Man verses Machine - Round 2 New York City is gearing up for an unprecedented clash between intellectual heavyweights: Grandmaster Garry Kasparov will take on reigning World Computer Chess champion Deep Junior, beginning on Sunday. Kasparov is hoping to make up for his widely publicized 1997 defeat at the keyboard of IBM's chess supercomputer Deep Blue. This time he has been able to practise on a version of Deep Junior - which any buff can run on their laptop - for several months. Go to chessbase to replay game one - one up for the carbon side.
