 | | luzhin: White's next move is 43.Nf5 trapping the Black Q. |

 | | NARC: Now I haven't looked things through, but there was a saying "castling into it" meaning castling into trouble, but here it seems black castled out of his party. |

 | | Phony Benoni: I'd say it's a Wednesday, simply because it's so misleading. If you see 43.Nf5 at once you're going to wonder why it's not an early Monday. If you don't spot the trap, you're probably going to go crazy trying to set up an Anastasia mate without allowing Black's queen a perpetual check. |

| Aug-31-11 | | lentil: 42. ... Kh8 43. Nf5 Ne2 44. Qa1!
42. ... Kf8 43. Nf5 Ne2 44. Qd1! |

 | | rhickma4: Although White is very cramped, you need to see that it is the Black Q which is trapped. 42.Ne7+ Kh8 43.Nf5 Ne2 Nxg3 44.Nxg1 Kxg1 45.fxg3 a4 and White has a simple win in the endgame |
|
| Aug-31-11 | | chesssantosh: A part of puzzle lies in realizing its white to move and win.i spent a couple of minutes trying to checkmate WHITE King |

 | | M.Hassan: "Medium/Easy" White to play 42.?
White is 2 pawns ahead.
Two movements of the Knight brings winning line:
42.Ne7+ Kh7
43.Nf5
And Black Queen is trapped now.The best thing would be to attack White Queen 43........Ne2
44.Nxg3 Nxg1
45.Kxg1 fxg3
46.a3
White can get g3 pawn as well. Will have pawn majority and wins.
This must be it. |

 | | Jimfromprovidence: White wins the queen no matter how black reponds to 42 Ne7+. If either 42...Kh8 or 42...Kh7, then 43 Nf5 attacks and wins the queen. The counterattack 43...Ne2 loses to 44 Qa1, threatening mate in one.

 | | sevenseaman: The Black Q looks to be in a bind. 42. N e7+ K~ 43. Nf5 puts it in boiling
hot water. Took me 3 good minutes to see it( all 3 in trying to find a mate).
But what a delight!
click for larger view<CG> , where did you find such a treasure? We must note any other dilly dallying by White could give Black a
a chance to draw via a perpetual. |

 | | dzechiel: White to move (42?). White is up two pawns. "Medium/Easy." When I first glanced at this position, I thought it must be black to move. I started looking at ideas like 42...Ne2 and was thinking that this might not be too difficult. Finally I actually read the text and saw that it was white to move instead. Well, the only "forcing" move that white has at his disposal is 42 Ne7+
The black king must move, say to...
42...Kh8
and now white gets to play
43 Nf5
Look at the black queen! "Checkmated" so to speak. Black's only try is to counter attack 43...Ne2
I don't see a way for white to both save his queen and cover f2 and e1 to prevent the escape of the black queen. But after 44 Nxg3 Nxg1 45 Kxg1 fxg3 46 a3 Be2 47 f4
Black will eventually lose the pawn on g3 and have to deal with the connected passers on the a- and b-files. There may be a fancier maneuver than this pedestrian line, but this should be good enough to win. Time to check. |

| | dzechiel: <lentil> points out the correct play after 43...Ne2, all depending on where the black king moved on move 42. Quite elegant. |
|
| Aug-31-11 | | LIFE Master AJ: 42.Ne7+ and Nf5 ... winning the BQ on g3. |
|
| Aug-31-11 | | LIFE Master AJ: There might be some counterplay after an eventaul ...Ne2; but it does not look to be enough. |
|
| Aug-31-11 | | LIFE Master AJ: <dzechiel> Good job on your post ... as usual! |
|
| Aug-31-11 | | ProjectR: Ne7+ ..Kh8/h7 then Qc5 looks playable with the threat of mate on h5..il take a longer look but i dont think this can be stopped,and black only gets one shot to check white i think.if im right its easy if im wrong its "insane" lol |
|
| Aug-31-11 | | fetonzio: of course instead of Qd1, Nxg3 wins easily too |

 | | Once: Fascinating. There is one winning move, but several possible continuations. Let's see if we can pull them all together: 42. Ne7+ is our key move, threatening the queen trap with 43. Nf5. Then we have two main choices to make - exchange down into an easily won endgame or win the black queen. The easy endgame method, suggested by <rhickma4>, <M.Hassan> and <dzechiel>, is to allow a mutual exchange of queens (after black chucks in the counter-attack Ne2). Then we win with our queenside zombie horde majority. Something like this:
42. Ne7+ Kh7 (in this line it doesn't really matter where the king goes) 43. Nf5 Ne2 44. Nxg3 Nxg1 45. Kxg1 fxg3 46. a4 
click for larger viewThe tide of undead cannot be stopped. Gruesome.
But there is a neater way to end the game. White can extricate his queen with a mate threat or a check and then snaffle the black queen with impunity. And it all depends on where the black king runs to. If he runs to h8 or h7, we play 44. Qa1 to threaten mate on g7: 42... Kh8 43. Nf5 Ne2 44. Qa1
click for larger viewBlack has to spend a move defending g7 (say with 44...f6). And that means that his queen gets murdered in the white cloisters. Nasty. Kudos to <lentil> and <Jim> for spotting that one. If the Black king runs to f8, we get a choice of finishes. After 42...Kf8 43. Nf5 Ne2 we get to here: 
click for larger viewAnd now white wins, either with <Jim's> 44. Qc5+ or <lentil's> 44. Qd1 threatening Qd8# Me? Today I was the materialist and planned only to swap off into the endgame. Can't resist an opportunity to start a zombie invasion. But I tip my metaphorical hat to those who spot the quicker wins. |

| | Once: <ProjectR> The problem with 42. Ne7+ Kh7 43. Qc5 is that black escapes with a draw. Black plays 43...Qe1+ leading to here:
click for larger viewNow 44. Kh2 Qg3+ and we are into a perpetual check. The white king can't escape. But this is white's best choice now, as the two other ways to escape check are worse. And if 44. Qg1 Qxe7. Black emerges a piece up and will quickly round up the white passed pawns. 44. Bf1 Qxf1+
This is a position where the white queen needs to stay on the back rank to prevent black from playing Qe1+. Hence the winning lines with Qd1 and Qa1. The one exception is Jim's Qc5+, but that works because it is check and black doesn't have time for Qe1+ |
|
Aug-31-11
 | | al wazir: 42. Ne7+ Ke8 (42...Kg8 43. Nf5 Ne2 44. Qa1) 43. Nf5 Ne2 44. Qd1, with a threat of mate. Black has to lose one of his royals. |
|
Aug-31-11
| | sevenseaman: The possibility of conceding Black a chance of perpetual ought to be a bigger worry than a milder counter by 43... Ne2. Nevertheless < lentil>'s comprehensive treatment < 42. ... Kh8 43. Nf5 Ne2 44. Qa1!
42. ... Kf8 43. Nf5 Ne2 44. Qd1!> of this latter aspect is laudable. |
|
Aug-31-11
| | al wazir: Correction: I meant 42. Ne7+ <Kf8> (42...<Kh8> 43. Nf5 Ne2 44. Qa1) 43. Nf5 Ne2 44. Qd1. |
|
Aug-31-11
 | | morfishine: <42.Ne7+> followed by <43.Nf5> and Black's Queen is trapped. A spin on the saying "Always check, it might be mate!"...Here, its "Always check, you may gather winning booty" |
|
Aug-31-11
| | sevenseaman: <morfishine>
<'Always check, it might be a mate'>, For a horse or a man its never too late,
A distant whinnying sound,
Or the telephone ringing around,
Always check it might be a date. |
|
| Aug-31-11 | | Willber G: <lentil: 42. ... Kh8 43. Nf5 Ne2 44. Qa1!
42. ... Kf8 43. Nf5 Ne2 44. Qd1!>
This does it for me, very neat. |
|
Aug-31-11
| | cocker: Surprisingly simple. After 43 ...  e2 White can either make a threatening move with his queen or simply go into the easily won endgame. |
