So you want to actually play the Najdorf, not just admire it. Let’s walk the main line one move at a time, so you understand the why behind each move instead of memorizing letters. We’ll follow the most instructive modern highway: the Najdorf running into the English Attack, where both sides castle opposite and prepare to race.
The 30-second version
- Main line: 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6.
- The key choice: after …a6, Black eventually plays either …e5 (space) or …e6 (compact). The whole opening flows from that decision.
- The branch point: White’s sixth move (6.Be3, 6.Bg5, 6.Bc4, 6.Be2, 6.f3, 6.h3) names the battle.

The Najdorf into the English Attack — the most important modern main line, move by move.
Move by move
1.e4 c5 2.Nf3 d6
White grabs the center; Black answers with the Sicilian’s flank pawn and then plays 2…d6, supporting a future …e5 and opening a diagonal for the c8-bishop. This is the Najdorf/Scheveningen move order — Black commits to a …d6 structure early.
3.d4 cxd4 4.Nxd4 Nf6 5.Nc3
The heartbeat of the Open Sicilian: White strikes with 3.d4, Black trades 3…cxd4, White recaptures 4.Nxd4. Then 4…Nf6 hits e4 with tempo, and 5.Nc3 defends it while developing. If any of this is unfamiliar, the Sicilian Defense moves page covers this shared opening in detail. We’re now at the Open Sicilian crossroads — and Black is about to make it a Najdorf.
5…a6 — the Najdorf move
Here it is. 5…a6. It looks like nothing and means everything:
- It takes away the b5-square — no White knight or bishop can leap to b5 to pester d6 or c7.
- It prepares …e5 or …e6 — Black keeps the center flexible and will choose later.
- It supports …b5, the queenside pawn break that drives Black’s counterplay.
6.Be3 — the English Attack
Of White’s six main tries, we’ll follow the modern favorite: 6.Be3, the English Attack. White plans f3, Qd2, g4, and queenside castling — a kingside pawn storm. (For the other five sixth moves, jump to the variations page.)
6…e5 — Black claims the center
Now Black makes the big call: 6…e5, kicking the d4-knight and grabbing central space. The trade-off is real — this creates a hole on d5 that White will fight to occupy. But in return Black gets a mobile center and active pieces. (The other main choice here is 6…e6, keeping a compact “small center.”)
7.Nb3 Be6 8.f3
White retreats 7.Nb3 (the knight had no good square on the e-file). Black develops 7…Be6, guarding the critical d5-square. White plays 8.f3, bracing the e4-pawn and clearing the way for g4.
8…Be7 9.Qd2 O-O 10.O-O-O
Both sides complete the setup. 8…Be7 and 9…O-O tuck Black’s king away; 9.Qd2 connects White’s rooks and eyes the kingside; 10.O-O-O sends White’s king to safety on the queenside so the kingside pawns can fly.
Now it’s a full-blooded opposite-wing race. White plays g4, g5, h4, h5 at Black’s king. Black plays …b5, …Nbd7, …b4, …Rc8 at White’s. This is the Najdorf’s beating heart.
The …e5 vs …e6 decision (the most important idea)
If you remember one strategic thing about the Najdorf, make it this. After …a6, Black usually chooses between two center pawns:
- …e5 (as in our main line): grabs space and frees Black’s pieces, but concedes the d5-square and leaves the d6-pawn slightly backward. The fight becomes: can White exploit d5 before Black’s counterplay arrives?
- …e6: keeps a compact, flexible “small center” (pawns on d6 and e6), morphing toward Scheveningen structures. Solid and maneuvering, with a later …d5 or …b5 break in mind.
The genius of …a6 is that it lets Black delay this choice and pick the structure that best answers White’s setup. Against 6.Be3 and 6.Be2, …e5 is popular; against 6.Bg5 and 6.f4, …e6 is the norm.
Putting the queenside to work
The Najdorf’s counterplay engine is the …b5 break. A typical sequence is …b5, …Bb7 (or …Be6), …Nbd7, …Rc8, and then …b4 hitting the c3-knight. When that knight is forced to a worse square (a4, e2, or b1), two good things happen for Black:
- The e4-pawn can come under fire (a knight that abandons c3 stops defending e4).
- Lines open on the queenside, exactly where White’s king often lives in the sharp systems.
So when you reach a Najdorf middlegame and wonder “what’s my plan?”, the answer is usually: expand with …b5, castle, and make White’s queenside uncomfortable — while staying alert to the kingside storm.
Where it branches
The Najdorf’s whole personality is set on move six. Here’s your map (deep dives on the variations page):
| White’s 6th move | System | Vibe |
|---|---|---|
| 6.Be3 | English Attack | Sharp, opposite-side castling race |
| 6.Bg5 | Classical Main Line / Poisoned Pawn | Razor-sharp theory |
| 6.Bc4 | Fischer–Sozin | Attack on f7/e6 |
| 6.Be2 | Classical (Opočenský) | Calm, positional squeeze |
| 6.f3 | English Attack (move order) | Dodges …Ng4 |
| 6.h3 | Adams Attack (modern) | Quiet prep for g4 |
A couple of move-order things worth knowing
- White can dodge the Open Sicilian entirely. After 1.e4 c5, White isn’t forced to play 2.Nf3 and 3.d4 — the Alapin, Closed, Grand Prix, and Smith-Morra all sidestep it. See how to beat the Sicilian for those.
- The Najdorf is a transposition machine. …a6 followed by …e6 can steer into Scheveningen structures; move orders shuffle constantly. Focus on the resulting structure, not the exact sequence.
The big takeaways
- …a6 is a flexible waiting move — it controls b5 and delays the …e5/…e6 choice.
- The center decision (…e5 vs …e6) defines your middlegame more than any single tactic.
- …b5 is your counterplay — expand on the queenside while White storms the kingside.

FAQ
What is the main line of the Najdorf Sicilian? The defining moves are 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6. From there the English Attack (6.Be3 e5 7.Nb3 Be6 8.f3) is the most important modern main line.
Should I play …e5 or …e6 in the Najdorf? Both are correct — it depends on White’s setup and your taste. …e5 grabs space (but concedes d5); …e6 stays compact and flexible. The whole point of …a6 is to let you choose late.
Do I have to memorize all these moves? For a first outing, no — learn the ideas (control b5, choose your center, expand with …b5, watch the d5-square). The deep memorization only becomes essential in the sharpest English Attack and Poisoned Pawn lines.
