　　In 1997, Garry Kasparov, the Russian grandmaster of chess (棋) who was then the world champion (冠军), played a match against the I. B. M. supercomputer Deep Blue. Mr. Kasparov lost the six - game match by a single game. Now almost six years later, Mr. Kasparov begins a match against an Israeli program, Deep Junior, the three - time world computer chess champion. The match will be played at the New York Athletic Club, and shown in real time on the Web at www. x3dworld. com. The play will start at 3:30 p. m. on Jan. 26, 28, and 30, and on Feb. 2, 5, and 7.

　　As early as 1957, Herbert A. Simon predicted (预言) that a machine would become the world chess champion in ten years. A game of chess is considered a calculation (计算), and calculation, of course, is what computers are good at The situation today is that both humans and machines can play world - class chess, but they do completely differently. Deep Junior examines three million positions per second. But even at that speed, it cannot generally see that far ahead. That is because the number of possible chess positions is staggering. There are some 85 billion ways of playing just the first four moves for each side. The strength of worldclass human players lies in their ability to decide who stands better in a given position, and that ability is hard to build into a machine. Mr. Kasparov admits that he examines only one to three moves a second, but he is not sure that they are the strongest ones.

　　Although Deep Junior is much slower than the I. B. M. computer, experts said it had more chess knowledge built into it. It clearly considers more elements in judging a position. “Junior is very humanlike,” Mr. Kasparov said. “It's a computer version (转变) of me. It plays forcefully, imaginatively and takes risks. The match will be close, but I'm determined to win. One thing I know is that humans' days at the top of the chess world are limited. I give us just a few years.”
