| Dec-07-14 | | M.Hassan: "Insane"
White to play 22.?
White is a Knight ahead and his Queen is under attack22.Ne6+ Bxe6
23.Qd6+ Kg8
24.Qxc5 Bxc3
25.Bxe6 fxe6
26.Qc8+ Kh7
27.Qxe6 Qc7
28.Rh3
White is stronger
Also:
27..........Qa3
28.Qb3 Nd3++
29.Kb1 Qxb3
30.axb3 Nb4
31.Rd1
Again White is stronger |
|
| Dec-07-14 | | The17thPawn: 24. Bxe6 was my choice after the start of the sequence and given the game turned out drawn maybe its a better try? |
|
| Dec-07-14 | | diagonalley: <sjunto> me too!... and (as it's a sunday) i think we could reasonably award ourselves a quarter of a point! |
|
| Dec-07-14 | | patzer2: For today's Sunday puzzle solution, 22. Ne6+! (giving up the Knight for a discovered attack on the loose Rook/Bishop) is an obvious start. Where the combination gets difficult is finding stronger winning follow ups missed by White. Here's three missed opportunities:
(1) Instead of 25. Qc8+, 25. Ne6! Qxa2 26. Nf6+ Bxf6 27. Bxf6 Qa1+ 28. Kd2 Nc4+
29. Qxc4 Qxf6 30. Qxb3 Qxf4+ 31. Qe3 Qg4 32. g3  gives White a clearly decisive result. (2) Instead of 29. Qd7, 29. Rh3! wins immediately. (3) Instead of 30. fxg7  , 30. Rh3! is clearly decisive. |

| Dec-07-14 | | morfishine: I got three things right: (1) I guessed it was a Sicilian (2) <22.Ne6+> &
(3) 24.Qxc5
After that, forget about it
There are unumerable branches to ponder; for example should
White try to undercut Black's counter with 24.Bxe6 or is it better for Black to trade down with 26...Qxc3+ (instead of 26...Bxc3) or even try to interplolate 26...Nd3+ ? These stereotypical Sicilian complexities with their razor-sharp positions, are way too much for me this morning. With that said, I'll load it into a PGN viewer later and see if that simplifies anything ***** |
|
| Dec-07-14 | | Cheapo by the Dozen: White is up a piece at the moment. Black and White each have a knight hanging. Black also threatens to trap White's bishop. White's other (d4) knight is likely to hang in various lines too. 22 Kxb2 fails badly, to Qxc3+/Bxd4, with threats including the combination Bb4/Be3/Qxc2#. 22 Qd2 is harder to refute, but after ... Rxc3 material is even, the b2 knight is poisoned, ... f6 is threatened and so on. And Black can break the pin on his rook because of all the threats after ... Qa3. Other passive moves for White look pointless.
So let's consider 22 Ne6+, in response to which Black can either capture the knight or move his king. After 22 Ne6+ Bxe6/gxf6
23 Qd6+ Kg8
24 Qxc5 Bxc3
25 Bd8
it looks like White can simplify, and be the exchange up. Similarly, after 22 Ne6+ Ke8
23 Nxg7+ Kf8
24 Kxb2 Qxc3+
25 Kb1 Kxg7
White is a piece up in a reasonably safe position. That leaves 22 Ne6+ Kg8
23 Qxd7
White is two pieces up and also threatens mate starting with Qxf7+, a forced queen exchange with Qd8+, and Nxc5. I don't see how Black can survive. |
|
| Dec-07-14 | | Cheapo by the Dozen: I'm a more lenient grader than some, so I think several of us solved this puzzle. |
|
| Dec-07-14 | | gofer: Well, with black threatening Nxd1 and Qxc3, whatever white
does it needs to be quick. So I would guess that Ne6+ is about
as forthright as move can be...
<22 Ne6+ ...>
22 ... Kg8
23 Qxd7
22 ... fxe6
23 Qxd7 Qxc3 (Rc7 Qxe6 )
24 Qd8+ Kf7
25 Qe7+ Kg8
26 Qxe6+ Kh7
27 Qg8#
<22 ... Bxe6>
<23 Qd6+ Kg8>
<24 Qxc5 ...>
So we have won an exchange and extracated our queen, but are
we out of the woods yet???
<24 ... Bxb3!>
At this point, taking back the bishop looks like a mistake! 25 axb3 Bxc3 
25 cxb3 Nd3+
<25 Ne4! ...>

26 Nf6+
<25 ... Qxa2>
<26 Nf6+ Bxf6>

<29 Qxc4! >

Hmmm, well I got the first few moves, but now I am intrigued... Is <25 Ne4> any good? Does it deserve my impudent "!" or is it
garbage???
Okay all those with silicon buddies what do they say is the best
option after the cunning <24 ... Bxb3>... |
|
| Dec-07-14 | | GrandMaesterPycelle: I found the first few moves, though I did imagine white would win eventually |
|
Dec-07-14
 | | Penguincw: My neat jerk reaction was to play 22.Kxb2, but after 22...Qxc3+ 23.Kc1 Bxd4, all of a sudden, white went from being up a full piece to even material. |

| | skeptic50: Ummm -- nice 34-move combo to force the draw?? |
|
| Dec-07-14 | | patzer2: Correction to my previous post:
Instead of 25. Qc8+, White should try 25. Ne4! (diagram below)
click for larger viewNow, after 25. Ne4! (instead of 25. Qc8+), Black has nothing better than 25...Qxa2 when White gains a decisive advantage after 26.Nf6+! Bxf6 27.Bxf6 Qa1+ 28.Kd2 Nc4+ 29.Qxc4 Qxf6 30.Qxb3 Qxf4+ 31.Qe3 Qc4 (+3.92 @ 21 depth, Fritz 12 -- diagram below) 
click for larger viewHere, at the end of this 25. Ne4! line (diagram above), White wins easily. |
|
| Dec-07-14 | | patzer2: <skeptic50: Ummm -- nice 34-move combo to force the draw??> Maybe so, but it's only a draw because White missed several winning shots, such as 25. Ne4!, 29. Rh3! and 30. Rh3!, in the follow up to 22. Ne6+!! |

 | | Jimfromprovidence: <patzer2> <gofer> and others... 25 Ne4 threatens Nf6+ but 25...Qa6 stops that threat. 
click for larger view White has 26 axb3, which leads to 26...Qa1+ 27 Kd2 Qxh1. 
click for larger viewMaterial is even. Black threatens 28...Qxg2+.
White to play and win. |
|
| Dec-07-14 | | patzer2: <Jimfromprovidence> After 25. Ne4! Qa6 Qa1+ 27 Kd2 Qxh1 (last diagram in your post), White wins with 28. Qc8+! (28...Bf8 29. Be7! ) 28...Kh7 29. Nf6+ Bxf6 30. Bxf6 Qd1+ 31. Ke3! . |
|
| Dec-07-14 | | agb2002: White is one knight ahead.
Black threatens 22... Qxc3.
The black rook is defenseless. This invites to play 22.Ne6+, allowing Qd6+ with tempo: A) 22... Bxe6 23.Qd6+ Kg8 (23... Ke8 24.Qe7#) 24.Qxc5 A.1) 24... Bxc3 25.Bxe6 fxe6 26.Qc8+ Kh7 27.Qd7+ Kh8 (27... Bg7 28.Bf6 and mate soon) 28.Qd8+ Qxd8 29.Bxd8 + - [R vs N]. A.2) 24... Bxb3 25.Qc8+ (25.Kxb2 Qxa2+ 26.Kc1 Qxc2#; 25.cxb3 Nd3+ and 26... Nxc5; 25.Qxb5 Qxc3 26.axb3 (26.Qxb3 Nd3+ 27.Kd1 Nf2+) 26... Nd3+ 27.Qxd3 Qa1+ 28.Kd2 Qxh1) 25... Kh7 26.cxb3 Bxc3 27.Kb1 and White has the exchange but the king is not completely safe. B) 22... fxe6 23.Qxd7
B.1) 23... B(Q,R)xc3 24.Qe7+ Kg8 25.Qxe6+ and mate next. B.2) 23... Nc4 24.Qe7+ Kg8 25.Qxc5 Qxc3 (25... Bxc3 26.Bxc4 bxc4 27.Qxa5 + - [R]) 26.Bxc4 Qa1+ (26... bxc4 27.Rd1 + - [R]) 27.Kd2 Qxh1 28.Bxe6+ + - [B+P]. C) 22... Kg8 23.Nxc5
C.1) 23... Qxc3 24.Qxd7 Nd3+ (24... Qxc5 25.Qxf7+ Kh7(8) 26.Qg8#) 25.Qxd3 Qa1+ 26.Kd2 Qxh1 27.Qd5 wins. C.2) 23... Bxc3 24.Qxd7 looks similar to C.1.
C.3) 23... Bf5 24.Qd5 looks winning. |

| Dec-07-14 | | CHESSTTCAMPS: In this dynamic 2-way attacking position, white is a minor piece up, but has the less active rook. Apparently black has just snatched a pawn on b2, poking a hole in the white castled position with tempo. White acceptance of the pseudo-sacrifice gives back the material with dismal prospects: 22.Kxb2?? Qxc3+ 23.Kc1 (Ka3?? g4#) Qa1+ 24.Kd2 Qxd4+ 25.Kc1 (25.Ke2?? Bg4+ wins OR 25.Ke1? Qxd1+ 26.Kxd1 c6 traps white's dark squared bishop) 25... Qa1+ with at least a perpetual check and probably more. Attacking counterplay looks like the only option for white. At first I liked the idea of 22.Qe1(??) with the idea of 22.. Qxc3(??) 23.Qe7+ Kg8 24.Qxf7+ Kh7|h8 25.Qg8#. Then I noticed that 22...Nd3+ 23.cxd3 Qxc3+ 24.Qxc3 Rxc3+ followed by 25... Bxd4 appears to favor black. Interesting is the confusing 22.Qe2? Nd3+, but I much prefer a forcing simplification that activates the WQ. 22.Ne6+! sacs a knight for a tempo:
A. 22... Kg8? (Ke8?? 23.Nxg7+) 23.Qxd7 Qxc3 24.Nxc5 and black's attack is spent. B. 22... Bxe6 23.Qd6+ Kg8 (Ke8?? 24.Qe7#) 24.Qxc5 Qxc3 25.Qxc3 Bxc3 26.Bd8 and white's exchange should hold up easily with the Nb2 trapped. B.1 24... Bxc3 25.Bd8! Qxd8 26.Qxc3 Na4 27.Qh8+! and swaps queens into a won ending. Time to check.... |
|
| Dec-07-14 | | CHESSTTCAMPS: Not good - I missed the threats associated with 24... Bxb3 and failed to analyze it. |

| Dec-08-14 | | beonlychampion: I got QE2 and I think it wins too .throw some light |
