And now another Quiz, but let me give you a hint. Black can force the mate in 4 moves. How should you look for the mate? If Black moves directly 13.Qf6+, White plays 14.Bf3. Here, if the queen weren't on d1, Black could move Qf6xf3 (the pawn g2 cannot move because of the pin). You have to think how you could deviate the white queen from d1, making possible Qf6+, followed by Qxf3+.
