Nov-12-21		raymondhow: My first Friday solve in a while. First move 20.Rxe6 was chosen pretty much on faith since it was a puzzle; not sure I'd have the guts to play it over the board. Sacrificing the other R didn't come to me right away, till I saw the K could be chased to the middle of the board. Instead of 26.h4+ at the end I chose 26.Be7+ which is also mate in two.

Nov-12-21		saturn2: Found 20.Rxe6 and blacks defence Re8 which is not enough. Accepting 20...Kxe6 leads to desaster. 21.Re1+ for instance 21....Ne5 22. Qg4+ f5 23. Rxe5

Nov-12-21		stacase: I missed 21.Re1+ I would have moved 21.Qg4+ probably followed with 22.Re1+ depending on what Black does. If Black moves 21...Kf7 then ???

Nov-12-21		raymondhow: < Accepting 20...Kxe6 leads to desaster. 21.Re1+ for instance 21....Ne5 22. Qg4+ f5 23. Rxe5 > 22.Qg4+ doesn't work, Kf7 holds. Apparently both rooks must be sac'd.

Nov-12-21		vajeer: A bit easy for Friday. There is not much branching and many moves are forced.

Nov-12-21		Diademas: I got this at first attempt. I'm either getting better or luckier.

Nov-12-21		Knightf7mate: Wow. A double rook sacrifice. One I could see. The second was beyond me.

Nov-12-21		drollere: the obvious (to me) entry is 20. Rxe6 Kxe6, 21. Re1+, after which retreat of the K allows a variety of mating incursions with R and Q, aided by B discovered checks, and 21. .. Ne5 allows 22. Rxe5 and 23. Qe7+ with more mates on menu. i did not look at declining the sacrifice.

Nov-12-21		JohnBoy: I asked the same thing, <stacase>. But 21...Kf7 22.Re7+ either ♔g8 23.♕c4+ or ♔f8 23.♕h5 does the job. In the second case the mate 23...Qd5 24.Re8# is nice.

Nov-12-21		agb2002: White has a bishop and a pawn for a knight. Black threatens Nxc5. The only defender of the pawn on e6 is the black king. This suggests 20.Rxe6: A) 20... Kxe6 21.Re7+ A.1) 21... Kf7 22.Re7+ Kf8 (22... Kg6 23.Qg4+ Kh6 24.Qxg7+ Kh5 25.Qg4+ Kh6 26.Bf4#; 22... Kg8 23.Qc4+ and mate in two) 23.Rxd7+ Ke8 24.Rc7 wins decisive material (24... Qd5 25.Qb5+ and mate in two; 24... Qb5 25.Qe4+ and mate next). A.2) 21... Ne5 22.Rxe5+ fxe5 (22... Kf7 23.Re7+ as in A.1) 23.Qe7+ Kf5 (23... Kd5 24.Qf7#) 24.Qxe5+ Kg6 25.Qe6+ Kg5 (25... Kh5 26.Qg4+ Kh6 27.Bf4+ g5 28.Qxg5#) 26.h4+ (26.Be7+ Kf4 27.Qxc6 just wins decisive material) 26... Kf4 (26... Kxh4 27.Qg4#; 26... Kh5 27.Qg4+ Kh6 28.Qg5#) 27.Qf7#. A.3) 21... Kd5 22.Qe4#. A.4) 21... Kf5 22.Qg4#. B) 20... Nxc5 21.Re7+ as in A.1. C) 20... Rae8 21.Rxe8 C.1) 21... Rxe8 22.Qh5+ g6 (else 23.Qxe8+) 23.Qxh7+ Ke6 24.Re1+ Ne5 25.Bxe5 fxe5 26.Qxg6+ wins decisive material. C.2) 21... Kxe8 22.Re1+ (22.Qe4+ Qxe4 23.fxe4 bxc5 24.Bxc5 with a favorable ending: 24... Nxc5 25.Rb8+ wins the exchange) 22... Kd8 23.Be7+ Kc7(8) 24.cxb6 looks good for White. D) 20... Ne5 21.Rxe5 fxe5 22.Qe7+ Kg6 (22... Kg8 23.Qe6#) 23.Qe6+ transposes to A.2.

Nov-12-21		devere: A very nice combination. Not that hard to see, but very nice anyway.

Nov-12-21		carpovius: 21.Qc4+ instead of 21.Re1+ wins immediately

Nov-12-21		King.Arthur.Brazil: <carpovius> I don't think so: 21. ♕c4+ ♕d5 22. ♖e1+ ♘e5 what else?
