1 h7+ Kh8
2 Qxe6 Rxe6 (2 … fxe6 Nf7# or 2…Re7 3 Qxf7 Rxf7 4 Nxf7#)
3 Nxf7#
Checks are usually the most compelling. So I tried Bh7+ but can not find the win. Then I saw that h7+ is better because it does not lose the Bishop on h7. But I still can not find the win.
1.Qxe6 Re7
2.Qxf7+ Rxf7
3.h7+ Kh8
4.Nxf7#
1. Q:e6 wins because if ….fe or ….R:e6 2. h7+ Kh8 3. N:f7#.
1.Qxe6 Re7
2.Qxf7+ Rxf7
3.h7+ Kh8
4.Nxf7#
Qxe6!
After h7+ – Kh8, Qxe6 seems devastating. The Knight mates on f7.
Anonymous,
I did the exact same thing. LOL!!
Keep looking, is is obvious once you notice it!

I think I would play 1. Qxe6, the point being Rxe6 2. h7+ Kh8 3. Nxf7#. Here white could as well play h7 on the first move, but since black is not compelled to take the queen, it is better to keep h7 in the reserve.
After 1. Qxe6, black must defend the f7 pawn, but the only move I can think of is 1. …Re7. With the white queen thus better placed, the tactics on the kingside work out: 2. Bh7+ Kh8 3. hxg7+ Bxg7 4. Bxg7+ Kxg7 5. h6+ Kf8 (Kh8 6. Qf6#) 6. Qxe7 and 7. Qxf7#.
The point of the accuracy would be to choose the forced continuation after black’s reply to the first move, which adds a threat and enables the queen to participate in the attack.
If there is something quicker, I cannot see it.
Qxe6
Oh, but there is of course a mistake in 1. Qe6 Re7 2. Bh7+ Kh8 3. hxg7+ Bxg7 4. Bxg7+ Kxg7 5. h6+ Kf8 and the queen obviously cannot take the rook. Much better is 1. Qxe6 Re7 2. Bh7+ Kh8 3. Qxe7 Qa2 4. Qxf8+ Rxf8 5. hxg7#.
And for this to work, Qxe6 must come before a possible h7+
1.Qxd6 Re7
2.Qxf7+ Kh8
3.h7 Rxf7
4.Nxf7#
1) h7+ Kh8
2) Qxe6
with mate to follow when Nxf7
h7+, Kh8; QxB, R or p takes Q, Nf7++

Along the line shown by Michal G., perhaps 1. Qxe6 first is even more forcing since W retains the option of hxg7 as well as h7. Thus, if B plays 1. …. Re7; 2. Qxf7 Kh8;
3. hxg7 etc.
1.Qxe6+ threatening f7 pawn. If 1…RxQ, then 2. h7+ followed by Nxf7 mate.
Its a forced win. Seven moves is the longest black can survive.
1. h7+ Kh8 2. Qxe6 (Threatening Nxf7#) Re7 3. Qxe7 Qa2 4. Qxf7 +- Nxc2 5. Qxa2 Ne1+ 6. Kf1 Nxe3 7. Qg8#
Qxe6 fxe6
h7+ Kh8
Nf7#
This will hold good even if the Q sac is declined or RxQ
Hi Susan Polgar,
Ref : “Special chess tactic” [ White to move.
Sub : Lot of ways available for White to win but the most accurate to me is as given below,remember still in these given below moves variations exist but definite win assured for white in most shortest possible way.
1. h7+ Kh8
2. Q*Be6 [ R*Qe6/f7*Qe6 ]
3. Nf7+ mate
White wins the game : 1 – 0

Queen sacrifice … Qxe6! wins the game ..
1. Qxe6
1. Qxe6 … 2. h7+ … 3. Nf7 -+
Well, the h7+ leading to mate is very compelling indeed, but Susan wants the most accurate continuation – which I think is 1. Qxe6!! threatening 2. h7+ and 3. Nxf7#. Black needs to protect either h7 or f7. 1… gxh6 2. Qxf7# doesn’t work, so let us say she focuses on f7. 1… Re7? 2. Qf5!! and black’s toast again – 2… gxf6 3. Qh7#, 2… g6 3. h7# etc. It is a 3-move mate in all variations.
An immediate 1. h7+ takes much longer to checkmate, like:
1. h7+ Kh8
2. Qxe6 Re7
3. Qxe7 Qa2
4. Nxf7+ Qxf7
5. Qxf7 threatening mate next move (if the bishop stays put 6. Qg8#, and if it moves Qxg7#).
A fantastic exhibit on the power of two bishops attacking in tandem.
1.Qxe6 will do the trick for white.
1….fxe6 or Rxe6
2.h7+ Kh8
3.Nf7#
1….Re7 (protecting f7 pawn)
2.Qxf7+ Rxf7 (2….Kh8 3.Qg6 with Qh7 mate threat)
3.h7+ Kh8
4.Nxf7#
1….Qa2 lines is same as that for 1…Re7
Did I miss anything here?
How about Qxe6 first? Following up with h7+ and Bxg7+ and Qxg7# if Black does nothing.
mh, I cant see a difference between Qxe6 at first or playing h7+ immediatly. In the first case of course blackcan play gxh6, but after Qf6 it is as checkmate as possible …
Hopefully one of you higher skilled guys will check out the difference!
Could Black play Re7 after Qxe6 to stop White? What if White then plays Qxf7? The f8 Bishop cannot move anymore, then…
A Queen sac on e6 will win, because the defender bishop on e6 will by destroyd. After h7+ Kh8 follow’s by Nf7#

———–
Qxe6 first
If h7 and then Qxe6, then black can delay mate by playing f6
“Qxe6 first
If h7 and then Qxe6, then black can delay mate by playing f6″
In my opinion after f6 is Qg8 mate possible (however I have no beard at hand, so I am not totally sure)
1.Qe4! might also work 1-0
Sorry there is BD5! but still it should be winnig with h7+ and Qxd5 so effectively Qxe6 is much better!
This is one of those where you just have to see what is preventing mate. h7+ Kh8 the only thing stopping Nf7# is the bishop. Since the h pawn light squared bishop and knight are the only required pieces and the Be6 is the only defender Qxe6+ is easy 🙂
h7 Kh8 Qxe6 Qa2 Qxa2 Re7 Qxf7 Rxf7 Kxf7#. 1-0.
OR h7 Kh8 Qxe6 Re7 Qxe7 Qa2 Qxf7 Qxf7 Kxf7#. 1-0.
Hi Susan Polgar,
If Queen sacrifice is the initial move then win for white may extend for few other moves,if the Black is clever enough.
Here the puzzle comes alone with the caption [ give in most accurate move ].
So to curtail any manipulation of Black piece,the most accurate initial move will be as I have already given [ not only me,many others also given ] – h7+ ( Mate in 3 moves : Irrespective of Black’s any ambitious moves )
