Brains in Bahrain
Brains in Bahrain was an eight-game chess match between World Chess Champion Vladimir Kramnik and the computer program Deep Fritz 7, held in October 2002. The match ended in a tie 4-4, with two wins for each participant and four draws.
==Outcome of games==
The first game was drawn. Kramnik won games 2 and 3 by "conventional" anti-computer tactics—play conservatively for a long-term advantage the computer is not able to see in its game tree search. After a draw in game 4, Kramnik lost game 5 due to a blunder. Game 6 was described by commentators as "spectacular". Kramnik, in a better position in the early middlegame, sacrificed a piece to launch an attack—a strategy known to be highly risky against computers, which are at their strongest when defending such attacks. True to form, Fritz found a watertight defense and Kramnik was left in a bad position. Kramnik resigned the game, believing his position to be lost. However, post-game analysis has shown that Fritz was unlikely to have been able to force a win—Kramnik gave up a drawn position.〔(Analysis of Game 6 ), by Mig Greengard, Chessbase〕 The final two games were draws.〔(Fritz Defends to Draw Game 8 and the Match! Final Score: 4-4 ), Chessbase, 19 October 2002〕
