He couldn't figure out what its weaknesses were, or if he did, how to exploit them. Kasparov, who defeated a predecessor of Deep Blue a year ago, won the first game of this year's match, but it was his last triumph, a signal that the computer's pattern of thought had eluded him.
But I don't think this machine is unbeatable.'' Maybe it was an outstanding accomplishment by the computer. of cheating, he said: ''I have no idea what's happening behind the curtain. He added he was frustrated by I.B.M.'s resistance to allowing him to see the printouts of the computer's thought processes so he could understand how it made its decisions, and implied again that there was some untoward behavior by the Deep Blue team.Īsked if he was accusing I.B.M. ''I do not understand how the most powerful chess machine in the world could not see simple perpetual check,'' he said. Kasparov said he had missed the draw because the computer had played so brilliantly that he thought it would have obviated the possibility of the draw known as perpetual check. Kasparov had resigned what was eventually shown to be a drawn position. If it would play against, say, Grandmaster Boris Gulko, who is not even among the top 50, I am willing to bet $10,000 the computer would lose.''Īt the news conference after the game, a dark-eyed and brooding champion said that his problems began after the second game, won by Deep Blue after Mr. If they want to prove it was more than a show, let them play anyone but Garry. ''This was not a serious chess match,'' said Lev Alburt, a former United States champion who has said there are 100 grandmasters in the world who could beat Deep Blue. Kasparov's griped, apologized and vowed revenge.
Kasparov's performance at the postgame news conference, which was not the exuberant celebration envisioned by the tournament sponsor, I.B.M., but rather a tense occasion in which Mr. ''But the computer doesn't like to play in an unbalanced position,'' Mr. Kasparov was trying to capitalize on the computer's aversion to playing with a material disadvantage. ''It was a gamble,'' said Michael Khodarkovsky, a close adviser to Mr.
Having lost his queen and with his king dangerously exposed, Mr. He encouraged Deep Blue to sacrifice a knight, resulting in a position that left his own king exposed, and many chess experts wondered if he hadn't made a simple blunder. Playing black and needing a victory to capture the match, he was perhaps too defiant in the early going, pursuing a risky sequence of moves in a conservative opening called the Caro-Kann. ''I think he didn't try his best,'' said Susan Polgar, the women's world champion, who after the game issued her own challenge to I.B.M. Grandmasters at the match, at the Equitable Center in midtown Manhattan, were stunned into near-speechlessness, a feat in itself, amazed not just by the resignation but by Mr. When I see something that is well beyond my understanding, I'm afraid.'' ''I was not in the mood of playing at all,'' he said, adding that after Game 5 on Saturday, he had become so dispirited that he felt the match was already over. Kasparov, 34, retains his title, which he has held since 1985, but the loss was nonetheless unprecedented in his career he has never before lost a multigame match against an individual opponent.Īfterward, he was both bitter at what he perceived to be unfair advantages enjoyed by the computer and, in his word, ashamed of his poor performance yesterday. It was the second victory of the match for the computer - there were three draws - making the final score 3 1/2 to 2 1/2, the first time any chess champion has been beaten by a machine in a traditional match. ''It had the impact of a Greek tragedy,'' said Monty Newborn, chairman of the chess committee for the Association for Computing, which was responsible for officiating the match. Grandmasters and computer experts alike went from praising the match as a great experiment, invaluable to both science and chess (if a temporary blow to the collective ego of the human race) to smacking their foreheads in amazement at the champion's abrupt crumpling. The manner of the conclusion overshadowed the debate over the meaning of the computer's success. Kasparov had been able to summon the wherewithal to match Deep Blue gambit for gambit. The unexpectedly swift denouement to the bitterly fought contest came as a surprise, because until yesterday Mr. computer Deep Blue unseated humanity, at least temporarily, as the finest chess playing entity on the planet yesterday, when Garry Kasparov, the world chess champion, resigned the sixth and final game of the match after just 19 moves, saying, ''I lost my fighting spirit.''
