The Sicilian Defence: systems, plans and Anti-Sicilians

The Sicilian Defence is 1.e4 c5. In the Open Sicilian (2.Nf3 and 3.d4), Black trades the c-pawn for White's d-pawn and gets the half-open c-file.

White usually attacks on the kingside, Black on the queenside.

1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6

The Najdorf. 5...a6 controls b5 and keeps both ...e5 and ...e6 available.

The main Open Sicilian systems

  • Najdorf (5...a6): flexible, sharp and heavily analysed.
  • Dragon (5...g6): the bishop goes to g7. White often castles queenside and pushes h4-h5.
  • Classical (5...Nc6): natural development; 6.Bg5 is the Richter-Rauzer.
  • Accelerated Dragon (2...Nc6 and an early ...g6): White can answer with the Maroczy Bind, c4.

Anti-Sicilians to prepare first

Many club opponents avoid the Open Sicilian. Prepare for the Alapin (2.c3), the Closed (2.Nc3 and g3), the Grand Prix (2.Nc3 and f4), the Smith-Morra Gambit (2.d4 cxd4 3.c3) and the Rossolimo (2.Nf3 Nc6 3.Bb5).

Plans that repeat

  • Black's rooks belong on the c-file, and ...Rxc3 is a standard exchange sacrifice.
  • After ...e5, d5 becomes a weak square, and White wants a piece on it.
  • With castling on opposite sides, count moves. The slower attack usually loses.

Key takeaways

  • Prepare Anti-Sicilians before deep main-line theory.

Frequently asked questions

Is the Sicilian too hard for club players?
Not if you choose a system with repeating plans, such as the Kan (2.Nf3 e6 3.d4 cxd4 4.Nxd4 a6) or the Accelerated Dragon. Both need less memorisation than the Najdorf.
