It was a last round in the Thursday’s tournament, I got White and my opponent was a young guy rated 1870, never played him before. So, he played Caro-Kann and I chose a most popular line. After 11 moves we had a theoretical position (I didn’t know about that) and c3 is considered a move preventing White to castle queenside, which would be not a bad idea considering what happened in the game.
After he played 17… g6 the best would be 18. Qf3. Then 19. Ng5 was also not a very good move, I wanted him to put a rook in a passive position defending f7 and forgot about Ne5. So, after 20 moves a had a feeling of some instability in my position. Then I just missed his 21… Nxf2.
Interesting that my 23. Nxh5 took him by surprise, he looked confused. Maybe it explains his 23… Nxh5, which was a mistake. But I already had a premove 24. Nxg4, played it quickly and didn’t notice the obvious Rxf7. But then he made another mistake playing 24…Qg3. As soon as he played it he offered a draw.
I agreed without thinking, knowing that I am worse. He even asked me: “Are you sure?”, I said: “Yes”. Actually he had only ~0.25 advantage after queens exchange, so it was not an error in judgement from his side, error was playing Qg3 instead of Ng3 which was keeping his advantage.
