The last few moves have favored Black. The problem of the Na6 has been solved, he has the bishop pair, controls the only open file, and has an outside passed pawn. I'd say black is better here.

? Now white gets the initiative. Instead Black should get his center pawns going with 24...e6, preparing a subsequent ...d5 and making some more passed pawns.

And black's pawn structure mangled with it. The d-pawn is now backward to boot.

There's no good discovery, so black should just play 25...Qxe7 rather than letting the Q get kicked around.

i agree: I haev been surprised he did not take the knight.

? Black didn't calculate this through. His Q will now be bottled up after 33.g3.

White misses the subtle 33.Nc6! For example 33... Qxh3? 34.Qe7! and I'd be surprised if black lasts more than another 3 or 4 moves.

unfortunately I am not that subtle. That is why you are 2100 and I am 1700
