Welcome! I'm Luka, and today we build a Najdorf repertoire for Black. The Najdorf is the most trusted defense to 1.e4 — flexible, aggressive, and endlessly rich. The move ...a6 looks modest but controls b5 and prepares ...e5 or ...e6 depending on White. You will play the black pieces here. When White plays 1.e4, answer with ...c5.Play pawn to c5.
