♡ 42 ( +1 | -1 ) Caught out by an Expert sacrificeYou think you are doing so well. You are playing against an Expert. You are keeping him out. You think your defense is so watertight! But with a sacrifice your opponent can make your defense as strong as the Titanic. This is what happened in my recent game against apastpawn. I have put this up for public entertainment. It is also an instructive lesson in when not to counterattack.
In your anaysis you said "17. Ne2 bolsters the d pawn and opens a defense line to my a3 pawn." I disagree, Ne2 is a retreat maybe 17. Qf2 is better with the idea of getting your queen on the attack on the kingside and advancing your center pawns.
After that move you were worse. After black attcked in the center, you're next mistake is after 18...c5
You played 19. c3? This leaves a huge whole on b3 which the rook fills perfectly.
then after the queen moves out of the way (which is bad) came the rook sacrifice.
22. Rxf3 wins. Ion is right 24, Kf2 is better than what you played.
I'm not sure the rook sacrifice is "out of nowhere" black has sacrificed the exchange for a pawn and a strong attack.
