The Najdorf isn’t one line — it’s a whole tournament of them, all branching from White’s sixth move. Below are the major named variations, each with its moves, its core idea, and who it tends to favor. Think of this as the map you pull out before deciding how you want your Najdorf games to feel. Everything here grows from the same tabiya (1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6) — for the shared move order, see the moves page.
The 30-second version
- White’s sixth move names the variation: 6.Be3 (English Attack), 6.Bg5 (Main Line / Poisoned Pawn), 6.Bc4 (Fischer–Sozin), 6.Be2 (Classical), 6.f3 and 6.h3 (modern).
- Sharper = more theory, bigger risk/reward. Calmer = lower maintenance.
- Every one of these is engine-verified as roughly balanced — the Najdorf holds up everywhere.

English Attack (6.Be3)
Moves: 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.Be3
The modern main road, and the reason the Najdorf feels so dangerous today. White sets up f3, Qd2, g4, and 0-0-0, then rolls the kingside pawns at Black’s king. Black usually answers 6…e5 (space, our diagram below) or 6…e6, then races on the queenside with …b5 and …b4.
Who it favors: brave players on both sides. It’s a genuine opposite-wing race where the smallest tempo matters. If you love calculating attacks, this is home.
6.Bg5 — the Classical Main Line
Moves: 6.Bg5 e6 7.f4 Be7 8.Qf3 Qc7 9.O-O-O Nbd7
For decades the main line of the Najdorf. White pins the f6-knight, plays f4, and castles queenside with pressure on the center and e-file. Black develops solidly with …Be7, …Qc7, and …Nbd7, aiming for …b5 counterplay. It’s deeply theoretical but structurally sound for both sides.
The Poisoned Pawn (6.Bg5 e6 7.f4 Qb6)
Moves: 6.Bg5 e6 7.f4 Qb6 8.Qd2 Qxb2 9.Rb1 Qa3
The most notorious gambit in the whole Sicilian. Instead of developing, Black sends the queen to b6 and snatches the b2-pawn — right in the corner, deep in enemy territory. It looks suicidal. It isn’t. White gets a lead in development and attacking chances; Black gets a pawn and a rock-solid position if defended precisely. Fischer used it; so did Kasparov.
We engine-checked the tabiya: it’s roughly equal — sharp, double-edged, and a memory test, but sound. Just note that 9…Qa3 is close to forced; a careless queen retreat can be punished. We break the pitfalls down on the traps page.
Fischer–Sozin Attack (6.Bc4)
Moves: 6.Bc4 e6 7.Bb3 b5
Bobby Fischer’s pet weapon against the Najdorf (yes, he played both sides of this opening at the highest level). White develops the bishop to c4, then retreats it to b3, aiming the whole battery at Black’s f7 and e6 weak spots. Black counters with rapid queenside expansion (…b5, …Bb7) and must watch for sacrifices on e6.
Who it favors: attackers with White who enjoy sacrificing on e6, and Black players who don’t panic and know the defensive resources.
Classical / Opočenský (6.Be2)
Moves: 6.Be2 e5 7.Nb3 Be7 8.O-O O-O 9.Be3
The grown-up, low-drama Najdorf. White simply develops the bishop to e2, castles kingside, and plays for a slow positional squeeze — the main target is the d5-square. No pawn storms, no gambits, just maneuvering. It’s a great choice for White players who want a Najdorf without memorizing 25 moves of theory, and it still poses real problems.
Modern move orders: 6.f3 and 6.h3
Two fashionable finesses that both aim for English-Attack setups while dodging specific Black tricks:
- 6.f3: heads for f3/Be3/Qd2/g4 but sidesteps the annoying …Ng4 jump (there’s no bishop on e3 to hit yet). Black usually replies 6…e5.
- 6.h3: the Adams Attack — a quiet little move preparing g4 with no downside. It’s the very line Bobby Fischer used to crush Miguel Najdorf at the 1962 Varna Olympiad, and it’s had a big modern revival. Black often answers 6…e5.
Both were engine-verified as roughly balanced — modern, low-theory ways for White to reach familiar attacking structures.
How the variations actually differ (in one breath)
It’s easy to drown in sixth-move names, so here’s the mental model. Every Najdorf shares the same DNA — …a6, the flexible center, …b5 counterplay, the fight over d5. What changes from variation to variation is how aggressively White goes for Black’s king:
- 6.Be3 / 6.f3 / 6.h3 = build the g4-h4 pawn storm and castle queenside (maximum aggression).
- 6.Bg5 = pin, f4, and central pressure with 0-0-0 (sharp but more piece-based).
- 6.Bc4 = aim the bishops at f7/e6 and sacrifice (targeted attack).
- 6.Be2 = castle short and squeeze the d5-square (patience).
Once you see it that way, choosing your response as Black comes down to one question: how much theory are you willing to learn, and how much do you enjoy defending a storm?
Najdorf vs. Dragon
If you’re weighing the Najdorf against its sharper sibling, we compare them directly in Najdorf vs Dragon. The Najdorf hides its plans and maneuvers; the Dragon commits to a fianchetto and an all-out race.
Which Najdorf setup should you meet, and how?
- Facing 6.Be3 or 6.f3/6.h3? Choose …e5 or …e6 and race on the queenside — know your …b5/…b4 timing.
- Facing 6.Bg5? Go solid with …e6/…Be7/…Qc7, or gamble with the Poisoned Pawn if you’ve studied it.
- Facing 6.Bc4? Expand with …b5, develop calmly, and guard e6.
- Facing 6.Be2? Relax into a maneuvering game and fight for d5.

FAQ
What’s the best variation against the Najdorf? There’s no single best. The English Attack (6.Be3) is the most fashionable and testing; 6.Bg5 is the deepest theoretically; 6.Be2 is the most practical low-theory choice. All are sound.
What is the Poisoned Pawn Variation? It’s 6.Bg5 e6 7.f4 Qb6, where Black grabs the b2-pawn with the queen. It’s a sharp, sound gambit — Black gets a pawn, White gets development and attacking chances. Deeply theoretical.
Is the Fischer–Sozin dangerous? Yes — the Bc4/Bb3 battery generates real threats against f7 and e6, including sacrifices. But with accurate defense Black is fine, which is exactly what the engine says.
