B72 Sicilian Defense: Dragon Variation

B72 holds six named lines, all under the name Sicilian Defense. It leaves B70, a position of the same name, with 6.Be3. Queenside castling appears once among its lines, in Sicilian Defense: Dragon Variation, Classical Variation, Grigoriev Variation. That final move, by the bishop, opens a line for the rook on a1 and the queen on d1.
