Sicilian Defense: Najdorf Variation

ECO B90, B94, B95, B96, B98 · 1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 a6

The Najdorf, 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6, is the most famous and deeply analyzed line in chess. The quiet move 5...a6 controls b5, prepares ...e5 or ...e6 and ...b5, and keeps every option open. It was the lifelong weapon of Bobby Fischer and Garry Kasparov.

Plans for White

White has many systems: the English Attack (6.Be3, f3, Qd2, O-O-O and g4), the sharp 6.Bg5 with f4 (including the Poisoned Pawn after 6...e6 7.f4 Qb6), the positional 6.Be2, the Fischer-Sozin 6.Bc4 aiming at e6, and 6.h3 with g4. Most lines involve opposite-side castling and a kingside pawn storm.

Plans for Black

Black chooses between ...e5, gaining central space at the cost of a hole on d5, and ...e6, a flexible Scheveningen-like setup. Queenside counterplay with ...b5-b4, ...Bb7, ...Nbd7-c5 and ...Rc8, plus exchange sacrifices on c3, are the main weapons.

Typical pawn structures

After ...e5, Black's pawns on d6 and e5 leave the d5 square as the key outpost; after ...e6, the 'small center' d6/e6 faces White's e4. In both, the c-file is Black's highway.

Who it suits

Ambitious, well-prepared players who want to play for a win with Black and do not fear sharp theory.

Common traps

Sacrifices on e6, b5 and d5 by White are a constant danger when Black's king is still in the center; Black must also watch the Nd5 jump after ...e5 when the d5 square is weak.
