Double Bishop sac, Queen goes to g5, winning.
Ng5. Black is toast. If Nxg5, Qxg5 and it’s over quickly. If black goes Bxh6, white replies Bxh7+ Kg7, Ne6+ Kxh7, Qc2+ then Black’s queen will have to say adios!
If black king goes to h8 after Bxh7+, then Nxf7+ Rxf7, Qxh6 Rxh7, Rf8+ Rdxf8, Qxf8#
double bishop sac?? Hmm,
1. Bxh7+ Kxh7
2. Bxg7 Kxg7
3. Qg5+ Kh8 or Kh7
4. Qxh5+ Kg8 or Kg7
5. Ng5 Bf5
6. Rxf5 and black can’t stop 7. Qh7 mate.
I really don’t think this puzzle is that easy.actually, a double sacrifice may not be sufficient.
ex:
1. BxN+ KxB
2.BXB kXB
3. Qg5+ Kh7 (Kh8 loses quicker)
4. QXp+ Kg7
5. and now Ng5 wont work because black has 5..f5
and the king scapes the checks.
instead
5.NXe5 (the idea is that if 5….PXN then 6. Qg5+ Kh7 7.Rf6 and next move mates.
now black can either try 5….f6 or 5..f5
5…….f6
6. Qg6+ Kh8
7. RXP RXR (forced since white threats Qh6+,Qg5+,RH6++)
8.QXR+ and that mates
5……f5
6.Qg5+ kh7 (6….Kh8 7.Ng6 loses)
7.Qd7+ Kh6
8. Nxd7 and I think white is winning
henryk has missed a mate here:
1. Bxh7+ Kxh7
2. Bxg7 Kxg7
3. Qg5+ Kh8 or Kh7
4. Qxh5+ Kg7
5. Ng5 f5
6. Qh7+ Kf6
7. Ne4+ mate
