ASTC Game #4 - Secondary Open

Study the position:

- White's pawns offer little protection for the king

- Black's rook controls the f-file

- Black is set to launch a discovered attack on White's king
        which is on the same diagonal

White to move played 21 0-0-0  (castle queenside)

Cool Black then forced checkmate. How ?
