Four Knights Game Gunsberg Variation Clearance in Chess

In the Four Knights Game, Gunsberg Variation, “clearance” is a tactical idea where White (or Black) plays a pawn move to remove a piece or square that blocks a crucial line. The defining feature is that the position often centers around the c4/d4 and e5/c5 tension, where a timely clearance move enables a follow-up like freeing a knight, opening a diagonal, or preparing an exchange that wins tempo.
