Sicilian Defence — Sveshnikov
B33 · Played as black · Advanced · Sicilian
A permanent hole on d5 traded for two bishops and raw activity
The main line
1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 e5 6.Ndb5 d6 7.Bg5 a6 8.Na3 b5 9.Bxf6 gxf6
Strategic ideas
- Accept the backward d-pawn and the d5 hole in exchange for concrete piece play
- Kick the b5-knight to the rim with …a6 so it plays no part in the game
- Gain the bishop pair and the half-open g-file after …gxf6
- Expand on the queenside with …b5–b4 to drive the knight off c3 and claim d5 yourself
- Push …f5 to open lines and give the doubled f-pawns a purpose
Key themes
- Dynamic — Black voluntarily wrecks the structure — every move afterwards must justify it with activity
- Counterattack — The …b5–b4 and …f5 advances turn a static weakness into a wave of counterplay
- Piece Activity — The bishop pair, the open g-file and pressure on c3 are the compensation for the d5 hole
Typical plans
Black plays …e5 in the Open Sicilian, hitting the d4 knight but leaving a permanent hole on d5 and a backward pawn on d6. This looks like a structural crime and is in fact one of the most respected defences in chess. Black chases the knight to a3 with …a6, takes the bishop pair after …gxf6, and then expands with …b5–b4 and …f5. White's whole game revolves around occupying d5; Black's revolves around proving that pieces beat holes.
Move by move
- e4 — White claims the centre and opens lines for rapid development.
- c5 — Black answers asymmetrically, fighting for the centre without mirroring White.
- Nf3 — White develops and prepares to challenge c5 with d4.
- Nc6 — Black develops the knight, eyeing d4 and preparing …e5.
- d4 — White opens the centre, offering the trade that defines the Open Sicilian.
- cxd4 — Black captures toward the centre, gaining a tempo on White's f3-knight.
- Nxd4 — White recaptures centrally with the knight.
- Nf6 — Black develops and hits e4, provoking White into defending it.
- Nc3 — White defends e4 and completes queenside development.
- e5 — Black plays the defining move, kicking the knight and grabbing central space — at the cost of a permanent hole on d5.
- Ndb5 — White jumps to b5, immediately eyeing the hole on d6 that …e5 created.
- d6 — Black plugs the hole with the pawn, accepting that d6 will be backward for the rest of the game.
- Bg5 — White pins the f6-knight, preparing to trade it off and deepen the grip on d5.
- a6 — Black kicks the knight at once — it has nowhere good to go.
- Na3 — White retreats to the rim, where the knight sits out of play until it can reroute via c2 or c4.
- b5 — Black gains queenside space and prepares …b4 to drive the c3-knight away from d5.
- Bxf6 — White trades on f6, wrecking Black's kingside structure to make d5 permanently weak.
- gxf6 — Black recaptures with the g-pawn — not the f-pawn — keeping the centre intact, opening the g-file and preparing …f5. The doubled pawns are the price of the bishop pair.
