terrible move, but not an oversight!} (32.

I could still capture on d7 hoping it would blunder and take the rook with check instead of taking the bishop.}) 38. Bxd7 Qxd1+ 39. Kh2 {The mate on g7 is impossible to defend.} Rf7 40.

Qhxg7 { A slightly embarrassing escape for me, I admit, but one that nevertheless serves as an educational time capsule of the state of computer chess at the time. Despite this swindle and a few other weak computer efforts, I wouldn't want to diminish my own play entirely. Looking at all the games again, the computers rarely blundered and it required energy and precision to make a clean score against them on so many boards even 30 years ago.} 1-0
