I see Rf6 in about 5 seconds. Longer to be sure, however:
1. Rf6
Double threat- attacks the queen at c6 and threatens Rxh6 starting a mating net. Black has a few options- he can check from c7 with the queen, take the rook at f6, force white to take the queen at e6, or move the rook to c8. None of these can hold:
1. …..Qf6
2. Bf6 and black can’t even take the bishop due to Qh6#. Or
1. …..Qe6
2. Re6 fe6 with another loss. Or
1. …..Qc7
2. Bd6 Qd6 (nothing better)
3. Rd6 wins a queen for a bishop.
Finally….
1. …..Rc8
2. Rc6 wins easy too.
Bf6
1. Bf6 for if 1…Q:f3 2. Q:h6#
Rf6!
1.Rf6 Q is attacked as well as mate is threatened.Black has no time for kh7 or R moving out.
1…. Qc7+
2.Bd6 and wins
Rf6, Qxf6, Qxf6 wins
About 10 seconds to find the winning line. It is a lot easier to find the right continuation when you know for sure that there is a tactic to be found. I am sure that if this was an over the board game I was playing then it would take a whole lot more than 10 seconds to find if I found it at all.
1.Rf6 seems to completely disrupt black’s defence by interfering with the protection of the h6 pawn
if 1…gxf6 then 2.Qxh6#
if 1…Qxf6
2.Bxf6 Kh6 (2…gxf6 3.Qxh6#)
leaving white with a bishop and queen for a rook and 4 pawns. This position is winning for white because all he has to do is to set up a dark square blockade then forcefully win the a6 pawn and march the his own a pawn up the board.
if 1…Qc7+
2.Bd6 and black has to sacrifice te queen to avoid 3.Rxh6+ gxh6 4.Qxh6#
Bf6 with the intention of QxP. Seeing as Black cannot capture the rook because of the mate threat, black is completely lost.
Bf6 with the intention of QxP. There is no way to deflect this threat.
1. Rf6
–br
1. Rf6!
Now if 1…g7xf6
Then 2. Qxh6 mate.
Other moves lose material without necessarily stopping the mate.
For example
1…Qxf6
2. Bxf6 Re8
3. Qxh6+ Kg8
4. Qxg7 mate
Moving the Black Queen anywhere else to prevent 2. Rxc6 leads to
2. Rxh6+ g7xh6
3. Qxh6 mate
If 1…Qe4 to prevent the mate then 2. Qxe4 winning the Black Queen and the game.
1.Rf6!!! threatening queen and also Rxh6+
A-1….Qxf6.2.Bxf6. threatening Qxh6#
A1-2…gxf6.3.Qxh6#
A2-2…Kh7. white wins easily, up a queen and bishop vs knight.
B-1….Qc7+.2.Bd6.Qxd6+forced as otherwise Rxh6+ and Qxh6#.3.Rxd6 and white wins easily
C-1….Q-sixth rank.2.RxQ winning
D-1…gxf6.2.Qxh6#
D-1…g6..2.Qxh6#

It took me about 15 seconds to find a queen killer:
1. Rf6!
If now gxf6? then Qxh6#.
If queen moves out of 6th rank, then Rxh6+ gxh6 Qxh6#.
Or
1. … Qe4?
2. Qxe4 gxf6(?)
3. Bxf6+ Rg7
4. Qg4 any
5. Qxg7#
The only remaining option for black is:
1. … Qxf6(!)
2. Bxf6 Kh7 (to unpin g pawn)
Up with Q+B vs. R+4p.
But honestly I’m a bit unsure of the best continuation for white here!
Is this really a knock out?
I first thought this could be a playable practical choice:
3. Bxd4? cxd4
4. Qxd4 Re8!
Black’s plan here is to post rook on e6 and stay there to protect a6! (playing Rf6 if necessary)
Black will not launch any counter attack. But how can white advance here when he can’t take on a6?
Isn’t this a fortress?
So I rather try:
3. Qe4+ Kh8 (g6? Qb7 d3 Bc3)
4. Bh4 (only option, not Be7? Re8 Qb7 d3!) g5!
5. Bg3 Rd8!
6. Bf4! (f4? d3 looked bad) d3
7. Qb7 d2
8. Bxd2 Rxd2
9. b3! Rxf2
10. Kg3 Rb2
11. Qxa6 Rxb3
12. Qb6 c4
13. a6
I guess this is the winning line for white.
But I may of course have missed something.
Anyway, I’m sure white must find several accurate moves after the first one before calling this a knock out!
Looks like 1.Rf6 wins, but I can miss something.
In my previous post, I fell into the pitfall of making things too complicated. The simplest is often the best!
1. Rf8 Qxf8
2. Bxf8 Kh7
3. Be7!
The simplest of all moves, and black seems out of good answers here. both Ra8? and d3? fail to Qe4+. Also Kh8 Bxc5 is no good.
Or Re8 Bxc5 Re2 Bxd4.
3. … c4
4. Qe4+ Kh8
5. Qb7! c3 (desparation)
6. bxc3 d3 (dxc3 Ba3)
7. Qd7
Or:
5. … d3
6. Bb4 Rd8
7. Qxa6 d2
8. Bxd2 Rxd2
9. Qxb5
Looks like a “knock out”.
“It is a lot easier to find the right continuation when you know for sure that there is a tactic to be found. I am sure that if this was an over the board game I was playing then it would take a whole lot more than 10 seconds to find if I found it at all.”
Yes, this is very true for me as well most of the time. I have tried playing chess with the attitude that there is a tactic to find on every move, but with limited success.
Some have given 1.Bf6 as the answer but are missing the reply 1…Kh7, getting out of the pin as well as adding the King to the protection of h6.
Rf6 is stronger in part because it more fully demonstrates the principle of double attack. The rook attacks the Queen simultaneously with the attack on h6 so Black has no time for …Kh7
I liked that a couple readers pondered whether White had clearly won here after 1…Qxf6, 2. Bxf6 with the imbalance of material. I’m pretty sure White is but only after a little looking over… and I’m not sure I would find the most precise continuation.

Looking at the endgame Q+B vs R+ 4P after
1. Rf6 Qxf6
2. Bxf6 Kh7 simply Be7 looks strong
3. Be7 … The c-pawn is under attack. The d-pawn can’t run yet because Qe4+ wins it.
3… Rc8
4. Qf4… threatens to win the Rook with the fork Qf5+, also the c-pawn the same way. The d-pawn still can’t run and the f-pawn also under attack
4… Kg8
5.Qf5… simultaneously attacking the R and the c-pawn and still keeping the d-pawn immobile. I think this is clearly sufficient for White. –

The irony of the position is:
Black has 3 pawns for bishop, a good compensation.Black K has P cover whereas white K is in the open.
1.Bf6 does not work because of
1…Kh7 unpinning and all white can do is hope for a draw.
Black is probably completely winning because he has 4 pawns for the bishop and his center pawns should prove decisive.
“It is a lot easier to find the right continuation when you know for sure that there is a tactic to be found. I am sure that if this was an over the board game I was playing then it would take a whole lot more than 10 seconds to find if I found it at all.”
Yes, I like this comment, too, which Yancey Ward quoted. I think it may be helpful to some players to keep that in mind when looking at tactical problems like this and then to ask what are the elements that help them find the solution that they should be or could be aware of in normal play, when no one’s telling you for sure there’s a tactical breakthrough.
Here at least you can see the obvious idea of Qxh6 but of course it also seems clearly defended. 1) Bf6 is the wrong idea but nevertheless it at least hints at the vulnerability in Black’s defense. First, the g-pawn is overworked having to defend both the h6 pawn and the f6 square. Second, the protection of Black’s Queen to the defense of h6 can be disrupted (breaking communication).
As the Chernev/Reinfeld book Winning Chess stressed, tactical ideas do not have to come to us from inspiration out of nowhere; they are the result of methodical thinking as well.
