1.Bb5!!
White defends his back rank, and, in doing so, puts his third piece en prise! Not one can be taken however: if 1... Qxe4 2.Ba6#, or 1... Bxa3 2.Ba6++, or 1... cxb5 2.Qa6+ Kb8 (or Kc7) 3.Bxd6#
So Black resigned, somewhat prematurely, though 1... Rhf8 2.Bxd6 Qf1+ 3.Bxf1 Rxf1+ 4.Qg1 Rxg1+ 5.Kxg1 leaves White 2 pawns up once the e5 pawn falls
