The Najdorf Sicilian: 1.e4 c5 2.Nf3... 6.Bg5 begins with 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.Bg5 (ECO B94). White pins the f6-knight and threatens to ruin Black's structure if the bishop is allowed to capture. Black has essentially one move that doesn't fall apart.
Strategic Overview
6.Bg5 is the sharpest, most theoretical, and most aggressive answer to the Najdorf. White pins the f6-knight against the d8-queen, and the threat of Bxf6 followed by doubled pawns on the f-file is real and immediate. Black's response is essentially forced: 6...e6, the standard developing move that breaks the pin once the bishop swings to e7 or Nbd7 supports the knight. The lines that follow are some of the deepest, most analyzed positions in chess — the 7.f4 main line branches into the Poisoned Pawn Variation with 7...Qb6 (where Black snatches the b2-pawn under threat and dares White to prove compensation), the Polugaevsky with 7...b5, the Browne Variation with 7...Be7, and several others. The whole 6.Bg5 complex is the battlefield where world championship matches have been won and lost. Strategically, White accepts an early commitment of the dark-squared bishop in exchange for maximum tactical pressure on Black's position; Black accepts that the position is sharp and concrete in exchange for chances to grab material or generate counterplay along the queenside. There's no middle ground here — Black either knows the theory cold or gets crushed, and the same applies to White. It's the line for players who love sharp Sicilian theory.
Key Ideas
The recurring motifs below distinguish a confident handler of this opening from a beginner:
- The pin is the whole point — Bg5 pins the f6-knight and threatens Bxf6 with doubled f-pawns for Black. The threat shapes everything that follows — Black has to address it immediately or accept a permanent structural concession.
- 6...e6 is essentially forced — Almost any other move leaves Black with a damaged structure or worse problems. The e6 push prepares ...Be7 to break the pin and is the foundation of all the main theoretical lines that follow.
- Maximum theoretical depth — The 6.Bg5 complex contains some of the deepest preparation in chess — Poisoned Pawn, Polugaevsky, Najdorf Main Line, Browne. World championship matches have been decided here. Both sides need serious preparation.
- Sharp from move six — There's no slow maneuvering in this line. White is committed to attacking, Black is committed to counterpunching, and the games tend to be wildly tactical and decisive. It's the antithesis of a quiet positional Sicilian.

Move Diversity and Theory Depth
Looking at move selection shows how forcing — or not — the position really is. At 1200 Elo, the top reply is e6, played 45.2% of the time. There are 3 other moves seeing meaningful share, and 84.2% of games stick to established theory. Entropy: 2.15. By 2500, e6 dominates at 67.9% of replies; only 2 viable alternatives remain and 98.4% of moves are theory. Entropy drops to 1.11. That entropy collapse is the signature of a line where preparation pays off: at the top, players know the best move and play it.

Each branch leads to a different middlegame character — the resulting pawn structure decides what kind of game you get.
Common Mistakes
- Drifting away from main theory — At 400 Elo, theory adherence sits at 76.5% — versus 95.4% at 2000. The most popular deviation is e5 (played 34.5% of the time at 400, much less so up top). It looks fine but quietly hands the better-prepared side an edge.
- Neglecting development — It can feel productive to make extra pawn moves early, but falling behind in piece development is what loses most amateur games — especially in open positions where active pieces find squares fast.
- Ignoring the kingside attack — In sharp Sicilian lines, White typically castles long and pushes the h-pawn. Without your own counterplay on the queenside or in the centre, White's attack lands first.
