Sicilian Defense Open Najdorf Zagreb Variation
Sicilian Defense ‑ Open Najdorf ‑ Zagreb Variation
Definition
The Zagreb Variation is a sub-line of the Sicilian Defense, Open Variation, Najdorf System. The characteristic position arises after the moves:
1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 a6 6. Be2
White’s sixth move—quietly developing the king’s-bishop to e2—was popularised by Yugoslav (today Croatian, Serbian, and Slovenian) masters who trained in Zagreb during the 1950s–70s, hence the name. Modern opening manuals file it under ECO codes B90–B91, sometimes calling it “Najdorf, 6.Be2” or “Najdorf, Classical/Zagreb.”
How It Is Used in Play
Choosing 6.Be2 serves several practical purposes:
- It sidesteps the razor-sharp main lines after 6.Bg5 (the Poisoned-Pawn) or 6.Be3 (the English Attack) that require massive home preparation.
- White keeps the option of castling kingside quickly (7.0-0) while retaining flexibility for central play with f2–f4 or f2–f3, depending on how Black continues.
- Because the bishop stays out of the way of the queen and rooks, plans with Qe1–g3, f4–f5, or even Nd5 can be executed efficiently.
Black, in turn, usually chooses between two main setups:
- …e5 lines – 6…e5 7.Nb3 Be7 8.0-0 0-0, seizing central space and clamping down on d4.
- …e6/…Nc6 Scheveningen hybrids – 6…e6 (or 6…Nc6) aiming for …Be7, …Qc7 and a flexible pawn structure that can transpose into Scheveningen-type middlegames.
Strategic Themes
- Central Tension: White often plays f4 or f3 followed by f4 to challenge Black’s e-pawn and open the f-file.
- Queenside vs Kingside: Black’s minority attack with …b5-b4 can be met by a timely a2–a4, while White tries to drum up kingside pressure.
- Piece Play: Knights frequently maneuver via d5 or f5; bishops eye g4 (for Black) and g5/f4 (for White).
- Transpositional Weapon: Depending on Black’s replies, the game can transpose into Classical, Scheveningen, or even Sozin structures, giving the initiator valuable flexibility.
Historical Significance
The variation owes its rise to the Zagreb chess school, with early contributions from masters such as Svetozar Gligorić, Borislav Ivkov, and Mijo Udovčić. It debuted in top-flight tournaments at Zagreb 1955 and Zagreb 1959, where local players used it to surprise Soviet grandmasters who expected sharper 6.Bg5 lines.
Bobby Fischer adopted the 6…e5 reply for Black (Fischer–Gligorić, Bled 1961) and later refined it against Geller and Taimanov. The line therefore became a battleground for some of the most influential Najdorf discussions of the 1960s–70s.

Both sides retain plenty of play and the position remains objectively balanced yet full of tension.
Famous Encounters
- Gligorić – Fischer, Bled 1961 — Fischer’s 6…e5 showcased Black’s thematic space-grab and inspired a generation of Najdorf players.
- Anand – Kramnik, Wijk aan Zee 1998 — A modern heavyweight duel where Anand used a delayed f4 plan to obtain a nagging edge.
- Kasparov – Polgar, Linares 1994 — Kasparov demonstrated how quickly White’s pieces can spring to life with Qe1-g3 and f4-f5.
Interesting Facts & Anecdotes
- The move 6.Be2 was once dismissed as “harmless” in Soviet literature. Gligorić considered that an advantage, quipping, “If my opponent thinks it harmless, all the better for me!”
- Because it avoids early mutual pawn storms, many top grandmasters use the Zagreb Variation as a “second opening” when they need a solid yet unforced game in must-draw situations.
- In 2013, Magnus Carlsen revived the line against Hikaru Nakamura in a rapid match, proving that even in the engine era the variation holds surprise value.
Summary
The Sicilian Najdorf Zagreb Variation (6.Be2) is a flexible, strategically rich alternative to the heavily analysed Najdorf main lines. By developing quietly and delaying direct confrontation, White forces Black to reveal his hand first, after which plans involving f2–f4, Qe1–g3, or central breakthroughs can be tailored to the specific setup. Owing to its historical roots in post-war Zagreb and its continued practical value, the variation remains an important part of every Najdorf player’s arsenal—whether they seek a safe haven or a fresh battleground.
