Najdorf Variation

An Open Sicilian variation in which Black plays ...a6 to control b5 and preserve several possible central structures.

A system against the Najdorf beginning with Be3 and often followed by f3, Qd2, and a pawn attack against Black's king.

A Najdorf branch full of concrete threats in which Black's queen captures on b2 and accepts danger in return for a pawn.
