Sicilian Defense: Najdorf Anti-English Variation
Sicilian Defense
Definition
The Sicilian Defense is the asymmetrical reply 1…c5 to the King’s Pawn Opening 1. e4. By striking at the d4-square from the flank instead of mirroring White’s central pawn with …e5, Black immediately creates an unbalanced pawn structure that promises counter-attacking chances.
How it is Used in Play
- Main Idea: Prevent White from establishing an uncontested pawn duo on e4–d4 while keeping the important e-pawn in reserve to support …d5 or …e5 later.
- Typical Move-Order: 1. e4 c5 2. Nf3 (or 2. c3, 2. Nc3, 2. d4, etc.).
- Resulting Positions: Sharp, tactical middlegames in which both sides castle on opposite wings are common—especially in the Open Sicilian lines.
Strategic & Historical Significance
With more than a third of all master-level games beginning 1…c5, the Sicilian is the most popular defense to 1. e4. It rose to prominence in the mid-20th century when players such as Miguel Najdorf, Bobby Fischer, and later Garry Kasparov used it as their main weapon against 1. e4, fueling an explosion of opening theory that now spans the ECO codes B20–B99.

Interesting Facts
- Among world champions, only Anatoly Karpov never employed the Sicilian regularly at the highest level.
- The famous Kasparov – Topalov “Immortal” (Wijk aan Zee 1999) began with a Sicilian Najdorf.
- Because the positions are so double-edged, decisive results occur more frequently than in 1…e5 openings.
Open Sicilian
Definition
The term “Open Sicilian” refers to all Sicilian lines where White plays 2. Nf3 followed by 3. d4, exchanging the d-pawn for Black’s c-pawn. The key diagram arises after 1. e4 c5 2. Nf3 d6/…Nc6 3. d4 cxd4 4. Nxd4.
Why Players Choose It
- Space & Initiative: The knight on d4 and pawn on e4 give White a tangible space advantage.
- Theoretical Depth: The Open Sicilian is the most heavily analyzed battleground in chess, appealing to players who enjoy concrete preparation.
- Dynamic Imbalance: Black retains an extra central pawn (e-pawn) and the semi-open c-file, compensating for White’s lead in development.
Main Branches after 4. Nxd4
- Najdorf (5…a6)
- Dragon (5…g6)
- Scheveningen / Classical (…e6 & …d6 structures)
- Sveshnikov (…e5 & …Nc6 knight jump)
- Accelerated Dragon, Taimanov, Kan, and many more

Trivia
The ECO volume devoted to the Open Sicilian (B30–B99) is larger than that devoted to all 1. d4 openings combined!
Najdorf Variation
Definition
The Najdorf is the branch of the Open Sicilian that arises after the moves 1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 a6. The last move preserves the b5-square for Black’s pieces and restrains White’s minor pieces, preparing a flexible …e5 or …e6 break.
Strategic Themes
- Flexibility: Black can choose among …e5 (Poisoned Pawn ideas), …e6 (Scheveningen setup), or …g6 (Dragon-Najdorf hybrid).
- Minor-Piece Maneuvers: The typical route …Nb8–d7–f6 or …Nf6–d7 aims at c5/e5 squares.
- Opposite-Side Castling: Many lines lead to White castling long (Qc2, 0-0-0, g4) while Black castles short and advances …b5-b4.
Historical Notes
Named after the charismatic Argentine GM Miguel Najdorf, who popularized 5…a6 in the 1940s. Bobby Fischer’s near-perfect score with the Najdorf (90 % as Black in his 1972 Candidates run) and Garry Kasparov’s lifelong use cemented its reputation as “the Cadillac of openings.”
Classic Game
Kasparov – Topalov, Wijk aan Zee 1999 featured the spectacular queen sacrifice 24. Qxh7+!! and is often cited as one of the greatest modern games, all springing from a Najdorf.
Anti-English Variation of the Najdorf
Definition
The Anti-English (or “Anti-English Attack”) Variation arises after 1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 a6 6. Be2. White sidesteps the sharp English Attack (6. Be3) and instead adopts a more restrained development scheme.
Purpose & Typical Plans
- Prevent …Ng4: The bishop on e2 guards g4, frustrating Black’s attempts to harass a future Be3.
- Flexible Structure: White may castle kingside quickly, delay f2-f3, and later choose between a central pawn storm (f4, g4) or queenside expansion (a4).
- Positional Grip: By avoiding premature pawn thrusts, White can press against the d6-pawn in slower middlegames.
Key Branches for Black
- 6…e5 7. Nb3 Be7 leading to Scheveningen-style structures.
- 6…e6 7. O-O Be7 8. f4 when both sides retain castling flexibility.
- 6…g6 aiming for a Dragon-Najdorf blend.

Historical & Practical Notes
The name “Anti-English” reflects the line’s original intent: to blunt the ever-popular English Attack spearheaded by English GMs in the 1980s. It has recently enjoyed a renaissance thanks to top players such as Magnus Carlsen, who employed it against Anish Giri in Norway Chess 2021.
Did You Know?
- An early adopter was GM Ljubomir Ljubojević, who used 6. Be2 to upset several Najdorf specialists in the late 1970s.
- The move 6. Be2 keeps Black guessing: after a later Be3, the game can still transpose into the main English Attack, giving White a valuable psychological weapon.
