StevieB: Qg5 then mate to follow.
Not mate for another 30 odd moves.
Black is in a hopeless position & has to lose material. |
|
Feb-11-14
 | | NM JRousselle: I don't think this is a very good puzzle. White has a crushing position with several moves that get the job done. Ne5 even has the threat of trading queens on a7 followed by a check on e7 and winning the exchange on c6. |
|
| Feb-11-14 | | morfishine: <29.Nxe5> Black cannot take the Queen due to 29...Qxe3 30.Ne7+ Kh8 (or 30...Kf8 31.Rxf7#) 31.Nxf7# Since 29...Qxe3 is not possible, what can Black do? It took me awhile to calculate that <29...Bc8> fails eventually: 29.Nxe5 Bc8 30.Qxa7 Rxa7 31.Nc6 Rad7 32.Nxd8 Rxd8 33.Rxc8 Rxc8 34.Ne7+Kf8 35.Nxc8 and White is up a Rook Since Black must clear the 7th rank but 29...Bc8 fails, where does Black's WSB go? Putting two and two together, <29...Bxd5> looks practically forced. The basic idea, (besides clearing the 7th rank), is due to all the forks looming [netting White a whole rook], Black might as well limit the damage to a minor piece (Hopefully!). <30.exd5 Qb7> not 30...Rxd5 31.Nc6 and Black goes down a whole Rook <31.Nc6 Rd7 32.Rce1> Threatening 33.Qxe8+ followed by mate. But Where does the Black Knight go? If 32...Nf6 33.Qg5 g6 34.Nh6+ followed by 35.Rxf6 or 35.Qxf6 with a crushing attack. 32...Nd6 is impossible due to 33.Nxd6 Rxd6 34.Qe8+ and mate next move. Neither the Queen nor Rook can play to the back rank due to the dominating White Knights. If 32...Kf8 33.Qg5 and again the d-pawn is taboo due to 33...Rxd5
34.Rxe8+ Kxe8 35.Nxg7+ Kf8 36.Ne6+ Ke8 37.Qxd5 fxe6 38.Qxe6+ Qe7 39.Qxe7# Since 32...Kf8 fails to 33.Qg5, Black is reduced to one move: 32...Nc7 <32...Nc7> Forced and arriving at a unique situation: Even with reduced material (down a piece), the remaining ones are getting in each other's way <33.Qg5 f6 34.Nce7+> And so Black loses a rook anyways prior to his position collapsing completely ***** |
|
| Feb-11-14 | | CC0112358: agb2002 A) line with the N fork is an excellent alternative where white gains material advantage and eventually wins. However, following the prescribed line of
29.Nxe5 QxQ 30.Ne7
to TheTamale's point, if
30....Kh8
then with black's Q on e3 and white's Q gone (black is +8 with -p -N +B +Q) white's mate is not obvious or imminent and black has a good fighting chance so long as he deploys his pieces from the 7 and 8 ranks. |

|
| Feb-11-14 | | PJs Studio: I looked at this for two minutes and was enamored by Nh6+, Nc5(yuck) and tactics against f7...then I realized the Nf5 check at e7 leaves the black king few squares. Then I remembered a mate of Ne7+ Kh8 Ne5xf7 mate. That's when I realized Nxe5 wins regardless. Tactical combinations are the life blood of chess.
Thanks to Chessgames.com for finding this Beautiful miniature. |

| Feb-11-14 | | kevin86: I like this one-a subtle queen sac on Tuesday-The main line is mate in two by a rook and knight or two knights, depending upon black's reply to Ne7. |
|
| Feb-11-14 | | gofer: I think this is a little bit more clear-cut than yesterday. Both Ne7+ and Nxd5 look to be winning pretty easily. 29 Ne7+ ...
29 ... Kh8
30 Nxd5 Nd6
31 Qxa7 Rxa7
32 Nc6 Bxc6
33 Nxc6 Raa8/Rad7
34 Nxd8 ... 
29 ... Kf8
30 Nxd5 Nf6/Nd6
31 Qxa7 Rxa7
32 N7c6 Bxc6
33 Nxc6 Raa8/Rad7
34 Nxd8 ...
So, as long as black doesn't fall for the queen sacrifice, white will simply be an exchange and a passed-pawn up... ~~~
Hmmmm... |

| Feb-11-14 | | BOSTER: Looking at the POTD I clearly see the picture where the great Petrosian being lost in reverie, looking at the undefended pawn in the centre ,
said:" I would take this pawn." |
|
| Feb-11-14 | | Tiggler: <mel gibson>:<Notice the best move is Q-g5 which is not the solution in the puzzle.> If the puzzle were: guess what white played, then Qg5 would not be the solution. But if the puzzle is find a sure win, then it is a solution, at least. And one does not need to consider another move after finding one that wins easily. |
|
| Feb-11-14 | | morfishine: <Tiggler> Good point, but thats the benefit: When a position is so weak that practically anything wins, then that encourages imagination |

| Feb-11-14 | | raycardenas: What if Black plays Bc8? |
|
| Feb-11-14 | | raycardenas: Sorry, first time poster. What if Black plays 29.....Bc8? It seems to cover the f7 square. |
|
| Feb-11-14 | | Cheapo by the Dozen: <raycardenas>,
After 29 ... Bc8, White goes straight to the c6 knight fork. That's the initial payoff against a variety of Black tries -- White snags the e-pawn and also gains the exchange with a fork at c6. |
|
| Feb-11-14 | | PJs Studio: No, black is mated regardless. After 29...Bc8: 30.Ne7+ still wins instantly. If 29...Kf8 Rxf7 mate. If 29...Kh8 then Nxf7mate |
|

|
| Feb-11-14 | | raycardenas: Cheapo, thanks for the help. PJs, after 30.Ne7+, QxNe7. White still has the c6 fork like Cheapo shows but Black gets two pieces for the rook and pawn instead of one. I look forward to getting help from all of you. |
|
| Feb-11-14 | | Granny O Doul: Since no one seems to have said it yet (except perhaps in the novel-length post I'm afraid I couldn't psych myself to read), the Nf5 defends the Qe3, so there is not even an apparent queen sac involved. Ne5, whatever else it does, captures an unprotected black pawn. |
|
| Feb-11-14 | | morfishine: <PJsStudio> Read the previous posts, <29...Bc8> is inadequate, but not for the reason you posted. The problem is: 29.Nxe5 <29...Bc8> 30.Qxa7 Rxa7 31.Nc6 Rad7 32.Nxd8 Rxd8 33.Rxc8 Rxc8 4.Ne7+Kf8 35.Nxc8 and White is up a Rook |
|
| Feb-11-14 | | devere: While 29.Nxe5 certainly wins, there is another rather pretty line that also works: 29.Qg5 f6 30.Rc7

|
| Feb-12-14 | | PJs Studio: Ooops. I posted and never thought to look more carefully. Easily seen over the board, but...much harder on an iPhone. In my defense, losing a whole rook or getting mated = same difference. |
|
| Feb-13-14 | | PJs Studio: To make up for my incredible oversight I will give the best responses after 29.Nxe5! 29... f6 30. Qa3 Nd6 31. Ne7+ Kf8 32. Qh3 Bxd5 33. Nxd5 Nxe4 34. Rc7 Qxc7 35. Nxc7 Ng5 36. Ne6+ Nxe6 37. Qxe6 Ra7 38. Nc6  Also! After 29...Bc8 (which is a lot better than I first thought) we missed 31. Nh6+!! putting the black king on a dead run. 31...gxh6 32. Rg1+ (Kh8? 33. Qg3 Bg4 34. Qxg4 Nf6 35. Qg7#) 32...Ng7 33. Rxg7+ Kxg7 34. Rg1+ Kf8 35. Qxh6+ Ke7 36. Nc6+ Kd7 37. Nxa7 Rxa7 38. e5 Kc7 39. Rc1+ Kd7 40. Qxh7 Ke7 41. Qh4+ Ke8 42. Qh8+ Kd7 43. Qh3+ Ke8 44. Rxc8 Rd7 45. d6 Ra7 46. e6 fxe6 47. Qxe6+ Kf8 48. Qf6+ Kg8 49. Qg6+ Kf8 50. Rxd8# Best I can do. |
