White also wins by 20.Bxh7+ Kxh7 21.Qh5+ Kg8 22.Bxg7+–.

23...Kxg7 24.Qg5+ Kh7 25.Rf3, and Black is mated.

Black resigned.

The bishops look threateningly at the white king. Everything is ready for the combination:

13...Bf3 14.Nxd6 Bxd1 15.Qc4±.

The key move and an important subtlety! Black forces White to close the second rank, and only then makes the second bishop sacrifice on g2.

Everything else loses:
A) 16.Be2 Bxg2 17.Kxg2 Qg5+ 18.Kh2 Rf6–+.;
B) 16.e4 Rf6–+.;
C) 16.d5 Qg5 17.g3 Qh5–+.

A) 18.Rf2 Qh1#;
B) 18.Bxf5 Rxf5 19.Qe4 Qxe4 20.fxe4 Rg5–+.

White resigned.

On 1...Ne6, there follows 2.Rc2! Qc5 (2...Rfd8 3.Ne7+ Kh8 4.Qxh7+ Kxh7 5.Rh2#; 2...Rfe8 3.Rh2+–) 3.Rh2+–.
