It was a first round in Mondays club, my opponent was an old man, I had 4.5:0.5 score against him. He played Ruy Lopez, his move 7 was obvious, but not good, he had to play 7. dxe5 with equality. So after 8 moves I was up  a pawn. Computer criticizes his 10. c4, preferring simple a3.

Then he played 16. Nxe4, it was ~-4. The idea for Black was after 16… dxe4  17. Qg4 Qd5 18. Re1 to play  18… d3. I considered it, but thought that after 18…d3 19. Bh6 Qxe5 he will take on d3. But I could just play 19… g6 20. Bxf8 Bxf8 21. Bd1 Qxe5, it was ~-5 . So after 18… Qxe5 the game simplified. I was keeping some advantage, but then blundered playing 23… Rb6. It was a bad sign showing that I am not in a good shape.

We eventually transferred into a rook endgame, I was able to activate my rook for the price of pawn. Then he made a game losing mistake playing 33. Rb4?? , Re8 was winning. Of course I saw that motif with d2 and Re1+, but I think I started to see it later. Then I got that idea to sacrifice a rook on b2, then play c3 and get two connected passed pawns.

On move 37 I decided that I am ready, my king could go to d6 after rook check and cover c7 square. As soon as I played it I realized that he has a check on e2 after which the game is over. He thought for some time and played it. At home I found that he also had Rb7 + and then Ke1, stopping my pawns. In a few moves I resigned.
