Man and computer in chess cliff-hanger The man-versus-machine chess duel is set for a dramatic finish on Saturday with world champion Vladimir Kramnik of Russia and the computer Deep Fritz tied 3.5-3.5 after seven games. Kramnik, 27, offered a draw after his 28th move on Thursday at the tournament at Manama in the Gulf state of Bahrain. Deep Fritz, a German-developed computer, can evaluate 3.5 million moves per second. But Kramnik was allowed to practise against it for two weeks before the contest. The match is a sequel to the 1997 contest in which Deep Blue, an IBM computer, defeated then world champion Gary Kasparov. If he wins Saturday's decider, Kramnik will get $1m, while a draw will earn him $700,000 and a defeat $500,000.
