Isn't f5 first better? I'm betting for this: 1. f5 bxf5 (if blacks play another move like Qe8, white will continue with 2. fxg6+ Kg8 3. exf6 and black will have a very tough time) 2. Bxf5 Qe8 3. exf6 and similar position as before, the black have a inactive rook on h8 and the king is on a very difficult position
