  Calli: Why not 15...Bxd4+

  Honza Cervenka: <Calli><Why not 15...Bxd4+> At first glance it looks quite risky to take on d4 though it is with check. After 16.Kh1 Ne5 17.Rf4 or 16...Rac8 17.Rf4 white seems to win the Pawn back easily and also to get pretty strong attack. I don't know what the comp thinks about this but I would not be happy to get such a position as black.

  Calli: <Honza> 15...Bxd4+ 16.Kh1 Nf6 looks better because if 17.Bxc4? Qc6+ (did Bogo miss this?) and that seems to leave only 17.Bg2 Rac8 etc.

  Honza Cervenka: <Calli> You are right. And even 15...Bxd4+ 16.Kh1 Ne5 17.Rf4 is not so cool for 17...Nd3! though 17.Be4 looks playable. But 16...Nf6 is okay for black.

  Honza Cervenka: Black could also insert 15...e6 before BxP+. If 16.fxe6 fxe6 17.Bg2, then 17...Bxd4+ 18.Kh1 Rxf1+ 19.Qxf1 Ne5 with next Rf8 and Nd3 gives him huge advantage. Alekhine played the opening quite risky and Bogo to his own detriment believed Alexander the Great this bluff.

But 15...Rad8 was not as bad. 20...Rxe3? was a blunder. Bogo simply overlooked that 21.Qg5 attacks Re3 and Bg7 with threatening mate. After 20...Bxf6 black is okay.

  Calli: <Honza> 15..e6 - very nice variation! I didn't think Black had such a large advantage, but apparently Alyeckin did and he left the d4 pawn en prise as a desperate bluff. Interesting!
Mar-04-08  Knight13: 8...Be6?! I don't like that move. Me prefers 8...Nbd7 instead.

The rest is just Bogoljubov getting cut into pieces.

  whiteshark: Two questions:

What's the winning continuation after <19...Rd6>?

What's wrong with <20...exf6>? It looks ugly and queer but is it bad at all?

  Pawn and Two: Fritz indicates Alekhine's advance in the center, moves 7 through 10, was risky, allowing Bogoljubov to gain the advantage.

The next few moves, 11 through 14, were well played by both sides. At move 15, Fritz preferred: (-.91) (20 ply) 15.Be3 Nf6 16.Qe2, but Alekhine played 15.Bxd5.

Bogoljubov then played, 15...Rad8?, and a near equal position resulted after: (-.20) (21 ply) 15...Rad8? 16.Be3, (-.15) (20 ply) 16...Qxb2 17.bxc4 Nb6 18.Bb3. As noted by <Calli & Honza Cervenka>, instead of 15...Rad8?, Bogoljubov should have continued with the strong move, 15...Bxd4+!

Fritz indicates that Black has considerable advantage in this position: (-.98) (21 ply) 15...Bxd4+ 16.Kg2, (-1.08) (22 ply) 16...Nf6 17.Bf3 Rac8 18.Qe2 c3 19.bxc3 Rxc3 20.Bd2 Rc2.

Jul-20-10  aragorn69: Alekhine didn't see it quite that way at the time, but he admits his attack wasn't all that great:

<New York Times, 20 September 1929, page 25 of the sports section:

‘WIESBADEN, Sept. 19 – The seventh game of my match with E.D. Bogoljubow again produced a decisive result – the fourth in succession. Even the most confirmed opponent of the contention that the game of chess is threatened with “death through draws” could not have hoped for such a development in the progress of this match. The more so as the game just decided did not hinge on the victory in the endgame as was the case in the three previous ones. It was a battle full of fire and mutual determination to win.

It was carried on along strictly tactical lines throughout. The battle began when Bogoljubow, apparently dissatisfied with his previous Slavish defense of the Queen’s Gambit, this time elected to play the King’s Indian development, which enabled him to draw his game with José R. Capablanca in the recent Carlsbad tournament.

On my fourth move, by playing a pawn to queen’s five I might have prevented the double advance of his queen’s pawn, a stratagem which Rubinstein employed in the Baden-Baden tournament of 1925. However, I preferred to allow the development in the centre of the board in order to have a more free hand later for manoeuvring by offering my queen’s bishop’s pawn sacrifice, which enabled me to collect a menacing formation of pawns in the centre.

Perhaps the pressure of the white pieces might have been made more promising through a retreat of the knight to king’s bishop three on the 11th move. Because the move of the pawn to the bishop’s five, which suggested interesting complications, enabled Bogoljubow by playing his rook to the queen’s square on his 15th move to evade every possible immediate danger.

In that case the game might have ended in a draw, if on the 17th move he had played the variation leading to an exchange of queens: Queen to bishop six; 18th queen to queen’s knight’s three, bishop takes queen’s pawn; 19th queen takes queen, [sic – add 19th ... bishop takes queen] 20th queen’s rook to bishop’s square and so forth.

Apparently overestimating his position, however, he courted a complicated tactical continuation which, while it netted him a pawn in centre, exposed him to a kingside attack which was difficult to counter. In return for the exchange which he lost on the 20th move as a result of this attack, he temporarily won three pawns which, however, partially weakened him because they doubled and which, because of the attack carried on by the white queen, could only be defended with difficulty.

The rest of the game proceeded with a program in which White was threatening a checkmate and was able to force an exchange of queens and virtually capture all of the opponent’s pawns.

On the 35th move, Bogoljubow resigned the game, which from start to finish kept spectators under a high tension.’>
