B26 Sicilian Defense: Closed

B26 holds a single named line. It leaves B25, a position of the same name, with 6.Be3. That final move, by the bishop, opens a line for the rook on a1 and the queen on d1. Of all other reference positions, the board of A26 (English Opening: King’s English Variation, Closed System, Full Symmetry) comes closest, ten squares apart.
