1. Qg8+ Kh6 2. Qh8+ Kg5 3. h4+ Kxh4(if 3..Kf4 then 4.Qh6+ winning the rook) 4. Nf5+! gxf5(if 4..Kg5 then 5.Qh6+ winning the rook) 5. g3+ Kxh3 6. Qxh5#
correction: not ok 4.Nf5+ as, after 4..gxf5; 5.g3+ Kg5! and there is no chance for white to win. More exactly, after 3..Kxh4; 4.Qh6 with double threat: the decisive 5.Qf4+ and the rook on d2 that is under attack; only now if 4..g5? then 5.g3+ Kxh3 (forced) and 6. Qxh5#; else if 4..R (anywhere) 5.Qf4+ Qg4 and white wins the queen and the game
I think that after the variation indicated by the second Anonymous starting with the 4th move, black can defend with 4.Rf2!; now if: 5.Qf4+ Qg4; 6.fxg4 Rxf4 and black wins; instead if 6.g3+ black can reply with 6..Kh3! threatning to mate on h2. The right continuation after 2..Kg5is 3.Nd5! and black has to deal with a zugzwang position.

The right continuation after 2..Kg5is 3.Nd5! and black has to deal with a zugzwang position.
correction again: as I said, after 4..Rf2 it follows 5.Qf4+ Qg4 then
6. Qh2+ and only at the 7th move white wins the queen and the game
Great comments, great ideas
1 Qg8+ Kh6
2 Qh8+ Kg5
Everybody agrees on that.
Now A) 3Nd5 3..Rd5!? not over yet
B) 3h4+! wins
3..Kf4 4Qh6+ and Rd2 will drop.
3..Kh4 4 Qh6! wins ( not 4 Nf5? as noted by one commenter ).
4Qh6! has multiple threats.
on 4..Rf2!? of course 5 Qh2+ wins
but I propose the neat
5 Nf5+!
The idea which didnt work on move 4 now works: 5..ef5 6 Qf4 #.
But that's not all, there's a C) variation left !
Can you spot it ?
