Commentary for white move 9:

YASSER SEIRAWAN: We'll pause our analysis of game two and return to the game position, and the predictable move was Ng5. And by the way, I must say that when I play against the computers, one of the things that I am really, really terrified of doing is getting way behind on the clock. The computer is so devastating in those tactical nuances that it's something that I could easily miss, and I never want to get into time trouble against the computer, because that's just death, that's just death. We do have a time. Garry has taken 37 minutes for his first nine moves, considerable amount of time, and Deep Blue but 14.

MAURICE ASHLEY: Somewhat surprising Garry taking so long on that move, don't you think?

YASSER SEIRAWAN: An obvious move, in my estimation, and definitely a mistake to get behind on time so early. And this is a very early stage. But I can say that Garry, to his credit, when he does go into these deep thinks, if you'll pardon me for a moment, he really gets the Zen of the position, that is to say he really, really gets a great feel for what is going on, and it does allow him to play the next few moves quite rapidly.

YASSER SEIRAWAN: And he's not in any --

MAURICE ASHLEY: And he's not in any time pressure, nine moves, used a little over half an hour. If he plays the next few moves with a little bit of pace he'll be right back on track.

YASSER SEIRAWAN: Exactly. One of the great chess players, Bobby Fischer, was famous for taking a long time in the opening and then playing the middle game very, very quickly thereafter and wrapping up the game quickly.

YASSER SEIRAWAN:

MAURICE ASHLEY: What is the key point behind this move Ng5? Why is it so horrifying for black to give up this bishop, this attack on this bishop on e6?

YASSER SEIRAWAN: Well, there are several deep points. The first is that if you take a look at white's king for a moment, it's wonderfully shielded. This is really a very well protected king, and this bishop on g2 performs fantastic defensive duties in protecting the king, and at the same time it's also very offensive. This entire h1-a8 diagonal -- Let me just set up threatened squares for a second. And we'll go back, and now we'll go forward, and after just highlighting the chessboard for a moment, we get to see all of the squares threatened, and this bishop on g2 is on this beautiful defensive diagonal. Let me take this off, the "threaten move." And so black has tood something about that bishop. He has to get rid of it. If he loses the counterpart, the bishop on e6, then that B on g2 is going to stay on the board the rest of the game and give white a considerable advantage.
