World chess champion Vladimir Kramnik will play the Deep Fritz 7 chess supercomputer in an eight-game match in Bahrain in October, organizers Brain Games announced yesterday.

This will be the first man versus machine chess showdown since IBM's Deep Blue RS/6000-based parallel computer defeated former world chess champion Garry Kasparov 3.5 points to 2.5 points in 1997. The match has been given the title "Brains in Bahrain". Kramnik, a Russian, will earn $1 million if he wins, $800,000 for a drawn match, and $600,000 if he loses.

Kramnik ended Kasparov's 15-year reign as world champion last year, and will be playing against a machine capable of analyzing 4 million moves per second.

Deep Fritz has been built from scratch by an independent group of computer and chess specialists, led by Dutch programmer Frans Morsch, after IBM decided not to continue the Deep Blue project. Deep Fritz has previously beaten Deep Blue, Kasparov and World Chess Federation champion Vishwanathan Anand.

The 1997 match offered evidence that machines could be more effective in carrying out some complex processing tasks than humans, re-igniting a long-standing debate about machine, or artificial, intelligence.

Brains in Bahrain will be played between October 14 and October 31.
