This was a game in our Summer Tournament. I was White against a Leningrad Dutch. I misplayed the opening and didn’t give myself a clear pawn lever plan to play for. Nigel’s comments on the possible lever play later are worth studying.
Once I had got my bishop to f3 I was back on with a possible future e4 lever. However, my recapture with the knight rather than the queen on move 14 is an instructive error. If I had taken with the queen I would have kept the possibility of playing e4 alive. Taking with the knight showed that I wasn’t aware of the key plan.
My move 34 was poor. If I had swapped my knight for his bishop it would as Nigel pointed out have been a simple winning pawn endgame. I think I was still thinking of the way my knight had dominated his bishop and wasn’t alive to the favourable transition.
