Commentary for white move 10:

YASSER SEIRAWAN: Mate. GK MOVE: 10 e4

YASSER SEIRAWAN: He did it just before I got a chance to say it . (Audience laughter.)

YASSER SEIRAWAN: Honest Injun, honest Injun, I was going to say it. The idea is a king-side pawn storm. Because of -- it was actually mates that motivated me to think in this direction. We know from game one that the computer did everything to preserve the bishop. So white you had said that, I realized that what Garry is thinking about is a cat-and-mouse game of chasing this bishop on f5 and pushing all of his pawns in order to try to capture the bishop, but not with the idea of capturing the bishop but with the idea of capturing the king. What I saw was that after e2-e4 comes the move -- let's say that the computer would play the move Bf5-g4 attacking white's queen, a very sensible looking move. Then would come the move f2-f3. The bishop would drop back to h5. There would come a move, for example, like g3-g4. The bishop would have to drop back. A move like h2-h4. You notice that white is pushing his pawns up the board on the king-side. h7-h6. It almost looks like a desperate attempt at checkmate, but you might see a move like, for example, h4-h5. And now the bishop could have several moves. It could drop back to h7. It could take on 5 h5. It could be the move hxg5. And so white would get an early assault on black's king.

MAURICE ASHLEY: Also, could he have dropped back in this position? After h4 maybe the knight could just retreat and keep the same kind of ideas?

YASSER SEIRAWAN: Indeed. The idea of just keeping the gains made by this pushing of the pawns on the king-side. Let's just take another look at these kinds of ideas for a moment, because they are very intriguing. We're looking at the move Bg4 now for Deep Blue, f2-f3.
