 | | Richard Taylor: On move 58. ... c3 also wins as does 58. Kf7
The computer gives in order of "bestness" so to speak: 1. 58. ... a4 as played about 5 points to Black. 2. Kf7 a little less and more then 3 points to 3. c3... (I went for that, I saw the initial c4 break, as this type of position always involves a pawn sac etc if there is a win or a draw). I think that Vorotnikov had this idea in mind a long time before they entered the ending. Otherwise he was mostly defending. Clever game by him to win. |

| | Richard Taylor: Round of applause for the oldfellers (not oddfellers!) Vorotnikov (a year older than I) became a GM when he was 58! A lot of players are fading away around then: maybe he had more time then for chess. |

| | Richard Taylor: < Cheapo by the Dozen: Chessvideos happens to have a puzzle today with a very similar theme:
http://www.chessvideos.tv/puzzle-38... >
Thanks for the link some nice puzzles on there! |
|
| Sep-04-14 | | Refused: Black is facing some problems on the king side. So we better get some passed pawn on the queen side. c4-a4-b3 seems to be the right idea.
57...c4
a)58.bxc4 a4 59.c5 a3 and so on and so forth
b) 58.dxc4 a4 59.c5 axb3 60.cxb3 d3 etc.
c) 58.Kh5 a4
c1)59.bxa4 b3 60.cxb3 cxd3 etc.
c2)59.Kg6 axb3 60.Kg7 bxc2 61.g5 c1Q 62.gxf6 Kd7 63.f7 Qg5+ In line c2) white can insert a capture but that won't change the bigger picture, that those Q-side pawns are too fast. |

| Sep-04-14 | | morfishine: <Richard Taylor> That has to be some kind of record, becoming a GM at age 58! I thought Ray Keene was pushing the envelope at 28! |

 | | perfidious: <morf> One should take into account those players who have won the World Senior title, several of whom have gained an automatic GM title for their victory: Vladimir Okhotnik was 61 when he won; Algimantas Butnorius also observed his sixty-first birthday the year he made gold, as did Larry Kaufman. |
|
| Sep-04-14 | | Marmot PFL: White is a pawn ahead and threatens g5 so black better do something- 57...c4 58 dc (58 bc a4) a4 59 ba b3 60 cb d3 and wins. If white doesn't play 58 dc, black continues a4 anyway (threatening a3), 58...a4 59 ba b3 60 cb cd and wins. |

 | | gawain: Instructive puzzle. And I enjoyed hearing about the players who were already "elderly" (like 58, a year older than I am) when they became GMs. |

 | | Sally Simpson: Something wrong with today's puzzle. No pieces were displayed.
Hopefully just a one day glich. |
|
| Sep-04-14 | | MarkFinan: Great game! Push the a pawn. Push the c pawn. Push the b pawn. And then the d pawn gets promoted. That's the easiest Thursday I've ever seen, but from the position on the front page there isn't too many options so that's probably why I found it so quickly. ✌ |
|
| Sep-04-14 | | morfishine: <perfidious> Fascinating! Facts that you present are highly interesting (at least to me) & illuminating! |

| | perfidious: On the POTD itself: the execution requires precision, but the underlying idea is fundamental, that of an overworked defender. |
|
| Sep-04-14 | | patzer2: <refused>...<c4-a4-b3 seems to be the right idea.>
Yes indeed! Take a "cab" to solve today's puzzle.
As <Gofer> observes there's no other option to gain the win and avoid the loss because < The move order is crucial. (57 ... a4 58 bxa4 c4 59 b3 loses for black!)>. This combo doesn't work on "ac" power. |
|
| Sep-04-14 | | MarkFinan: <perfidious: On the POTD itself: the execution requires precision, but the underlying idea is fundamental, that of an overworked defender> That's basically what I was trying to say, lol. They weren't many options so I found today pretty easy. |
|
| Sep-04-14 | | The Last Straw: One of the first Thursdays I've solved, but useful lesson anyway. |

 | | kevin86: With many pawns alone, being a pawn down is usually a death sentence. Black, however, finds a way to force a pawn home and win the game. Chessboard magic! |

 | | Jimfromprovidence: FWIW, this is the puzzle position with the white king on g3, black to move.
click for larger viewIt's lost for black. |
|
| Sep-04-14 | | tatarch: Looks like this idea really started with 53...f3+ or even 51...Qf7, if not earlier. 53...? black to move would be a solid weekend puzzle. |
|
| Sep-04-14 | | TheBish: R Tischbierek vs V Vorotnikov, 1979 Black to play (57...?) "Medium"
This is a pure pawn breakthrough problem.
57...c4! 58. Kg3
Or 58. bxc4 a4 followed by 59...a3 and the a-pawn queens, or 58. dxc4 a4 59. bxa4 b3 60. cxb3 d3 and the d-pawn queens. 58...a4 59. bxa4 b3 60. cxb3 c3 61. bxc3 dxc3 62. Kf2 c2 and the c-pawn queens. Interesting that a different pawn will queen for various replies. Bottom line is that the white king was too far away to defend. |
|
| Sep-04-14 | | dfcx: pawn ending!
only two choices for black a4 and c4.
57...a4 fails 58.bxa4 c4 59.b3! white wins
57...c4
A) 58.bxc4 a4 followed by a3 wins
click for larger view
B) 58.dxc4 a4 59.bxa4 (otherwise 60...a3 wins) d4 pawn will prompt
click for larger view
C) 58.c3 cxd3
D) 58.Kg3 or any other c3 59.bxc3 dxc3
click for larger view
white can' stop black pawns |

 | | doubledrooks: 57...c4! does the trick. For example:
a. 58.bxc4 a4 
b. 58.dxc4 a4 59.bxa4 b3 60.cxb3 d3 |
|

 | | Penguincw: Ooh. An endgame puzzle. I saw this type of puzzle before with 3 pawns, but that was long ago. |
|
| Sep-04-14 | | BOSTER: Before to push any pawn I look where is white
King, is he in the< square>? |
|
Sep-04-14
 | | FSR: 57...a4? 58.bxa4 c4 59.b3!  So instead <57...c4! 58.Kg3> (58.bxc4 a4 ; 58.dxc4 a4! 59.bxa4 b3! 60.cxb3 d3 ) <58...a4! 59.bxa4> (otherwise 59...a3 ) <59...b3! 60.cxb3 c3! and Black will, in the words of The Doors, <break on through to the other side>. |

| | Richard Taylor: <morfishine: <Richard Taylor> That has to be some kind of record, becoming a GM at age 58! I thought Ray Keene was pushing the envelope at 28! > Yes. I am just one year younger and I improved in 2010 due to quite some study and my rating was higher than when I was younger, although I think ratings are all inflated. But I was nowhere near IM strength or in fact any kind of title. I was a kind of "bunny, or Patzer, on heat"! But it is encouraging to see that the brain can keep working more or less even at my advanced state of decrepitude! Encouraging to see a fellow codger do well at such an advanced age... |
