It was a round 1 of the Mondays tournament. My opponent was a girl rated 1475. I had White and we played Ruy Lopez. We got a position with a closed center. I missed 22. e5 dxe5 23. Bf5 winning an exchange.
I tried to develop an attack on the kingside, she was maneuvering pretty well. Somehow I lost the initiative and could get worse after 32… g5. I soon got annoyed with all that and decided to sacrifice a pawn in the center. Actually I had to play 36. d6 after her 35… dxe5 that was a mistake and I would be much better.
Anyway the position became dynamical and not easy to play, that was my intention. 45… Qd8 was not the best move, better Qa7. Then she made a decisive mistake playing 44… Kg7. I saw the possibility to promote with check and played it. Being almost a rook down, she blundered and resigned.
