|Jul-30-16|| ||HeMateMe: I think we're in best pun/worst pun territory, here.|
|Jul-30-16|| ||The Kings Domain: What castling could do...|
|Jul-30-16|| ||HeMateMe: I would dueck responsibility, were I you!|
|Jul-30-16|| ||RookFile: Black's play wasn't as bad as it turned out. I don't blame him for delaying castling. 12. Kh1 sends a message loud and clear that f4 and a kingside pawn storm was coming. Black felt under no obligation to castle into mate. His basic problem was he couldn't find a safe square for his knight.|
|Aug-01-16|| ||kevin86: White separates black's pieces and will mate soon.|
|Jul-23-17|| ||An Englishman: Good Evening: Already known, therefore finishing the week 6/6. Looking forward to Monday.|
|Jul-23-17|| ||ChessHigherCat: I guess we have to assume black can still castle. I instantly saw the "dream" variation (which assumes black is a total patzer):
26. Rfd1 Nxd1??? 27. Rxb8 Ke7/f7 28. Rb7 pins the queen, tadaa!
Now for the serious variations:
26. Rfd1 and the Queen has a fairly limited number of flight squares, and none at all that prevent Ba4+ (which is momentarily prevented by the knight).
If 26...Qe7/f7, 27. Qd4! wins the knight.
If 26...Qb7 offering a trade, 27. Qxe6+ can't be too healthy for black
If 26...Qc8, which looks like the best option, then...then...then we see why this is a Sunday puzzle. The only way to keep black from castling (without loss of material) would be 27. Rd6 and if e5 then Qd5 would prevent castling and allow the bishop to penetrate on f5.
Now for the fun part, let's see how completely wrong we were!
|Jul-23-17|| ||ChessHigherCat: Well the solution was slightly different so I'll only give myself 99% credit today, since nobody is looking. Just kidding, missed it totally.|
|Jul-23-17|| ||piltdown man: Found it. Quite easy, really.|
|Jul-23-17|| ||al wazir: <26. Ba4 Qxa4 27. Qxe6+> Kf8. Now what?|
If 28. Qd6+, then 28...Kg7. If 28. Rxf6+, then 28...gxf6 29. Qxf6+ Kg8 29. Rf1 Qe8 30. Rf3 Qg6 31. Rg3 Qxg3 32. hxg3.
|Jul-23-17|| ||diagonalley: "insane"(?).... nope... cute, but no way insane|
|Jul-23-17|| ||piltdown man: Yes, much too easy for a Sunday.|
|Jul-23-17|| ||Iwer Sonsch: As a patzer, I would play 26.Rxb2 Rxb2 27.Ba4 Qxa4 28.Qa8+ K any 29.Qxh8 and try to grab some pawns. Let's see what is even better.|
|Jul-23-17|| ||Iwer Sonsch: Okay, I don't see the win after 29...Qxc4 30.Rc5+ Qxc5 31.Qxc5+ Kd7.|
|Jul-23-17|| ||patzer2: Today's Sunday puzzle includes a considerable number of side variations and mates in the heavy piece Queen and Rook King Hunt that follows after the game-winning solution 26. Ba6!! |
I found the initial move, but after a bit of calculation got lost in some of the complications which follow.
It gets particularly complicated in the line not played after 27...Kf8, when the continuation of the mating attack requires a second sacrifice with 27...Kf8 28. Rxf6+! leading to mate-in-13 in a maze of variations with the remaining Rook and Queen.
Also, in the game continuation after 27...Kd8 28. Qd6+ Kc8, it seems to me that it was not so easy for White to find the best move 29. Rf5! (forcing mate-in-17 per Stockfish 8.)
P.S.: Black's decisive error appears to be 17...Qxe5? allowing 18. Qd2! to . Instead, Stockfish 8 indicates Black can put up much more resistance and secure drawing chances with 17...Bxe4 = to -
Earlier, I was surprised to see Stockfish 8 indicate that castling into the relatively unprotected King-side with 16...0-0 = holds it fully level. As such, I suppose 16...0-0 = is preferable to 16...b5 17. Ne4 .
|Jul-23-17|| ||malt: Got 26.Ba4 deflecting,...Q:a4 26.Q:e6+ Kf8 27.R:f6+ (27.Qd6+ Kf7 28.Qc7+ Kg6 Qg3+ Kf7= )27...gf6 28.Q:f6+ Kg8 29.Qg5+ Kf7 30.Rf1+ Ke8 31.Qe5+ Kd7 32.Rf7+ Kd6 33.Rc7# 26.Q:e6+ Kd8 27.Qd6+ Kc8|
|Jul-23-17|| ||TheFocus: More like a Monday puzzle than a Sunday one. Too easy.|
|Jul-23-17|| ||malt: My earlier post Q:e6+ should have been move 27.
After 29.Rf5 what would be blacks best defence ? 29...Qd7, 29...Rb4|
|Jul-23-17|| ||ChessHigherCat: Funny how the people who brag about getting these puzzles easily absolutely never indicate the possible variations, probably because they only calculated 5% of them.|
|Jul-23-17|| ||agb2002: White has a bishop for a knight and a pawn.
The black queen prevents Qxe6+ and the knight is pinned. These details suggest 26.Ba4 Qxa4 (26... Nxa4 27.Rxb8+ wins) 27.Qxe6+:
A) 27... Kd8 28.Qd6+ Kc8 29.Rf5
A.1) 29... Nd3 30.Rxb8#.
A.2) 29... Qb4 30.Rc5+
A.2.a) 30... Kb7 31.Rc7+ Ka8 32.Qxa6#.
A.2.b) 30... Qxc5 31.Qxc5+ Kd7 (31... Kb7 32.Rxb2+ wins) 32.Qd4+
A.2.b.i) 32... Kc7 33.Rxb2 Rhd8 34.Qa7+ Kc6 35.Rb6+ wins.
A.2.b.ii) 32... Kc6 32.Rxb2 Rhd8 33.Rb6+ Kc7 34.Qc5+ Kd7 35.Rxb8 wins.
A.2.b.iii) 32... Ke6(7) 32.Rxb2 Rhd8 33.Re2+ Kf7 34.Qa1 + - [Q vs r].
A.3) 29... Rd8 30.Rc5+ as in A.2.a.
B) 27... Kf8 28.Rxf6+ gxf6 29.Qxf6+ Kg8 30.Qg5+
B.1) 30... Kf7 31.Rf1+
B.1.a) 31... Ke8 32.Qe5+ Kd7 33.Rf7+ and mate in two.
B.1.b) 31... Ke6 32.Qd5+ Ke7+ 33.Rf7+ and mate in three.
B.2) 30... Kf8 31.Rf1+ transposes to B.1.a.
|Jul-23-17|| ||malt: <ChessHigherCat> Yes I had noticed.|
|Jul-23-17|| ||drollere: the B skewer on a4 and forced Q capture, freeing Qxe6+, leaped to view immediately; i got the lead moves after a 30 second inspection. after that, the open files make the crush inevitable.|
|Jul-23-17|| ||Jimfromprovidence: I did not find the elegant solution 29 Rf5 but I think 29 Qc5+, seeing 29..Kd8 30 Qa7 does win material.|

It's interesting because if black does play 30...Kc8, then 31 Rf5 now seems much easier to spot to me than two moves earlier.

|Jul-23-17|| ||wtpy: I barely considered 27.. Kd8; saw pretty quickly that if Kf8 Rf6+ had to be crushing. White checks with the queen until he drives the black king to an open file.|
|Jul-24-17|| ||Howard: 26.Ba4 was probably what patzer2 meant---"26.Ba6" is obviously impossible.|
