Sicilian Defense: Najdorf Variation, English Attack

This move develops a piece, and prepares to castle queenside.

The English attack, starting after Be3, f3, Qd2, and O-O-O, leads to slower positions than the more active Bg5 Najdorf. White first plans to castle queenside before launching g4, h4, g5, h5, etc for a ferocious kingside attack. Black on the other hand gets stronger control of the center with e5, and more liberated pieces.
