Commentary for white move 22:

MIKE VALVO: It's like a permanent advantage for the white pieces?

ROMAN DZINDZIHASHVILI: Permanent? Yeah, it's solid. GK MOVE: 22 gxf4

ROMAN DZINDZIHASHVILI: Okay, what can we suggest for the computer? Maybe Nxg4, and if the knight recaptures, there's something like f5, try to open the position for my cost, and on Nd5, some kind of Nd5, maybe Qd8.

MIKE VALVO: Then maybe Rb7.

ROMAN DZINDZIHASHVILI: Rb7? Well, Rb7, pawn takes knight.

MIKE VALVO: Knight takes bishop.

ROMAN DZINDZIHASHVILI: It's a possibility, but I think black has some life here. This is activated. This is not as dead as they were before. Bishops are playing, and also maybe --

MIKE VALVO: A pawn is hanging. These are just possibilities. AUDIENCE MEMBER: Take back with the queen instead.

ROMAN DZINDZIHASHVILI: I think in this position, we just have -- computer does see that if it doesn't get counter play real quick, that it can be strangled. The question is, how dangerous it thinks now the position is. Otherwise now, if black does not play Nxg4 and f5 to show some activity, I don't think the computer is going to last long. So that's why I think Nxg4 is almost a necessity.

MIKE VALVO: Well, how would you play for white after Nxg4?

ROMAN DZINDZIHASHVILI: I don't know. Maybe queen takes on g4, preventing f5. Probably Qxg4. Now black cannot play f5. It still doesn't look good, with the knight d5. It doesn't look good because f5 drops the bishop on g6. So that doesn't look good, either.
