White to move. How should white proceed?
I think this has been posted here before.
1. Qxf6+! Kxf6
2. Rxe6+ Qxe6 ( if…K moves, Rxc6)
3. Rxe6+ Kxe6
4. Bf5+ K any
5. Bxc8 +-
White captures on e6 three times followed by Bf5+ skewering the Rook.

1 Qxe6-Rxe6, 2 Rxe6-Rxe6, 3Qxe6-Rxe6, 4 Kxe6-Bf5#!, 5Kd5-Bxc8 maybe??? It’s the best movement i’ve seen so far, white finish with light square bishop, and black king become really passive since it has to defend either the pawns at the queenside and the one in d5. White gets slightly advantadge in material, and a really active game
1. Qxf6+ Kxf6
2. Rxe6+ Qxe6
3. Rxe6+ Kxe6
4. Bf5+ (After black king moves, Bxc8)
White wins.
1Qxr 2Rxb 3Rxq 4 Bishop skew wins.
1.Qf6+ Kxf6 2.Rxe6+ Qxe6 3.Rxe6+ Kg7 (If 3…Kxe6 4.Bf5+ wins the R on c8)4.Kf3 Rc3 5.Ke3 Rxa3 6.Re7+ Kf8 7.Rxb7 Ra4 8.Ra7 Rxb4 9.Rxa6 Rb2 10.Rxh6 Rg2 11.Rb6 Rxg4 12.Rxb5 Rg3+
13.Kd2 Rg2+ 14.Ke1 Kf7 15.Rxd5 Ke6 16.Re5+ Kd6 +/-
1.Qf6+, Kf6 2.Re6+, Qe6 3.Re6+, Ke6 4.Bf5 K__ 5.Bc8
I am strangely attracted to the “suicidal”:
1. Qxe6 Rxe6
2. Rxe6
Black is up with marerial, but how will he keep this advantage?
We can certainly exclude:
2. … Qxe6?
3. Rxe6 Kxe6
4. Bf5+! winning.
So it has to be:
2. … Qc7+
3. Kg2
and white has an extra move for defence, but there are also many white threats to defend against?
I am absolutely not sure about this:-)
If
1. Qxf6+ Kxf6
2. Rxe6+ Qxe6
3. Rxe6+ Kxe6
4. Bf5+ Kd6
5. Bxc8 Kc7
how does white win from there?
Credit should be given to the first one who solved the puzzle…Others more or less copy him…
The bishop skewer doesn’t win. Black just sits tight and White cannot penetrate.
Full credits goes to Yancey Ward, who had analysed the rather technical won ending after the Bishop skewer and by lack of time, had only suggered two other variations that I analysed later.
And no, Black can’t make any fortress at all.
Here are lines thrown the last time this position was submitted:
1. Qxf6+ Kxf6
2. Rxe6+! Qxe6
3. Rxe6+ Kxe6
4. Bxf5+ Kd6
5. Bxc8 Kc7
6. Bf5 Kc6
7. Kf3 Kc7
8. Ke3 Kc6
9. Kd3 Kc7
10.Kc3 Kc6
11.Kb3 Kc7
12.a4
and now three lines: 12…Kd6, 12…bxa4 and 12…Kc6
a)12…Kd6
13.axb5 axb5
14.Bg6
a1) 14…Kc6
15.Bf7 Kd6
16.Be8 and b5 will fall, and the white king will infiltrate the black position. Cutting the bishop off from e8 at move 14 won’t work either:
a2)14…Kd7
15.Bf7 Kc6 (Kd6 16.Be8+-)
16.Be8+ Kb6
17.Kc3 (waiting) Ka6
(17…h5 18.gxh5 g4 19.Bd7!) and the black pawn will be held up by Bh3 and the white h-pawn can’t be stopped].
18.Bf7 and the d pawn falls.
b)11… bxa4+
12. Kxa4 b6
13. Be6 Kc6
14. b5+!! axb5+
15. Kb4 Kd6
16. Bg8 Kc6
17. Bf7 one of the two pawn b5 or d5 falls, with win.
c)11… Kc6
12. Bd3 Kb6
13. axb5 axb5
14. Bg6 Kc7
15. Be8 Kb6
16. Kc3 Kc7 (16…Ka6 17. Bf7)
17. Bxb5 Kb6
18. Be8 Kc7
19. Bf7 Kc6
20. Kb3 Kd6
21. Ka4

Happy New Year!

1. Qf6+ leads to a final skewer of the king and Rc8 by the bishop. 1-0
“davey”: Are you kidding? After Bxc8, white gobbles up the queen side pawns. Black is helpless.
I would play Bf5 first. In any case black will loss pieces to white anyway. For those who suggested Qxf6 or Qxe6, please be aware that black doesn’t need to play Qxe6, instead black can counter-attack by playing qc7+!
1.Qxf6+ Kxf6
2.Rxe6+ Qxe6
3.Rxe6+ Kxe6
4.Bf5+ Kd6
5.Bxc8 1-0
Easy puzzle! 🙂
