These games were played last Thursday and Monday, in rounds 4 of the respective tournaments. In both cases I had White and my opponents played Sicilian Defense. I didn’t find the right plan and made some tactical mistakes in both games.
Thursday’s game – my opponent was an old former master, I had +1, -1 score with him before. We played Sicilian, Moscow variation, I chose a quiet line. Then it was a positional play until we reached move 23. After his Qc6 I saw that I can win a pawn on a5, but thought that after rooks exchange he will catch my knight – 24. Rxa5 Rxa5 25. Nxa5 Qa4, but didn’t see 26. Qa7. If you would look at the end of the game you would realize how crucial this pawn was. I played 24. Raa1 and after a4 he intercepted the initiative. Then instead of 27. Ra2 I played Qd4. The idea was close – to do something against the “a” pawn, but what was needed was blocking. Then on move 29 I missed it again and quickly got really worse. His attack developed and soon I lost.
Monday’s game – my opponent was a Russian speaking boy, who grew from a “B” class player to a master on my eyes, my score with him in the last 4 years was 2.5:4.5 (with a positive score in a few years before that). He played Sicilian Defense, I chose Rossolimo variation. It went wrong almost from the beginning, when I decided to develop my bishop to b2. Then it was a very bad idea to take on f4. As soon as I played it I realized that when I will move my knight after 17… exf4 he can play f3 with really serious consequences for me. But he probably didn’t see it and played Rxf4. It was difficult to find the right moves and I was getting worse and worse. On move 28 I decided to sacrifice a pawn, but it didn’t give me any relief. In the endgame his queen was very strong and it decided the game.
