how can black win this move ? |
|
| Jul-21-10 | | WhiteRook48: where is the win after 36 Bb4? |
|
| Jul-21-10 | | AuN1: 36...Qxd7 and white has no compensation for the exchange |

| Jul-21-10 | | peabody88: <WhiteRook48: where is the win after 36 Bb4?> 36...Bxb4 and Black is one Bishop up with no compensation for White. |

| Jul-21-10 | | leachy: I'm almost certain that 32. Nxg5+ wins.
Was going to post analysis now but that will follow (I have almost written it all up but have other things to do now). I was surprised 'Shak' didn't play this at the time as this sort of thing had been in the air for some time and Naiditsch was down to a couple of minutes on the clock. Even without analysing it feels at least good enough for a draw if Arkadij can find a defence in his limited time. Perhaps Mamedyarov hallucinated something (as per the blunder he made a few short moves later). The move played (Nh2) looks like an admission that your attack has gone wrong or something. |

| Jul-21-10 | | ounos: 32. Nxg5+ hxg5 33. Bxg5 Rg8 34. Rxd7 (or what?) Bxg5 35. Rxf7+ Kh8 should be at least holding for black.
click for larger viewIn this position, if white's queen were magically able to move to b1, then white would be probably winning (check it out!): 36. Qb1 (teleportation) Rg7 37. Qb8+ (that's why Qb1 is needed, because the black queen controls d3 and c8), and either 37. ...Rg8 38. Qc7, or 37. ...Kh7 38. Rf8 |

| Jul-21-10 | | Atking: Ounos 32.Bxg5 makes to me more sense. |
|
| Jul-21-10 | | ounos: Hmm, good call Atking. I don't see anything better than 32. ...Qb6 in that case, ending up a pawn up for white, and winning chances. |
|
| Jul-21-10 | | acirce: <Mamedyarov again decided to make a knight move (32.Nh2) but 32.Bxg5! looks absolutely killing since after multiple captures on g5, the black rook will be left hanging on d8, and after 32…Qb6 White has the extremely difficult-to-find 33.Bf6! Rg8 34.Ng5+!! followed by Qd3+ and Rxd7 with a winning game.> http://www.chessvibes.com/reports/d... But it should be mentioned that the win doesn't depend on that line. The simplest is just 33.Bxe7 Qxc7 34.Bxd8 with an extra pawn and a good position. 32.Nh2 is not bad from a practical viewpoint, especially with Black in time trouble as was the case. After Black's 32..Qe2 he has the pretty simple 33.Qf3 Qxf3 34.Nxf3 and he picks up the a-pawn for free or should win after 34..Bb4 35.Bxb4 axb4 36.a5. But Mamedyarov kept moving quickly despite having much time left compared to Naiditsch. |

 | | tamar: Black can improve after 32 Bxg5 hxg5 33 Nxg5+ Bxg5 34 Qxg5 Qe2 (or 34...Qd3) when he has a perp (Qd1+ Qxh5+) if White takes the rook. 
click for larger viewI suspect Mamed saw this little trick, which can be very irritating, changing the assessment of the whole line, and it upset his equilibrium. |
|
| Jul-21-10 | | samikd: Did White have to resign immediately ? Black is an exchange up but all the pawns are on the same side and I dont think the endgame is an automatic loss for white. Or am I missing something ? |
|
| Jul-21-10 | | parisattack: A chessic tragedy! I haven't felt this bad over a loss since Botvinnik-Petrosian 1965 when the former blundered a brilliantly executed - and totally won game. Mamedyarov is soooo very close to the Top-3 now! I hope he can quickly put this one behind him. |

| Jul-22-10 | | ajile: What's wrong with 24.f4
Seems obvious. |
|
| Jul-22-10 | | Gilmoy: <ajile: 24.f4> f5 25.exf6 Nxf6 26.Qh3 Ne4 and Black is getting way too much counterplay. Or 25.Q<any> g4, and White has no more pawns to throw at Black's wedge. Hence Shak keeps his f-pawn in reserve for exactly that purpose -- <24.Qg3> restores the 25.f4 threat. Black saw all that too, and <24..Qb2> annoyingly forks Bd2 and d4. On 25.Be3? <too passive, it demotes itself into a big pawn> f5 26.exf6 Bd6! <usefully covering c7>, and Black has the same Nxf6-Ne4 tour, with an immortal-worthy shooting gallery. Looking deeper, Shak realizes he won't ever get f4 anyways, and he prefers to keep his Bd2 offensive, so that <26.Bc3> can boot the Q out, which leads him to <25.Nf3> as the only way to fork-save both of his weak points. |

| | tamar: 24 Qg3 impresses me more after studying it with the help of Rybka 3. It inhibits the 24...f5 breakout move which Black needs to give his pieces full activity, and which was in the air as <Gilmoy> points out in the previous post. If now 24...f5 25 exf6 Nxf6 26 Rc7 Qb2 27 Bc3 Qc2 28 Be1 Qh7 29 Qb3 and Black is barely hanging on after the forced sequence rescuing his queen, and is still in danger of going down material. |
|
| Jul-22-10 | | mike1: White should play 25th Qd3 instead of Nf3. The black queen needs to move back or facing Rcb1. White can follow this up with f4, Nf3 and so on. |

| Jul-22-10 | | ounos: <Black can improve after 32 Bxg5 hxg5 33 Nxg5+ Bxg5 34 Qxg5 Qe2 (or 34...Qd3) when he has a perp (Qd1+ Qxh5+) if White takes the rook.>
No trivial perpetual, but perpetual it seems.

Thanks excellent analysis. |
|
| Jul-22-10 | | 4tmac: Good game. Good analysis. More to it than meets the eye. No wonder Mamedyarov was mad he screwed it up. |
|
| Jul-22-10 | | whatthefat: Ha, wow. How much time did White have on the clock here? |
|
| Jul-22-10 | | acirce: A bit more than 15 minutes according to the offical relay. Black was down to, I think, 1:13 (or something very close to that). |
|
| Jul-26-11 | | Nietzowitsch: <samikd: <Did White have to resign immediately ?>> At least he did so.
Here is a video, showing the final minutes of the game:

|
| Jun-08-19 | | Howard: Mamedyarov annotated this game for NIC, and he showed at least two forced wins that he overlooked. He was so rattled by this that he blundered with 36.Rxd7
when he actually had intended 36.Rb7.
He immediately resigned, as he had now just dropped the exchange. |
