Chess champion Garry Kasparov will square off against DeepJunior on October 1, a computer that has not lost to a human opponent in the last two years. The match is being billed as the greatest demonstration of artificial intelligence and man vs. machine to date. Kasparov defeated IBM’s Deep Blue supercomputer in 1996 but lost to an upgraded version in 1997. “For the first time in history the King of human chess is challenged by a program that is available for any chess fan to run on their PC. The advances made in recent years by the Junior programmers are truly remarkable and I expect the match to be a very close contest,” David Levy, President of the International Computer Games Association, said in a statement.
