Blacks last move was a6?? Why the question marks and what was necessary?
1...a6??
2.Bxh7+! Kxh7 (Kh8 3.Qh5)
3. Qh5+ Kg8
4. Ng5 Bxg5
5.hxg5 ++-
Perhaps instead of 1...a6, perhaps f5?
I think white can win with one of these variations.
This was too easy! Yes of course:
2. Bxh7, Kxh7 3. Qh5+, Kg8 4. Sg5, Lxg5 5. hxg5, f6 6. g6
1. ... f5 was best.
