The two games that I played on consecutive Thursdays look reversed, it explains the title.
In the first game I had an opponent, to whom I lost recently having White in Sicilian. This time it was the same variation, but I played my regular Maroszy bind. He made a mistake on move 22 and I won a pawn.
Then I made two not very good moves – 26. Na4 ( 26. Nfe2 – +2.19) and 30. R2d5 ( 30. Nc3 – +1.43) and lost all my advantage. He had much more time than me and I started to get nervous, because the queens remained on the board. Then when I had 8 minutes left (he had 30) I touched my bishop wanting to cover from checks on the 1st horizontal and suddenly realized that I left unprotected the diagonal c5-g1. I resigned on the spot, was very upset.
In a week I got an opponent, with whom I have =2, -3 score. He had White and we played Queen’s Pawn defense. I thought that I intercepted the initiative after the opening, but instead of 20… fxg2 I had to play 20… Qh4. Soon he started to develop a counter-attack.
I made a big mistake playing 27… Bg6, I just thought that it will take off the pressure. After that in all the lines f5 was the decisive move. If exf5, then e6 attacking the rook and releasing the bishop at the same time. Interesting that we both did not see it. It got easier for me by the move 35, he also had 1 minute vs. my 10. I offered him a draw, but he refused. Objectively he still had a +2 advantage at this point.
Then he missed 43… Rxf4. 45. Rxf4 was a blunder, very similar to my blunder in the previous game. It would be a draw after 45. Rxg7+. The position became technical for me and in a few moves I won.
