Commentary for black move 38:

YASSER SEIRAWAN: Again, let's take a look at the position Ne4 by Deep Blue, because I feel that this is the right move. Ne4 Rxg7+ Kb6 g6. And let's try the move Rg5; because that way I'm behind the passed pawn, which is the -- rooks belong behind passed pawns, the famous quote. All of you chess players out there familiar in the quote?

DB MOVE: 38...Rd7

MIKE VALVO: If this were a school room, it would be pasted on the wall.

YASSER SEIRAWAN: We have a move. Deep Blue did not play what we had been anticipating, Ne4. Instead it has played Rd5-d7.

MIKE VALVO: A little more passive but might be okay, too.
