Commentary for white move 33:

MAURICE ASHLEY: To make nine moves /SKPERBGS better not miss a single tactic, because he would just lose immediately so he has to be feeling the pressure. But finish your point. Deep Blue with 50 minutes, lots of time.

GK MOVE: 32...Ref8.

MAURICE ASHLEY: With the not so veiled threat of RxNf3.

DB MOVE: 33 Nf4

MAURICE ASHLEY: A couple of quick moves from both sides. What I was thinking, if h5 could be effectuated, and this pawn, the g-pawn, were to capture it, then maybe the f5 square would become available for a knight. I'm not sure how that would work out.

YASSER SEIRAWAN: I don't see why the rook is any better, though, on the h3 square than it is on the g3 square.

MAURICE ASHLEY: Then you will be able to take with the rook instead of the pawn.

YASSER SEIRAWAN: But then I would still look to come down on g6.
