Not easy to see the first move, at least for me it wasn’t. I first played with 1.Qh8 and 1.Bd1, but neither is good. However, while working through 1.Bd1 I realized I was being too cute with my plan, and that I should just open the line for the bishop immediately since it doesn’t matter whether or not black takes at f4- it is the mate at g5 with the queen that I missed the first time through, the simplest things sometimes are the hardest to spot:
1. f4! Qf4
White is threatening Qg5#, and the king has no escape on his own, and black must capture at f4, and capturing with the bishop is worse: [1. …Bf4 2.Bd1 Kh6 3.Qh8 Kg5 4.h4#]. Continuing:
2. Bd1 Kh6 3. Qh8 Kg5 4. h4 Qh4 (the point of 1. ..Qf4) 5. Qd8 and black will lose his queen to the skewer.
1. f4 forces Black to address the Qg5# threat and opens the d1-h5 diagonal for White’s bishop. Black can do nothing to prevent mate except lose a lot of material. 1. … Qxf4 2. Bd1+ Kh6 3. Qh8+ Kg5 4. h4+ Qxh4 5. Qd8+ Kf4 6. Qxh4+. (1. Qh8+ is thwarted by 1. … Bh6.)
1. f4 .. Qxf4 (or Bxf4 but with mate…) 2. Bf1+ .. Kh6 3. Qh8+ .. Kg5 4. h4+ (here would be mate if 1 .. Bxf4) .. Qxh4 5. Qd8+ .. Kf4 6. Qxh4+ eventually snatching all black pawns.
First I thought of a perpetual: Qh8 – Qd8 etc. that black doesn’t come out of (Kf4? Qh4). But as usual, I expect something better to exist, I suggest something with:
1. Be4 fxe4 (otherwise f4 Bxf4 Bf3+) 2. f4 Bxf4 (otherwise Qg5 or Qh8 mates) 3. h4 but this is not quite clear to me, though….
What a strange solution I gave in my first post:-) Be4 doesn’t seem correct here, better looks: 1. f4! This sack is magnetic due to the threat Qg5#, and black has no checks either. 1. … Qxf4 2. Bd1+ Kh6 3. Qh8+ Kg5 4. h4+ Qxh4 5. Qd8+ (the difficult one to see) catches the queen!
Rather difficult since you actually has to see the skewer on move 5, without this it runs into sand. But the 4 moves leading up to it are pretty simple though, the skewer became visible because I “wished strongly enough” that those moves should bring something…

I don’t see a good answer to 1.f4, threatening 2.Bd1#. Phil
1. f4 (threaten mate and also open the diagonal for the white bishop.)
Qh8+, Kg5
h4+, Kf4
Qb8+, Ke4
Qe5+, white wins
f4 wins the threats are qg5 and bd1
1. f4
if
1….. Qxf4
2. Qh8+ Kg5
3. h4+ Qxh4
4. Qd8+ Kh5
5. Bd1+
wins the queen
if
1. … Bxf4
2. Qh8+ Kg5
3. h4+ Kg4
4. Bd1#
Heh. Nice one. 1. f4!! blocks the bishop’s view of g5/h6, threatening Qg5#/Qh8#. Black has to take the pawn to stay in the game (he has no checks).
1. f4!! Qxf4 (1… Bxf4? 2. Bd1+ Kh6 3. Qh8+ Kg5 3. h4#)
2. Bd1+ Kh6
3. Qh8+ Kg5
4. h4+ Qxh4
5. Qd8+ and the black queen is dead.
1. f4 forces Black to address the Qg5# threat and opens the d1-h5 diagonal for White’s bishop. Black can do nothing to prevent mate except lose a lot of material. 1. … Qxf4 2. Bd1+ Kh6 3. Qh8+ Kg5 4. h4+ Qxh4 5. Qd8+ Kf4 6. Qxh4+. (1. Qh8+ is thwarted by 1. … Bh6.)
f4 is winning. Threaten Bd1 and Qh8 both.
Mustafiz
1.h4+ (Qg5#) Qxf4(Bxf4) 2.Bd1+ Kh6 3.Qh8#
1 f4 with idea of 2 Bd1+ and 3 Qh8#
f4! for white (forced mate in Bd1+ next!) no more solution for Black
ched8 cabe
1. f4 .. Qxf4 (or Bxf4 but with mate…)
2. Bf1+ .. Kh6
3. Qh8+ .. Kg5
4. h4+ (here would be mate if 1 .. Bxf4)
.. Qxh4
5. Qd8+ .. Kf4
6. Qxh4+
eventually snatching all black pawns.

Be4 doesn’t seem correct here, better looks:
1. f4!
This sack is magnetic due to the threat Qg5#, and black has no checks either.
1. … Qxf4
2. Bd1+ Kh6
3. Qh8+ Kg5
4. h4+ Qxh4
5. Qd8+ (the difficult one to see)
catches the queen!
1. f4, threatening both
2. Qg5#,
as well as
2. Bd1+ with
3. Qh8+ and
4. h4#
The threat of 1. f4 is actually not double, but triple: 2. Qg5#, 2. Qh8#, 2. Bd1+.
f4! Black cannot prevent the mate
1. f4 – Dxf4
2. Ld1+ – Kh6
3. Dh8+ – Kg5
4. h4+ – Dxh4
5. Dd8+ – Kh6
6. Dxh4
Hi Susan Polgar,
Well,okay puzzle.
White wins the game[ Variations exist ]
Example one
===========
1.Bd1 f4
2.h4 Q*h4
3.f4+ Kh6/Qg4
4.Qh8++ Mate
Example Two
===========
1.Bd1 Qf4
2.h4 Bc3
3.Qh8+ Qh6
4.f4+ K*h4
5.Q*Qh6++ Mate

I must be confused….but I only see f4….everything starts with f4.
I tried making Bd1 work but couldn’t. The best I can see is
1. Qh8+, Kg5
2. h4+, Qxh4
3. Qd8+, Kh5
4. Qxd2
1. Qh8+, Kg5
2. h4+, Kf4
3. Qb8+, Ke3
4. Qe5#,
Rather difficult since you actually has to see the skewer on move 5, without this it runs into sand. But the 4 moves leading up to it are pretty simple though, the skewer became visible because I “wished strongly enough” that those moves should bring something…
