''So it's not the 200 million positions per second,'' Mr. But a handful of moves, maybe 1 percent, Fritz could never duplicate at all, even after Mr. Most of the other 20 percent were duplicated after letting Fritz search for six or eight hours. Kasparov's computer adviser, said their own computer, Fritz - capable of sophisticated evaluation but 1,000 times less powerful than Deep Blue - duplicated 80 percent of Deep Blue's moves during the match within a minute or so of analysis. Hoane said, when asked whether he was inclined to go at Mr. ''There are a lot of great chess players,'' Mr. Kasparov's intimations, would not commit themselves to a third match. The Deep Blue team, clearly offended by Mr. I have to imagine human interference, or I want to see an explanation.'' People turn to religion to explain things like that. Tell us how you accomplished it, because it's far beyond anyone's understanding. ''If that is the case,'' he said, ''then they have to explain it to the rest of the world. The Deep Blue team agreed that this was the main element in the computer's improvement (though the extra speed didn't hurt), but it is something Mr. It seemed, he said, to understand complexities of chess that no other computer has come close to duplicating. It was its ability to evaluate those positions. Kasparov is his sense that it was not Deep Blue's awesome calculating ability - it can examine 200 million moves per second - that defeated him. But I don't know what the computer did wrong or right. ''It's very difficult to analyze the results of the match,'' Mr. During the match, he attributed one move to ''the hand of God.'' In an interview on Friday, in which he challenged Deep Blue to a third match, the word he used was mystery. Kasparov expressed his frustration again and again in terms that had to do with the machine's magic. The match ended in an atmosphere of hostility and suspicion, and Mr. Unlike the queen, most of them are really there. Deep Blue sees things, at least on occasion, that no other machine, or human, can see. The image of a magically appearing queen nicely represents the accomplishments of Deep Blue, which a week ago made history by whipping Mr.
It took two weeks to adjust the software and fix the bug, the mention of which still sends the chip designer, Feng Hsiung Hsu, into a fit of guilt. The culprit, it turned out, was a newly designed chip linking Deep Blue's powerful multiprocessors with its chess software. But in February, there was this invisible queen.
