 | | beatgiant: White appears to have a big positional advantage in the early middlegame, but Black turns it around with tactical counterblows. What does Black have on 21. ♘bxc7 instead of the mysterious 21. ♗c1 ? |
|
| Sep-11-04 | | Leviathan: <beatgiant> after 21.Ndxc7 white is perfectly fine. After that, black can start some kind of counter-attack with 21. ... Rh6, but white can defend himself easily. For example: 22.h3 Nh4+ 23.Kh2 Nf5 24.Qf3 a4 25.Rd3 Bxc7 26.Nxc7 with a winning position. |

| | beatgiant: Another possible improvement is 22. f3 instead of the game's 22. ♘f4 . Then after running a gauntlet of tactical threats, White still may emerge with some positional advantage. For example, 22. f3 ♘h4+ 23. ♔f2 ♕h3 24. ♔g1 ♖fe8 25. ♖f1 ♘g6 26. ♖df2 ♖e1 27. ♗d2 ♖xf1+ 28. ♕xf1 ♕d7 29. ♖e2 . |

| | beatgiant: It looks like 24 h3 ♖h6 25. ♔g2 ♖xh3 26. ♘xh3 ♘h4+ 27. ♔h2 ♘f3+ leads to a draw by perpetual check. Maybe White was still playing for a win here, although I'm not sure he has the advantage anymore. |

| Oct-01-04 | | percyblakeney: The black bishop on b8 isn't looking very active, standing there from move 19 to 35... Fritz (who agrees with Nimzowitsch on 21.Bc1) sees 22.f3 as the best move, one line is: 22.f3 Qg6 23.g4 Nh4+ 24.Kg3 Qg5 25.f4 Qd8 26.f5 Ree8 27.Rf2 g5 28.fxg6 fxg6, evaluated +3.12. |

| | beatgiant: <Fritz (who agrees with Nimzowitsch on 21.Bc1)> Does this mean Fritz does see a way for Black to get compensation for the pawn after 21. ♘bxc7 ? Or it believes the positional advantage is worth more than a pawn? |
|
| Oct-01-04 | | percyblakeney: Fritz thinks white is clearly better after taking on c7 as well, but not as much better as the positional advantage makes it after Bc1 and f3, the latter seems to be the key move. |

| Dec-21-05 | | lopium: Well, Capablanca was maybe the best end gamer, but here Alekhine seems perfect to my eyes. |

 | | Pawn and Two: Fritz 9 at (19 ply) (favoring White +1.34) recommends 21. Nb5xc7 (or Nd5xc7) Re6-h6 22. h2-h3 Bb8xc7 23. Nd5xc7 Nf5-h4+ 24. Kg2-h2 Nh4-g6 25. Qd3-f3 Qg5-e7 26. Nc7-d5. Fritz rates Nimzovich's move 21. Bc1 at (19 ply) as favoring White by only (.61) and suggests the following line: 21. Bb2-c1 Qg5-g4 22. f2-f3 Nf5-h4+ 23. Kg2-f2 Qg4-h3 24. Kf2-g1 Rf8-e8. Both Fritz and the tournament book agree that correct for White is 24. h3! Rh6 25.Kg2 Rxh3 26. Nxh3 Nh4+ 27. Kh2 and leads to a draw. |

| Jun-17-11 | | dull2vivid: I have the feeling (could be totally wrong) that these two masters just wanted to show off, and that meant not taking material when some was offered and offering material for illiquid compensation. I see vanity in the erroneous moves. |
|
| Jun-18-11 | | aliejin: "I see vanity in the erroneous moves."
Alekhine wrote "Chess is vanity !" |
|
| Feb-18-13 | | Ulhumbrus: Instead of 17 Rfd1, 17 f4 grabs space. It may be mistake to wait for Black to play ...Nf5 followed by ...Qg4 and ...Nf5-h4-f3 |

Stockfish however rates 20 Nd5 1.57/29 as best. |

| Jan-02-14 | | Calli: Engines and other annotators disagree.
After 20.Nd5 Re6 White can safely take the pawn 21.Nbxc7 Alekhine simply annotated 21...Rh6 here as if he was fully compensated for the pawn but the attack goes nowhere after 22.h3! BxN 23 NxB Nh4+ 24.Kh2 Ng6, for instance.

White always has Qf1 to protect h3, Bc1 is coming etc. In short, Nimzo could have won. |

So Houdini 3x64 prefers Nimzovich's suggestion. ...> This suggests that if Nimzovich considers the overprotectors - the rooks - to be placed well we have to ask in which ways Nimzovich considers them to be well placed and then whether Houdini confirms that they are placed well in these ways |

| | tamar: Alekhine was a demon at Baden Baden, and it appears Nimzowitsch allowed himself to be bluffed. Probably White's position is so good that both 20 Nd5 and 20 Re2 are winning, simply because of the terrible bishop on b8. The lines with 20 Re2 look easier for a human to control, and it is natural afterwards to think of ways to stop the particular attack Alekhine adopted. |

 | | plang: 4..Nge7 had been played once previously; 4..d6 was new. 15..Rae8 was important because if the queens are exchanged on f5 White is unable to play Nd5 due the knight on e2 being unprotected. Nimzovich thought that, after 19..Bb8, he should have transferred his rooks to the e-file. |
