Qxh2+ is a surprise. Since the queen is guarding every square the white king can move to and white can't capture his or her own pieces white's king has to take the black queen. Black uses his or her rook to check. The rook is guarding squares h3, h2, and h1, The bishop is guarding squares h3, and the pawn on f4 is guarding square g3 white's king has to move to g2. Then the black bishop swooped down to h3. Checkmate!
