D82 Grünfeld Defense: Brinckmann Attack

D82 holds a single named line. It leaves D80 (Grünfeld Defense) with 4.Bf4. 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 D81 (Russian Variation, Accelerated Variation) comes closest, four squares apart.
