| Jul-02-09 | | Knight13: <chessgames.com> Apology message deleted because it was "off topic" so to speak. And for those who think that ...hxg4 is a mistake:
Black's gonna lose his h5 pawn after gxh5.
So ...hxg4 was actually a logical move, though it wasn't good enough. |

| Jul-02-09 | | znprdx: OH well - Once again Knight vs Bishop superiority(sometimes so obvious)....something Carlsen has pulled off before ...This victory has to sweet since supposedly Jakovenko is considered a formidable endgame specialist |

 | | acirce: <I dunno, it looks like Jako mangled that pretty badly. He had some fairly clear drawing attempts before time control from what we looked at with LarryC. Passing up the chance to play ..c5 cost him. He may have missed that trick with the knight being trapped on h7 after 37..c5 38.bxc5 Kxc5 39.h5 gxh5 40.gxh5 f6 41.h6 Bg8 42.Ne6+ Kd6! 43.Nf8 Ke7 44.h7 Bxh7 45.Nxh7 Kf7 draw. White can try other things, but without ..c5 Black's just waiting for White to break through on the queenside.> http://www.chessninja.com/dailydirt... |

| Jul-02-09 | | Gambitor: The final position doesn't require computer analisis,, black has the king very far away from the action, the c pawn will fall, and his bad bishop has nothing to do against the white's knight. |

| Jul-02-09 | | percyblakeney: <I dunno, it looks like Jako mangled that pretty badly. He had some fairly clear drawing attempts before time control> The 37. ... c5 line looks like it would have drawn, but it was maybe not that easy to find. GM Zagrebelny missed it at Chesspro and Chessvibes and Chessdom didn't mention the possibility in their annotations either. |

| | acirce: <percyblakeney> I agree. On the other hand it seems Mig is probably right that without trying ..c5 it is close to hopeless. But I don't know, of course. More strange to me is that he ended up in such a difficult position to begin with. To be noted is that just because you are a great endgame player it doesn't follow that you play all endgames well, but as most often it probably had more to do with his opponent. |
|
| Jul-02-09 | | percyblakeney: Chessvibes point out that the position after 23 moves was almost identical with the one in A Volokitin vs E Alekseev, 2009, the only difference being that Carlsen's rooks were on d1 and e2 instead of e1 and d2. |
|
| Jul-02-09 | | returnoftheking: It seems Carlsen has a good memory.
But I prefer this game
A Volokitin vs E Alekseev, 2008 |

 | | karnak64: I had to leave mid-game and just replayed it. The boy wonder seems to have made something out of nothing. Pretty impressive. |
|
| Jul-02-09 | | returnoftheking: In power chess with pieces Timman has an entire chapter about these seemingly easy/drawish positions. The side with the bishop is sometimes surprisingly powerless. Here are a number of examples-different from the game of today but also with some similarities, mainly the difference between the power of knight and bishop-even when there are no obvious pawn weaknesses. Saidy vs Fischer, 1964
Karpov vs Kasparov, 1984
or more recently
Karpov vs Kasparov, 1984
Today's game was certainly impressive but with all these games you get the impression that the defending side has to make little mistakes sooner or later..
But I still don't know what those where today. |

| Jul-02-09 | | SugarDom: Wow, after the queen exchange and it was late night here, i slept thinking it would be a long endgame ending in a draw... |

 | | visayanbraindoctor: 
click for larger viewIn this position after 36. g4, Black is in deep trouble because of his weak pawns and bad Bishop. White on the other hand does not have to worry about defending his pawns, is about to create an outside passed h-pawn by which to divert Black's King to the Kingside so he can attack the Black Queenside pawns with his King, and can harass Black's weak pawns with his King and Knight. What is the only practical way for Black to survive? Black will have to liquidate as many of his weak Queenside pawns as he can, or they are sitting ducks. Thus, a plan based on an eventual c5 is perfectly logical in this position, as it liquidates the weak Black c-pawn. I am sure that Jakovenko would have done this if he were not in time trouble (36... hxg4 37. fxg4 c5). However, managing one's clock is part of the game, and Jako did not do well in this particular aspect in this game; and so is saddling your opponent with weak pawns and trying to create outside passed pawns, which Carlsen proficiently did. And so Carlsen got the full point. |

| Jul-03-09 | | percyblakeney: Also Lilov missed the drawing resource 37. ... c5 in the full Chessbase report: http://www.chessbase.com/newsdetail... |
|
| Jul-03-09 | | percyblakeney: <It seems Carlsen has a good memory> Jakovenko was almost half an hour up out of the opening after following a game that was drawn five-six moves later, so I don't think his memory is too bad either... |
|
| Jul-03-09 | | returnoftheking: hehe..I know, I am sure both knew that game.
@ vishy..interesting; didn't know that game. |

 | | Ulhumbrus: The move 34...Ra6 shatters Black's Queen side pawn structure after the exchange 35 Rxa6 bxa6. On the other hand, Black's Rook seems to lacks any way to get into play. This suggests the question of how Black can bring his Rook into play without breaking his Queen side up.
If we look at an earlier position, on the poaition after 27 Rxa4 White's Rook threatens to occupy the seventh rank while Black's Rook is unable to get into play. So how can Black disentangle himself? 27...Bc8! defuses a potential Ra7. On 27..Bc8 28 Rd4 Ke8! prepares to bring Black's Rook into play via the d file. On 29 Nd3 Rd5 the aim is achieved. From contortion to the stars. According to Nimzovich, in a bishop versus knight ending, the bishop prevails because the bishop is wonderfully good at stopping an opposing passed pawn or else at supporting his own. So why isn't the bishop wonderfully good here? One answer is that Nimzovich's explanation may be intended to apply in positions where other things are equal. In the position after 42 Ke3 other things are not equal at all. They are in fact most unequal. In the position after 42 Ke3 if Black tries 42...Bb1, on 43 Kf4 Kd5 44 Ne5 Kd4 45 Nxf7 Kc3 46 Ne5 Bh7 47 Kg5 Kb3 48 Kh6 Bg8 49 Kg7 Bd6 50 h6 Be4 51 Ng6 wins. In this variation after 43 Kf4, White's King, Knight, and passed h pawn are all ahead in development of their Black counterparts, namely, Black's King, Bishop, and f pawn. Moreover Black's Queen side is much more vulnerable to attack than White's Queen side is vulnerable to attack. |

 | | Calli: <The move 34...Ra6 shatters Black's Queen side pawn structure> why not 35.Rxa6 Bxa6 36.b5 c5? |
|
| Jul-03-09 | | znprdx: I'm curious: A classic Coffeehouse tactic:...33.Ba6 (perhaps that was the reason for Bc4 in the first place)certainly looks preferable to the text... Also I don't understand how g4 forces the creation of a passed pawn - doesn't ...f6 hold at some point? |
|
| Jul-03-09 | | returnoftheking: calli..my c** computer with fritz 5 gives white an advantage (+1) after c5 bxa6 cxd4 Kd3 bxa6 Kxd4, for what that's worth. |
|
Jul-03-09
| | Calli: <returnoftheking> It makes a nice study in opposition. Black can try to block with f6 and Ke6-Kc6-Ke6. Can White breakthrough on the k-side? I don't know the result. |
|
| Jul-03-09 | | returnoftheking: I guess white always has a tempo in store with it's pawn on g2. Funny (not engine made so maybe not so funny..) line after Kxd4 would be
..f6 f4 Kc6 ke4 Kd6 f5 g5 g4!
but black can of course play other than Kc6 and Kd6 or maybe even go for the a pawn. I can imagine it was hard for time troubled Jakovenko to decide on this ending. |

 | | tamar: These endgames have really let us see a gap between Magnus and the other top GM's. The openings are so long now, and chiseled almost to perfection with computers peering almost into every possibility, that once the players get fully on their own, you often notice a drastic falling off in strength. With Magnus there are fewer seams. Just very strong moves, and very few errors. |
