A Sharp Two Knights Defense with Black

This game was rather imbalanced as I was a pawn up from the opening but White had compensation in center control, space advantage and more active pieces. The middlegame was very dynamic. We exchanged a series of mistakes in sharp positions, while noone could keep the lead for long. But it was my opponent to make the final blunder. It gave me an endgame position with serious advantage, which I converted into a win.
