The Schmid Variation

White developed his queen's knight to QB3(c3), doubling his QP support and planning 4.P-K4.
Black pushes his KKtPawn out to KKt3(g6), planning to fianchetto his KB so as to bring pressure via the long dark diagonal. German IGM Lothar Schmid was W.Ch. chief arbiter in 1972,'78,'86.
