A Sacrifice Win in the Ponziani

In this game I played the Ponziani with White. My aim was to get center control and kingside space without opening the center early, and then attack Black's king. My opponent played a bit passively in the opening and missed some opportunities to equalize. I exploited his lack of maneuvering area and not-so-well developed pieces with a space-gaining pawn sacrifice which started my attack, and the outcome of the game was clear a few moves later.
