How much you want to bet that a bunch of these patzers here who claim 46 g4! is so obvious would have played 45 ... g7-g5?? just like GM Eingorn did? |

| Dec-20-06 | | Ch3ckmate: i dont really fully get it. i found the move but i dont see that it wins?...h takes g, then the idea is for the whites h pawn to move h5 eventually later promoting, but blacks king easily gets to block (and capture)that and there i dont just see advantadges for white. actually the position seems winning for black to me?is my calculating not thorough enough or is there something i cant see? can anyone explain? |

| Dec-20-06 | | chessmoron: <46. g4 hxg4 47. h5 Ke6 48. Kf2 Kf7 49. Kg3 Kg7 50. Kxg4 Kh6 51. Kf5 Kxh5 52. Kxf6 g4 53. e5 g3 54. e6 g2 55. e7 g1=Q 56. e8=Q+ Kh4 57. Qh8+ Kg3 58. Qg7+ Kh2 59. Qxg1+ Kxg1 is the best resistance line.> This is exactly where my line lies. The black king will be too late to capture the two white pawns whereas White king captures all the pawns and have one pawn of it's own. |
|
| Dec-20-06 | | DHW: Very instructive endgame the point is that Blacks pawn on f6 stops the Black King from getting to the h-file: 1.g4! hxg4
(1...gxh4 2.gxh5 h3 3.Kf2! the e-pawn can't be captured because the h-pawn would be unstoppable) 2.h5 Ke6 3. Kf2! Kf7 4.Kg3 Kg7 5.Kxg4 Kh6 6.Kf5! (White calculates that he is able to queen with check and force the promoted queens off whilst keeping his King more central and win on the QS:) 6...Kxh5 7.Kxf6 g4 8.e5 g3 9.e6 g2 10.e7 g1=Q 11.e8=Q+ Kh4 12.Qh8+ Kg3 13.Qg7+ Kh2 14.Qxg1+ Kxg1 15.Ke5 Kf2 16.Kd6 Ke3 17.Kc7 Kd3 18.Kb8 and the b-pawn will promote |

| Dec-20-06 | | rookending: Doesn't 44. ... f5 (instead of 44. ... h5) win for Black? |

I agree 46. g4! is the only good where as 45...g5?? is the only bad move. So both should be noticed OTB. |
|
| Dec-20-06 | | wharfrat: It's also important to see that 46...hg; 47.h5, f5; 48.h6 (48.ef, Kf5 wins for Black), f4+; 49.Kf2, Kf6; 50.e5+ (but not 50.h7, which loses)wins for White. There's a similar finale in a pawn ending in Chernev's book on Capablanca's endgames. |
|
| Dec-20-06 | | TantalumCarbide: This seems like an easy puzzle, since 46... hxg4 is met by 47.h5, and 46... gxh4 is met by 47.gxh5. Both ways win. |
|
| Dec-20-06 | | clausantos: Easy even for beginers. |
|
| Dec-20-06 | | sfm: The hardest puzzle for some time, unless one is satisfied with spotting the first move which is easy even for a beginner. BTW, Gypsy, where did you find the drawing for your "logo"? I know the artist, a Dane. The drawing (an excerpt) about 25 years old and made for the front page of a tournament folder. Very surprised to see it is still around. |
|
| Dec-20-06 | | ALEXIN: Easy puzzle may be. But difficult decision to take during a game. The main problem - I suppose- is that the f6 pawn is obstructing the black kings path. |
|
| Dec-20-06 | | DeepThought: g4 was the only plausible move..although I didn't see the whole win (but it is sufficient that Eingorn saw it :-)) |

The drawing (an excerpt) about 25 years old and made for the front page of a tournament folder. Very surprised to see it is still around. > Oh, this drawing is real big around here! It is <the famous dancing rook> which apeared around here first, unexpectedly and earily appropriately, in an animated form no less, at the end of the cg.com live broadcast of the game Leko vs Kramnik, 2004! Later cg.com made the drawing available as an avatar. I coveted it for some time before I adapted it with trepidations. I used to use another rook avatar before, but a one that was a bit square and brooding; and I did not want to be in danger of ever starting to take myself that seriously... Still, wearing this avatar felt a littlebit sacrireligious at first, but I got used to it. I still think it is an inspired little piece of artwork. My heart-felt thanks to the wizzard from Denmark that penned it; and I sincerely hope we are not violating copyrights! |

 | | Richard Taylor: <Rubenus: I saw the move immediately, like <Richard Taylor> and <spinal pat>. I thought: every other moves loses and 46. g4 is a typical puzzle move.> Yes - some things are easier - I looked at that Nimzovich win and missed the fairly obvious pawn check (but it was wonderfully played ending by Nimzovich) and I have gone wrong on many of these but sometiems Ise what is "obvious" (nothing is if you havent seen the idea before and that takes practice) - I still remember Reinfeld's book "Winning Chess" which helped me greatly when I was young and his injunction to examine all checks, threats, and captures and forcing moves - so nowadays I often look at the most unlikely moves first. I stil get caught out though - but g4 attacks a pawn and theatens to get Q - at first it looks as if Black will Q first but then I realised White can pick up Black pawn and the Black King cant get around his own pawns. |

that
46...hg; 47.h5, f5; 48.h6
(48.ef, Kf5 wins for Black),
f4+; 49.Kf2, Kf6; 50.e5+
(but not 50.h7, which loses)
wins for White.>
Very good!
I have to concede that I didn't calculate this all out - I saw the other lines above as lineated by <DHW>...hmm - the ending is not as easy as I thought - these endings are perfidious!! I would probably have - or might have played g4 but the g4 f5 line is hard to calculate. |

(Maybe easy for Kasparov or a very strong GM but not most players) |

 | | Peligroso Patzer: <knightfly: <Peligroso Patzer> White wins by 1.Kg2! Kxb5 2.f4 gxf4 3.g5 The plausible looking 1.Kg3 only draws to 1...Kxb5 2.f4 gxf4+ 3.Kxf4 fxg4> Correct solution. White must play what struck me as the paradoxical (because de-centralizing) 1. Kg2! so that after 2. f4, 2. ... gxf4 is NOT check, thus allowing 3. g5. |
|
| Dec-21-06 | | NBZ: I personally think 44. ... h5 isn't quite correct either, since it's good for black to maintain a pawn on g5 (to prevent the white king from penetrating to f4). So simply 44. ... g5 is simplest. Black probably only calculated the variations 45. Kf3 Kd4! and Black wins the e4 pawn; and 45. Kd3 gxh4 46. gxh4 Kf4 47. Kd4 Kg4 48. Kd5 Kxh4 49. Kc6 (Ke6? Kg5) Kg4! 50. Kb7 h4 51. Kxa7 h3 52. Kxb6 (a5 bxa5 53. b6 h2 54. b7 h1=Q 55. b8=Q Qxe4 might be the best try for white, but he's still two passed pawns down in a queen ending) h2 53. a5 h1=Q 54. a6 Qxe4 55. Ka7 (otherwise Qa8) Qe7+ 56. Kb6 (Ka8/b8 Qe8+ picks off the b5 pawn)f5 57. a7 Qe4! 58. Kc7 Qc4+ 59. Kb6 Qc8 60. Ka5 Qb7 and white's pawns are stymied. There are other possibilities for white after 52. Kxb6 h2, but I'm too tired to analyse them or start my computer engine. They do seem to be winning for Black. Perhaps Eingorn was so immersed in these variations that he simply overlooked 46. g4. This is where a bucket of cold water comes in handy. |

 | | Sneaky: <NotABanker> Of course you realize I was joking. Don't you? |
|
| Sep-12-08 | | Brown: Bizarre. The lesson on endgames at the end of "Chess Exam" by Khmelnitsky shows a position nearly identical; the only thing different being the exact placement of the Q-side pawns. |
