Botvinnik

He won or shared 12 Yugoslavian national titles, played in 15 Olympiads, won a slew of major tournaments, and defeated a string of world champions over the board, including Max Euwe, Mikhail Botvinnik, Vasily Smyslov, Mikhail Tal, Tigran Petrosian and Bobby Fischer.

Mikhail Botvinnik, former world champion, studied computers in the ’50s and ’60s, and even back then saw the importance of the machines.

He drew against the ex-world champion Mikhail Botvinnik during the annual tournament held over Christmas and New Year’s in Hastings, England, in 1966-67, and against Mikhail Tal, another ex-champion, during the 1973-74 Hastings competition.

Her Round 5 win over WFM Sophie Morris-Suzuki smoothly transformed the positional advantage out of a Botvinnik English into a killer attack.

When Mikhail Botvinnik, who became World Chess Champion, arrived at the Bolshoi Opera House, he was given a standing ovation.
