Najdorf Variation - Sicilian Defence
Najdorf (Najdorf Variation of the Sicilian Defence)
Definition
The Najdorf is a celebrated variation of the Sicilian Defence that arises after the moves
1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 a6.
Black’s fifth-move …a6 is the signature move: it prevents White’s minor pieces from using the
b5-square, prepares …b5 to gain space on the queenside, and keeps flexible central options
such as …e5 or …e6. The line is named after Polish-Argentine grandmaster Miguel Najdorf
(1910-1997), who popularised it in top-level play during the 1940s.
Origin & Historical Significance
- Miguel Najdorf first employed 5…a6 in 1939, but its international breakthrough came in the 1947 Prague Tournament.
- By the 1950s it had become the de facto main line of the Sicilian, thanks to adopters such as Svetozar Gligorić and Bobby Fischer.
- Garry Kasparov and Viswanathan Anand both used the Najdorf as their main defence to 1.e4 during their World-Championship years, cementing its reputation as a premier fighting weapon.
Main Move Order and Branches
After 5…a6, White has several sixth-move choices, each leading to its own ecosystem of theory:
- 6. Bg5 – The most aggressive, targeting the pin on f6. Includes the famous Poisoned Pawn line: 6…e6 7. f4 Qb6.
- 6. Be3 – The “English Attack,” where White castles queenside and launches g- and h-pawns.
- 6. Be2 – Fischer’s favourite, heading for a slower positional struggle.
- 6. f4 – The old main line, aiming for a big pawn centre.
- 6. h3 – The Anti-Najdorf (or Adams Attack), stopping …Bg4 ideas.
- 6. a4 – The Gheorghiu Variation, clamping down on …b5.
Strategic Themes
- Queenside space vs. kingside attack: Black expands with …b5 and …Bb7 while White often aims for a direct assault on the black king.
- Flexibility of the e-pawn: Black chooses between …e5 (immediately challenging the knight on d4) or …e6 (more solid, keeps the centre fluid).
- Unbalanced pawn structures: The open c-file and asymmetrical pawns create rich middlegame possibilities and sharp endgames.
- Piece activity over static weaknesses: Even though Black’s d6-pawn can become backward, dynamic piece play usually compensates.
Typical Plans for Each Side
White: Castle long, push g4-g5 or f4-f5, sacrifice material on e6 or b5, exploit the d5-outpost.
Black: Castle short, play …e5 or …e6, pivot a rook to c8, break with …d5 at the right moment, or counterattack on the queenside with …b4.

- Garry Kasparov vs. Veselin Topalov, Wijk aan Zee 1999 – “Kasparov’s Immortal,” an attacking masterpiece with the line 6. Bg5.
- Bobby Fischer vs. Boris Spassky, World Championship (Game 6), Reykjavík 1972 – Fischer’s switch to the English Attack (6. Be3) shocked Spassky.
- Veselin Topalov vs. Vishy Anand, Linares 2005 – A model Poisoned Pawn where Anand’s preparation held a complex ending.
Interesting Facts & Anecdotes
- Miguel Najdorf used to joke that 5…a6 was played so he could “stop annoying white knights from jumping into b5 before I’m ready!”
- The line has its own sub-culture of nicknames: Poisoned Pawn, English Attack, Adams Attack, and even God’s Variation (a humorous reference to the near-divine complexity).
- Modern engines often disagree with human evaluations move-by-move, yet the Najdorf remains a staple even in computer chess at bullet time controls.
- Kasparov’s lifetime score with the Najdorf as Black in classical games: +34 –5 =28 (approximately a 68 % score) .
Why Study the Najdorf?
For competitive players, learning the Najdorf offers a double dividend: it teaches cutting-edge opening theory and hones tactical vision. Even if you never play 5…a6 yourself, understanding its strategic DNA will improve your overall grasp of Sicilian structures.
