 | | Phony Benoni: Doesn't look like White is going to win this one by dominating the seventh rank. The sixth might be another matter. <32.Nh5+> comes to mind. If the knight isn't taken, king to a light square allows a fork and king to a dark square only delays that a move after Qxh6+. So <32...gxh5 33.Qxh6+ Kg8 34.e6 Bxe6 35.Rxe6> and hmmm, it's even material. White's position looks good, but is he smashing through, or just winning pawns as Black deals with the attacking threats? Not sure. |

| Mar-05-14 | | M.Hassan: "Medium/Easy"
White to play 32.?
Exactly the same material in both sides
32.e6 Bxe6
33.Nxe6+ Kg8
34.Qxh6 threatening mate on g7
34 .......Nc6
35.Qxg6+ Kh8
36.Rxc6!
White wins
Black may choose another path on move 32 as below:
32.e6 Qb5
33.Qa3 g5
34.Nxd5 Nxd5
35.exf7 Kxf7
36.Qd6! Rd7
37.Qe6+ Kg7
38.Qxh6+ Kf7
39.Qh7+ Kf8
40.Ra8+ Rd8
41.Rxd8+
and mate in couple of moves.
38.Qxh6+ Kf7 |

| Mar-05-14 | | patzer2: I took the quickest win I saw with the simple 32. e6! pawn fork. Both 32. e6! and the game continuation 32. Nh5+!! win. However, Fritz 12 @ 21/44 depth rates 32. Nh5+!! as stronger: 1.  (11.05): 32.Nh5+ gxh5 33.Qxh6+ Kg8 34.e6 Bxe6 35.Rxe6 Qxe6 36.Qxe6+ Kg7 37.Bxd5 Nxd5 38.Qxd5 Rf7 39.Qxc4 f4 40.gxf4 Rxf4 41.Qc7+ Rf7 42.Qe5+ Kg8 43.Qxh5 Kg7 44.Kg3 Re7 45.Qg5+ Kf8 46.h5 2. (5.87): 32.e6 Qb5 33.Ra8 Rb8 34.Rxb8 Qxb8 35.Qa3 Qe8 36.exf7 Qxf7 37.Qc5 g5 38.Nxd5 Ng6 39.h5 Nh8 40.Ne3 Qxh5+ 41.Kg1 f4 42.gxf4 Nf7 43.fxg5 |

| Mar-05-14 | | jrbleau: 32.e6 Qb5 and the win isn't straightforward.
32.Nh5+ gxh5 33.Qxh6+ Kg8 34.e6 Bxe6 35.Rxe6 seems forced and W is threatening RxN and then Bxd5. |
|
| Mar-05-14 | | diagonalley: well.. i saw the game line but the knight sacrifice didn't appear to be conclusive ... OTB i would definitely have gone with the immediate pawn fork... (a bird in the hand... etc) |
|
| Mar-05-14 | | morfishine: <32.e6> wins a piece and the game *****
PM: Black didn't play Al tha Bahadly

| Mar-05-14 | | zb2cr: Put me down with those who went with 32. e6. |
|
| Mar-05-14 | | gofer: Well the start is easy...
<32 Nh5+ ...>
33 ... Kf8/Kh8
34 Qxh6+ Ke8/Kg8
35 Nf6+
33 ... Kh7/Kg8
34 Nf6
<32 ... gxh5>
<33 Qxh6+ Kg8>
<34 e6 ...>
Now this is far from over but white's king is relatively safe but black's king is far from it! The real clincher is that white is threatening Ra8+ and exf7+. So white has no time to play Qe8 to try to get the queen on the
defensive side of its knight.
34 ... Qe8?
35 exf7+ Qxf7
36 Ra8+! Rb8
37 Rxb8+ Nc8
38 Rxc8+ Qe8
39 Rxe8+ Kf7
40 Rf8#
<34 ... Bxe6>
<35 Rxe6 ...>
click for larger viewBlack is in real trouble. The simplest threat that has to be countered is 36 Rxd7 Qxd7 37 Bxd5+ ... 35 ... Kf7
36 Rf6+ Ke8/Kg8
37 Rf8#
35 ... Qe8
36 Bxd5!
<35 ... Qd8>
<36 Rf6 ...>
click for larger viewIts all too horrible!
a) if the knight moves...
36 ... Nc8/Nc6
37 Bxd5+ mating
36 ... Ng6?
37 Rxg6+ mating
b) if the knight doesn't move...
36 ... Qe8?
37 Qg5+ Ng6
38 Rxg6+ Qxg6 (otherwise mate in 3 more)
39 Qxg6+
~~~
Yep. I am not surprised black resigned after <34 e6>! |
|
| Mar-05-14 | | morfishine: <gofer> Nice write up! Makes me sort of wish White didn't have another option |
|
| Mar-05-14 | | Cheapo by the Dozen: Direct material-attacking lines don't seem to work:
The g6 and d5 pawns seem well defended.
32 e6 seems effectively answered by ... Qb5.
Adding Rd6 into the mix doesn't seem to help much.
As for mating lines:
32 h5 doesn't seem to force any kind of response.
But 32 Nh5+ does. Specifically, 35 ... gxh5 is forced, as Black's king will otherwise be quickly driven to a light-colored square, at which point Nf6+ wins the queen. So that's what I'd play over the board, once I noticed that 32 Nh5+ gxh5
33 Qxh6+ Kg8
34 e6
allows White to win his sacrificed piece back, with even material and a ferocious attack. I'll see if I can circle back later and work through that attacking line to a clear win. |
|
| Mar-05-14 | | agb2002: The material is identical.
The first idea that comes to mind is 32.e6 Qb5 (else loses the bishop) 33.Ra8 Bg8 (33... g5 34.exf7 gxf4 35.f8=Q+ wins) 34.Qe3: A) 34... Rb8 35.Qe5+ Kh7 36.Rxb8 + - [R].
B) 34... Nc6 35.Nxd5 with an extra pawn and threatening e7. C) 34... g5 35.Qe5+ Kh7 36.Nxd5 Nxd5 37.Qxf5+ Kg7 38.Qe5+ Kg6 (38... Kh7 39.Be4#) 39.Rxg8+ and mate soon. -----
Another option is 32.Nh5+ gxh5 (32... Kf8 33.Qxh6+ Ke8 34.Nf6+ wins the queen; 32... Kg8(h7) 33.Nf6+ wins the queen; 32... Kh8 33.Qxh6+ Kg8 34.Nf6#) 33.Qxh6+ Kg8 34.e6: A) 34... Qb5 35.exf7+ Kxf7 36.Qxh5+ with a bishop and a pawn for a knight and attack. B) 34... Qc8 35.exf7+ Kxf7 36.Rf6+ Ke8 (36... Kg8 37.Qg5+ Ng6 38.Rxg6+ with an extra piece and a winning atack) 37.Rf8+ Kd7 38.Rxc8, etc. C) 34... Qd8 35.exf7+ looks similar to B.
D) 34... Qe8 35.exf7+ Kxf7 (35... Qxf7 36.Ra8+ wins) 36.Rf6+ Kg8 37.Qg5+ is similar to the subline in B. -----
I think I'd play 32.Nh5+. |

| Mar-05-14 | | Once: A surprisingly interesting puzzle. There are two things worth noting. First, 32. Nh5+ screams to be examined because it gives black so few choices in reply. Any move which restricts our opponent like this deserves at least a cursory look through. The point is that the black king can't run away without falling into a royal fork or allowing white to play Qxh6 followed by a royal fork. Then we have the analysis of the final position, or rather a couple of moves on from it. This is what we get after 34...Bxe6 35. Rxe6
click for larger viewMaterial is level but we own the sixth rank and the black king is mighty windy. The only slight problem is that it is black to move and try to set up a fortress. In other words, it's a GOOT position. Does black have a counterattacking move or a sound defensive move at his disposal? First we need to identify white's threats. And the threat that appeals most to me is Rf6. Let's say that we get to it after a pass move like 35...Qc7 36. Rf6 
click for larger viewThat seems pretty terminal. White threatens Rf8# and Qg5+/Wh6#. Black can't defend against both. So does black have a move that prevents Rf6 and all this carnage? 35...Qe8 allows 36. Bxd5 which can't be good for black. Everything else seems to be delaying the inevitable. Fritzie finds 35...f4 (which I hadn't spotted in honest mode) but it doesn't help after 36. Qg5+ followed by Qf6+ and gxf4. The interesting thing here is that the final position is level on material and it is black to move, but he's still busted. You just need to spot something like Rf6 at the end of it all to seal the win. |

I at last solved a Wednesday puzzle! |

36 Rxe7 Qxe7
37 Bxd5+ ...

 | | Penguincw: Took me a while to find 32.e6 (even though it wasn't the move played in the game), but at least it seems legit. |
|
Mar-05-14
 | | paulalbert: Got this one, but did spend a fair amount of time calculating. Looked at 32. e6 but liked 32. Nh5ch because after capture of the N to avoid Q fork, 33. Qxh6ch penetrates black's position nicely. Where I spent time was trying to find something more decisive than the 34. e6 fork, e.g., 34. Ra8ch but black can block the back rank, foiling any ideas at mate. Thought maybe my calculations had missed something, but looks like I was right for once. |
|
| Mar-05-14 | | Cheapo by the Dozen: OK. For an actual line, let's go with:
32 Nh5+ gxh5
33 Qxh6+ Kg8
34 e6 (Q moves somewhere generic)
35 exf7+ Kxf7 (forced)
36 Rf6+ Kg8/Ke8
37 Rf8#
The main alternatives I see for Black (other than those covered in my previous post) start with: 34 ... Qe8
35 exf7+ Qxf7
36 Rf6 Qg7/Qh7
37 Bxd5+ Nxd5 (diversion)
38 Rg6+
White wins the queen, and is up a couple of pawns a well. Less bad is 36 ... Qe8, but White is winning after 37 Re6 even so. |
|
| Mar-05-14 | | CC0112358: Material is even, but white's position is clearly superior. The 6th rank and the c1/h6 diagonal are key to white's attack. The e6 square is a battle spot. 32. e6 looks attractive. Also interesting is the f6 square which is defended only by the black K. Looks to me that clearing the c1/h6 diagonal to allow the white Q to attack the black K is key. So, best is A) 32. Nh5+ gxh5 33. Qh6+ Kg8 34. e6
Gotta go. Will look at the solution and Kibitz! later today. |
|
| Mar-05-14 | | mel gibson: I chose 32 e6 as my solution.
The computer chose 32 Nh5 - same as here.
However I tried both solutions on my computer the result was: 32 e6 mate by move 50.
32 Nh5 mate by move 57.
I had chosen the faster solution to checkmate.
White controls the center &
Black immediately loses a Bishop & a Queen.
Then a white Bishop can join in with the fun.
e6 was better.
Black was finished even though the material was even. |
|
| Mar-05-14 | | Ed Frank: I chose 32. Nh5+. It's a forcing move pushing the black king away from defense of the h6 pawn, allowing for the queen to invade say after 32...Kf8. The follow-up line: 33. Qxh6+, 33...Ke8, and 34. Nf6+ forking king and queen. This is no good for Black. Unfortunately, all other king moves after 32.Nh5+ besides 32...Kf8 leads to Black either getting mated or losing his queen. What remains is for the knight to be taken via 32...gxh5, meaning the queen swoops in with 33. Qxh6+ and king safety is still minimal while we're winning material anyways with 33. e6 after 32...Kg8. 32.Nh5+ is therefore crushing. |
|
| Mar-05-14 | | Once: <gofer> 35...Qc7 36. Rxe7 Qxe7 37. Bxd5+ Qf7 38. Bxf7+ Rxf7. White will win because he is queen for rook ahead. The nimbler queen will dance rings around the rook and hoover pawns. It's not an instant kill (it's hard to give mate when you've only got a queen in the attack), but white would have to do something very silly to lose (or allow a draw) from here. 36. Rf6 by contrast is mate in 5 (according to my silicon buddy). I actually thought it mated faster than that, but Herr Fritz prolongs the agony by throwing pieces away. The other drawback of the 36. Rxe7 threat is that black can counter it, say with 35...Qb5. Then white will need to look for another threat. And that might lead him back to ... 36. Rf6. The point behind Rf6 is that it creates unanswerable mate threats. Which means that you probably get to the pub faster than the Rxe7 line which ends up with a material plus but a bit of work to do before you can nail the coffin lid shut. Both lines win handily, so it's a bit of a moot point! |

| Mar-05-14 | | kevin86: Chess blindness: I missed the rook way over on the left coast. I did find the knight sac, but didn't know what to do with it. |
|
| Mar-05-14 | | Cheapo by the Dozen: I'll confess to not considering the simple 34 ... Bxe6 answer, but Black evidently didn't much like his prospects after it. Otherwise I nailed the problem. <gofer>'s analysis shows that the part I overlooked essentially transposes into the lines I did analyze. :) |
