The longest game was Mamedyarov-Bacrot, and a very complicated one. Mamedyarov: "In the opening I played the not very popular 7.Qd2 and I think I was better somewhere, but then he just played very well, for example with <16...Bd4!>.

Bacrot said it was difficult for him to perform after yesterday's blunder: "Still I think I played quite well but I missed his 57.Ne6+ and 58.Ng5. Too many blunders." Shipov showed where Black could have saved himself: <66…Rg8!>

He has to play 72…f1N+ in order to survive.
Why not the simple 66 ...f4!? instead.

| May-04-08 | | notyetagm: Position after 70 ... ♔c6-b6
click for larger viewMamedyarov's (White's) next two moves provide a clinic on the tactic <OVERWORKED (DEFLECTION)>. First Mamedyarov played 71 ♘e6-c5!, based on the simple <DEFLECTION> idea that the White c5-knight is taboo because the Black b6-king must <DEFEND> the a7-square from the advance of the White a6-pawn. That is, 71 ... ♔b6x♘c5?? <deflection from a7> 72 a6-a7  . Position after 71 ♘e6-c5!

click for larger viewSo Black did not capture the White c5-knight and instead played 71 ... ♖g8-d8, to keep the White c5-knight out of d7 where it controls the b8-promotion square. Position after 71 ... ♖g8-d8
click for larger viewThen Mamedyarov played 72 ♘c5-d7+!, -again- based on the simple <DEFLECTION> idea that the White d7-knight is taboo because the Black d8-rook must <DEFEND> the b8-promotion square. That is, 72 ... ♖d8x♘d7?? <deflection from b8> 72 b7-b8=♕+. Position after 72 ♘c5-d7+!

| | Jimfromprovidence: <notyetagm> You missed the boat. The point of contention is move 66 for black. You need to direct your comments beginning with that point of the match. |
|
| May-05-08 | | notyetagm: <Jimfromprovidence: <notyetagm> You missed the boat. The point of contention is move 66 for black.> No, I did -not- "miss the boat". My goal is analyze <TACTICS>, breaking them down into understandable parts. I am sure Mamedyarov saw the winning knight maneuvre 70 ♘g5-e6!, 71 ♘e6-c5! way back on move 66 but not us mortals. |
|
May-05-08
| | Jimfromprovidence: <notyetagm> So, you are saying you cannot analyze the position from move 66 for black forward. GM Shirov, whether he is mortal or not, surely did. Please refute his line. I offered my own modest suggestion as well. Refute 66...f4 if you can. |

What interests me is the <TACTICAL> basis for Mamedyarov's 71 ♘e6-c5! and 72 ♘c5-d7+!. |
|
May-05-08
| | Jimfromprovidence: <notyetagm> IMHO, most kibitzers would be more interested in at what point and why black lost the match. At move 70, black had already lost. At move 66 he had a chance. You ignore the gist of the Tournament Bulletin, where Shipov explained how black could have survived, but for some reason you highlight that last sentence of the bulletin only. |

 | | jessicafischerqueen: <Jimfromprovidence> Who cares about your "not very humble opinion"?
<Notyetagm> provides a thorough explanation of a tactical point in the game- a tactic of great beauty. His analysis is in and of itself of great interest and value to me. The fact that he is not interested in analyzing <66...f4> is TOTALLY IRRELEVANT to the value of his explanation of a beautiful tactic. Your comments on his analysis are COMPLETELY POINTLESS. Instead of criticizing someone, provide your OWN ANALYSIS of the point that interests you. |
|
May-06-08
| | Jimfromprovidence: <jessicafischerqueen> I posed the question concerning Shipov's analysis and my own about the losing move, 66 for black because I wanted know what others thought. That's the most salient point, right, to figure out why one side lost and what could have been done about it. <notyetagm>' comments are very nicely done, are instructive, but beg the question of why black lost. That's why I pressed him on the issue. I wanted him to opine on it. |

| May-27-09 | | PinnedPiece: I like this game!
Thought of a pun, too, a bit late for the 2009 contest, ah well. "Persistence of Mamedyarov" |

 | | JointheArmy: Impressive combination from Mamedyarov. |
|
| Aug-06-09 | | arsen387: A very nice game, 38.Ng4 left me in total amazement, in that position I would have surely played smth uninspiring like Nxf5 :) The final N maneouvre is also great. But I like this romantic masterpiece played again by these 2 better Bacrot vs Mamedyarov, 2009 |
|
| Aug-06-09 | | sfm: sfm: Neat counting! 73.d8Q+ wins - on a single tempo! Black eat everything on b8, then the a-pawn and then runs towards the king side. White eats the f-pawn and then play 79.Kxh5, with the black king on the c-file. If Black had made it to the d-file it would be a draw. |
|
| Aug-06-09 | | eaglewing: <Jimfromprovidence: Why not 66. ... f4? and Why not 72 b8Q?> I agree with you with respect to Shipov's analysis, that move 66 by black decides the fate of the game. I'm astonished Bacrot chose Bxd5 at that point, after all, the remaining game line is not difficult to envision for experienced players, because, while not strictly enforced like a mate combination, White needs to push his pawns and then follow-up with Ne6-c5. Otherwise White would be in danger to lose these pawns first and then the game. Your question is, if the the move order in the Shipov-line, 66. ... Rg8 and 68. ... f4 is important, or could be reversed with starting 66. ... f4. I had a look at 66. ... f4 67. Nf7+ Kd4 68. d6, but it does not work. With f4, square e4 is still not accessible for the knight. As far as I can see the Shipov line is still the line of choice, the different move order cannot be taken advantage of by White. Nevertheless, to be sure, ask Fritz about it. Regarding your 72 b8Q instead of a7:
Yes, f1N+ is required, but fine and easy for a draw after Kh1 Rxb8 a7 Rg8 a8Q Rxa8 Bxa8 Ng3+ Kg2 Nf5. Note: Not f1N+ Kh3 Rxb8 a7/d6, due to Rg8/Rg3#. |

| Aug-06-09 | | JohnBoy: <JfP> and <notyet> are after different things. I am with Jim in wishing to understand where exactly Bacrot lost the thread. At the site mentioned above, http://chessok.com/broadcast/?key=p..., Rybka gives a different drawing line for black at 66, and does not even note 66...f4. This is, of course, immediately following white's howler at 66 (missing 66.Nf7+). Maybe one of you engine runners can scour this for possibilities. White's 36th, in anticipation of surrendering up the X, indicates a bold and admirable plan. Bravo Shak. |
|
| Aug-06-09 | | SuperPatzer77: It is one of the instructive games I've learned.
After 73. b8=Q+, White forces simplification that leads to the easy pawn endgame for White. <Notyetagm> Well-done, you've shown us the excellent analysis of three diagrams so, you're right that Bacrot (Black) had no choice. Black was forced into simplification that gives White a easy pawn ending. SuperPatzer77 |
|
| Aug-06-09 | | Big Easy: Can someone please explain the following:
Why doesn't black respond to 37.Rxe7 with 37...Rxe7 instead of the move played, 37...Qxe7? Then when white plays 38.Ng4 there is no discovered attack on the black queen, and the bishop on c3 remains protected. What am I missing? |
|
| Aug-06-09 | | kevin86: After white captures the rook and the pieces are cleared from the queenside,white captures the black pawns and then races the king to g7-it is close. If black can reach f8,he draws,but he comes up short. Sacre Bleu! |
|
| Aug-06-09 | | Big Easy: Never mind on my last post. 38.Qxd6
Duh! |
