Pirc Defense Classical Variation Clearance in Chess

In the Pirc Defense Classical Variation, “clearance” is the tactical idea of removing a pawn or piece that blocks a line—most often to open the c- or d-file for your pieces. A defining feature is the Classical setup where Black challenges the center and later needs a clear path for the queen, rook, or bishop to become active. The clearance move creates space for a follow-up tactic (like winning a pawn, gaining an attack, or forcing exchanges).
