I played two games this week after a long break, Caro-Kann defense with different colors.
In the first game I had Black. It was an Advance Variation, computer recommends playing 12… Rc8 and 13… h5. Anyway I was OK until I played 15… Nh6 instead of Nh4. After 19. Nf4 I had to give up an exchange due to Ng6# or Nxe6 threats. Instead of 20… Na5 I had to take on b2, then Rdb1 leaves d4 pawn without defense and Rab1 is not good either, so 21. Qd3 is the best.
His 29. Qb1 was a blunder, it was strange because he had a lot of time. Computer says 34… Qg5 was a mistake and recommends 34… Rd3 with ~-3 evaluation. 37. Rf2 was another blunder, he could play Rd1. But then I made a mistake that decided the game. I hesitated to take on g4, after 38… Rxg4 39. Kh3 Rxg3+ Black is ~-4. After he played Rcf1 the position became equal, but I lost the initiative and was in time trouble. So no wonder I played 39. Bc5? instead of equalizing Rd2. After 40. Rf8 it became really bad, 40… Qxf8 was also losing, I evaluated that right. 41. Qb7 was played with 6 seconds on the clock.
In the second game my opponent was a young man, I played him 3 months ago and drew with White in Caro-Kann, he played Caro-Kann again. His 28… Rh6 was a mistake, after 28… Nxh5 it was equal. The same thing a move later, 29… Nxh5 was a huge mistake, I calculated right that g2 and g3 pawns will defend my king against the queen on h5.
But by move 32 I had only about 5 minutes left and made an error playing 32. Rxe6, instead Qa4 with 33. cxb7 after 32… Kb8 or 32… a6 was winning. Then I had to play 33. cxb7+ Qxb7 34. Qd3 covering b1 square. 34. Qf6 or 35. Qf6 was leaving me with some advantage. Instead I allowed a rook check on d1 and then even 36. Kf2, which was not risky as I thought seeing Qb6+, lead to an equal position anyway.
Still he made another mistake, taking on b6 with a pawn. There was a 41. g4 pawn sacrifice that was winning, but with less than a minute left, playing on 15 seconds increment, I didn’t see that. Then it was a pawn race and soon after we got into a queen endgame he offered a draw which I accepted. The final position was equal.
