Mar-22-05 | | Karpova: how does white win after 44...nd6: ? |
|
Mar-22-05 | | aw1988: The knight simply returns, aids the pawn and the king captures black's only pawn, after which he may then promote. |

After 44...Nxd6 45. Nxd6+ is a win according to Nalimov tablebase (http://www.lokasoft.nl/uk/tbweb.htm, bookmark this page!)I haven't looked at the tables (except to confirm it's a win), but a win that's easily understandable for human players is: 44...Nxd6 45. Nxd6+ Kg6 46. Ne4 Kh5 47. Nf2 Kh4 48. h3! Kg3 49. Kd5. If 49...Kxf2, 50. h4 and the pawn queens, so now White's king is free to take care of the a-pawn. The tables may have faster wins. |

Mar-22-05 | | Sydro: 45.Nxd6+ 45...Kg6 46.Kd5
Not much black can do. White will use king to capture black's pawn and let knight protect white's pawn. |

Mar-22-05 | | Karpova: <aw1988> <beatgiant> thank you very much! |

Aug-24-05 | | Raskolnikov: Kmoch gives 9.♘f5 an exclamation mark, but I don't agree: black can play 9...♗:b5 e.g. 10.♕:d8 ♔:d8 11.♘:b5 ♘:e4 12.f3 a6! compare F Schubert vs G Marco, 1915. If 10.♘:b5 ♕a5+ 11.♘c3 ♘:e4 12.0-0 Black should not capture on c3 but simply develop his pieces. Further play of Rubinstein deserves (as usual ) study. |

Apr-10-08 | | Philidor: I don't get it. Black had several chances to draw! For God's sake, why didn't he just take the damn pawn on move 40? The only explanation is that he must have thought he could get the whole point - instead he didn't even get half of it! |
|
Apr-10-08 | | arnaud1959: <Philidor> White's plan is simple. The ♔ takes care of capturing the black ♙'s while the ♘ takes care of protecting the ♙ on f1 (or on g1 with the ♙ on h3 etc.) waiting for the ♔ coming back to help it. |

 | | Jimfromprovidence: Black could have saved his b pawn and most likely achieved a draw by 30...Kc7.  click for larger viewIf there is a clear path for white to win at this point, it escapes me. |
|
Apr-10-08 | | kevin86: An odd finish-for most of the ending,white is down a pawn-yet he still wins! |
|
Apr-10-08 | | Zorilla: If Black NxP ... then it is a Draw.
You can not mate with just a knight.
How is this a win for White? |
|
Apr-10-08 | | Zorilla: Disregard .... I didn't see the last pawn in the corner! |

Nov-28-09 | | WhiteRook48: 17 Bxc5 has pros and cons |
|
Dec-07-10 | | Rama: I disagreed right away with the note. You just know that black N is going to be a pest; it should die Bxc5. ♖ubinstein's mastery lay in maintaining control of the square in front of his pawn with the N while the K protects it. That's the reason for the exclam on move 33 and he does it again on move 42. In the final position the key is that white's K is within the queening square of the black Pawn, a8-a5-e5-e1. |
