It was a strange game. I got White, with a boy I played 4 times before, =3, -1.
I knew he would play Petroff, so I decided to try a new line I looked at some time ago, here is the game. I didn’t expect f5, then thought I’ll try to get two bishops. Then for some reason I decided to exchange the queens.
We played with a 30 seconds increment, nevertheless I played unusually fast, spending 22 minutes on 28 moves. First it costed me a win, when I automatically played prepared move 22. Rxa7 missing that I can win a knight. Then it almost costed me a game. Instead of attacking with a 26. Rc8 (not sure that I would find all other moves like g4, that Houdini suggested) I got that bad idea about exchanging the rooks, thinking that I will have a better B vs. N endgame.
It was a mistake, I lost a pawn and realized that I have to fight hard for a draw.
My strange, don’t care mood that evening helped me at this moment, I switched to the defending mode without delay.
After my 36th move objectively it was lost, though a win required exact play from him. But he made a mistake, which I didn’t use playing 41. Bf6. He had a win in his hands, but lost a crucial tempo with 42… b3. I played exactly from this moment, bringing my king to the queenside.
It was a funny position after move 48, when he couldn’t take my bishop on a1. Since then it was a draw, he tried to do something, I just tried to play carefully and watched for 3-fold repetition, still missed one – after White moves 62, 64 and 72. Anyway, eventually he realized that it’s a draw and basically forced it.
