I would play BXF5. Black comes back with NXB, then white plays QXN. White’s queen, rook, and forward pawn are now in prime position for the death blow.
If black tries to check on the backside with the Queen or c8 rook, just block it with the bishop at h2.
1) Bd6 seems like a good move
1…Rxe7 if 2.Bxe7 then Qf7+ and Bxf5 mate.
1 Rxe7 Rc1
2 Re8+ Kh7
3 Bxf5+ g6
4 Be5 maybe ??
1.Re7: Rc1
2.Re8+ Kh7
3.Bf5:+ g6
4.Qc1: Bc1:
5.Be5 gf5:
6.Rh8+ Kg6
7.e7+-
