In this game, I made an early exchange of my queen for his rook and bishop. At the time, I was ahead, though he managed to bring it back to roughly even with an effective threat on the queen side.
Here is the position now. I traded a knight for his pawn on c7. White to move; who has the advantage now? My feeling is this is a draw position, but I'm unsure.
