Win
7. Qh8 Rxh8 8. c8=Q Rh4 9. Qh8 Rxh8 10. b8=Q Rh4 11. Qh8 Rxh8 12. a8=Q Rh4
13. Qh8 Rxh8 14. Ra7 looks like a promising idea. White intends to play Rh7 and deprive Black of his h-file check for good.

Ah, it works because the black rook is at h8 not h4 or 5 so if the knight moves to f6+ the white rook interposes at h7. Nice. That ends blacks attack because the white rook is protected by the knight. One try for black in that case could be N-g4+ but that attack soon peters out and the white king escapes and no more checks and the white steamroller starts up for good.
