C99 Closed Spanish Game: Chigorin Defence, 11.d4 Qc7 12.Nbd2 cxd4 (1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 Nf6 5.O-O Be7 6.Re1 d6 7.c3 b5 8.Bb3 O-O 9.h3 Na5 10.Bc2 c5 11.d4 Qc7 12.Nbd2 cxd4 13.cxd4 Nc6 14.Nb3)

This game was played in a mini-tournament called "dim_weasel's XIV". Five players took part to this mini-tournament and I was third in the final standings due to tie-break. I was able to gather 2.5 points in 8 games. I shared the third place with two other players and we had to share the third place prize, which was 1 mini-tournament point. It meant that each of us got 0.33 mini-tournament points... My opponent in this game, mhead123, was second in the final standings with 4.5 points.

I started go wrong in the position below when I played 21...Qa5. Up to that point I had things more or less in control. That is not to say that I could not improve my game earlier on, but the first sign of real trouble was my 21st move.

The moves that the engine likes here are 21...Nc5 and 21...Qb7.

I should have gone for the move 21...Qb7 instead. Mhead123 missed his or her chance and played 22.Rac1. It let me off the hook a bit and I had a chance to fight for the draw again. It was better to play 22.b3 or 22.b4 instead. I was able to hang on quite well in the game until we reached the position below, in which I blundered by playing 29...Rc8??

Getting rid of the backward pawn on b5 by playing 29...b4 seems to be the preferred choice here and the position would be roughly even.

I should have played 29...b4 and equality might have been reached. However, the game continuation was hopelessly lost for me. Mhead123 correctly saw the continuation that quickly ended the game, 30.Rxc8+ Bxc8 31.e5. After 31.e5 I resigned because I either lose the knight or get mated.
