Deep Fritz, the world's leading chess computer, on Wednesday roundly beat its human counterpart, the Russian world chess champion Vladimir Kramnik, in a six-game encounter.
Deep Fritz won by four points to two, after taking the last game in 47 moves in an epic battle lasting almost five hours.
Of the six games, Deep Fritz won two and four ended in draws.
The 31-yeard old Kramnik, who received $500,000 dollars for playing the mighty machine, could have walked away with double that sum if he had won. But the world champion had acknowledged even before the opening moves that Deep Fritz was "the clear favourite".
In October 2002, Kramnik had held Deep Fritz to a draw after eight games, but the chess software has since been updated, becoming vastly more powerful.
