(The) Longfellner System
Black pushes his King's Pawn out a single square to K3(e6) and frees his queen and (partially) KB but blocks his previously open QB diagonal. Inferior but defensively sound, the Longfellner System teaches safe opening pawn moves to beginners! B-Alt.
White Black Equiv. French route 1. P-K4 P-Q3 (1. P-K4 P-K3) 2. P-Q4 P-K3 (2. P-Q4 P-Q3)
