 | | tamar: 25...Bd3 was surprising, but is an only move, for if 25...Bxg4 or 25...Bd7, 26 Re4 traps the Queen. A bravura defense and counter-attack (35...c5!) by Kamsky |
|
| Jul-24-11 | | whithaw: Fantastic play by black. Deep understanding to realize that the a1-h8 diagonal could be neutralized. |
|
| Jul-26-11 | | sevenseaman: Gata identifies the pressure points and neutralizes them. 25...Bd3 and then forcing the exchange of Qs is critical to turning the flow of the game his way. Unfortunately K.O. out of the Candidates, there is consistent evidence Gata would have been a worthier challenger. |

|
| Jul-26-11 | | DrMAL: I suppose 25.g4 might have been praying for an elementary blunder, to me it looked like white merely wanted to eliminate the defending bishop via 25...Bd3 forcefully. After this, white has a slight advantage and tries for more attack. 27...gxh6 looks risky but it was the best move, with 27...Qf7 white's advantage is solid via 28.Ne4 Qd6 29.Qg3 but apparently the benefit via 30.f5 was not seen. For example, 29...Qxh6 30.f5 Ng8 31.Kg2 and black is in serious trouble.
click for larger view Missing the opportunity of 28.Ne4! gave black the ability to survive. Up until move 34 white still maintains an advantage until 34.Qd4+ instead of 34.Qe5+ a tactical mistake (34.Qe5+ Rg7 35.Rf2 and white is still ahead). With 34.Qd4+ Rg7 white cannot play 35.Rf2 because of 35...Rf8! 36.Kf1 Nxf5 losing. With 35.Rf4 black is now slightly ahead via 35...c5 as was played. After 36...Reg8 white's only good move was 37.Kf1 white blundered with 37.Kg2 as the game shows until move 39. 39...Nb4 finishes properly I am surprised white resigned after 39...Ne5 it is very questionable whether black has a win. Either way, this is certainly not one of Kamsky's best games. With the best continuation, 40.Nxd5 Nxg4 41.Rd6 Ne5+ 42.Kf1 black's advantage is only slight, even if black plays best with 42...Rg1+ (instead of 42...Nxd3 the obvious but lesser move). 42...Rg1+ 43.Ke2 Rb1 44.Ne3 Rxb2 45.Kf1 Rb4 46.Rxb4 and either way black takes the advantage is still only slight:
click for larger viewI think this game was probably a draw after black's last move 39...Ne5 (instead of 39...Nb4 that probably wins). I will put it on Houdini and let it compute from move 46 for black overnight. |

| Jul-26-11 | | psmith: <DrMAL> On the end of the game, here is the comment at http://www.chessbase.com/newsdetail... "One presumes Radjabov's clock fell, since resignation would make no sense here." |
|
| Jul-26-11 | | psmith: <DrMAL> The above link also gives your line after 28. Ne4! and further analyzes your line after 34.Qe5+ Rg7 35.Rf2 leading to  , confirming your evals. Their conclusion on the final position is "39...Ne5 After 40.Nxd5 Nxg4 threatening Ne3+ winning the knight. 41.Rd6 Black is certainly better, but the game is far from over. " |
|
| Jul-26-11 | | psmith: It would be interesting to know how much effect time trouble had in the last, say, 5-10 moves. |
|
| Jul-26-11 | | DrMAL: Thanx <psmith> yes, apparently, the ChessBase reviewer (presume, GM) agrees. Not sure when this article came out. "Radjabov missed an opportunity to play 28.Ne4! when after Qg6 29.Qg3 Qxh6 30.f5 Ng8 31.Kg2 Black is in trouble." "34.Qd4+? So close, yet so far! 34.Qe5+! Rg7 35.Rf2 Rf8" "One presumes Radjabov's clock fell, since resignation would make no sense here." "After 40.Nxd5 Nxg4 threatening Ne3+ winning the knight. 41.Rd6 Black is certainly better, but the game is far from over. " The reviewer missed the merit of 27...gxh6 and failed to point out 27...Qf7 was the potentially losing move, yet this reviewer makes some big drama about 25.g4 Bd3 because of the silly blunder 25...Bxg4?? (putting an exclam for each move is unnecessary). Just for grins, from the line I give after the last move, a long term computation evaluation is: Houdini_15a_x64: 30/79 4:55:10 83,006,935,372
+0.33 46. ... cxb4 47.Rb6 Nxd3 48.Nc4 Ra8 49.Rb5
+0.28 46. ... axb4 47.f6 Nc6 48.Rd5 Rf8 49.Rxc5
I thought maybe I was missing something here. Running out of time certainly explains it, including your last post, cheers. |
