well i haven't really looked at the opening/mid game, but your endgame was extremely sloppy.
37. Kf2 seems to give up a pawn for no reason
at move 40 it seems moving the bishop and then attacking b4 pawn is a simple win
i think you flagged at the end here, 50. Nc5 seems drawn
at the momment i have no software to analyse it, in the game i felt like i should be winning but sudenly i lose can you help me to give me a feedback about this game?
