| | OhioChessFan: Thanks CG.C This site rocks. That is all. |
|
| May-14-13 | | Marmot PFL: Karjakin and Carlsen are even for practical purposes since Karjakin has already played Hammer and MC hasn't. |
|
| May-14-13 | | chessdgc2: chessgames.com Thanks for the Carlsen/Radja show! |
|
| May-14-13 | | beenthere240: I imagine Karjakin is getting nervous. Drawing the rest of his games might not work out so well. The laugher is that Naka was quoted as saying that Carlsen's defeat of Karjakin gave him (Naka) a renewed chance to win the tournament! |

| May-14-13 | | Ulhumbrus: 43 Re1 threatens Re7. Instead of 43...Bb8 which allows the move 44 Re7, 43...Re6 prevents it. |
|
| May-14-13 | | Kinghunt: Unbelievable endgame play by Carlsen. This is arguably his "least-winning" win (aka, he started the endgame with virtually no advantage but won it anyway). Anand is going to be shaking in his boots when he sees this game tonight. |
|
| May-14-13 | | csmath: Brilliant game. Just now I passed it through engine and indeed Magnus made no mistake while baiting Radjabov in number of traps.
22. e4 is not an error as it clearly leads to ending where only white can play for a win which is what Magnus wanted, apparently. During the game I did not see 57. ... Be5 as an error but I now I see it but to be fair to Radjabov, only with a help of engine.
62. ... Rh1 is clearly an error but it is already hard to play black. This is indeed masterful game. |
|
| May-14-13 | | Eyal: A pity this game wasn't broadcast live from the start; it would have been fun to go over all the comments saying that it's a dead draw and that Carlsen has no chance to win. |

| May-14-13 | | DeepTrouble: Molloychess in responde to haydn20:
<Missed a win? If you are talking about Rb1+; 51, Ka2, then I don't think that is a win necessarily. It's a rook ending that the computer evaluates as better but Carlsen may have evaluated as drawish.> I agree: Ka2 didn't lead to a win, although some engines evaluated it to as much as +0.9: The pawn gets stuck on a7, and white can't make any progress because of black's centralized king. So Haydn20's assumption that Carlsen "blew a win" is incorrect. Instead, Magnus played Ke2, which was a practical move. On the press conference he said that he played this move instead of Ka2, because Ka2 didn't lead anywhere ("Ke2, if I was to play for a win"). You should check out the press conference: It turns out that he had everything under control. Very impressive analysis. |

 | | tamar: Does anyone have a line after 62...Bg1 that does not lead to a draw? If 63 Ne3 which was Magnus intention, the immediate 63...Bxe3 leads to a tablebase win for white ending with White saving his a pawn and winning 
click for larger viewBut I haven't been able to find a win with the sequence 62...Bg1 63 Ne3 Ra2+ 64 Kf3 Kd4 65 Nxc4 Kd5 66 Ne5 Bd4 67 Rh6 Bxe5 68 Rh5 Ra3+ 69 Kg4 Ke6 70 Rxe5+ Kf6 71 Rh5 Kg7 72 Kxh4 Rxa6

| May-14-13 | | Marmot PFL: <tamar> 70 fxe5 might be better, but I think black still probably draws- with best play. |
|

| | tamar: <Marmot PFL> Thanks for the feedback. The win would have to involve saving the a pawn I think. But I can't find any winning plan for White after 70 fxe5 Ra4+ (only move) 71 Kg5 Kxe5 72 Rh6 Kd5 and Black just toggles back and forth between e5 and d5 with his King |

|
| May-14-13 | | Kinghunt: <tamar> I don't have a line leading to this, but an alternative idea to win would be to give up the a pawn, but cut off the black king. For example, while the position you gave is a draw, this one is a white win, with either side to move:
click for larger viewI'm not sure if it's possible to get this position, but you don't need to save the a pawn, as long as you have the time to control the e file. |

| May-14-13 | | tud: Carlsen is in the same category with Lasker and Korchnoy. Real fighters. Die hard people. Endgame masters. |
|
| May-14-13 | | Eyal: Position after 57.Nd5:
click for larger viewCarlsen thought the decisive mistake was 57...Be5 instead of 57...Ra2+! 58.Kf3 Bd2 and then White doesn't get to check with the knight on e3 and win Black's f-pawn as he does in the game (if he goes after this pawn with 59.Rb6+ Kc4 60.Ne7 Black has 60...Be1). Btw, the press conference can be viewed at http://www.livestream.com/norwayche... (starting at about 12:00 - "Magnus, why is it that you work so late every day?"). Apparently, starting from round 5 they finally have the whole broadcast replayable (in several parts) after it ends. |
|
| May-14-13 | | Eyal: Position after 21...c5:
click for larger viewLooks like Carlsen missed here a tactical opportunity to win a pawn and gain an early advantage: 22.Qb5 Bb6 (22...Qb6 23.Rxc5) 23.Ne5! Qd6 (23...Qxe5 24.Qxb6 and the c-pawn can't be defended) 24.Nc6 Rdc8 25.Ne7+! Qxe7 26.Qxb6 and again Black's c-pawn can't be defended. |
|
| May-14-13 | | ceebo: <tamar: I haven't been able to find a win with the sequence 62...Bg1 63 Ne3 Ra2+ 64 Kf3 Kd4 65 Nxc4 Kd5...> How about 66.Rc8!? here. The a-pawn is a goner but white keeps the knight on the board and can attempt to win the h-pawn later. It's far from a certain win though. |
|
| May-14-13 | | ceebo: With my previous comment in mind maybe 62...Ra5 is better for black. I can't find anything better than 62...Ra5 63.Nd6 Ra2+ 64.Kf3 Kd3 65.Nxc4 Rf2+ 66.Kg4 Ke4 67.Nd6+ Kd5 68.Rc8 Kxd6 69.Rd8+ Ke7 70.Rxd4 Ra2 71.Kxh4 Rxa6 |

| May-14-13 | | csmath: <Looks like Carlsen missed here a tactical opportunity to win a pawn and gain an early advantage: 22.Qb5 Bb6> I doubt he missed anything. 22. ... Bb6 is not given/forced and there are variations here that give black a passer on d-file which is not something Magnus wanted to handle. 22. e4 prevents that and gives him safe ending in which black can do pretty much nothing while white continues to play for a win. I am guessing this was his exact intention. |

| May-14-13 | | Eyal: Position after 37…Kd5:
click for larger viewThe commentator on chesspro, Sergey Zagrebelny, called this position a kind of "zugzwang-light" for Black (http://www.google.com/translate?hl=...). Black goes on to make a series of pawn moves, and after running out of them has to move either king or rook and thereby make some sort of concession – since the white knight isn't attacked twice anymore, either the white king or rook are freed for action (the bishop can't move at all, since Bb8 allows a knight fork on b6). It's not losing yet, but it makes Black's position awkward. That's why Carlsen suggested at the press conference, instead of the natural-looking Ke6-d5 maneuver, an alternative deployment of Black's pieces as a better drawing method: 36...Bb8 37.a3 Bc7 38.Kd3 Kd7 – an important point, I suppose, being that if White tries to drive away the rook, Black's king is just in time to defend it: 39.Kc3 Kc6 40.Kb3 Kb5 (with the bishop on c7 preventing an annoying knight check on d6). |
|
| May-14-13 | | csmath: Although I wonder what would be the game had the black played 21.... d4 which seems as a fixed weakness but not so easy to handle. |

I am guessing this was his exact intention.> Bb6 is not a given, but it's a critical line since otherwise it's clear that Black is losing a pawn (though indeed he has some compensation). I think Carlsen missed it – i.e., the following knight maneuver – because he didn't mention this possibility at all, just said that he didn't see anything except for e4. But it's true that what he played is more consistent with his style in any case. |
