PILLSBURY DEFENCE (main route)
leading to PIRC
White's King's Pawn advances to K4(e4) for an early "classical centre" (the name for a Q4P+K4P formation) - the usual response when Black rejects the chance to occupy the centre (or purposely offers it to White). Usually categorised as a "QP Game" but ECO has Pirc as a KP "main" code line. W-Alt.
