Commentary for white move 11: DB MOVE: 10...Bg4.

MAURICE ASHLEY: ^ and ^ something we do see Bg4 has been played. And you've guessed the last two moves. GK MOVE: 11 f3

MAURICE ASHLEY: Yaz, this is the reason why you're three-time U.S. champion. He has played f3, attacking the bishop. That is the idea of an assault, a spatial gain on the right half of the board where black's king is, and Kasparov is a deadly attacker, probably one of the deadliest in history, certainly the top five in history.

YASSER SEIRAWAN: I don't want to defend against him! We're likely -- the position is actually extraordinarily sharp, because these are one of the things that I think is the computer's greatest strength. The computer's greatest strength is its resourcefulness. It looks at the paradoxical move because it looks at every move. So as the human player says, "Oh, this attack feels right," he or she will overlook a hidden defense. So Garry has taken not only the initiative, but he's also made the commitment. He's taken the /SPOBLT of playing e2-e4 -- and what do I mean by "the responsibility"? He has weakened his control of the d4 square so that later this black knight on c6 can plant itself on the d4 square. So by moving his pawns up the board he's taken the /SPOBLT and the commitment of continuing the attack. Now, let's look again. The bishop has got to go. If the bishop were to drop back to e6, a very unlikely situation, because we know that Deep Blue could lose a bishop or white could play f3-f4.

MAURICE ASHLEY: We do have a pause. Welcoming -- let's welcome to the stage a very important member of the IBM Deep Blue team, Murray Campbell.
