Black's backrank is weak, only protection against Qd8# is the c7 bishop. So therefore:

1. Be5! Nbd5 (anything better?)
2. Bxc7! (more direct than cxd5 I think) Nxc7 (anything better?)
3. Qd8+ Nce8
4. Bxe8 g6 (Nxe8? Qxe8#)
5. b6! Qb1+
6. Kh2 Nxe8
7. Qxe8+ Kg7
8. Qb5!!
Plenty variations I think, but is there something better for black?

1. Ba1-e5, intending an eventual back rank mate.

1. Be5! wins (threatening 2. Qd8+ and then checkmate). Black has to give up his Bishop to avoid checkmate.
