ECHECS PARTIE N o138
Sicilian, Scheveningen (Paulsen), classical variation, with 7.0-0 Be7 8.a4 Nc6, Maroczy System (8.a4) [B85]. 1.e4
The famous Sicilian Najdorf [B90]. Hence, the Scheveningen may be considered as a refinment of the Najdorf. 6.Be2
...e6 and ...a6 may be played in an order or in the opposite. 7.0-0
The Maroczy System is usually played in the following move order: 7...Qc7
Since 1928 the main line continues by: 8.f4
as in the game: 11...Re8
Radjabov, Teimour (2682) - Babula, Vlastimil (2604) (39 m.) 1-0 [B85] EU-cup 21st Saint Vincent 23.09.2005.] 8...Nc6
In an other move order we reach the main line. 11...Re8
This time the position is the same than in Radjabov - Babula 1-0 [B85] 2005. 12.Bf3
The novelty that Magnus Carlsen has found for this game.
In this position Michael Adams versus Anand chose to pursue by: 15.Nde2
The standard reply. 15...exf4
+/= Adams, Michael (2741) - Anand, Viswanathan (2786) (28 m.) 1/2-1/2 [B85] Linares 22nd 02.03.2005.] 15...dxe5
Of course, an alternative choice is to take back the pawn by the Knight: 15...Nxe5!?
but, at the analysis, this reply may be risked: 16.Bg5
Not the weak answer: 16.Be2?!
which may be followed by by the play line: 16...Neg4
= In this rather open position, Black owning a pair of Bishops against two Knight, does not have any problem. ) 16...Nfg4
Presumably the best move. (
Is not so good: 17.Bxg4?!
+/= and Black has practically equalized. ) 17...Nxf3!?
And then Black has only one way for continuing: 21...Bxd5
White has a significant advantage but the game is not clear.] 16.Nb3
is obviously a good alternative. The two Bishops control adjacent open diagonals a3-f8 and a2-g8. Is then playable: 17.Rad1
and then for example: 18.Bb6
Is usual in such a position, before to play the Bishop in b6. The Rook is forced to go back in a8. 17...Ra8
In all this phase White has the initiative, but Black finds a relatively accure defense, preserving his chances to equalize.
It is not advised to play: 18...Qc6?!
It is frankly a bad idea to take the c2-pawn: 20...Nxc2??
and White has a winning game! ) 21.Rd2!
+/= with a significant White initiative.] 19.Rad1
An inaccurate move allowing White to pursue develop his progression on the Queen side with threat.
Black has the opportunity of an active defense: 19...Bg4
+/= White has a little advantage due to the control of the d-file.] 20.Nd5!
With the idea to create a dangerous passed pawn on the d-file.
Is not so sharp than the Magnus' choice: 20.Nc5
White of course has a clear advantage but Black may choose to continue by 22...Bxd5 or 22... Qd6.] 20...Bxd5
The only correct reply.
loses a pawn: 21.exd5
Is a blunder: 20...Nfxd5??
+ - and White wins.] 21.exd5
The subjacent idea is to play the Queen en f5 in view to exchange the Queens. But the resulting endgame will be favourable to White.
The only accurate defense is: 22...Qe5
Forcing more or less the Queen exchange. Among other alternatives, it may follow: 27.Rxb7
+/= White has only a small advantage and the game is not clear. ) 26.Rxb7
and then possibly 28.c4
with only a little White advantage.] 23.Nc5!
The best choice indeed. 26.a5
Seems correct but this move is not the best opportunity for White.
Rather strong is: 26.Rxf6!
+/- and then Black is practically in zugzwang. ( 28.b4
forcing the advance of the d-pawn. 29.d7
In view ta take back the control of the d8-square. 30.axb6
and White has a winning advantage. ) ] 26...Nxb6
A serious mistake.
Black did not have a better possibility than: 27...Rec8!
The ending is unclear and Black has some chances to draw.] 28.Rxf6!
Taking the full control of the d7-square. 28...gxf6
The only winning move. 29...f5
A strong answer among other alternatives. Black can undertake nothing. 30...a5
A superb rip off! 33...Bf6
The Bishop is untouchable since: 33...bxa6??
A beautiful Carlsen' s game in spite of some inaccurate replies of his opponent. 1-0
