Commentary for white move 18:

YASSER SEIRAWAN: Well, exactly. And to Garry's defense, obviously he's been spending a great deal of time looking as these things and maybe he's found a way that he could solve his long-term problems. But optically, just a very quick, you know, look-through, I would be very dissuadeed from this. Just, you know, going back a couple of moves to this position, I would have been reaching for my c-pawn and playing c6-c5.

MAURICE ASHLEY: We do have a youngster, is it Mariano again who has a question? What is your question?

AUDIENCE MEMBER: Yeah. I don't know whether you explained this before or not, but is the Deep Blue computer programmed to play Kasparov's style?

MAURICE ASHLEY: We will get to that question.

DB MOVE: 18 Rg3

MAURICE ASHLEY: Let's do two things. First let's mention that Deep Blue has played the move Rg1-g3, that's its first move, boll sterring the knight on f3, and then let's excuse our wonderful Grandmaster.

YASSER SEIRAWAN: I leave you in good company. Thank you.

MAURICE ASHLEY: Perhaps you can explain, mike, -- Mike, the example of programming a computer in a human being's style, especially Kasparov, into the language of Deep Blue. What is the possibility of that occurring?

MIKE VALVO: It's possible to do that in programming, and getting the machine to play very wild to very conservative. But I think for the most part, the general style of every computer is like Kasparov is when he's not playing computers. Kasparov when he's not playing computers is trying to make it as complicated and as tactical as possible. This is not the normal Garry we see in a human event. In fact, that was a concern of most of the reporters that I spoke to upstairs, why is Garry playing this way, how is Garry playing this way, how has he altered his style, is it becoming like the machine? What's going on? And that was the focus of attention up there.
