| Oct-01-06 | | bakuazer: i got this very quick. Not a difficult puzzle at all. Impossible not to notice 63.d6 after that 63...Nf6 is forced, and then 64.Nxd5 followed by 65.b4 is quite a standard idea, those with little experience know that black knight is helpless against a5 and d6 pawns. In the rest one needs to be just a little bit careful, like 79.d8=Q would lead to a perpetual check. |

| Oct-01-06 | | chessmoron: Solution my puzzle:
Black wins material with 1 … Nd2, as 2 d6 Rxd1 3 d7 permits 3 … Nf3+! 4 gxf3 Rxf2+ 5 Kh3 Rh1 mate. Full game: R Sagit vs T Hillarp Persson, 2006 |
|
| Oct-01-06 | | RandomVisitor: Did Alburt blow it with 74.d7? Possibly 74...Qa4+ leads to a draw. Winning for white was 74.Qd3+. |

No, I don't think so. 74...Qa4+ 75.Kc1
Qa3+ (75.. b3 76.Qc3+ ) 76.Kd1 Qf3+ 77.Kc2! Qe4+(or Qf5+) 78.Qd3+ |

| Oct-01-06 | | GREATOTBCHAMP: This was so easy, I think monday! |
|
| Oct-01-06 | | vibes43: I chose obvious first moves but didn't expect the white knight sac. Can't say I solved but very instructive for me. |
|
| Oct-01-06 | | greensfield: Can Black get any better counter play with pushing e pawn a move earlier 65...e4 |
|
| Oct-01-06 | | TrueBlue: got it, easy one. |
|
| Oct-01-06 | | Parriotblue: Can someone tell me how White wins after 63...Nxd6,64.Nxd6 Kd2? |
|
| Oct-01-06 | | greensfield: <Parriotblue: Can someone tell me how White wins after 63...Nxd6,64.Nxd6 Kd2?> Is 64...Kd2 legal? |
|
| Oct-01-06 | | ex0duz: Parriotblue, Kd2 is an illegal move..
If you meant Kf2, then i would reply with 65. Kd3, and so on with plans to take the e pawn, and then the weak b6 pawn. Greensfield, i'm guessing no, since white will queen first, and then probably the same ending will happen anyway.. QQ v Q :) |
|
| Oct-01-06 | | ex0duz: Parriot.. If its still unclear,its just a simple matter of using your extra minor piece(horse) and making it into a zugzwang(sp?) position. The d6 horse will stop any potential e4 break. |
|
| Oct-01-06 | | vesivialvy93: Alburt .....or Karpov ? nice and clear ending !!! |

 | | al wazir: I got the first three moves (63. d6 Nf6 64. Nxc5 bxc5 65. b4) At that point Black can capture with either 65...axb4, as in the game, or 65...cxb4. The sequels in the two lines are totally different. A complete solution would have to deal with both. The game lasted another 15 moves. I don't see that the moves made are all forced or even the best choices. I doubt if Alburt visualized the entire thing before playing 64. Nxc5. I am absolutely certain that no one posting to this site did. If I had been playing OTB, would I have given up a sure draw in this position for the chance of a win? I don't know. It depends on the stakes. Anyone claiming to have "solved" this is stretching the truth. |

65...cxb4 is significantly easier. what is the strongest defense you propose black may have in this case?
the "15 moves" are about advancnig d6 pawn. moves are not completely forced, but it is a usual business. |

| Oct-01-06 | | Sydro: <greensfield:<Can Black get any better counter play with pushing e pawn a move earlier 65...e4>> This is the computers suggestion: 65...e4 66.bxc5 Kf3 67.c6 e3 68.d7 Nxd7 69.cxd7 e2 70.d8=Q e1=Q 71.Qd5+ Whites position is winning.

Thanks your diagram makes it clear |

| Oct-01-06 | | NakoSonorense: I AM NOT KIDDING! I saw the first 8-9 moves in less than 20 seconds!!! OMG, I'm so goooood... |

| Oct-01-06 | | blakjak: woo i got it |
|
| Oct-02-06 | | Parriotblue: <exOduz> Sorry, I mean 64.. Ke2. Thanks for analises. |

 | | kevin86: I figured that a knight sac would force a breakthrough,but I didn't see how:( |
|
| Jun-13-08 | | Timothy Glenn Forney: Silman's analysis of this endgame is amazing. |
|
| Jul-09-12 | | vinidivici: 64.Nxc5!
This sacrifice explanation is listed at the Endgame Manual by Dvoretsky. And there is a trap if white 79. d8=Q then, it is a draw,, with perpetual check beginning with 79.Qf3+ |

 | | FSR: <vinidivici: ... And there is a trap if white 79. d8=Q then, it is a draw,, with perpetual check beginning with 79.Qf3+> Yes! This surprised me; I could easily imagine falling into this. 79.d8(Q)?? Qf3+ 80.Ke1 Qh1+ 81.Kf2 Qh2+! 82.Ke3 (82.Kf1 Qh1+) Qf4+ 83.Kd3 (the only winning try; other moves repeat) Qf5+! 84.Ke2▢ (84.Ke3?? Qf3#) Qf3+ with perpetual check. |
