Second Victory against Kramnik in the Last Match - Deep Fritz

In the sixth and final game of World Chess Challenge, chess computer Deep Fritz(Germany - white) held onto its lead against Vladimir Kramnik (Russia - black), and even notched up a second win against the World Champion. That means the world's leading chess computer is the ultimate winner of the Man vs. Machine duel. Four draws and two wins for Deep Fritz - that's the legacy of World Chess Challenge, which excited fans all over the world have been following closely since November 25.

After more than four-and-a-half hours and 47 moves, Vladimir Kramnik accepted the defeat against his opponent - an opponent whose computational abilities are almost unfathomable: Deep Fritz calculated eight to ten million positions a second during World Chess Challenge. The audience at the Federal Art Hall in Bonn responded to today's epic battle between human and artificial intelligence with applause. The World Chess Challenge Cup was then handed over to the Deep Fritz team in a presentation ceremony.

Deep Fritz opened with 1.e4, while Kramnik opted for the Najdorf Variation of the Sicilian Defense. A risky move - but one that held out the promise of a win. The players then engaged in a sophisticated open middle game with opportunities for development on either side. A sudden attack by Deep Fritz gave the machine an advantage in material; Kramnik began playing with one pawn less in the 30th move. During the end game, Kramnik had no way to save himself from defeat.
