| Jan-23-12 | | Shams: <it's a major theme in the najdorf, too, shams.> Yes, and other Sicilians too. But as <keypusher> pointed out Black is not handed the bishops in those lines. <keypusher> You surprise me, the kingside fianchetto alone would seem to put this in a whole different phylum from the Najdorf game. Which doesn't say I'm right about ...e5, of course. |
|
| Jan-23-12 | | Shams: <several sicilian main lines can't be understood in terms of general principles; they work out for black even though they "shouldn't".> This is only true if you don't count dynamics as a "general principle", but of course you very much should count it. "Keeping afloat via the tactics" is a general principle. |

I'm just being obnoxious and contrarian, of course. I think ...e5 would be a bad move here (on move 9; not sure it was bad when Gashimov actually played it) and obviously it's a perfectly good move in the Najdorf. But I also think that the example of the Najdorf shows that to say that move X weakens Y square, or even that it leaves Z pawn backward on an open file, is not an adequate basis, without more, to say that move X is bad. |

| | keypusher: <hm. i wonder if watson says anything about this in secrets of modern chess strategy ...> He does, as I recall. But I thought Michael Stean did a good job in Simple Chess. |
|
| Jan-24-12 | | frogbert: i guess "dynamics" features more prominently in 'modern chess strategy' than in the older, more dogmatic understanding of "sound play". and hence that my statement possibly should be modified and/or restricted to be referring to the principles of what's "positionally & structurally sound". btw, i agree with you on it being quite a leap from this game to the sicilian positions where black plays d6 and e5. |
|
| Jan-24-12 | | Shams: <...not an adequate basis, without more, to say that move X is bad.> I agree. Maybe I should have given a more complete response. I do know you hate it when general tenets are offered, unadorned, as analysis. Here the general principle just struck me as totally vindicated. Still: Committing twitter-length evals to publication here should be a privilege reserved for Masters. I'll show more work. |

| Jan-24-12 | | frogbert: my previous post was directed at shams, obviously. :o) < I also think that the example of the Najdorf shows that to say that move X weakens Y square, or even that it leaves Z pawn backward on an open file, is not an adequate basis, without more, to say that move X is bad.> it's tempting to agree with this too, keypusher - but the implicit context of most such statements is the specific position, and since most chess commentary doesn't go into enormous amounts of detail, we're mostly supposed to trust the annotator on his judgement/description being true for the concrete position at hand. so, we need to trust annotator shams on this, unless he explicitly shows us that he has dug deeper. :o) |

| Jan-24-12 | | Shams: <SimonWebbsTiger> Can't leave the thread without noting that fine contribution of yours. <Simple Chess> Superb book. |
|
| Jan-24-12 | | SimonWebbsTiger: or Pachman.
One of the major points is ...e7-e5 in the Sicilian restricts white's attacking chances by grabbing control of d4 and f4 and preventing any e4-e5 thrusts from white. Having settled the centre, black is placed to mount his minority attack with b7-b5 and pressure down the c-file. |
|
| Jan-24-12 | | SimonWebbsTiger: apropos Watson and the backward pawn in the Sicilian; he discusses the following concepts: The piece arrangement with a W N on c3 and N on d5 -- the N on c3 is Dvoretsky's superfluous piece; it's not doing anything. The N on d5 looks pretty but if it isn't helping white's play, it is merely standing in the way of pressure against the d6 pawn. Black can play around the strong point and N on d5. As Watson also notes, it took a long time with lots of analysis and GM praxis before such conceptual changes took place. |

 | | maxi: One of the first chess books that landed on my hands was a recount of the XXVII USSR Championship. I remember my surprise at seeing Petrosian (I think it was him, not sure) playing e7-e5 in the Sicilian. I went "What! Why is that fool weakening the Pawn structure?" Admittedly, I still had a lot to learn. |
|
| Jan-03-13 | | haydn20: Didn't some chess writer once write "A weakness is only a weakness if it can be exploited."? For instance, the hanging pawns, or White's isolated d-Pawn in some openings. It's possible (maybe not here) that while a player is piling on a d Pawn, he is getting slaughtered on the Kside. |
|
| Jan-03-13 | | haydn20: So I checked 9...e5 in Opening Ex & it's not there, so I tried one line 10. Qd2 Nbd7 11. Rfd1 h6 12. Bxf6 Nxf6 13. Nb5. The hole at d5 may be bad, but the potential one at f5 (after a forced g6) may be worse, and the White B may xray Black's position from h3. And yes the d6 P looks like a money-pit. |

 | | Everett: ajile: Black has a pretty dismal position with less space and almost zero counterplay. And what separates GMs from regular masters many times is simply patience. The ability to tack back and forth and wait for a slight misstep by the opponent. Plus with the space advantage White will usually have more ways to improve his position and mobility.> Karpov-style. Carlsen has translated Karpov's style into 21st Century chess language. |

| | maxi: Yes <haydn20>, Black's position has been compromised. But isn't that the difference between good players and great players? Knowing when established rules do not apply? |
|
| Mar-21-13 | | cormier: 8...Nb8 should move, it would be more precise .... eighter to c6 or a6 |

 | | chancho: Sad to see that in less than two years after this game was played, that Gashimov would pass away. :( |

 | | perfidious: <maxi....isn't that the difference between good players and great players? Knowing when established rules do not apply?> Part of improvement in chess-at a humbler level as well-is achieving this sort of understanding. By memorising certain precepts, one can come to be an average player, but greater gains come with the experience and knowledge that come as one learns the numerous exceptions to the rules. |

| | Everett: <16..Rxc4 17.Nxe6 Rxe4 18.Nxd8> favors White, as does <16..Rxc4 17.Nxe6 Qc8 18.Rd4> Pretty slick. |
|
| Jan-11-14 | | Dave1: Rd2 and after Rxc4 Nxe6 Rxe4 Nxd8 there is no Rxe2 and R is bad placed as white can play Nb7 with the threat Nxd6 |

 | | Domdaniel: <Part of improvement in chess-at a humbler level as well-is achieving this sort of understanding.> As <perfidious> implies, this is not a matter of either/or. It's not a question of crossing a single threshold, but several. In order to improve, it is necessary to absorb and discard the truisms of successive levels of chess ability. |
|
| Jan-09-16 | | ajile: White plays positionally to pressure Black's weak d pawn. Black tries to escape the pressure by giving up this pawn in exchange for White's h pawn but this only trades one White advantage for another since now White gets an unopposed q-side pawn. Nice play by Carlsen. |
|

| | Domdaniel: <well, i guess we're back to my friend's explanation: several sicilian main lines can't be understood in terms of general principles; they work out for black even though they "shouldn't".> Which only implies that there's a problem with 'general principles'. |
