It appears to me that White has a slight advantage in this match, if only he can break through on the king flank. However, his dark-squared bishop seems to be hampering his ability to deploy his pawns and really open Black's position.

What do you think of the following. Is there something one can do with that bishop other than sacrifice? Is 13. f3 really the best move?
