Deep Fritz checkmates Kramnik

Deep Fritz, a chess-playing computer, has beaten human counterpart world chess champion Vladimir Kramnik in a six-game battle in Bonn, Germany.

World chess champion Vladimir Kramnik lost his final game in a match against computer program Deep Fritz on Tuesday, ceding a hard-fought Man vs. Machine series 4-2.

Kramnik, seeking a final win to level the match, played an unbalanced opening with Black. He built up a good position and equalized. But he then went astray, losing a pawn from which he never recovered.

The Russian takes home $500,000 (euro375,000) half of what he would have received if he had won against Deep Fritz, a commercially available chess program that runs on a powerful personal computer.
