Kasparov, Garry
In 1993 Kasparov broke with FIDE and formed the rival Professional Chess Association, becoming its champion. In 1996 he became the first world champion to lose to a computer in a game played with time controls, but he won the match. In 1997, however, the computer, IBM's “Deep Blue,” defeated him in a rematch (see also artificial intelligence). In 2000, Kasparov lost a match and his widely recognized status as the world's best chess master to his onetime protégé, the 25-year-old Russian Vladimir Kramnik, but he subsequently was again regarded as the world's top player. A 2003 match with the chess program “Deep Junior” ended in a tie. One of the game's greatest players, Kasparov retired from professional chess in 2005 and subsequently devoted himself to political activities related to promoting democracy in Russia; he has been assaulted and arrested several times. In 2007 he sought to run for the Russian presidency but was barred because a registered political party had not nominated him; he subsequently withdrew, suggesting that attempts to meet the alternative requirements were frustrated by government interference. Having unsuccessfully sought Latvian citizenship in 2013, he became a Croatian citizen in 2014. He and his family have lived primarily in New York City since 2005. Kasparov's book
