Commentary for white move 15:

MAURICE ASHLEY: Now, it's interesting, because it seems like the same thing has occurred that happened yesterday. The position was blocked, closed down, we were wondering what's going to happen, neither side was aggressive, and then suddenly the computer figured out a way to be aggressive, to open up the game, to initiate pawn contact. And Kasparov has found himself again wondering about how to control this initiative, how to make sure that a computer doesn't get the kind of position it really loves and plays extraordinarily well. Is this something that always happens? Is it impossible to keep a position locked? Is Kasparov having a strategy in trying to keep it closed? It seems the computer has managed to open it up yet again.
