Fidelity Designer 2100 x Novag Constellation Expert

Dois computadores, programadores distintos, mas contendo o mesmo rating. Na partida que segue, optaram por siciliana, linha amplamente conhecida. Com d5, novag sai da da abertura.

Notar que o programa chessbase, indica a precisão dos lances, neste caso para as brancas 57% e as pretas 26% o que convenhamos é muito pouco para computadores de xadrez.

Mephisto MMV - 18 MHz

Alguns anos atrás, um técnico alemão ou colecionista, não saberia dizer sua atividade principal, desenvolveu para o Mephisto MMV, um sistema que possibilitava o módulo processar em 18 MHz.
O módulo é o mesmo que o primitivo, apenas algumas mudanças em relação as memórias e a mudança da voltagem, quando comparado com o módulo primitivo.

Como de praxe, este módulo esteve em minhas mãos no passado e alguns meses depois, troquei com um colecionador no Brasil.

Como de costume, recentemente o módulo voltou para minha coleção. Desta feita, para certificar a verdadeira força em relação ao módulo primitivo, procedi algumas partidas entre o 18 MHz e o módulo normal. Foram 3 partidas, todas com vitória para o 18 MHz.

Apenas o primeiro jogo o MMV versão original ofereceu resistência ao 18 MHz, sendo que as demais consistiram em verdadeiro massacre. Portanto, 18 MHz, fez jus a fama na época. Infelizmente este colecionador ou técnico não mais disponibiliza este módulo.

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.”

Chess Size Guide by regencychess


Impossível não seguir as regras com relação a proporção das peças. Tenho insistido muito nisso, mas os absurdos são constantes. Este torneio estão jogando os melhores, mas as peças, vide o Rei, totalmente sem proporção. Este fato fica mais visível quando comparamos as peças dos dedicados.
