 | | Gypsy: But a really troubling variation is <35.Ne7+ Kg7 36.Rc8 Rc8 37.Nc8 a3 38.bxa3 b3!>. Now what? |
|
| May-17-08 | | hitman84: <Gypsy>I think you confused the two lines I posted. I didn't consider 38...bxa3 |
|
| May-17-08 | | holland oats: I'm not sure that 39.b6 is winning. Instead white must threaten mate with rook and knight: 39.Nd6! b2 40.Ne8+ Kf8 41.Nf6, and now black must play Bb6 to avoid mate. This allows white to play 42.Rd1, which not only prevents black from queening but also threatens the knight fork on d7. 42...Bc2 fails to 43.Rh1 Bd4 44. Kf4!, and white can trade his rook for black's pawn and the doubled queenside pawns will win for white. Definitely not an easy line to find in time trouble, but I wouldn't put it passed Bu on a good day. |

| May-17-08 | | Alphastar: <notyetagm: 34 ... Bc5-e3?? was a terrible blunder by Topalov, <LEAVING BEHIND> the e7-square for the devastating <DISCOVERED ATTACK> 35 Nc6-e7+!.> Not true. Here's the analysis done by GM Zagrebelny (as posted by <minasina>): <33 ... Bc5 34.Rc1 Be3! 35.Ne7 Kh7! 36.Rxc8 Rxc8 37.Nxc8 a3 38.bxa3 b3 (pawn irresistible!) 39.Rd1 b2 40.b6 Bc1 41.b7 b1 42.Nd6 with a draw: rook will с1 , And the queen will then announce the eternal Shah on black fields. > |
|
| May-17-08 | | holland oats: Yes, you are right Alphastar...Kh7! is the key move that I overlooked: it prevents the critical knight check in my line (40.Ne8+), allowing black to queen. |

Yet another variation is: <35.Nd7+ Kh7 36.RxR RxR 37.NxR a3 38.b6 axb2 39.Rd1 Bb1 40.b7 b1Q 41.b8Q...> It probably holds the draw, but I do not see a White win. |

| May-17-08 | | LhefrielMedies: In the ICC analysis, the line which Gypsy presented is presented as the primary reason for Bu's rejection of the initial line involving Ne7+. There's no way to stop the pawn from queening. Nick De Firmian offered <39.Rd1 b2 40.Nd6 Bc1 41.b6 b1=Q 41.b7> as winning for white due to the pin on the Bishop and the preoccupation of the queen to watch the b8 square to prevent white from making a queen of his own and just being a rook up. White has the long term advantage due to his extra passed pawn and greater positional freedom, and some immediate compensation in his pawn on the seventh rank. The pinned Bishop is also at some risk. Although, naturally, for the time being, black is a Queen for a Rook and two Pawns, which no doubt gives him a slightly better immediate position, as well as a material lead. It's better for white, but it's the sort of complicated position that Topalov was aiming to achieve, and thrives in, and Bu was right in wanting to avoid it. On move 39, it was obviously a much stronger option as Topalov had already created his passed pawn on the a file, which, unlike the pawn on the b file, could be interfered with, but black had already rejected the line and probably didn't want to revive it again, as black does get a much sharper position with possible counterplay, rather than the consistent white dominance which ultimately won Bu the game. It's clearly better for white in that position, unlike the other one, but after already turning the line down I would doubt that Bu gave it any heavy consideration. As for time pressure... it seems as if Topalov was in some pressure towards the end, inspiring the pointless and losing pawn push the seventh rank to try to reach the time control, but Bu had a reasonable time frame to make the remaining moves. As before, Bu probably rejected the check on e7 to avoid the line which Topalov obviously wanted him to play; clearly, bringing a high class GM into the complicated territory which he's known to play best in isn't the greatest of ideas. It's winning, but it's much more confusing than the simple line which Bu chose, which leads to a slightly more clear superiority for white. |

Bu has rejected Ne7+ because he played to not risk in a won position for White. Certainly, not playing 35.Nd7+ has confused a bit what Black should play in the last minutes, when Topa had few minutes to complete the 40th move. On Gypsy line, after
<35.Nd7+ Kh7 36.RxR RxR 37.NxR a3 38.b6 axb2 39.Rd1 Bb1 40.b7 b1Q 41.b8Q...>
Instead of the regular 41.b8=Q Qf5 +2.70,
with a good White advantage, White has the mate threat in few moves with 41.Ne7! and game is over +7.44,

| May-17-08 | | lentil: can anybody explain why W played 17 Bxe5, instead of 17 de, which seems to win a piece due to the discovered attack on the Q? |

| | Gypsy: < lentil: can anybody explain why W played 17 Bxe5, instead of 17 de, which seems to win a piece due to the discovered attack on the Q? > 17.dxe5 Nd7 ... and Black was a very healthy advantage on the Q-side. |

| May-17-08 | | KarAkter: About 24.Qb5.Watching that game live,and i expected 24.Nd4 or 24.Bf6 with equal or good game for white.Ok,24.Qb5.......but on move 28.Bf3?!(Be3 maybe) black should play simple 28...gf4 29.Bg4 fg3 30.hg3 Rc5 with advantage.So i think maybe 24.Qb5 is not a happiest move for white.And Luzhin have right,32...Bg6 is bad.32...ba3 is certainly better for white. |

|
| Oct-08-08 | | Ladolcevita: Bu's one blazing talent through his rainy days. |
|
| Mar-30-10 | | James Bowman: Bu seems to me, in the few games I have examined, a very nice ability to use his pawns early for an attack that is coming down the road and make them an intergal part of the ensuing attack. Anybody else see this a charecteristic of his play? |

 | | offramp: My BU is the website of Bournemouth University, https://mybu.bournemouth.ac.uk/weba... where Ho Chi Minh was once a chef. Clever pun! |
|
| Aug-24-15 | | kevin86: The rooks line up and attack king from behind. |
|
| Aug-24-15 | | mruknowwho: 40...Rb8 is puzzling. If you feel like you can't stop the pawn, you might as well wait for White to play c6 and then sacrifice the bishop to take the passed pawn off the board. I recommend 40...Ra8. |
|

 | | al wazir: OK, I'll show my ignorance once again. What's wrong with 27...e5 ? If now 28. h3 (28. f3 is much the same), then 28...exf4 29. hxg4 fxg3 30. fxg3 Bc5 31. Kf1 Rcd8. For that matter, in the game line, why not play 30...Bc5+, followed by ...Be3 ? Retreating the ♗ to f8 was very passive. |
