It was a last round, I was leading by 0.5 point and convinced myself to go despite having a quite stressful day just because didn’t want to give up the first place. As in a few recent games I played again Moscow variation and my opponent again played Nd7 line. Computer says I had to exchange the rooks on move 11 and then play Na3. His 11. Ne5 was a mistake.

I gradually increased my advantage and won a pawn. Computer criticizes my c4, preferring Qc4 and says that after move 25 my advantage was only ~0.3. It is difficult for me to believe it having two passed pawns on the queenside. Anyway on move 26 I blundered, my mental state suddenly showed. Being in a state of shock I lost another pawn, Qc5 right away or after Qa7 was saving it.

I got mad at myself and tried to get some chances, though the position was equal. He offered a draw, I refused, he looked surprised. Soon he made a mistake and I got the pawn back. His next move 39… f6 was a big mistake. On move 41 I missed Qc7 just because I didn’t like Rb7, but I didn’t see a mate in 2 – Rh7+ and Qg3#. Still after 44… Qh8 I got a decisive advantage.

I found 47. Be6, then my bishop went to f5. He had 1 minute remaining, I had 4 when I saw that I have a forced mate.
