It was a second round in Monday’s club and I got this opponent, I played only one rapid game with him and won. So, my favorite Ruy Lopez, he played not quite by the book, but I decided to play simple. After the opening he blundered a pawn. Computer considers my 21. Qd2 as giving up the advantage, because after f5 my knight can’t go to d2. But he decided to exchange on c4 and then play f5.

It was a game losing mistake, he didn’t see d6. My bishop after a few moves from “bad’ became very powerful. I found 27. Ng5 and thought the best for him would be to give up an exchange taking on e7 and then on e6 after 28. Nxe6. But he went other way not seeing that it allows a smothered mate.
