Since, materially, black has an edge, it would appear to me that white should either be seeking a mating attack against the exposed black king, or find a draw by perpetual. A few first moves come to mind, starting with the most visually obvious:
Line A;
1. Qf3 Kh2 (Kh3 2. Qg3#) 2. Qg3 Kh1 3. Qf3 Kg1 (Kh2 draws, of course) 4. Qg3 Kf1 (Kh1=) 5. Qh3 Ke1 (Ke2 6. Qe3=) 6. Kc2 and now I think black is forced to accept the draw by perpetual. He can be endlessly harassed by the queen, and can no longer avoid by escaping through c5 or f5.
Line B;
1. Qh1 Kg4 2. Qe4 Kh3 3. Qf4 Kg2 (only move I see), and this reduces to the same as Line A above- a draw by repetition.
Line C;
1. Qf1 Kh4 and the king escapes through g5 winning the game for black, in my opinion.
Line D;
1. f3 Kh4 2. Qe1/d4 Kg5 and black should win.
Line E;
1. f4 Kh4 2. Qh1 Kg3 3. Qe4 Qd7 (king moves =) 4. Qe3 Kg4 and the king seems to escape through f5, g6.
The only other possibility I see for white is bring his king forward immediately to try for a mating net, but this seems to be a move or two short of effectiveness.
White must first triangulate for step one 1 Qh1+ Kg4 forced 2 Qe4+ Kh3 forced (the first phase is complete) 3 Qe6! the key move attacking the black queen.if black exchanges on e6 white is clearly winning,so the queen must escape but where? the only moves that dont result in the capture of the queen on a light square are Qf8 abd Qc7 and in either case 4 Qd6! renews the attack on the queen and threatens mate on g3 forcing black to exchange on d6 with a new white queen to follow.
1. Qh1+ Kg4 (forced) 2. Qe4+ Kh3 (again, forced) 3. Qe6 Qc7/Qf8 4. Qd6 threatening 5.Qg3# if the Q moves away, and if Black exchanges queen, White has an unstoppable passed pawn
I’m not sure what the delay is in entering your comment and when it gets posted? Anyway just in case my comments were lost I’ll reiterate. The key is an initial triangulation begining with 1 Qh1+ Kg4 forced 2 Qe4+ Kh3 again forced and then the key move 3 Qe6! with a check to the queen that forces either 3…Qf8 or ..Qc7. Then we get a repeating motif 4 Qd6! with a decisive check to the queen since the threat of mate on g3 forces a losing exchange on d6.
the idea is to use the mate threat on the g3 square. first I tried Qf3+ but I saw that the king can run away by h2 – g1. but suddenly Qh1+ came to my mind. now after Kg4 (forced) Qe4+ Kh3 (forced), Qe6 offers to exchange queens which results in an out of reach passed pawn for white. the only squares that black queen can run away to are f8 and c7. after Qf8 or Qc7, Qd6 offers the same exchange, but this time it’s forced because of the mate threat on g3. so, white wins!
Qd6 followed by Qg3 mate
Anonymous,
1. Qd6 Kg4 and the king escapes while black has a decisive edge.
How does Qf3 # followed by Qg3 not work??
White could escape with a perpetual starting with Qf3+.
Qg1
Since, materially, black has an edge, it would appear to me that white should either be seeking a mating attack against the exposed black king, or find a draw by perpetual. A few first moves come to mind, starting with the most visually obvious:
Line A;
1. Qf3 Kh2 (Kh3 2. Qg3#)
2. Qg3 Kh1
3. Qf3 Kg1 (Kh2 draws, of course)
4. Qg3 Kf1 (Kh1=)
5. Qh3 Ke1 (Ke2 6. Qe3=)
6. Kc2 and now I think black is forced to accept the draw by perpetual. He can be endlessly harassed by the queen, and can no longer avoid by escaping through c5 or f5.
Line B;
1. Qh1 Kg4
2. Qe4 Kh3

2. Qe1/d4 Kg5 and black should win.
Line E;

2. Qh1 Kg3
3. Qe4 Qd7 (king moves =)
4. Qe3 Kg4 and the king seems to escape through f5, g6.
The only other possibility I see for white is bring his king forward immediately to try for a mating net, but this seems to be a move or two short of effectiveness.
All in all, I favor line A taking the sure draw.
Oh, I forgot one line I meant to mention:
1. Qg1 Qc7 (only move)
2. Qh1 Kg4
3. Qg2 Kf5 should win for black.
If I am missing anything better for white, it is far too obvious or subtle for my skill level.:~)
This is pretty tricky..
Qg1 almost wins, but qc7 holds.
Qd6 seem not correct use to kg4.
Qf3+ kh2 qg3+ kh1 qh3+ kf1 then where the perpetual?
White has a draw after
1. Qh1+ Kg4 2. Qe4+ Kh3
and this can be thought of as a great achievement being two pawns down.
Will be pleasantly surprised if someone finds the win for White.
1.Qh1+ Kg4 2.Qe4+ Kh3 3.Qe6 Qc7(or f8) 4.Qd6 1-0
1.Qh1+ Kg4 2.Qe4+ Kh3 3.Qe6! Qf8 Forced
3.Qd6 +-
1. Qh1+ Kg4 2. Qe4+ Kh3 3. Qe6 Qf8 (c7) 4. Qd6! wins
Found it! 1.Qg1 Qc7 2.Qh1+ Kg4 3.f3+ Kf4 4.Qh2+ wins the Black Queen!

oops! Balck can take the pawn on f5….sorry….it was good for 30 seconds!

White must first triangulate for step one
1 Qh1+ Kg4 forced
2 Qe4+ Kh3 forced (the first phase is complete)
3 Qe6! the key move attacking the black queen.if black exchanges on e6 white is clearly winning,so the queen must escape but where? the only moves that dont result in the capture of the queen on a light square are Qf8 abd Qc7 and in either case 4 Qd6! renews the attack on the queen and threatens mate on g3 forcing black to exchange on d6 with a new white queen to follow.
Indeed, no one has come near the correct idea here. Think of a Queen hunt, not (yet) a King hunt!
Once you have the idea, the solution can be described briefly without a computer (I didn’t use one).
1.Qh1 Kg4 2.Qe4 Kh3
3.Qe6! Qf8/Qc7
4.Qd6! +-
nice
1. Qh1+ Kg4 (forced)
2. Qe4+ Kh3 (again, forced)
3. Qe6 Qc7/Qf8
4. Qd6 threatening 5.Qg3# if the Q moves away, and if Black exchanges queen, White has an unstoppable passed pawn

I’m not sure what the delay is in entering your comment and when it gets posted? Anyway just in case my comments were lost I’ll reiterate. The key is an initial triangulation begining with
1 Qh1+ Kg4 forced
2 Qe4+ Kh3 again forced and then the key move
3 Qe6! with a check to the queen that forces either
3…Qf8 or ..Qc7. Then we get a repeating motif
4 Qd6! with a decisive check to the queen since the threat of mate on g3 forces a losing exchange on d6.
1 qh1 kg4
2 qe4 kh3
3 qe6!! …
4 qd6 wins
1.Qh1 Kg4 2.Qe4 Kh3 3.Qe6 Qf8 (Qc7) 4.Qd6! (5.Qg3#) 4…Qd6 5.cd6 +-
the idea is to use the mate threat on the g3 square. first I tried Qf3+ but I saw that the king can run away by h2 – g1. but suddenly Qh1+ came to my mind. now after Kg4 (forced) Qe4+ Kh3 (forced), Qe6 offers to exchange queens which results in an out of reach passed pawn for white. the only squares that black queen can run away to are f8 and c7. after Qf8 or Qc7, Qd6 offers the same exchange, but this time it’s forced because of the mate threat on g3. so, white wins!
I thought a perpetual was the answer too. But after looking at comments I take another look and find this:
1 Qh1+ Kg4
2 Qe4+ Kh3
and now:
3 Qe6! Qc7 (or Qf8)
4 Qd6 threatening QxQ or mate on g3
5 … Qxd6
6 cxd6 and the d pawn queens.
Without superfluous black pawns 16 and c4, this is a study.
