CLEVELAND, Feb. 16 /PRNewswire/ -- Ever since chess champion Garry Kasparov lost to Deep Blue in 1997, humans have not been able to regain a victory against computers in an official Man vs. Machine match. All recent chess matches between the top human players and top-ranked computer programs have ended in draws. However on February 13th, humans reclaimed their dominance over the chess board when the world's best Arimaa-playing program was defeated 8-0 by a top-rated Arimaa player, Omar Syed.

In 1999, Garry Kasparov agreed to play a game of chess, via the Internet, against the rest of the world in consultation, with the World Team moves to be decided by majority vote. The host and promoter of the match was the MSN Gaming Zone. After 62 moves in 4 months Kasparov won the game.

In 1996 Kasparov competed against an International Business Machines (IBM) computer named Deep Blue, the first time a world champion had competed against a computer under standard match conditions. Deep Blue, operated by a team of IBM programmers, was capable of processing millions of chess positions per second. Applying this massive computational power, a technique of artificial intelligence known as brute force, Deep Blue won the first game of the match to become the first computer to defeat a world champion under regulation time controls. Kasparov subsequently defeated Deep Blue by a score of 4 games to 2 to win the match. A year later... Kasparov accepted a rematch against an enhanced version of Deep Blue, capable of processing 200 million chess positions per second. Although Kasparov won the first game, he was defeated in the six-game series 3.5 games to 2.5 games.

Kasparov has found his toughest challenge in the five matches with Karpov for the world championship which he contested from 1984 through 1990. The first match with Karpov was held at Moscow 1984-5. The winner was to be the first player to win six games. It looked like Karpov had it sewed up after nine games with the score at +0=5-4, but a long series of draws ensued and Kasparov rallied (+3=40-5). At this point, Karpov apparently called FIDE president Florencio Campomanes who declared the match aborted with no result. In the rematch at Moscow 1985, Kasparov beat Karpov to become champion (+5=16-3).

Kasparov's third move was the first real surprise of the game. He typically plays the more ambitious 3.d4 in this position, immediately opening the game. His actual move is more likely to result in a closed game with only a strategic pull for White. Kasparov apologized to the World Team for this move, but excused himself in light of his upcoming match for the World Championship against Vladimir Kramnik in 2000. Presumably he had prepared some innovations in his main lines, and didn't want to reveal them in advance.
