BONN, Germany – World chess champion Vladimir Kramnik lost the sixth and decisive game against computer program Deep Fritz on Tuesday, ceding a hard-fought Man vs. Machine match 4-2.
The Russian takes $500,000 — 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.
Kramnik said he was "a bit disappointed" and expressed hope that a rematch could be arranged in a year or two. "With more time to prepare, I still have a chance."
With a computer that calculates millions of positions every second, "there are always certain threats," Kramnik said.
In October, Kramnik defeated Veselin Topalov of Bulgaria, becoming the first universally recognized world chess champion since 1993.
