1. d4 {1)Alekhine:Hastings 1922.p.59. Vor der letzten Runde lagen Aljechin und
Rubinstein gemeinsam mit 6,5/9 an der Spitze. Rubinstein hatte noch mit Weiß
gegen Sir Thomas und Aljechin mit Schwarz gegen Bogoljubow zu spielen. Nachdem
Aljechin glänzend gewonnen hatte, mühte sich Rubinstein 114 Züge lang
punktgleich Turniersieger zu werden - vergebens.} Nf6 2. c4 g6 3. Nc3 Bg7 4. g3
{A: This is Rubinsteins favourite development played in all similar openings.
In the present game he was not, as it turned out, to obtain any marked
advantage.} d6 5. Bg2 O-O 6. e4 (6. Nf3 {main line} Nbd7 (6... Nc6 7. d5) 7.

simple and effective development from an irregular start makes one doubt,

position. White takes advantage of this mistake in masterly fashion.} ({
The natural move was} 9... Nd4 $142 $1 {forcing the exchange of minor pieces
with satisfactory game.}) 10. f3 {A master stroke, by which White prepares for
the advance on the Queens side. The Bishop, when on e3, must not be subject to
the threat of exchange by Ng4.} Nbd7 11. Be3 h6 12. b4 {[%mdl 36] From here up
to the won position on move 35 White plays correctly. The game affords a
typical example of a Queens side attack in a blocked position.} b6 13. Na4 a5
$2 {The opening of the a-file, as it will be seen, is entirely to Whites
advantage, but the threatened 14.c5 was very disagreeable.} 14. a3 axb4 $6 15.
axb4 Bb7 16. Nec3 Qe7 {Just in time! Had he delayed this move now, he could
never have freed the Queen.} 17. Nb5 Rec8 18. Bh3 Ne8 19. Qd2 Kh7 20. Nac3 {
The prime object of Whites play is to get posession of the open file, by
doubling the Rooks after Na7.} Rcb8 ({Black cannot counter by exchanging Rooks

no satisfactory move. The game is strategically lost.} 23. Rfa1 Bf8 24. b5 {
This is the initial move of a decisive manoeuvre. After the exchange at c6 and
of a Rook White will be able to attack the weak Pawn c7 in superior force.
This should have been the end.} Ng7 25. Nc6 Bxc6 26. bxc6 Qd8 27. Nb5 Ne8 28.
Qa2 Rxa3 29. Qxa3 h5 {Black at last makes an attempt to exchange one of his
inactive pieces, but it is much too late.} 30. Qa7 Bh6 31. Bxh6 Kxh6 32. Bd7 (
32. Qb7 {would be premature in view of} f5) 32... Ngf6 33. Kf2 {White
threatens 34.h3 followed by 35.g4 hg4 36.hg4, leading to the shifting of the
Nf6, after which Qb7 and Ra7 win off-hand.} g5 {Conscious of the danger Black
makes a move of despair.} ({The Bishop cannot be taken on account of} 33...
Nxd7 34. cxd7 Nf6 35. Qxc7 Qxc7 36. Nxc7 Nxd7 37. Nb5 {with a won end-game.})

was immediately decisive.}) 34... Kg7 35. Bf5 Kf8 {[%mdl 64]} 36. h4 $4 {
This move is very weak, as it gives Black for no reason at all somthing to
play for on the Kings side, after which the game can only be won with great
difficulty, or perhaps not at all.} ({As Rubinstein himself demonstrated, he
could have finished the game, played in a masterly fashion to this point, by

temporarily, as evidently White quickly recovers it with the Queen. Whites
winning chance now consists in the fact, that in most lines of play he can
invite exchange of Queens with a won end-game. Black has a very difficult game
to play and his method of conducting it merits only praise.} Qf6 44. Qe3 Ng7

Nachdem Rubinstein den sofortigen Gewinn verpaЯt hat (34.Bf5 und 36.Qb7)
laviert er vom 38. bis 95.Zug . Schwarz verteidigt sich aber sorgfдltig. Bei
seinem miЯglьcktem Gewinnversuch im 95. und 96.Zug gerдt WeiЯ in eine
Verluststellung, die Schwarz aber nicht ausnutzt (100...Qf2?). Die SchluЯphase
spielt WeiЯ wieder erfindungsreich und stark und sichert sich so das Remis.}
