White to play and win
White played here 1Qf8+!. The f8 square is controlled indirectly by the Rook on d8, allowing for that move.1..Rf8 2 Rf8 is Checkmate.

1. Rf8+!; Rxf8 (a forced move)
2. Rxf8#
no, 2.Rxf8 is a bad move because black will respond with another Rxf8 which puts white back to the drawing board, if he promotes the pawn black will just take it with the king. though it does not follow the xray tactic perfectly, 2.Pxf8=Q or R is better because it directly results in mate. it is protected from the king by the rook on d8 and the knight because white's bishop is pinning it
