Round #1 of the annual club championship. Lately my practice games have been going well, so I approached this tournament with optimism.
My opponent was a class A player who I have not played before. My color was Black and I usually play the Petroff against e4. My opponent transposed into a Four Knights Game, maybe because of unfamiliarity with the Petroff and I was equally unfamiliar with the Four Knights.
The game was going well into the 2-hour mark when I violated one of the basic tenants of endgame play: slow down. I left my Knight en prise and was facing the probable loss of an additional pawn when I resigned.
Lesson learned: Slow down for endgames.
