 | | Gilmoy: <14..b4!?> offers a pawn for lengthy pressure against the pinned Bc4. White looks deeper, accepts the pawn, then patiently untangles herself. After <22.Bb3> White is safe on the Q-side, and gets tempi for her 4-v-0 K-side attack. The key shot <20.d6!> returns the 2nd pawn to deflect the DSB onto a vulnerable square -- White threatens Nc4 with a hidden double. Black sees that she will soon need f8 and e7 as flight squares, so it can't retreat there. <22..Be5 23..Bc7> looks like a miscalculation: Sebag cedes a tempo and blocks her own Qxc2 threat just to stay on the h2-diagonal. What makes that so much better than c5 or b4? Possibly Nxe3 and Bf4? Of course 36.Qc6+ and 37.Q(xd7,g6)#. |

|
| Aug-04-10 | | Blunderdome: This is a great game. |

| Aug-04-10 | | ycbaywtb: talk about grabbing the initiative |
|
| Aug-05-10 | | Ladolcevita: Surely grandmaster level... |

 | | whiteshark: For some unclear reasons the rd 5 bulletin didn't report about the players comments on their game at the press conference. Maybe they haven't been there? |

 | | Phony Benoni: A logical pun. |
|
| Aug-11-10 | | Eduardo Leon: I don't get the pun. Really. |

 | | Elsinore: If and only if: a biconditional. |

| | Elsinore: Oh, someone beat me to it. |
|
| Aug-11-10 | | Ladolcevita: If and only if...
I like this pun... |

 | | Once: Here is Wikipedia waxing lyrical about "if and only if" "In logic and related fields such as mathematics and philosophy, if and only if (shortened iff) is a biconditional logical connective between statements. In that it is biconditional, the connective can be likened to the standard material conditional ("if") combined with its reverse ("only if"); hence the name. The result is that the truth of either one of the connected statements requires the truth of the other, i.e., either both statements are true, or both are false. It is controversial whether the connective thus defined is properly rendered by the English "if and only if", with its pre-existing meaning. Of course, there is nothing to stop us stipulating that we may read this connective as "only if and if", although this may lead to confusion." |

Took me a few minutes to see this. |

| | Check It Out: <"...although this may lead to confusion."> that's some irony there. <Once> I understood the statement before I read that wiki entry, now I have no idea what they are talking about. |

| | Once: <Check It Out> Yes, me too. Having said that, it must be true because I bet this paragraph (or at least parts of it) has found its way into hundreds of student essays. |
|
| Aug-11-10 | | TheRavenPK: I wouldn't be surprised if this was Tal's game.. And I mean that as a compliment for Yifan :) |
|
| Aug-11-10 | | Eduardo Leon: Oh, "if and only if," that was the hidden phrase. To think I read that phrase all the time in mathematical proofs... |
|
| Aug-11-10 | | Ladolcevita: Yes,frequently.... |

 | | Dr. Funkenstein: Did Sebag refuse the queen trade because of
20. ...exd3 21. exc7 dxc2+ 22. Kxc2 Rb7 (Rxc7? 23. Bf4) 23. Bf4 or am I missing an even better continuation for white |
|
| Aug-11-10 | | Octal: Dr. Funkenstein: You don't appear to be missing anything as the threat of 24 Bxa6 is pretty difficult to meet. 23 ... Nc5 24 Nb3 Nfe4 25 Rd4 and 26 Rgd1 will just pile up the pressure. Black doesn't seem to have any useful moves (25 ... Nxb3 26 axb3 Bc5 27 Rd8+) |
|
Aug-11-10
| | Gilmoy: <Dr. Funkenstein: 22..Rb7 23.Bf4> Now White threatens 24.Bxa6, so the Rb7 line seems to still commit Black to 23..Rxc7 24.Bxc7 Rxc7 25.b3. The alternative 22.Ra8 is just toothless. Also, g5 looms, so Nd7 will-be-hanging.
Black already gave up on the K-side several moves ago. Critically, giving up her b-pawn eliminates her Q-side storm threat, whereas White's K-side pawn storm is still very much alive. So she must keep her Q in play. |
