Queens Gambit Accepted Gunsberg Defense Clearance in Chess

In the Queens Gambit Accepted Gunsberg Defense, the “Clearance” motif is about forcing a piece or pawn to move away from a critical square so another unit can attack, capture, or open a line. A defining feature is that after the accepted gambit and the Gunsberg setup, Black often needs to clear a defender to make the c- or d-file play work. The clearance is typically tactical: remove a blocker, then exploit the newly opened lane or weakened square.
