Commentary for black move 8:

Now, let's go back to the position at hand, that is to say, what Deep Blue is thinking about. Garry has another alternative. He could play after dxe4, we have a new variation. Garry could trade queens. Now, one of the things that we've seen in this match, and especially in game four, Garry had all of his attacking potential that he sought to exchange queens, even when he had this possibility of Qc7 going for the attack. So Garry may embrace the ending d5xe4 d3xe4 Qxd1+ Kxd1 O O+ and -- O O O+ and Ke2. In the endgame the king on e2 will be a good piece. This is what Deep Blue and Garry are probably looking at.

DB MOVE: 8...didxe4.

MAURICE ASHLEY: What we had anticipated has occurred. The exchange dxe4 has occurred, and Kasparov has his first big decision of the chess game, and the whole character of the game is about to change. Kasparov is bouncing in his chair, and he knows it's time to decide. If he plays Bg2 -- takes Bg2, he keeps queens on. Maybe he'll exchange queens, thinking it's best to play Deep Blue that way, play an endgame where computers have been known, Mike, to not be so good?

MIKE VALVO: Yeah, it's an area where computers are probably at their worst, the endgame. They would be even worse off in the opening except that the openings are programmed into them from the start, so they usually don't wake up until about move 10 or 15 unless they're playing Garry, then they wake up about move three or four.

MAURICE ASHLEY: Good point. And still Kasparov is thinking about this position, despite the fact that we've been eager, I mean eager, like a man from a mission, the moment he sees the opportunity to exchange queens, has done so in the blink of an eye. But here for some reason, he's really hesitant, and maybe he's not so confident after that position after the exchange of queens, Yaz.
