Kibitzer's Corner
May-23-06  ArturoRivera: 5.-...c5 its a bad move, allowing white to play an inmidiate d5, and the Bb7 its out of play, bad move from Bogoljubov.

16.-Be4! its typical from Alekhine. BLack's position collapses. For example, after the natural 16.-...h6 then we have 17.-Bxh6! gxh6 18.-Rg5+! hxg5
19.-Qh7 mate

or as well
17.-Bxh6 f5
18.-Qg5 Rf7 (forced)
19.-Rxf5! Bxe4
20.-RxR KxR
21.-Qxg7+ Ke6
22.-Rd1 in a variation where white has three passed pawns for the piece and the king its stucked in the center, and all white's have to do its advance his FOUR PASSED KINGSIDE PAWNS to win. He may even go to an endgame voluntarily. how you stop four passed pawns?

if 18.-...Qc7? then we have
19.-Bxg7! Qxg7
20.-QxQ KxQ
21.-Rd7+! and black's position collapses.

17.-...Nxd5 fails due to Bxg7 treathing mate on h8 and the treath of Qh7 mate.

I am surprised no one has ever kitbitzed this Alekhine Brilliancy

May-23-06  Hidden Skillz: maybe because he had too many to name ^^
May-23-06  ArturoRivera: I always tought Alekhine sucked, and i got this recoiplation of his games...the guy is Tal's grandpa. All games he sacrificed something, its amazing!

  Pawn and Two: Alekhine stated that Black's loss in this game could be attributed to his move 5...c5. He indicated that after 5...c5 6.dxc5, White will secure the advantage due to the pressure he exerts on the open Q file.

Analysis by Fritz indicates that while White has some advantage after 5...c5, it does not appear to be decisive.

Alekhine indicated the correct continuation was 5...Be7 6.0-0 0-0 7. Nc3 d5 8.Ne5 Qc8, with a satisfactory game for Black. Fritz evaluated this position as slightly in favor of White: (.58) (20 ply) 9.cxd5 Nxd5 10.Nxd5 exd5 11.Bf4 Qe6 12.Rc1 Bd6 13.Nd3 Nd7.

Instead of 5...Be7, Fritz preferred (.32) (21 ply) 5...Bb4+ 6.Bd2 Qe7 7.0-0 0-0 8.Nc3 d6.

In addition, Fritz indicated that both 5...c5, and 5...Be7 are playable for Black: (.43) (21 ply) 5...c5 6.d5 exd5 7.Nh4 g6 8.Nc3 Bg7 9.0-0 0-0, or (.46) (21 ply) 5...Be7 6.Nc3 0-0 7.0-0 Ne4 8.Qd3 Nxc3 9.Qxc3 d6.

  Pawn and Two: Alekhine stated that 8...d5 allowed White the opportunity of unmasking his KB with advantage. He recommended 8...Na6 instead, and indicated that Black's QP would also be weak in that line.

Fritz indicated the position was nearly equal and recommended: (.17) (21 ply) 8...Qe7 9.a3 a5 10.Na4 d6 11.Bd2 Na6 12.Qb3 h6.

Fritz indicated the move played, 8...d5, was also very acceptable: (.20) (21 ply) 8...d5 9.cxd5 Nxd5 10.Qc2 Nxc3 11.bxc3 Qe7.

Alekhine's recommendation of 8...Na6, was also playable for Black: (.29) (21 ply) 8...Na6 9.Bf4 d5 10.Ne5 Qe7 11.cxd5 Rfd8.

  Pawn and Two: Alekhine indicated Black played 9...Bxd4 to allow the possibility of ridding himself of the troublsome QP. However, Alekhine points out this move allows White the advantage of the two Bishops. In this position, he stated, it implies a marked superiority for White.

Alekhine gave an alternative line for Black: 9...Nc6 10.Nxc6 Bxc6 11.Bg5 Be7 12.Rc1, but suggested it was hardly more attractive.

Fritz indicated that White has a small advantage after 9...Bxd4: (.35) (20 ply) 9...Bxd4 10.Qxd4 Nc6 11.Qh4 Ne5.

However, Bogoljubov should not have played 9...Bxd4. It may not give White a decisive advantage, but deeper evaluations by Fritz show White's advantage increasing above the indicated (.35) (20 ply).

Instead, Fritz preferred: (.08) (20 ply) 9...Qd7 10.cxd5 Nxd5 11.Nxd5 Bxd5 12.Nb3 Be7 13.Bf4 Bxg2 14.Qxd7 Nxd7 15.Kxg2, with about an equal game.

Fritz also found Alekhine's alternative line, with an improvement at move 11, to be playable for Black: (.24) ( 20 ply) 9...Nc6 10.Nxc6 Bxc6 11.Bg5 Rc8 12.cxd5 exd5 13.Bxd5 Bxd5 14.Bxf6 Qxf6 15.Qxd5 Bd4.

  Pawn and Two: Alekhine stated that Black played 11...dxc4 in the hope White would reply 12.Qxc4. Alekhine then indicated Black could play either 12...Ne5 or 12...Na5 with an approximately equal game. Fritz confirms that 11...dxc4? 12.Qxc4? Na5! 13.Qb5 Bxg2 14.Kxg2 Rc8 is approximately equal.

However, White played the much stronger 12.Rd1!.

Fritz confirms that 11...dxc4? was an error: (.69) (22 ply) 11...dxc4? 12.Rd1 Nd5 13.Bg5 Qc8 14.Be4 f5 15.Bxd5 exd5, and Black has a very difficult position after 16.Rxd5! Qe6 17.Rad1.

Black's best move, with a much better chance for a successful defense was: (.44) (22 ply) 11...Ne5 12.cxd5 Nxd5 13.Qh5 f5.

  Pawn and Two: At move 14, Alekhine could have tried 14.Be4. Fritz then indicates the following line was likely: 14.Be4 f5 15.Bxd5 exd5 16.Rxd5! Qe6 17.Rad1. The resulting position is very difficult for Black. His best try may be 17...Ne5, but White can keep the pressure on with 18.Rd6.

Instead of this variation, Alekhine tried 14.Nxd5 exd5 15.Rxd5. At this point Bogoljubov erred by playing 15...Nb4?.

Alekhine stated regarding 15...Nb4, <It is clear that other replies would be no better.>

Alekhine is mistaken at this point, as Fritz has found a much better defense for Black: (.49) (22 ply) 15...f6! 16.Be4 f5 17.Bc2 Qe6, or if 17.Bf3 Nb4, or 17.Bg2 Nb4, and Black still has a reasonable chance for a successful defense.

  Pawn and Two: After Bogoljubov's error 15...Nb4?, Alekhine played 16.Be4!.

Alekhine states 16.Be4! was decisive. He notes, <other variations would be no better>, and then he gives the following variations: 16...h6 17.Bxh6 f5 18.Qg5 Qc7 19.Bxg7 Qxg7 21.Rd7+; or 16...g6 17.Bf6 Nxd5 18.Bxd5, and White wins.

However, there was one reasonable try left, and Bogoljubov in a losing position certainly should have played it.

After 16.Be4!, Black lost quickly after 16...f5?.

Instead Black should have tried 16...h5, and if White was careless and played 17.Qxh5??, then 17...f5! 18.Rd8 Rxd8 19.Bxd8 fxe4 20.Qxe8+ Kh7 21.Qh5+, and the position is equal.

Of course, Alekhine would have spotted the trap, and probably would have responded to 16...h5 with 17.Rd4 Bxe4 18.Rxe4 f6 19.Bd2 Qf5 20.Rxc4 Na6, and White has a winning endgame. In any case, 16...h5 was Black's best move, and although in a losing position, it was a far superior choice to the move played, 16...f5?.

  whiteshark: <Pawn and Two> Thanks for your fine analysis!

Isn't it curious that AA didn't mention <16...h5> in his annotations?

  shalgo: 16...h5 is clearly the best move in the position, but it isn't surprising to me that Bogoljubov didn't see it during the game and that Alekhine didn't consider it during his analysis. After all, it is completely counterintuitive: it hangs a pawn and seemingly only delays the mating threat on h7 by one move.

Once you look at it, its merits are clear, but I know that I, for one, would never even consider it in the first place.

Also, by the way, <Pawn and Two>'s final position after 20...Na6, while clearly better for White, is not a winning endgame. For one thing, each side has queen, two rooks, and a minor piece, so it is not an endgame at all. White does have an extra pawn and bishop versus knight in an open position, and therefore must be winning with correct play, but his pieces are awkwardly placed and he must be careful to consolidate.

May-05-09  WhiteRook48: 18 Rd8+!!

20. Bxb6! Missed 3 times!

If 20.Rxb6 and black recaptures with the pawn then the piece winning Qe7, the Bishop or knight fall and it more or less wins the game... White had 3 chances!

  zanzibar: This is G55 in the Dover ed. (BG 1908-1937), p137, and Alekhine cites a Brilliancy Prize for this game.

Maybe when I do this tournament I'll try to find money award.

Chessical notes Alekhine's comment that 16.Be4 was decisive, but note Alekhine gives it !!, as compared to Chessical's single !.

There were two high-level tournaments in Triberg in 1921. The first was in July, and includes this game. The second was a 4-RR4 in December. <CB> refers to them as Triberg_A and Triberg_B.

Alekhine participated in both, but was a director for Triberg_B.

There was also a match between Alekhine and Bogo in Triberg in 1921. <CB> refers to it as the <Triberg Secret m>.

Jan-26-18  Retireborn: <z> I'd certainly be interested to learn more about these two tournaments. One notes that Bogo and Selezniev played in both of them, and wonders if they lived there at the time, or if they or their backers put up the money etc

Chessbase gives a precise start date (5.12.1921) for the B-tournament, but 11 of the 24 games are just stubs.
