A00Idée principale des Blancs
White aims to control the b4-square and prepare a quick fianchetto of the queen's bishop (Bb2), pressuring Black's kingside or center. The move 1. b4 also seeks to disrupt Black's standard development by luring the knight to c6, where it can be challenged by b5 or c4 later.
