Commentary for black move 22:

MAURICE ASHLEY: No reason to open up the bank rank at some point, not going to be checkmated back there, the king didn't need any air. It's clear that Deep Blue had to defend the b4 square and that's what it intends to do. Now, Kasparov does other another means of attacking the position. He Luke's confused, though, his brow is furrowed, his face is in a frown. He looks like he's in a bit of shock relative to this move. The other thing, though, that I would like to point out is it's possible for Kasparov to also double rooks on the e-line. This pawn isn't going anywhere and he can think --

GK MOVE: 22...Ne6

MAURICE ASHLEY: And we will wait, hold our breath and see if the shocking b4 is played, and indeed Kasparov has walked away from the board, and we're wondering if b4 will come. While we wait there is a question from the audience.

AUDIENCE MEMBER: Just touching on the subject the art of chess, and we appreciate art, and are drawn to the analogy of paintings and I think how we appreciate chess now is probably along the same lines of how we appreciate say the Mona Lisa, and, you know, art galleries are full of those paintings that looked like somebody turned their back to the canvas and just threw paint over the back of their shoulders which can happen when the computer is playing crazy moves. But the question is, can we appreciate chess like this? Can human beings appreciate chess like this, or is because our appreciation for the art of chess is like in the vein of seeing what's beautiful in terms of what's fluid lines and what's logical, and when it's cam kazy we just can't relate.

MAURICE ASHLEY: I guess the question is are we too human, too logical to appreciate computers' backward logic, if you will, or crazy logic? Are we just too human and we laugh at these moves and say they don't make any sense.

MIKE VALVO: That's an excellent question. I think that we know that computers can create beautiful chess in a tactical sense. We've seen some incredible combinations that computers have played, especially in the early years. But your question is along the lines of especially in a position like this where the computer has the aesthetics of holding onto material, if I may coin a phrase -- (Audience laughter.) Kind of...

MAURICE ASHLEY: Kind of saying it's beautiful to be greedy?

MIKE VALVO: Yeah. Is that --

MIKE VALVO: Greed is good, Michael Milken variation, greed is good.
