Sicilian Defense: Najdorf Variation
also known as: Najdorf
1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 a6
Named after
Miguel Najdorf (1910–1997), Polish-Argentine grandmaster — born Mojsze Najdorf, he stayed in Buenos Aires when WWII broke out during the 1939 Olympiad; his family perished in the Holocaust.
Origin
Developed in Argentine tournaments of the 1940s; 5...a6 became the spine of Black's Sicilian repertoire within a decade.
The story
Najdorf rebuilt his life in Argentina — selling insurance, giving blindfold exhibitions of staggering size partly in hope his family in Poland would read of them — and gave his name to the most analyzed opening variation in chess. The unassuming 5...a6 prepares ...e5 and queenside expansion while taking b5 from White's pieces. Fischer adopted it as a "personal religion"; Kasparov called it the Rolls-Royce of openings and made it his lifelong weapon. Its theory now runs deeper than any other line in the game — thirty-move forced sequences are routine.
Why it matters
The gold standard of fighting defenses: flexible, theoretically dense, and never refuted despite more analytical firepower than any opening in history. Playing the Najdorf well is a professional credential in itself.
