5 Piece Combination Checkmate

Looking at the graphic image above which shows the position of pieces at game's end, you can see that while my f2-Rook delivers the mating move, each one of my other pieces: Queen, King, Knight, and pawn is actively covering one or more of all the White King's possible flight squares. He's dead where he sits and he has no safe place to go.
