The Russian biographer Razuvaev was of the opinion that this was, <"One of Rubinstein's best games!"> I enjoy the simple tactic 19...Nxe4! followed by how easily Black is then able to take the e-file, although White could have prevented that with 24.Qc6 Rubinstein then takes Duras back to school in a fine Rook-and-Pawn endgame. |

| Mar-23-07 | | Eyal: <Archives> Thanks for drawing my attention to this nice game (though I think Razuvaev is exaggerating a bit...). White misses an opportunity to reach a much better position with 19.Qd4+ followed by Nd5. Then, as you mention, 24.Qc6 would have been better (e.g. after 24...Qd4+ 25.Kg1 Qc5 26.Qxc5 bxc5 27.Rae1). Finally, 31.h3? is an unnecessary weakening - after 31...h4! White has to lose a pawn and is probably lost. |

After 19.Qd4+ Qf6 white would have reached a much better position - than he got after the mistake 19.Qg4 but overall the position would have been even. |

If I'm right, it means that 18...a5 was a mistake by Rubinstein, who should have played instead Qf6 or Re8. |

| Jul-14-07 | | Karpova: 19.Qd4+ Qf6 20.e5 dxe5 21.fxe5 Qg5 22.Nd5 Ne6 23.Qc3 b5 24.Rad1 Rad8 looks certainly better for white than the position reached after his blunder but not as if white had a <clear advantage>. It's still quite even. |

For example, Black has 21..Qe7!? 22.Nd5 Ne6! followed by ..Qc5. I don't think White has anything at all in the ensuing endgame assuming a queen exchange and may even have to be careful. But of course this would have been better than what he played in the game, where he almost immediately ended up in big trouble. But <Karpova>'s 21..Qg5 also looks good. |

| Jul-14-07 | | Eyal: <19.Qd4+ Qf6 20.e5 dxe5 21.fxe5 Qg5 22.Nd5 Ne6 23.Qc3 b5 24.Rad1 Rad8> Well, I still think that after 25.b3 it's a ± for White... due to his space advantage and greater freedom of action. A good idea in several lines here would be Qe1 followed by h4, and possibly Be4 (especially if Black doubles rooks on the d file). |

| Jul-14-07 | | Calli: Lasker gave 19.Qd4+ Qf6 20.Qxf6+ Kxf6 and if we continue 21.Nd5+ Bxd5 22.cxd5 is a nice space advantage for Duras. 19.Qd4+ f6 is an arduous defense for Black, but perhaps better than Qf6. |

Lasker wrote in his manual about it:
<In Rubinstein's play the aim against the weaknesses is very important. As the weaknesses vary, he varies his plans accordingly.> |

click for larger viewLasker (again) wrote after 31.h3? in his manual:
<Again White does not consider what and where are his weaknesses. The basis of his defence are the Rook Pawns; to guard them well he should retreat 31.Rdd2. Against 31...Qg4 he had then 32. Rf3, and in any case, though at a disadvantage, he would have made a better fight.> Brilliant!!
Checking with engines, they validate Lasker's estimation... DS10: 2) 31.Rdd2 Qe4+ 32.Qxe4 R8xe4 33.Rf3 a4 34.Rxe3 Rxe3 35.Kf2 Rc3 -0.92/15 J9: 1) 31.Rdd2 Qe4+ 32.Kh3 Qxd5 33.cxd5 Kf5 34.Rc2 R8e7 35.Rfd2 g5 36.fxg5 Kxg5 37.Rc4 Re1 -0.62/18 Rybka232: 1) 31.Rdd2 Qxd5+ 32.cxd5 Kf5 33.Rf3 Re2+ 34.Rf2 Re1 35.Kh3 R1e3 36.Rc2 R8e7 37.Rc6 h4 -0.37/23 |

| Dec-08-10 | | Rama: What about 30. Qxf5 gxf5, 31. Kh3 Kf6, 32. Kh4 a4, 33. b4 ... ? The K-side is locked up, the black K cannot get to the Q-side, and the 2nd rank is secure. |

 | | tamar: <Rama: What about 30. Qxf5 gxf5, 31. Kh3 Kf6, 32. Kh4 a4, 33. b4 ... ?> Black has 31...h4! when 32 Kxh4 is taboo because of mate on the h file.
So 32 Kg2 hxg3 33 hxg3 Rc3! and Black is threatening to double on the third rank. |

 | | Sastre: <tamar> There is no mate after 30.Qxf5 gxf5 31.Kh3 h4 32.Kxh4 Rh8+ 33.Kg5. |

| | tamar: My error < Rama> + <Sastre> You are correct. The Black King is still on g7, so there is no mate threat. Getting back to Rama's question, Black has to look for other weaknesses if White's King manually blocks the h pawn advance. <Rama: What about 30. Qxf5 gxf5, 31. Kh3 Kf6, 32. Kh4 a4, 33. b4 ... ? The K-side is locked up, the black K cannot get to the Q-side, and the 2nd rank is secure.> 
click for larger viewInteresting. Black at first looks to have good winning chances with 33...Rc3 34 Rd4 Re4 35 Rxe4 fxe4 but after 36 Kxh5 it is still a pawn race which would take considerable analysis to see if Black has a win.

| Dec-08-10 | | Rama: Exactly, it will devolve into a R+P ending with each side having a majority. ♖ubinstein could win it if anyone could, I suppose. I'm having a lot of fun going through the St Pete '09 tournament. |

| Jun-18-21 | | tbontb: As noted above, after 31.h3 (better Rdd2 when Black maintains a small edge) ....h4 undermines the White K-side and wins at least a pawn. Later Kd4 loses further material, leaving a "simple" technical win. |
