Sacrifices don't mean much if you loose. Weren't you playing White?
3 minor pieces sacrifice

Its common sense that he was black :D
Very nice! especially for a 1200 rater :D
Yeah sacrifises are worth it when you chase the other persons king

That's no biggie. I sacrifice at least three minor pieces in each game I play. It's just that it's usually unintentional . . . =D

Black's 15th move doesn't deserve "!!" because its main advantage was only psychological... a clearly materialistic White grabbed the pawn with his King, which was, of many poor moves, perhaps the worst judgment-wise. After Kb3 he has a little bit of breathing room and can attempt to back his King into the corner. (White's 15th move was pretty bad too, as he wastes a move that could have brought his King back to his side, and he weakened his pawn structure.) Even then, you would have already gained 3 pawns to his piece and a vastly superior position. You are definitely capable of taking on tougher opponents successfully.

In this short game I played I sacrificed no less than 3 minor pieces!
