The Sveshnikov breaks a rule on purpose: Black plays 5...e5, kicking the knight but leaving a gaping hole on d5 and a backward pawn on d6. For decades that looked like bad chess; then Evgeny Sveshnikov proved the activity Black gets in return is worth it, and Magnus Carlsen made it his main defence in a world championship match. It is a concrete, self-confident opening where Black plays for the initiative from move five.
Kick the d4-knight with 5...e5, accept the d5 hole and backward d6-pawn, then generate piece activity with ...a6, ...b5 and the ...f5 break before White's positional bind settles.
White: Occupy d5: Ndb5 and Bg5 pressure f6 so a knight can sit on d5 permanently, often after Bxf6. Then blockade, restrain the ...f5 break, and slowly convert the better structure. Nd5 followed by c3 and a4 against Black's queenside pawns is the standard positional treatment.
Black: Chase the b5-knight with ...a6, expand with ...b5, develop the f8-bishop actively (often to e7 or via g7 after ...g6), castle, and prepare ...f5. Piece activity and kingside space must keep compensating for the d5 hole; passive play loses positionally.
It is a genuine weakness, and Black knows it. The argument is dynamic: the tempo gained by 5...e5, the queenside expansion with ...b5, and the ...f5 break add up to activity that outweighs one square. Carlsen trusted it in a world championship match, which settles the soundness question.
Yes, if you like active piece play and can accept structural ugliness. The plans are clear (...a6, ...b5, ...f5), and club opponents rarely know the precise theory needed to exploit d5. If you need tidy pawn structures to feel safe, pick another Sicilian.
The main line with 7.Bg5 and 9.Nd5 (or 9.Bxf6) aiming to own d5 forever is the critical test. Sidesteps like the Rossolimo move order (3.Bb5 against 2...Nc6) avoid the discussion entirely, which is exactly why many White players choose them.
