  1.Bf6+ Bxf6 2.Qg3+ with an idea of mate by Qg6 or Qg8.

  Suggest
  1.Bf6+
  if 1…..Bxf6
  2.Qg3+
  and mates with Qg6 or Qg8.
  so 1…..Kf7
  2.Qxh7+ Ke8 trying to escape
  3.Nxc8 seems the best amongst lots of possibilities because here comes Qe7#
  3……Ra2
  4.Nxa2 and Black can only delay but not prevent Qe7# mate.

  Bf6+! (this move is seductive because it is one of the available checks, and leaves black with 3 legal moves)

  ..Bxf6 Qg3+! Kf7 Qg6+ Kf8 Qg8#
  ..Bxf6 Qg3+! Kh8 Qg8#
  ..Bxf6 Qg3+! Kf8 Qg8#
  ..Bxf6 Qg3+! Bg5 Qxg5+ Kh8 Qg8#
  ..Bxf6 Qg3+! Bg5 Qxg5+ Kf8 Qg8#
  ..Bxf6 Qg3+! Bg5 Qxg5+ Kf7 Qg6+ Kf8 Qg8#

  ..Kf7 Qxh7+! Kf8 Qg8#
  ..Kf7 Qxh7+! Kxf6 Ng8+! Kg5 Qh6#
  ..Kf7 Qxh7+! Ke8 Nxf5! (no defense to mate, for example: Nxd5 Nxd6+ Kf8 Qg7#)

  ..Kf8 Qxh7
  Black’s only move to prevent Qg8# is Ke8. After Be6 dxe6 there is no defense to Qf7#

  So:

  ..Kf8 Qxh7 Ke8 Nxf5! We have an identical position to earlier, where there is no defense to mate.

  I see Andrew sees what I see. Is a mate in 5 considered messy?
