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.”

Instead I decided to throw the machine off balance and sacrifice an exchange, which was objectively terrible but "psychologically" brilliant.
