 | | chancho: Giri must know it's drawn. He's still plugging away though.. |
 |

 | | plang: <After 65. Kxf5, black can play literally any move that doesn't immediately give up the rook and still have a draw.> 65 Kxf5 loses for White |
|
Jan-18-11
 | | Marmot PFL: Rf8 would still lose |
|

 | | WannaBe: Just looked this position up on endgame database, best moves are all drawn, black must blunder for white to win. |

 | | Gypsy: <WannaBe: Just looked this position up on endgame database, best moves are all drawn, black must blunder for white to win.> Like 66...Rg7+?? |
|

 | | Kinghunt: If in this position (after 66. Rg5) it were white to move, white would win. As it stands, this is an easy draw. |
|

 | | deadwood53: I think at 65 black checking on the g and h files would quickly show a draw, if white K goes to the f, check, take the rook and then take the opposition and it is dead draw time. |

 | | Peligroso Patzer: Per tablebase, after <66. Rg5>, any Rook move along the 7th rank, or to e3, e2 or e1 draws, but 66. ... Re8? would lose, which is not immediately obvious. |

 | | Domdaniel: *Still* at it, eh? They earn their megabucks, these young celeb chessplayer types ... |

 | | Strongest Force: What is Giri's problem? Why don't he give the draw... |
|
Jan-18-11
| | chancho: Draw agreed finally. |
|
| Jan-18-11 | | marcwordsmith: done. draw agreed |
|
| Jan-18-11 | | theagenbiteofinwit: Good for Nakamura, it seems he's been studying endgame theory in lieu of playing bullet chess. |

| | Domdaniel: <Strongest Force> -- <What is Giri's problem?>
I guess playing out a Rook ending vs Nakamura is like an hour's worth of super-GM tuition ... useful for the future. |

 | | YouRang: Giri will want to know that this ending position was winnable after all! I proved it against Little Chess Partner. Here is the winning technique I used:
<70.Kg4 Ke7 71.Rg7+! Kd6 72.Kg5 Rf8 73.Kg6 Ke5 74.Re7+! Kf4 75.f6 Rg8+ 76.Kh7 Rg5 77.Rg7 Rc5 78.f7! Rc8 79.Rg8 Rc7 80.Kg7 Kf5 81.Re8! Kf4 82.Kg8 Rxf7 83.Kxf7  > So the basic idea is to coerce the opposing king to run around *behind* the advancing pawn so that his rook is left alone to stop the pawn. That's when you've got him! ;-) |

 | | patzer2: <YouRang> I assume that was tounge and cheek analysis? I've won a few endgames with a little help from my opponents, and that's what would be needed here. |
|
Jan-18-11
| | patzer2: I trust Nakamura will look for some improvements in this line, as he had to fight much too hard to hold the draw here. Perhaps 14...a6 offers some improvement for Black. Earlier, my own preference would be for 5...d5 over 5...Bb4+. |
|
Jan-18-11
| | YouRang: <patzer2: <YouRang> I assume that was tounge and cheek analysis? > Very much so (although it was a real game played against LCP from the final position forward). :-) |

 | | Eyal: This variation looks rather lousy for Black. In the recent Aronian vs Karjakin, 2010 Karjakin (who played 12...b6 instead of d6) also got under heavy pressure and managed to draw only by the skin of his teeth. Btw, in addition to some classic 4 vs 3 rook endgames mentioned during the live kibitzing, the following more recent one is also quite instructive: N Dzagnidze vs N Zhukova, 2008. |
|
| Jan-19-11 | | Kazzak: That had the early e-4 which I was hoping for yesterday, Eyal. I've been trying to see how it would have changed things between Giri and Nakamura. I see 48. e4 mentioned as an option by Chessdom. |

 | | crazybird: <GM Hikaru Nakamura: After a relatively bizarre set of transpositions we ended up in a Nimzo/Queens Indian hybrid. Eventually we transposed into the Aronian-Karjakin game from Moscow this past November. However, I came up with an improvement in 12…d6 and 13…Qa5. Oddly enough, I had looked at this variation recently, but I then had a complete brain freeze and miscalculated 14...Be6 and chose 14…Rd8 instead. After this one disastrous move, I suffered for the rest of the game. I suspect Anish missed something in the middlegame as I think it should have been winning at some point. We reached a classic rook and pawn ending where I had to suffer for 20 moves before salvaging a draw.> |

| | Zkid: <YouRang> Sorry, but this position is a dead draw to anyone who's studied the theory. Rg7+ Kd6?? is a big mistake, instead Kf8 leads to the Philidor position after (say) Ra7 Rb6 Kg5 Rc6 f6 (only way to try to make progress) Rc1! Kg6 Rg1+ Kf5 Rf1+ and the checks salvage a draw. By the way, see http://www.k4it.de/index.php?topic=... for a database which plays perfectly for all positions with six pieces or less. |

 | | tpstar: <dead draw> Little Chess Partner is an intentionally weak computer engine installed on this site as a study aid - decent but beatable. Last I knew it had no opening book and no endgame tablebase, so references to its analysis or its results are meant in jest. |
