The Sveshnikov Sicilian

Introduction

This opening paper focuses on the main 10 Bxf6 Bxf6. It places a bias on the systems which involve black playing an eventual g6 followed by f5. It tries to determine the appropriate timing for the implementation of this plan.

Starting Position

This variation of the Sicilian starts with the diagram in the following position which can be reached by the following move order:

1 e4 c5 2 Nf3 Nc6 3 d4 cxd4 4 Nxd4 Nf6 5 Nc3 e5

Black commits himself to a weakness on d5. Play can revolve completely around this weakness now.

This white paper shall focus on the variation after:

Ndb5 d6 Bg5 a6 Na3 b5.  The main line from the above position runs:

Nd5 Be7 Bxf6. This reaches the following "starting position":

White’s usual plan based on the d5 square, is try and get knight on a3 to the central square e3 via the manoever c3 Nac2-e3. c3 is a logical move therefore to start this plan off. Black then has to find an effective plan. Let us examine two key systems for black. The first system is 11 c3 0-0 12 Nc2 Bg5. White now has the move a4, which can lead to bxa4 Rxa4 as shown in the following position:

 

The question is now, what are blacks effective plans?

Black has an isolated pawn on the a file, and a weak d5 square. Black needs to generate sufficient counterplay to balance out these weaknesses. An example of  play which leads to the main "starting position" of this whole line is: a5 Bc4 15..Rb8 16 b3 Kh8 17 0-0 f5 18 exf5 Bxf5 Nce3 Be6

 

Now according to Mikhail Krasenkov in his book on the Sicilian sveshnikov, this is okay for black because black has a pair of bishops and counterplay against the white b3 and f2 pawns which compensate for the weakness of the a5 and d6 pawns and the d5 square..

I do not personally like this position for black compared with the variations which involve black playing g6 followed by f5. This is my kings indian bias. In the kings Indian, you would not normally allow an exf4 because white would gain the e4 square for a knight.

In my games in practice, with the g6 f5 plan, sometimes the g file can be used with effect.

Krasenkov does mention 17..g6 as the main alternative to f5. The line he gives where Black maintains sufficient counterplay is 18 Qe2 Bd7 Rfa1 Bh6 g3?! (20 b4) f5 exf5 gxf5 b4 e4! (Lutz-Kramnik, Germany 1995) - see example game below

Has the timing of g6 followed by f5 been improved, by not using the system with 12 ... Bg5, and instead going for an immediate g6, and in an analogous way to the kings indian, putting the bishop to g7 ?;

Conclusions

Given that g6 and f5 is an effective plan, the author questions, whether 12 .. Bg5 is as good as the immediate g6 followed by Bg7 and f5.
