|Nov-09-05|| ||Cecil Brown: This game is over my head. A whole mess of tactics and a very strong positional queen sacrifice. |
I can see the idea of 15.Rxd5 as 15..Nxd5 16.Nfxd5 Bxd5 17.Ncxd5 traps the queen. 14.Bb6 is preparing the trap of course.
After 23.Qxb7 black only has Rook and two pawns for the queen but has some terrific positional compensation. White's king position is terribly weak and his kingside totally undeveloped.
One of those GM games that shows the difference between them and us.
|Nov-09-05|| ||Cecil Brown: Hmmm. Is 22.Nf6+ better than Ne7+? It opens up blacks king and might give white some more counterplay later on.|
|Aug-18-06|| ||moiz: I agree, Cecil, sets the boys apart from the men.|
|Aug-18-06|| ||psmith: <Cecil Brown> Looking at this with Fritz 5.32 it seems 22. Nf6+ leaves Black's Bishop on c5, blocking White's flight square at e3, and makes Black's job easier. Thus after 22... gxf6 23. Qxb7 Rfa8 White pretty much has to play 24. Qxa8 when after 24... Rxa8 25. exf6 d5 Black is better.|
In contrast in the game continuation White had some chances. In particular it seems that 24. f4 was a mistake, giving up two pawns for no good reason. Better appears to be 24. Kd1. The best that Fritz and I can then find is a draw after 24... Rfa8 25. Ke1 Bd2+ 26. Kf2 Bxc3+ 27. Ke3 Bd2+ 28. Kd4 c3 29. Bd3 R2a4+ 30. Kd5 Be3 31. Re1 Bf2 32. Re2 Bg1 33. Re1 Bf2... But this is complicated so I'm not sure.
|Aug-18-06|| ||Manic: apparently some consider this queen sac "theory," even though its only be played in two games i think, this and the other one being lalic vs khalifman linares 1997. Khalifman played h4 instead of na6|
|Aug-18-06|| ||Longbrow: Black seized the tempo and never let go. This is a nice game.|
|Aug-18-06|| ||weary willy: <Manic: apparently some consider this queen sac "theory," even though its only be played in two games i think, this and the other one being lalic vs khalifman linares 1997.> |
... interesting point ... in chess, I think we use "theory" to mean "practice" ... or would you restrict the description to published (but unplayed?!) analysis?
|Aug-18-06|| ||psmith: <Manic> <weary willy> The database shows that the Queen sac in this line (not in this exact position) has occurred at least two other times (and there may be games not in the chessgames database):|
W Schubert vs H Kruse, 1999
A Allemann vs R Costantini, 2001
So, we can say that this is a theme in the opening anyway.

well, a full nelson is a tie knot, and a very tough one. kudos for the choice of the game and the pun, cg.com.|
|Aug-18-06|| ||RandomVisitor: 21.Kd1 and Rybka scores the position 1.54/24.|
|Aug-18-06|| ||Peligroso Patzer: < Cecil Brown: This game is over my head. A whole mess of tactics and a very strong positional queen sacrifice. >|
I agree. This was a game replete with tactics right to the end. Playing through the moves quickly the first time, I expected Black's 33rd move to be 33. ... Rea8? On closer inspection, I realized that this move would have been a terrible blunder since (if 33. ... Rea8?) White is back in the game after 34. Bxc4.
|Aug-18-06|| ||The17thPawn: The Benko strikes again. Anybody know a positional line for white against this monstrosity? The tactical route seems to land white in difficulties as often as not.|
|Aug-18-06|| ||dbquintillion: What's interesting, with regards to this queen sacrifice, is that in the other two games cited its not really a pure sac. In those two, black gets adequate compensation (rook + minor piece + pawn in one game, three minor pieces in the other). However, black does not manage to win either game. Here, the sacrifice is purely positional and gives up material equality but black wins. Very interesting game.|
|Aug-18-06|| ||kevin86: An outstanding game!! Black sac a queen for a rook and ends up ahead----mainly because white's bishop and rook are still tied in the stall.|
The king is in a trap--and will be rounded up by the two rooks and a pair of helpful pawns-one white,one black.
|Aug-18-06|| ||weary willy: The pun is mightier on the board: <a full nelson is a tie knot, and a very tough one> .. I think it's actually a wrestling move ("hold"? "throw"? "technique"?.|
... as opposed to a Brown Windsor, which was used by the late Edward VII (who, in 1938, resigned in a winning position) to keep his tie out of his soup
|Aug-18-06|| ||MikeChesss: Games like this are probably too far over my head to help me develop. I doubt I would ever try a queen sac unless I could see a clear path to a mate. Am I the only patzer, or do others agree?|
|Aug-18-06|| ||dakgootje: Great game-pun combination!|
|Aug-18-06|| ||fxenderby: <weary willy> yeah.. guess you're right. i was thinking about the full windsor.. that's the stuff fools are made of! and tell again that soup story..! :)|
|Aug-18-06|| ||oao2102: Bravo to <jcmoral> for submitting this game.|
|Aug-18-06|| ||rjsolcruz: i am just wondering on why was gm mariano not in the rp team in the olympiad considering that he is 1 of the 5 living gm's?|
with games like these, points will just keep on popping up.
|Sep-07-06|| ||patzer2: Black's Tal-like Queen sacrifice 15...Qxc3!? in this Benko Gambit declined may not be completely sound, but it created enough complications in this game to beat a strong GM.|
White's best chance to hold the position for some winning chances appears to be <Rv>'s 21. Kd1! . However, IMO even here White's winning chances remain unclear.
White also missed chances to hold with 24. Kd1 and 26. Qd5 =.
After 26. Ke1?? Bxe5 it appears to be a win for Black.
In any event, the attack and White's potential defenses are worthy of examination.
|Jan-24-07|| ||whatthefat: A similar position in this queen sacrifice line arises after 14...h5 15. Rxd5 Qxc3+ 16. bxc3 Nxd5 17.Qe4 Ba3+ 18.Kd2 Nxb6 19.Qxb7 Bc5 20.Nd5 Rxa2+ 21.Kd1 0-0 22.Nxb6 as in A Allemann vs R Costantini, 2001|
And now after 22...Bxb6 23.Qxb6 Nc6 (as recommended by Neil McDonald in 'The Benko Gambit Revealed') this position would be reached:

As in the above game, White has queen for rook, but the fragility of his king's position at least practically compensates, if not objectively. The position is difficult to win for White OTB, even for a very strong player, while Black has serious chances to win.
