It was a second round in Monday’s club, my opponent was a young man rated 1699, I drew him 3 years ago. I got White, we played again Rossolimo variation.  It was equal until move 20, then I played Ne4. It was a right idea to use the pin, but I had to play g4 first, if 20. g4 Bc8 21. Rxe8 Rxe8 22. Ne4 White eventually wins d6 or c5 pawn (if Black plays d5 at some point).

We spent a lot of time by the move 25, he spent more, maybe it was a reason he blundered a pawn. I had to play 30. Kc4, I saw it, but didn’t like the diagonal check, not seeing that after 30. Kc4 Qf6 31. Kb5 Qf1+ I had c4. Then I missed his Qe5 reply when I played b4. A few moves later he went for a perpetual.
