Q:f6! g:f6 Ne7+ Kh8 B:f6#
1.Ne7+! Kh8 2.Qf6: wins at least a piece
Actually, Ne7+ first, since the B is pinned to g7, so Kh8 is required, then Q:f6+
Ne7 + Kh8
Qf6 gf6
Bf6
1. Ne7+ Kh8
2. QxB PxQ
3. Bf6#
Not sure if I actually submitted my last comment or not, so this might be a double.
Instead of Q:f6 to start, first play Ne7+ because the B is pinned to g7, so Kh8 has to be played. Then play Q:f6 winning the B.
At that point Rg8 has to be played or Q:b2 to stop the mate threat I think. If Rg8, then Q:f7 with threats of Q:g8# or Q:g7# if the R is moved. If Q:b2 then Q:b2 with massive material advantage.
At first I thought about Ne7+ (as the first move) THEN after Kh8 the Queen chops the B for mate to follow.
In Jerry’s idea, can’t Black play 2…Kg7 and escape?
I guess after Ne7+ Kh8 Q:f6, Black has the move Qg4 protecting the g7 square, but White has Bf3 attacking the Q. Black also has Nf5 after Ne7+ Kh8 Q:f6, protecting the g7 square and attacking the N on e7.
Fascinating position.
better to start with Ne7+
Jerry, why not Kg7 and Black wins?
Ne7+ is better. Bxe7 allows checkmate on g7 and Kh8 is answered by Qxf6.
Jerry.
1. Qf6 gxf6
2. Ne7 and then Kg7 and not Kh8
I think first is
1. Net Kh8
2. Qxf6 and at least white es a piece up
HT
Looking at Ne7+ Kh8 Q:f6 Nf5 some more.
After Nf5, N:f5 g:f6 B:f6+ Kg8 Nh6#
Better to play Ne7+ first. (In Jerry’s line, the black king can move to g7 instead of h8.)
I like:
1. Nf7+ Kh8 forced (or if BxN then Qg7#)
2. QxB winning the bishop.
Black can’t respond with gxQ since then Bxf#
Jerry,
2… Kg7 without mate.
Better the other way round:
1.Ne7+ Kh8
2.Qxf6! wins the exchange for white.
Ne7+ then Qf6
Jerry’s moves from 3:49 should be permutated a bit.
1. Qxf6??, gxf6 2. Ne7+, Kg7!
1. Ne7+!, Kh8 (Bxe7 2. Qg7#) 2. Qxf6 +-
Nice good night exercise (it is 0:24 a.m. here). 🙂
Best wishes

I don’t think posts are necessarily approved in the same time sequence as they are originally submitted – this causes a lot of confusion…
anyway, interesting position.
@Kerry, I think the comments are posted in the order they are submitted and approved. What makes it confusing is that the discussion is ongoing while they get approved in batches. So comments will be made without knowledge of what has already been said, but not approved.
Susan, thanks for posting this position. I worked on it this afternoon, and then set it up on a board as soon as I got home to look at it some more.
1. Ne7+ Kh8 (if …Bxe7 then 2. Qxg7#)
2. Qxf6 Rh7 (…Nf5 has already been analyzed )
3. Qxg7 Rxg7
4. Re8#
1.Ne7+ Kh8 2.Q:f6
A) 2..Nf5 3.N:f5 Qg4
A1) 4.Rc4 Nd7 5.Q:g7+ Q:g7 6.B:g7+ Kg8 7.Rg4 {Rybka liked 7.B:f8. I don’t think I visualized the reply of 7..e:f5 when I thought of 7.Rg4}
A2) 4.Q:f7! {Rybka’s line. I leave the rest for other readers to ponder.}
B) 2..Q:b2 3.Q:b2
C) 2..e5 {overlooked this response. following line is from a quick look with Rybka after I did my analysis of other Black responses} 3.B:e5 Qg4 4.Qd6 Re8 5.Rc8 R:c8 6.B:c8 Qd1+ 7.Q:d1 N:d1 8.Bg4
D) 2..Qg4 3.Qc3 {my earlier idea of Bf3 does not work and gives up the advantage that White gained because of N guarding g4 which will be able to guard f6 as well 3.Bf3?? g:f6 4.B:g4 N:g4 5.f3 Ne5 6.f4 Nd7} Nd7 4.Bf3 {now it works} Qg5 5.h4 Qf6 6.Q:f6 g:f6 7.f:e3 {white is up 2 pieces}
