Commentary for black move 13:

YASSER SEIRAWAN: Cagey one, too. Any picks up this year with Deep Blue so far? We know that in the Philadelphia match, one of the opening files were scrambling at the last moment had gotten deleted.

MURRAY CAMPBELL: Nothing like that has happened yet. It's had full access to its opening library. Garry has done his Beth -- DB MOVE: 13...h6.

MAURICE ASHLEY: As we saw in game one, the move h6. The same situation as here. Not any danger of losing the bishop in this position, Yaz. Do you think it might want to launch that assault as it did in game one with the move g5 again?
