Rf7 looks natural
1.Rf7 (Threatening 2.Qf6+ Kg8 3.Qg7#) 1…Qxg5 2.Rg1 Qh4 3.Rxh7+ Qxh7 4.Qf6+ Qg7 5.Qxg7#
if 3… Kxh7 4.Qg6+ Kh8 5.Qg7#
What happens after
1. Rf7 Be7 ?
Qf6+ Kg8
Qf7+ Kh8
g6 hxg6
Qxg6
After 1 Rf7 Be6 2 Qh6 threatens both Qg7 mate and Qxh7 mate
1.Rf7 Be7
2. Qh6 or
2.Qf5 and mate at h7
Ok, 1.Rf7 is winning
But:
1.Qf6+ Kg8
2.g6 is also completely winning
for example
2…Rf8
3. Qe6+ Kh8
4. Rg1!
2…. Qh6
3. Nxe4 Bf8
4. gxh7+ Kxh7
5. Ng5+ Kg8
6. Qf7+ Kh8
7.Qf5! Kg8
8.Rf3! with many ideas like Rg1, Nf7
This Qf6 and g5-g6 Idea,
followed by the knight is
in my opinion the natural
way of attacking.
Unfortunately
1.Rf7 wins as well.
What everyone else said about 1.Rf7, except that on 1…Qxg5, I think 2.Nxe4 is more elegant, e.g. 2…Qg6 3.Qxg6 hxg6 4.Nf6 and mates.
