Jun-21-06 | | Ybrevo: One of the most interesting Sicilian games I´ve seen for a long time - far away from the orthodox and well-known lines. The final position is a real beauty! |

 | | Mateo: A deceptive loss for Volokitin. I think Rublevsky's attack would have proved to be rather speculative against a better defence. 1. e4 c5 2. Nc3 d6 3. Nge2 Nf6 4. g3 b5 5. Bg2 Bb7 6. d4 b4 7. Nd5 Nbd7 <The US IGM W. Browne played 7...Nd5 here, but lost> 8. O-O e6 9. Nxf6+ Nxf6 10. d5 exd5 11. exd5 Be7 12. h3 O-O 13. g4 Nd7 14. Ng3 g6 15. Bh6 Re8 16. Re1 Bf6 17.

Better 29...Kh8 30.Be5 de 31.Qe5 Kg8, Black is okay> 30. h4 Kh8? <Bad and even losing. This not a better place for the King, since Black will have problems along the diagonal a1-h8, and this move does nothing to impede h4-h5. He should have played 30...Be2 > 31. Bxd6 f4 <31...Qf6 impeding White's next move seems better. But 32.Bc5 (32.h5 f4!) f4 (32...Qh4 33.Qc7 Qh6 34.Be3 f4 35.Bd4 Kg8 36.Qc6 wins) 33.Qb3, threatening 34.Bd4 and 34.Qa4 gives White an overwhelming advantage> 32. Qg5 f3 33. Bh3 h6 34.

Jun-24-06 | | patzer2: Rublevsky's positional exchange sacrifice 25. Ne6! appears to be made more out of necessity for defensive purposes than as a calculated attacking move. Even so, it is the strongest move in the position and a good example of using an exchange sacrifice to create complications to defend a difficult position. Black's best chance to maintain a clear advantage, with little or no danger of losing, IMO would have been with 27...Bc4! or 27...Rc8 . Missing these opportunities, Black slipped into an inferior position with 30...Kh8?, (missing 30...Be2= as noted by <Mateo>). |

Jun-24-06 | | acirce: <Rublevsky's positional exchange sacrifice 25. Ne6! appears to be made more out of necessity for defensive purposes than as a calculated attacking move. Even so, it is the strongest move in the position and a good example of using an exchange sacrifice to create complications to defend a difficult position.> I completely disagree. 25.Ne6 seems to fit right in with White's aggressive plans, not some kind of more or less desperate measure to "maximize resistance". Probably Black could have put up a better fight with moves such as the computer-recommended 27..Bc4, but when you look at the position <little or no danger of losing> seems quite absurd. In any case such moves are hard to find. But after 28.Qg5 it still seems very unclear, although I'd favor White's chances in a practical game. |
|
Jun-24-06 | | acirce: As <Mateo> says, if 29..Kh8 in the game Black should also be ok, although hardly better. Still all three results possible I'd say. |
|
Jun-25-06 | | patzer2: <acirce> I also first thought 25. Ne6 was a calculated move as part of an "agressive plan." However, a long look at the position and the possibility 27...Bc4! with Fritz 8 convinced me otherwise. Of course if by an "aggressive plan" you means the strongest active defense to try for a swindle or a draw in a bad position, I would agree. However to suggest this move was purposely calculated in advance as part of a plan to gain an advantage is a stretch, and is not IMO supported by an objective analysis of the position. After <25. Ne6 Bxe6 26. Qxe3 Qf7 27. gxf5> 27...Bc4! White is fighting to hold the draw and Black has all the winning chances. Fritz 8 gives the main line as continuing 28. Qg5 a5 29. f4 Nd7 30. Be4 Qf6 31. Qg2 Qa8+ 32. Kh2 Qf1 (-1.91 @ 15 depth, Fritz 8) when White is busted. If as you say, you'd favor White's chances in this position, then give some analysis to prove it. I would welcome an improvement showing White has any winning chances against best play after 25. Ne6. |

Jun-25-06 | | acirce: <However to suggest this move was purposely calculated in advance as part of a plan to gain an advantage is a stretch> Not necessarily calculated in advance, but I definitely think he was ready to give away an exchange if necessary in return for such an initiative on the kingside. Risky for sure, but still. <After <25. Ne6 Bxe6 26. Qxe3 Qf7 27. gxf5> 27...Bc4! White is fighting to hold the draw and Black has all the winning chances.> I just don’t understand how you can look at the pieces swarming around Black’s king – and the passed pawn, not to forget - and claim that White has no winning chances. Not necessarily that he has an objective advantage, but that he has significant practical chances. Against ”best play” I don’t think he would win. That’s not the point, since it’s very difficult to play such a position from the Black side. This is why I said I favor White’s chances <in a practical game>. Certainly he could have lost too.
After 28.Qg5, Fritz 8’s suggestion 28..a5 is a strange move doing nothing to counter White’s attacking possibilities. What do you play on 29.Be4 ? If you do nothing I will, perhaps, continue with the slow 30.Qg3!? intending fxg6 followed by f4, h4 or Qxd6. Even 30.f4 right away is interesting. But Black probably plays 29..Qxf5!? (30.Bxf5 Nf3+) and then 30.Qe7 Qf7 (only move) 31.Qxd6 Nd7 (only move) and then maybe 32.Qc6 and a machine is perhaps able to defend but it’s much harder for a human. There are many different tries for both sides but this kind of position is generally more difficult to play for the defender. |

Jun-25-06 | | patzer2: <acirce> I must admit after 27...Bc4! 28. Qg5 a5 29. Be4! (overlooked in my initial analysis with Fritz 8), White can apparently with "best play" hold the position with equal chances or better -- and also with good "practical chances" as you suggest. I was initially concerned with all the pieces swarming around the Black King, but like in football (soccer) with too many players pushed forward attacking the opponents goal, I thought White might be vulnerable to a counterattack. However, in this case the counterattack appears to be only a difficult defense for Black to draw as you suggest. Good insight and analysis. As always I appreciate your strong analysis and insight. Thanks again for finding the improvement in this line and good luck in your games! |

 | | tamar: Golubev says Black's 7th move already was new.
Rublevsky reponded by building up with the ambitious g4 and Ng3-e4, but had to allow Volokitin great piece play in the meantime. White's attack is not likely to be repeated exactly like this in the future. There are too many ways for Black to defend after 25 Ne6. The skeptical 25...Qa4 suggested by Shredder 8 looks hard to crack, as Black feasts on the c2 pawn, saying in effect, where is the winning attack? Instead Volokitin "believes" Rublevsky, and puts his queen on f7, and adopts a defensive posture. |

I think after 27... Bc4 White is lost with best play but I agree with acirce when he says that White had practical chances of winning. Specially considering the time control used in this tournament. |
|
Jun-25-06 | | patzer2: <Hesam7> Your analysis of 27... Bc4 28. Qg5 Re8! looks sound, and restores my faith in 27...Bc4! as a winning try for Black. <acirce> What do you think? It appear to me that <Hesam7>'s line puts White on the brink of losing after 27...Bc4, and makes White's exchange sacrifice look a bit too risky. |
|
Jun-25-06 | | patzer2: <Hesam7> I see you don't see a clear advantage for Shredder's 26...Qa4, as mentioned by <tamar>. Do you see 25...Qa4 an improvement, or does it run into similar complications? Personally I prefer the game continuation with your recommended 27... Bc4! 28. Qg5 Re8! because it's a safer and simpler plan for a human to understand and carry out (i.e. shore up the position, exchange off Queens, win the endgame). |
|
Jun-25-06 | | Hesam7: <patzer2>, <tamar> Sorry, I made a mistake. I thought <tamar> was talking about 26... Qa4, which is bad compared to the game continuation as I showed. I have not looked at 25... Qa4 yet. |
|
Jun-25-06 | | TaricHall: unbelievable game! Interesting use of bishops;) |
|
Jun-25-06
 | | tamar: <patzer2 and Hesam7> 25...Qa4 is the proposed move, improving upon 25...Bxe3. It is hard to say if this-removing the queen from the King's area- is more difficult for a human to visualize than alternating defense ...Qf7 with skirmishing moves ...Bc4. Tarrasch did pretty well with all queenside play versus a Kside demonstration in Pillsbury vs Tarrasch, 1895
until he froze up and played a few purely defensive moves. I'll post some analysis tomorrow about the 25...Qa4 26 Nxc5 line. |
|
Jun-26-06 | | Hesam7: It looks like 25... Qa4 is a direct refutation of Rublevsky's idea. Here are some lines, I got with my engine: 25... Qa4 26. gxf5 Qxc2 27. Nc7 Bxe3 28. Qxe3 Qd1 29. Kh2 Qh5 30. Qg5 Qxg5 31. Bxg5 Bb7 32. Nxa8 Bxa8 33. Be7 Nf7 34. fxg6 hxg6  25... Qa4 26. Nxc5 Bxe3! 27. Qxe3 Qxa2 28. Bf4 Nf7 29. Nxa6 Qxa6 30. gxf5 Qa1 31. Bf1 gxf5  |
|

 | | tamar: 25...Qa4 may be necessary to prevent what happened in the game. Given a few moves, as <acirce> showed in earlier posts, White can involve the bishop and even set up pawn pushes f4 or h4 h5 similar to the game. So if there is a refutation of Rublevsky's attack, it must come between moves 25-28. Here is one of Shredder's lines, getting just enough attack to defuse White's build-up. 25...Qa4 26 Nxc5 Bxe3 27 Qxe3 Qxa2 28 gxf5 Qa1+ 29 Kh2 Bf1 30 Bxf1 Qxf1 31 fxg6 hxg6 32 Qf4 Qe2 33 Ne4 Qf3 -3.40/15  click for larger viewif now 34 Qh4 Qh5 and the shadowing continues.

Jun-29-06 | | patzer2: <Tamar><acirce> Thanks for your analysis. It's good to have Expert and Master insight and analysis in looking at this difficult position. I suppose <acirce> was probably correct in suggesting the exchange sacrifice was a good practical try in a complicated position. Yet 25...Qa4!, which few strong human players would likely have had the courage to try, does indeed seem to make surviving with a draw difficult if not impossible for White. |
|
Jun-29-06
 | | tamar: <patzer 2> 25...Qa4 looks outlandish, but <keypusher> has a funny note on the Winawer vs Lasker, 1896 page that I think applies: <Should be in every beginner's manual -- sometimes taking your queen on a "wild-goose chase" after a distant pawn is the right way to play!> |
|
Jul-01-06 | | hitman84: This is a real beauty of a game by Rublevsky.
This game shows how strong a stenitz outpost for a N really is!
black's a6 B never came into play.
Thanks for the analysis everyone. |
