943 — Man vs. machine: Kasparov trounces computer foe

Nov 19, 2003 | Conteúdos Em Ingles

Chess great Garry Kasparov on Sunday virtually shut down computer program X3D Fritz to score a vital win in the third game of his latest man vs. machine match. World No. 1 Kasparov, 40, had a winning position with the white pieces after only 16 moves and coasted until the computer’s programmers resigned on its 45th turn after more than four hours of play. Kasparov is playing without physically moving pieces on a board. The Azerbaijan-born grandmaster sits in front of a monitor wearing black 3-D glasses that make the image of the board appear to float in front of him. He announces his moves into a voice-recognition software.

In the early stages, Kasparov seized a black pawn and built a wall of pawns that restricted his opponent to ineffective moves that were ridiculed as ‘silly’ by chess experts at the New York Athletic Club venue.

The grandmaster’s victory was what he needed to stay in contention in the four-game match. The first game was drawn Nov. 11 and the computer won the second game on Thursday after Kasparov blundered.

The match was tied at one and a half points each. One point is given for a win and a half point for draws. The fourth and final game was scheduled for Tuesday with the winner to collect €168,000.

German-built Fritz plays as well as a strong grandmaster, but chess programs generally do not perform well in closed positions because they cannot calculate ahead as clearly as they can in open, tactical battles.

X3D Fritz is a combination of Fritz software that is sold commercially and the New York-based X3D Technologies company’s virtual reality software.

The contest is the latest in Kasparov’s quest to outsmart computers at the ancient game. He defeated IBM supercomputer Deep Blue in 1996, lost famously to an improved Deep Blue in 1997 and in Feb. 2003, tied with Israeli-built world chess computer champion Deep Junior.
