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.''
