Commentary for white move 7: DB MOVE: 6...00.

MAURICE ASHLEY: -- do you think the computer knew more than he knew? A human would have played that against a human sort of as a last shot. Maybe the Kasparov -- Deep Blue has just castled and Kasparov has quickly responded -- GK MOVE: 7 G B -- Bg2.

MIKE VALVO: Why didn't Deep Blue just win by playing Qb6 at some point rather than Be4? And Garry is thinking, why didn't it do that? He's been losing the /HO*ELD whole game in his own mind, depressed, frustrated, and said oh, God you're going to win a piece, I've had it, and he tosses in the towel.

MAURICE ASHLEY: What have you seen over the years -- you've been doing this since 1970, being an arbiter at computer tournaments. What have you seen over the years with men's reaction to the computer when they start realizing they can actually lose to this thing?

MIKE VALVO: Well, this terms -- in terms of playing the early-year computers, you never resigned. In those days they made illegal moves. Actually I was arbiting a game one time when a guy was making a queen, except it didn't know how to promote, so it just left the pawn on the eighth rank. (Audience laughter.)

MAURICE ASHLEY: We've moved on since then.

MIKE VALVO: We've moved on since then. But in the early years of the predecessor of Deep Thought, there was a machine called Chip Test, the original version. When Feng Hsu first came out, it made an illegal move, I was called over, and I said that's an illegal move according to the rules of chess you have to take the move back and make a legal move. So they took the move back and Chip Test said oh, that was an illegal move I just made and made a legal move, and the game went on. Till ten minutes later the same thing happened. But the game went on. Now, I don't understand that, because computers tend to do the same things over and over given the same circumstances but somehow it made a different move. Why it made an illegal move, I don't know. But we've come a long way, baby, since then, I must say.

MAURICE ASHLEY: The question I'm asking, though, what about the humans? What about how the humans have responded? Have you seen a change in the atmosphere of humans when they play against computers?
