  1. Before the first move

    The Najdorf Variation is one of Black's most ambitious weapons against the Open Sicilian. By playing a6, you control the b5-square and prepare for queen-side expansion. White's 6.g3 choice, the Zagreb Variation, aims for a solid, positional setup where the bishop fianchettos to g2 to control the long diagonal.

  2. 1. e4White

    White begins with e4, the king's pawn opening. This is the most popular first move, inviting immediate central tension. You have many ways to respond, but the Sicilian Defense with c5 is the most combative choice against this setup.

  3. 1... c5Black · your move

    Move your pawn to c5 to enter the Sicilian Defense. By attacking the d4-square from the flank, you create an asymmetrical position where you can fight for the center without immediately mirroring White's moves.

    Other paths here: f6 (Barnes Defense) · g5 (Borg Defense) · h6 (Carr Defense) · f5 (Duras Gambit)

  4. 2. Nf3White

    White plays Nf3, the most common continuation. While White could try the Bowdler Attack with Bc4 or the Keres Variation with Ne2, this knight move is the most principled way to prepare for a central breakthrough.

    Other paths here: Qg4 (Sicilian Defense: Amazon Attack) · Bc4 (Sicilian Defense: Bowdler Attack) · Nh3 (Sicilian Defense: Brick Variation) · g4 (Sicilian Defense: Grob Variation)

  5. 2... d6Black · your move

    Push your pawn to d6. This move controls e5 and prepares to develop your light-squared bishop. It is a fundamental building block of the Najdorf and Dragon structures, keeping the center flexible.

    Other paths here: f5 (Sicilian Defense: Brussels Gambit) · h6 (Sicilian Defense: Bücker Variation) · g6 (Sicilian Defense: Hyperaccelerated Dragon) · e5 (Sicilian Defense: Jalalabad Variation)

  6. 3. d4White

    White plays d4, the defining move of the Open Sicilian. White could also choose the Delayed Alapin with c3 or the Kopec System with Bd3, but d4 is the most aggressive way to fight for an advantage.

    Other paths here: c3 (Sicilian Defense: Delayed Alapin Variation, with d6) · Bd3 (Sicilian Defense: Kopec System) · b4 (Sicilian Defense: Wing Gambit, Deferred Variation) · b3 (Sicilian: 2.Nf3 d6 3.b3)

  7. 3... cxd4Black · your move

    Capture the pawn on d4 with your c-pawn. This trade opens the c-file for your rook and removes White's central pawn, creating the characteristic imbalance that makes the Sicilian so dangerous for both sides.

    Other paths here: Nf6 (Sicilian Defense: Modern Variations, Anti-Qxd4 Move Order) · Nd7 (Lazy Knight Variation, Sicilian)

  8. 4. Nxd4White

    White recaptures with Nxd4, placing a strong piece in the heart of the board. The alternative, recapturing with the queen, leads to the Chekhover Variation where Black can often gain time by attacking the exposed queen.

    Other paths here: c3 (Sicilian Defense: Modern Variations, Tartakower) · Qxd4 (Sicilian Defense: Chekhover Variation)

  9. 4... Nf6Black · your move

    Develop your knight to f6, attacking the e4 pawn. This forced move develops a piece and compels White to defend the center, usually by bringing out the other knight to c3.

    Other paths here: g6 (Sicilian Defense: Dragon Variation, Accelerated Dragon) · a6 (Sicilian: Open, 2...d6, 4...a6) · e5 (Sicilian: Open, 2...d6, 4...e5)

  10. 5. Nc3White

    White defends with Nc3. Alternatives like the Prins Variation with f3 or the more passive Bd3 exist, but this is the main line of the Sicilian, preparing for the most critical variations to come.

    Other paths here: Bc4 (Sicilian Defense: Modern Variations, Ginsberg Gambit) · f3 (Sicilian Defense: Prins Variation) · Bd3 (Sicilian: Open, 2...d6, 4...Nf6 5.Bd3)

  11. 5... a6Black · your move

    Move your pawn to a6 to enter the Najdorf. This subtle move prevents White's pieces from landing on b5 and prepares your own expansion with b5, giving you great flexibility in the center.

    Other paths here: Nc6 (Sicilian Defense: Classical Variation) · Bd7 (Sicilian Defense: Kupreichik Variation) · e5 (Sicilian: Open, 2...d6, 5.Nc3 e5) · Nbd7 (Sicilian: Open, 2...d6, 5.Nc3 Nbd7)

  12. 6. g3White

    White plays g3, opting for a fianchetto system. Instead of the aggressive English Attack with Be3 or the Adams Attack with h3, White chooses a solid setup to control the long diagonal and play for long-term pressure.

    Other paths here: h3 (Sicilian Defense: Najdorf Variation, Adams Attack) · g4 (Sicilian Defense: Najdorf Variation, Dekker Gambit) · Be3 (Sicilian Defense: Najdorf Variation, English Attack) · Rg1 (Sicilian Defense: Najdorf Variation, Freak Attack)

  13. Where you stand

    The Zagreb Variation leads to a more strategic battle than many other Najdorf lines. White will fianchetto the bishop to g2 and castle kingside, while Black typically counters with e5 or e6, aiming for a central break. Both sides must balance king safety with the fight for the d5-square, which often becomes the focal point of the middlegame.

    • f1-g2 Fianchetto the bishop to control the long diagonal
    • e1-g1 Castle kingside to secure the king
    • e7-e5 Challenge the center and gain space
    • b8-d7 Develop the knight to support the center
    • c8-e6 Develop the bishop to an active square
