This quote belongs to Emmanuel Lasker. My opponent in this last round was a guy rated 1502. He had 6 years break and was just playing for a few months, his old rating was ~1800, I beat him in 2011. So we got French, Tarrasch closed. The book says 11. Nf4 was the best move.

On move 16 I saw a possibility of Bxh7+ sacrifice and played it. 19… Rh6 was a serious mistake. 20. Qe8 looked risky, but I calculated that my queen will not be caught. Then 21. Re1 looked like the right move, I didn’t see how he can defend his e6 pawn. That was a moment when I think my bad shape started to show up. Not only I missed that he can force the exchange of the queens, but I didn’t see Ba3, the decisive move. I was so much concentrated on the kingside and forgot about the queenside. So the only move after 21. Ba3 was 21… Qf4 and I had to find 22. h4!.

After 22… Rxh4 23. Nxe6 Bxe6 24. Qxa8 Black is lost, 22… Rb3 23. Nh5 Bd7 24. Qxd7 Rxh5 25. Bxf8 Rxf8 26. Qxe6 White is +3.50. So I missed that opportunity and the game continued without queens. Then after 26… Rh4 I didn’t play 27. Rc7 Bc6 28. Rxe6, I saw only Bc6 locking my rook. 32. h3 Re4 33. Ng4 Bh4 34. g3 Bg5 was keeping the game equal.  My 32. Bc3 and 33. Rdc1 were not good, 33. Ra1 could save the day.

Then he also didn’t play exactly, my taking on b7 was right, even I thought later that it was a mistake. 38. Rc7 was a bad move, 38. h4 was equal. Soon my position deteriorated and I lost.
