Commentary for white move 17: For example, there's already a project underway at the IBM T. J. Watson Research Center to accelerate the -- to build a computer in the same style using an SP supercomputer and special-purpose hardware to solve the problem of -- pharmaceutical companies use in designing new drugs. They can simulate the behavior of a possible drug before actually having to synthesize it and test it in the lab. So you can save potentially a lot of time and get drugs to the market faster -- GK MOVE: 15 Rb2

MURRAY CAMPBELL: -- if you could speed up the process in testing.

YASSER SEIRAWAN: We do have a move. Garry Kasparov is playing -- it seems that Garry to me is playing the same cat-and-mouse game as the program. He's played Rb1-b2, not doing anything special with the white pieces, but certainly improving the position of the rook. The rook now on b2 always has this possibility of sliding over on the king-side, should it be -- should that possibility exist in the future. At the same time, it does prevent this knight on d4 from access to either the e2 or c2 squares. So in a sense the computer has passed. Garry has said, "Well, I'm going to pass as well, but at least my pass will give me that little-bit more significance. I had actually expected a little bit more of an active move from Garry and expected the move h2-h3 with the idea of maybe knight f2-g4. A quick question. We'll let the audience have one more question also, Murray?

MIKE VALVO: Murray wants to go now.

YASSER SEIRAWAN: Murray wants to go now. Okay.

MIKE VALVO: I wonder if something's wrong with Deep Blue? Why did he have to leave so soon?

YASSER SEIRAWAN: It's like, I can't think, let me get out of here.

MIKE VALVO: Oh, he's back. Would you like us to repeat that question? Mur miles an hour I will take one more, question.

YASSER SEIRAWAN: Quick question from me and then I'm going to take one from the audience. Does it annoy you that Garry is not playing like Garry? In other words, he's not his active self, what maybe you prepared for? Or is it a compliment?

MURRAY CAMPBELL: We have to prepare for -- we are prepared for the real Garry and the anti-computer Garry. (Audience laughter.) It doesn't annoy me. We just assumed that that was a possibility.

YASSER SEIRAWAN: And one question from the audience before Murray leaves. Please, sir. AUDIENCE MEMBER: If the point of the computer is to learn to do the most complex reasoning, and it obviously improves very fast, why couldn't you let it -- why couldn't you let Garry study its game program before? Because if he did, he would obviously very easily exploit the weaknesses and it would grow much, much faster and be much more able to play like a human player. I mean why didn't you let it -- why didn't you let that happen, if the point is to improve the computer? To make these very complex, human reasoning.

MURRAY CAMPBELL: Right well, we haven't actually played Deep Blue in any tournaments since last year. We've been working very hard in order to improve the program, and I'm sure if we let Garry have the program and run with it -- AUDIENCE MEMBER: No, I mean that --

MURRAY CAMPBELL: -- and practice with it -- AUDIENCE MEMBER: You must have made test games against you or other computers, and just show how it moved in response to other moves. And if you could see that, he could probably exploit it much better the weaknesses and therefore you could improve the weaknesses much faster.

MURRAY CAMPBELL: That's possible, would you also have Garry give us all his training moves -- AUDIENCE MEMBER: Well, you know his moves --

MURRAY CAMPBELL: -- excuse me -- all his training games that he's played against computers, and computer strategy? You would have that -- AUDIENCE MEMBER: If you want the best chess possible, sure. AUDIENCE MEMBER: I mean if the point is to make it -- if you know, for example, he will not play different against a computer than against a normal player. And he will /SPHROEU what he thinks the weakness of a computer is, not what's the best chess game, then wouldn't it be better for him to know and exploit them so that it didn't have these computer weaknesses.
