  Chessical: <CapablancaRules> These are the program's evaluations of the position in terms of pawns; a negative score showing a disadvantageous position for the player.
Dec-25-03  Lawrence: Chessical, if I may rephrase your explanation I'd say "A positive score shows an advantageous position for White, a negative score shows an advantageous position for Black."

CapaRules, if you haven't got Fritz, Shredder, Junior, Hiarcs etc. I'd earnestly suggest you get one. Just a few days ago I learned how to load chessgames into the computer--I had been laboriously copying them out by hand and putting them in!!--and it's so quick, and so fabulous to have every move analyzed at GM level, that now I just automatically load every game I study into Junior.

May-20-04  mtatewaki: 16.g4? is a mistake, 16.Qf7 was winning, for example: 16...g6 17.g4 qe3 18.kg2 gf5 19.g5 kg5 20.qg7 kf4 21.rf1 ke5 22.qe7 kd4 23.rd1 kc4 24.qe6 kc5 25.b4 kb4 26.qb3 kc5 27.qb5 mate.
Sep-17-04  Sergey Sorokhtin: Look new Kasparov's very detailed correktion this game!

http://www.chesschamps.com/pgn.shtml

Jul-01-05  DWINS: From "Combinations:The Heart of Chess" by Irving Chernev.

"Rarely did Capablanca miss the quickest way to win, no matter how complicated the position. At the conclusion of his game with Bogolyubov, Capablanca pointed out this magnificent combination which could have ended their exciting struggle in a blaze of glory:

26.Rh3+ Kg4 27.Kg2! Nxe4

The alternative is 27...Nc5 28.Nh6+ Rxh6 29.Rxh6 Ncxe4 30.Nxe4 Nxe4 31.h3+ Kf5 32.Rd5#

28.Rd5! Nxc3 29.Rh4+! gxh4 30.Nh6+! Rxh6 31.h3#! 1-0

Sep-26-05  CapablancaFan: Here's an interesting game by Capablanca. In this game Bogoljubov dosen't even get to complete his opening before Capa has already sacraficed a piece by move 9! Bogo's King is suddendly flushed out in the open complications arise and as usual Capa's straight no-nonsense play cuts through the gridlock and Bogo soon turns down his King. Further proof that even in the opening mundane positions you could'nt take Capa lightly!
Dec-14-05  DeepBlade: Remarkable
Move 10: Capa sacs his Bishop, to recapture with his Knight, and attacking the Queen (developing while attacking something rule). Capa plants the Shotgun type (its moving pattern) Knight in Blacks camp.

Move 11: Capa waits for Black to take his Bishop so he can recapture with his pawn in front of his Rook, thus activating it on the semi-open f file.

Move 17: Exhanges the Queens, disables mate prevention by Queen, also nice timing, so the lesser pieces may reign.

Move 19: Capa has enough of this, with snowball effect (first a little snowflake sliding of the mountain, until its to big to be stopped) he pulls of his mating combination.

Dec-21-05  Norman Glaides: Edward Winter has just put up a lengthy article on this game here: http://chesshistory.com/winter/extr...
Aug-09-06  Gouki: why didnt Bogoljubov take the knight after, 18.Rd1 gxf4?

  InspiredByMorphy: <Gouki> 18. ...gxf4 19.g5+ Kg6 20.gxf6 fxe3 21.Nd5 appears to give white a positional advantage.


click for larger view

White threatens 22.Ne7+ Kf7 23. Nxc8 Raxc8 24.Rxd7+ and if black plays 21. ...Nc5 then 22.Ne7+ Kf7 23.Nxc8 Raxc8 24.Rad6

Aug-09-06  Boomie: <Gouki> Bogo was in time trouble. Taking the knight or Ra5 are winning moves for black.
Aug-09-06  Boomie: <Gouki and Inspired> To expand on my last post:

18...gxf4 19. g5+ Kg6 20. gxf6 fxe3 21. f7

(21. Nd5 Kf7 22. Rg5 e2 23. Re1 Nxf6)

21...Kg7 22. Nd5 e2 23. Re1 Nc5 24. Rf3 Rxa2 25. Rxe2 Ra1+ 26. Kg2 Be6 27. Ref2 Rf8

18...Ra5 19. Nfd5 Nxg4 20. h3 Nge5 21. Ne7 Kg7

In either case white's attack peters out.

  tamar: <Alekhine: ‘Incomprehensible! By simply taking the knight Black would have obtained at least a draw. For example: 18...gxf4 19 g5+ Kg7 20 gxf6+ Nxf6 21 Rg5+ Kf7 22 exf4 h6 23 Rg3 Nh5.’>

The Winter article linked above gives side by side notes.

Boboljubov won Moscow 1925, but his result would have been immeasurably more sensational had he won this game.

May-18-07  BadTemper: This game definitely deserves more kibitzing. Please refer to the above mentioned Winter article re 20 annotations of this game.
May-05-08  CharlesSullivan: To make a long story short, Kasparov (and everybody else) concludes that Capablanca missed a win at move sixteen (16.Qf7!), after which Bogoljubov had a winning game until missing 18...Ra5! Was Capa's 16th move so awful that he went from won to lost? Kasparov must think so, because he awarded White's 17th and 18th moves exclamation points! However, 17.Qxb6 is actually an error--the correct move to draw is 17.Qf7! Rf8! and now 18.Qe7! (which seems to have gone unnoticed) draws. Black's obvious attempt to win is 18...Qxe3+ 19.Kh1 gxf4 (if 19...Qf3+ then 20.Ng2 Qxg4 21.Ne3 and White now has the edge), but White plays 20.Rg1! and the threat of 21.g5+ is so horrific that Black, two pieces ahead, must take the draw: 20...Qf3+ 21.Rg2 Qf1+ 22.Rg1 Qf3+ and perpetual check! By the way, 18.Qe7 can now be found at the very end of the Edward Winter article at http://www.chesshistory.com/winter/...

  Calli: My favorite line is Capablanca's analysis of 26 Rh3+ Kg4 27 Kg2! Nxe4 28 Rd5 Nxc3


click for larger view

and now 29 Rh4!+ gxh4 30 Nh6!+ Rxh6 31 h3 mate Beautiful

Feb-20-09  jsteward: Why not 26.Rh3# Kg4 27.h3 mate!
Feb-22-09  jsteward: correction to 2/20 kibitz..h3 is not needed here! The move sequence is.....26.Rh3+ Kg4 27.Rg3++
Nov-28-11  Whitehat1963: Why not 10...Qb6?
Nov-28-11  Retireborn: <Whitehat> My notes give 10...Qb6 11.Nxc5 Nxc5 12.0-0 Qc6 13.Rc1 Ncxe4 14.Nxe4 Qxe4 15.Bc5! Qd5 16.Re1+ Kf7 17.Re7+ Kg6 18.Bd4 Be6 19.Rc5! (threat 20.Qd3+) Qe4 20.Re5 and White wins.

Fritz suggests that 18...Be6 in this line is a mistake, and offers 18...Rd8 19.Qd3+ Qf5 20.Qe3! when White has attacking chances and reasonable compensation for the piece.

So 10...Qb6 may well be a better move.

  Peligroso Patzer: Notes by Garry Kasparov available in the copy of this game in ChessBase's <MegaDatabase 2012> explain the competitive context of this game, as follows:

"Efim Bogoljubow, originally born in Russia, but later emigrated to Germany, was for more than a decade one of the top chess players in the world. Twice, in 1929 and 1934, he even challenged Alekhine for the world championship title, however without success. The tournament in Moscow in 1925 was the greatest triumph of his career. He won the event ahead of Lasker and Capablanca. A big contribution to his success was the fact that as the effective champion of Soviet Russia he knew the Soviet participants very well and scored +7, –0, =2 against them. Before this game Capablanca was two points behind the leader, which is why the world champion was prepared to take risks which under normal circumstances he would consider unacceptable." - Kasparov

  plang: Played in the 19th round; Bogoljubov finished at 15.5-4,5 a point and a half ahead of Lasker and two points ahead of Capablanca. Winter described this game as "one of the most complex games ever played" and wrote an article for British Chess Magazine including analysis and comments by such players as Lasker, Alekhine, Euwe, Spielman and Tartokower. Two rounds earlier against Zubarev Capablanca had played 5 d5 and had won a brilliancy but he considered 5 Bxc4 to be stronger. 7..Bc5 was new and has not been repeated though 7..a6 and 7..Nbd7 are not promising either. Bogoljubov gave 8..Nbd7?! provoking the bishop sacrifice an exclamation point though no one else agreed with him. 10..Qb6 was probably a tougher defense though after 11 Nxc5..Nxc5 12 Rc1 White has good attacking chances. Lakdawala recommended 11..Bb4 12 Bd4 keeping the f-file closed though White still would have promising attacking chances. Almost all of the analysts say that the exchange of queens was Capablanca's best option giving the alternative 17 Qf7..Rf8; Lakdawala disagreed continuing that line with 18 Qe7..Qxe3+ 19 Kg2..gxf 20 Rf1 with an unclear position. With 19..Nxg4? (19..Nxd5 was better) Bogoljubov may have underestimated White's attacking chances. Impossible was 32..Nge5 33 Rh6+! and mates next move. Bogoljubov blundered with 27..Kxg6?; a tougher defense was 27..hxg 28 e5 though White should still win.

A great fighting game.
