 | | AylerKupp: Make sure that you all check out Yifan Hou vs A Ushenina, 2013 from the current Woman's World Championship, a Sveshnikov Sicilian. You will probably have a sense of déjà vú, particularly when you see the final position that I am sure came up in as many Team Black analyses as it did in Team White analyses. As my Team White teammates may remember, I was a big proponent of not playing Nce3 in order to avoid the ...Bxe3 capture, and I was gratified that Yifan Hou felt similarly, although she was unable to win either. So maybe my enthusiasm was somewhat misguided and should be curbed. I was also a proponent of h2-h4 after ...Bg5 to (likely) force the Black bishop to h6 prior to exchanging knights in order to make it more difficult for the bishop to move to the q-side. So I had several engines analyze the position after 13...0-0 14.h4 in the Yifan Hou vs A Ushenina, 2013; I posted the results in that game but, to make a long story short, it looks like my enthusiasm for an early h2-h4 was also misguided and should be curbed. Oh well. Excuse the amount of duplication between this post and the one in the Yifan Hou vs A Ushenina, 2013 game since I wanted the latter one to be able to stand alone. |

| Sep-12-13 | | morfishine: <Stunningmove> Nice game and very interesting analysis! (I'm only up to page 70). I look forward to the WT game and also being on the same side again! On a side note, I hope <kwid> and the other Team members weren't too upset that we declined the initial draw offer. Thats just the way the chips fall in voting chess, so no offense intended ***** |

| | AylerKupp: <<DanLanglois> The world most certainly does revolve around me.> Well, then I stand corrected. But you better let Copernicus know. He will be so disappointed that he was wrong so many years ago. |

| Sep-13-13 | | YouRang: Nice pun (given all the exchanges at d5), and if I'm not mistaken, credit goes to <PinnedPiece>. |

 | | offramp: A really good game! White plays like a young Karpov and aims exclusively for control of d5. But he does not occupy the square, so black plays the very Nimzowitschian 24....d5! and all his problems disappeared in a single 4-day move. |
|
| Sep-13-13 | | PinnedPiece: <YR: credit goes to <PinnedPiece>.> Much more should go to <mistermac>. He was far more involved in the thinking in the game, and several days ago suggested alternate titles involving the d5 square....btw I voted 24.Nd5 but offered the team no convincing rationale. I really had none... . |

| Sep-13-13 | | Abdel Irada: <btw I voted 24.Nd5 but offered the team no convincing rationale. I really had none...> It was a Sicilian. One never needs a reason to play Nd5 against the Sicilian — *especially* if it's a sacrifice. ;-) ∞ |

But he does not occupy the square, so black plays the very Nimzowitschian 24....d5! and all his problems disappeared in a single 4-day move.> There is no feeling in chess so liberating as to play, unexpectedly and with impunity, precisely the move that one's opponent has spent his whole force in an effort to forestall. Not only does it positionally free one's game, but the psychological effect upon the opponent is devastating. Consider: He has invested much thought and effort to contain a single strategic idea, and when he is most secure in the certainty of its impossibility, it bursts upon him like a gout of water from a stone. ∞ |

| | mistermac: None of you blokes have ever heard of Slaghter on 5th Avenue, have you? BTW, I remember thinking before the long eschange as it slowly built up of what it must have been like at the Somme when both sides in that terrible conflict brought up their big guns and ammunition, and concentrated their troops. It must have been fearful and ominous! |

There is a really good example of the same thing (but at a higher level) at Karpov vs Korchnoi, 1978, where Kortschnoi said he wished he hadn't moved his a+b pawns before playing ....d4. |

Chessgames Challenge: The World vs A Nickel, 2006 |
|
| Sep-13-13 | | YouRang: <Nickster> I'm starting think you're right -- white missed a win! <31.<Kd1!> f5 32.Kc2 fxe4 33.Rd5 Rf8 34.<c4!> Rf2+ 35.Kc3 Kf7 36.Rxa5 Ke6 37.Ra6+ Kf5 38.<c5!>> The deep engine analysis I've done so far is pointing to a white win. Of course, there's room for doubt that white could have found all these and subsequent key moves without computer assistance. Anyway, on behalf of team Black, I would like the thank team White (and our lucky stars) for <31.Rb2?!> ;-) |

| | playground player: <benjinathan> I stand corrected. I just don't like Sicilian games, I guess. |
|
| Sep-13-13 | | benjinathan: <hms123: I voted <Kd1> with the idea of getting the King to <c2> and the rook to <d5>. This gives us an active rook and a King that is helping on the q-side.> <hms123> wins the endgame prize!! Sadly, he finishes last in the persuasion sweepstakes.... |

On a side note Stockfish 4 is impressive. |
