Sicilian Defense: Sveshnikov Variation
Initial Moves: 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 e5
Strategic Summary & Main Idea
The Sveshnikov Sicilian answers the open centre with 5...e5, driving the d4 knight away and accepting a permanently weak d5 square in exchange for time and activity. It is the lowest-measuring open Sicilian for White: +0.25 after 5...e5, below the Najdorf and the Classical in the Sicilian entry. What the measurement shows is how much the main line costs White. With 9.Bxf6 gxf6 and Black's doubled pawns, the position reaches 0.00 after 13...Ne7; the alternatives that avoid the exchange, 7.Nd5 and 9.Nd5, keep +0.39 and +0.34.
The pawn structure this opening produces
The Sveshnikov accepts the Sicilian's most committal structure. After 5...e5, the d6 pawn is backward on a half-open file and the d5 square has no Black pawn that can control it. That is exactly the square White wants to occupy with a knight, which is why the main line goes through Na3-c2-e3 and through Bg5xf6, which removes d5's defender. Black answers with ...a6 and ...b5, which drive the White knight to a3, where it stands badly. After 9.Bxf6 gxf6, Black's structure changes shape: the doubled f-pawns look weak, but they control e5 and g5, and the ...f5 push opens the g-file and challenges e4. Black gains the bishop pair and a mobile centre, White gains d5 and the d6 target. When White does not take on f6, with 9.Nd5, the structure stays intact and the play is manoeuvring around d5.
Typical Plans for White
- Occupy d5 with a knight after trading the f6 knight with Bxf6
- Avoid the exchange on f6 with 7.Nd5 or 9.Nd5 and keep the edge: +0.39 and +0.34
- Against ...f5, play Bd3 and castle and blockade the kingside with c3 and Nc2
- Reroute the a3 knight via c2 and e3 to d5
- Do not retreat 6.Nb3 against 5...e5: the knight leaves play and the position measures −0.23
Typical Plans for Black
- Drive the b5 knight away with ...a6 and ...b5 and leave it on a3
- After Bxf6 gxf6, push ...f5 and use the bishop pair against White's centre
- Trade the c8 bishop for the d5 knight when it arrives on the square
- Do not play 6...h6 against 6.Ndb5: 7.Nd6+ trades the good bishop and measures +0.83
- Do not develop with 8...Be6 before ...b5: 9.Nc4 eyes b6 and d6, +0.51

Frequently asked questions
Is the Sveshnikov the best Sicilian for Black?
By the evaluation, it gives White the least: +0.25 after 5...e5, against +0.32 for the Najdorf and +0.40 for the Classical in the Sicilian entry. The gap to the Najdorf is seven hundredths, so the choice is about structure: the Sveshnikov accepts a weak d5 square in exchange for immediate activity.
Why are the doubled f-pawns not a weakness?
Because they control e5 and g5 and prepare ...f5, which opens the g-file for the rooks and challenges e4. After 9.Bxf6 gxf6 10.Nd5 f5, the main line reaches 0.00. White gains d5 for the knight, but loses the bishop that could defend the dark squares.
How can White avoid the main line's equality?
By avoiding the exchange on f6. 7.Nd5 Nxd5 8.exd5 Ne7 measures +0.39, and 9.Nd5 Be7 10.Bxf6 Bxf6 11.c3 O-O 12.Nc2 Bg5 measures +0.34. Both keep Black's structure intact and leave White with d5 without giving up the bishop pair.

Common Mistakes & Where Most Amateurs Go Wrong
- 01 Playing 6...h6? against 6.Ndb5. The knight lands on d6 with check: 7.Nd6+ Bxd6 8.Qxd6 trades Black's dark-squared bishop, which guards d6 and e5, and the position goes from +0.25 to +0.83. The line:
