Commentary for black move 16:

GK MOVE: 16...Bc6

MAURICE ASHLEY: Defending his pawn, and again getting up from the board, walking away and he's prepared it looks like a little cubbyhole for the king on b7.

YASSER SEIRAWAN: Nice, nice.

MAURICE ASHLEY: Which would solve the problem we're talking about of the a8 rook and slowly but surely we see Kasparov trying to solve all the problems. And if Deep Blue doesn't come up with a concrete plan soon, it could very easily find itself down a piece. But in the meantime there's so many possibilities for attack, Yaz, and again you're busy exploring one just now. I can't keep you /EURPBD control, you just want to --

YASSER SEIRAWAN: It's exciting possibilities here for Deep Blue.

MAURICE ASHLEY: What was that last one about? You're thinking of maybe the move Ra6?

YASSER SEIRAWAN: Well, after the move Bc6, you're absolutely right, Garry is preparing that nice little box for his king on the queen-side with Kc8-b7 and I was just looking at Ra1-a6, just going all out for the attack.

MAURICE ASHLEY: Attacking the bishop on c6, which is currently undefended.

YASSER SEIRAWAN: Now, the bishop can't drop back, the bishop can't go back to b7 because of that e6 pawn would be munched. Ra6xe6. So Garry would have to make one of several choices. He's either have to bring his king to b7, which is the first and most obvious choice, and then I was thinking a sacrifice, just Rxc6 Kxc6 c4. This is probably not going to work as far as an attack is concerned, but --

MAURICE ASHLEY: Looks tempting.

YASSER SEIRAWAN: There's some dangers in this position. For example bxc4 --

MAURICE ASHLEY: I should just note for the moment that Fritz 4, despite being up loads of material --

YASSER SEIRAWAN: A whole rook.

MAURICE ASHLEY: -- a whole rook, is saying it only has a tiny advantage as black which is a concession on Fritz 4's part, which is saying I'm only up a rook, which is five points, but here it says it's only up a pawn, which is a certain begrudging admitting that there are certain dangers here.

YASSER SEIRAWAN: bxc4 Qxc4+. Garry's king would have to drop back, and --

MAURICE ASHLEY: Either b6 or b7?

YASSER SEIRAWAN: Probably b7. And unfortunately now in this particular case, if our bishop on g6 were to assist our queen, we could do something wonderful like Qa6 checkmate or things like that. So these are the things that Garry has to worry about.
