Russian chess master.
He became an international grandmaster following his victory in the 1980 World Junior (under 20) Championship. In 198485 Kasparov met world champion Anatoly Karpov in a match that was aborted after five months of play; in late 1985, Kasparov won a 24-game return match 1311. The International Chess Federation (FIDE) stripped him of his title in 1993 in a conflict over the venue for a championship match, but the rest of the chess world still accepted him as champion. In 1996 Kasparov defeated IBM's custom-built chess computer Deep Blue in a match that attracted worldwide attention. In a 1997 rematch, an upgraded Deep Blue prevailed. In 2000 Kasparov lost a 16-game championship match to Vladimir Kramnik of Russia.
