You are playing white, but black is cleverly playing for a draw.  Prove to him as quickly as possible that this won't work.

This interesting position is from an online blitz game I played right here on chess.com =).  The solution isn't hard (it won't stump you), but its tricky. I wasted moves to get out of time trouble in the actual game, rather then the solution shown in the puzzle.  I came up with the solution after the game, to prove to my opponent (in as few moves as possible) that this game was won for me with perfect play.
