In the following game which was played in a server tournament, I played the Bird Defense in answer to my opponent’s Ruy Lopez. White gained a small advantage in the opening and nursed it home when it turned out my counterplay with the N on the Q-side wasted too much time and allowed him to improve his position in the center along with picking up my d-Pawn. This game is the kind of positional stuff you see a lot of in CC these days where seemingly insignificant factors pile up and finally decide the game.
I don’t think resignation was premature. I was starting another tournament which included some very strong players, including an ICCF Senior Master, and wanted to devote more time to my remaining games.
