Game 2, black

Commentary for black move 35:

MAURICE ASHLEY: The jacket is still on. That's a good sign, that's a good sign. He hasn't taken the jacket off. The jacket off usually means I'm busted and I've got to find my way out of this situation.

MIKE VALVO: He's kind of praying now.

PATRICK WOLFF: I don't think he's praying so much as contemplating, actually. In thought.

MAURICE ASHLEY: I've got to take a different view here, guys. Garry Kasparov, as we said, shows a lot of emotion. This particular posture is not one I've seen when he's in trouble. And I think that he's figured out something -- I don't know what it is, but something that says you might win a pawn, but maybe we can take this plan to some kind of interesting endgame where you're not winning the game. And --

PATRICK WOLFF: Well, let's take a look --

MAURICE ASHLEY: He's not acting right now like a big man. I heard a fan say, "Come on, Garry, in the audience." Coming back on stage is Grandmaster

YASSER Seirawan. Mike Valvo will go on a break.

PATRICK WOLFF:

YASSER, what do you think about Qb6. Have you been analyzing this with Lubosh?

MAURICE ASHLEY: Two I will lustryous Grandmasters on stage with me, five U.S. championship between them, so they should be able to answer the question definitely. (Audience laughter.)

PATRICK WOLFF: Five U.S. championships between us, how come neither you or I are U.S. champion this year?

YASSER SEIRAWAN: I don't think either of us played. We needed to give the others a chance.

PATRICK WOLFF: I was worried you would show up.

YASSER SEIRAWAN: We think that -- I'm not using the royal "we" but Lubosh Kavalek and I, but Garry is in trouble, but he's got this very intriguing double-pawn sacrifice to try to create a mating attack. I know that sounds kind of weird. Let's take a look at it.

PATRICK WOLFF:

YASSER SEIRAWAN: What we were looking at was the move Rc8-d8, supporting the bishop, then anticipating a4xb5 --

MAURICE ASHLEY: Kasparov has left the board.

PATRICK WOLFF: Hang on. Before we play that move I should point out that white could play the move Be4 here which might stop juror idea, so let's keep that in mind.

MAURICE ASHLEY: Let's first get the idea so we know where you guys are headed.

YASSER SEIRAWAN: Okay. a4xb5, and now comes the move Ra8-b8, getting off the a-file. Qb6xa6. So that's the double-pawn sacrifice, and now just the move that Patrick wanted to shut down, that guy, e5-e4. And we'll see what Fritz thinks now.

MAURICE ASHLEY: So the main idea here is --

AUDIENCE MEMBER: Fritz likes.

YASSER SEIRAWAN: Fritz likes, uh-huh. The main idea is to create a battery on the h2 diagonal with the move Qe8-e5, and then trying to come in with Qe5-h2.

MAURICE ASHLEY: Now, Fritz is ignoring that threat as if to say it's meaningless and advancing the pawn to b6.

PATRICK WOLFF: I'd like to point something out here. The strategy that

YASSER is suggesting is a very typical strategy in these type of positions, giving up material for a mating attack. Human beings. Even

YASSER who has a profound respect tore material --

YASSER SEIRAWAN: Absolutely of.

PATRICK WOLFF: -- all human Grandmasters have learned from experience that this type of counter play is dangerous, we try to minimize it, we try to avoid these possibilities for the opponent if we see the opponent is going for it, but it is precisely this kind of thing that Garry tried to do against Deep Blue in the first game of the last match, and Deep Blue took the pawns, said, "Thank you very much," weathered the attack, and won the game. So this is exactly the sort of thing that a human might say, "No, no, no, can't allow this kind of play." But Deep Blue might just calculate it all the way to the end. We may be in for a very exciting game if something like this happens.

MAURICE ASHLEY: And probably something necessary to happen, because Kasparov is not the kind of person who likes to hunker down and just defend. And maybe it's not good enough in this kind of position where all the positional trumps are on Deep Blue's side -- the rooks, the queen penetrating into the position, the attack on b5, the light squares. There's a lot going on here, and no doubt Kasparov has seen variations just like this one and is ready to execute them. So it will get wild and woolly, and hold onto your hats, because this is going to go down to the wire.

PATRICK WOLFF: We'll take questions in just a moment. I just want to point out two things. First, I want to show you that this move, Qe5 is the idea that

YASSER was angling for, although white has a couple of extra pawns this, queen check would be very dangerous. One sample variation goes Qxc4 Qh2+ king let's say f1, and now suddenly e3. Now also all sorts of dangerous threats are happening around white's king. The second thing I would like to point out is that we can go all the way back to this moment. Remember we were suggesting white plays Qb6 and then Rd8. I do want to point out that a human who saw this position --

MAURICE ASHLEY: It has instead played axb5.

PATRICK WOLFF: My point was going to be white could block the play by playing Be4, but this is all moot because white has not played Qb6.

MAURICE ASHLEY: Well, the big question for us is why Qb6 was not played, and maybe some of the variations that you just mentioned,

YASSER, prevent the computer from going into that aggressive mating idea. Maybe it saw deep enough into the position to say "Well, we don't to want give him any of those kind of mating attacks because it will compensate. Instead it has taken on b5 which comes as a surprise to us. More of a surprise to me is the fact that it took so long to finally take on b5 after taking so long on the previous prove. Kasparov has recaptured with his pawn.

YASSER SEIRAWAN: But actually while I was getting remiked up, I'm thinking that the move axb5 is actually a very nice move. It does clarify the position, and let's take a look what Fritz thinks now of the move Qb6.

MAURICE ASHLEY: Fritz is not as impressed by this move. Fritz thinks that after Qb6 the position is just slightly advantageous to white.

PATRICK WOLFF: Yes, but I disagree with Fritz. What Fritz is saying is Qb6 --

MAURICE ASHLEY: It's actually changed its evaluation as we just spoke.

PATRICK WOLFF: Good. It should.

MAURICE ASHLEY: It now thinks that wheat has even more of an advantage with Qb6.

YASSER SEIRAWAN: After an exchange of rooks on a2.

PATRICK WOLFF: This is what it was suggesting. In this position Fritz saw Qe6+ but I'm sure

YASSER may agree that move may be prematch, a move like Qb7.

YASSER SEIRAWAN: Keeping all the positional trunks.

MAURICE ASHLEY: And Fritz is agreeing with that evaluation by giving more of a plus to white.
