I saw this coming.

@jkarp: here it isn't, because it prevents White from having to retreat his rook immediately and it wins another pawn.

Right.

This is where I am not sure. This exchange you did. I read ahead and read the annotations. I may be missing something here. I would have kept the bishop at g5 and done Rg1.

Yes that was an option - I just wanted to keep it simple!

@jkarp: he is playing for trick because he is losing so just playing normal moves won't help anyway, and also because he can get the initiative with it.

White has played very well up til now but this mistake could have changed the outcome of the game. 26..Qxg5 27.Nxg5 and now (as you pointed out in your previous comment) 27...Rxg3 picks up a rook.

If 26..Qxg5 27.Rxg5! preserves white's advantage.

@jkarp: he's going for the attack now and the rooks will come off sooner or later anyway.

@jkarp: it was not doing anything useful on b7.

Great annotation!
