Commentary for black move 27:

ANGELINA BELASKAYA: Okay. Okay, I'll take.

YASSER SEIRAWAN: You'll take my knight. c6xa5.

GK MOVE: 27...Qf4.

YASSER SEIRAWAN: He came back. Saved by the move, okay. We have a move by Garry Kasparov. Qf7-f4.

WILLIAM LOMBARDY: Hey, that's my move.

YASSER SEIRAWAN: Okay. What we had been looking at is a line where the queen for black shifted to the queen-side, this time Garry is offering the exchange of queens --

ANGELINA BELASKAYA: I thought -- but Garry played positionally.

YASSER SEIRAWAN: So tactics versus positional chess. So after the move Qf4, I would be very worried if I was white because the queen could threaten to come over to the c4 square. I really don't like what Deep Blue has done on the queen-side, and so I would probably choose to resolve the tension and play b5xc6, assuming b7xc6.

ANGELINA BELASKAYA: Yes, because if not, he will take the pawn with check.

YASSER SEIRAWAN: Okay.

ANGELINA BELASKAYA: I see it!

YASSER SEIRAWAN: I'm going to capture your queen because I'm a pawn up, and I want one of my principles in chess is that when you're a pawn up, you trade --

ANGELINA BELASKAYA: Go into an endgame.

YASSER SEIRAWAN: Okay, you take with the rook because you don't want to give me the opportunity for Nd4. Now I'll attack your rook. I'll go Nc3-e2.
