French Defense Two Knights Variation Clearance in Chess

In the French Defense Two Knights Variation, “clearance” is a tactical/positional idea where one side removes a piece or pawn that blocks a line (often by sacrificing or forcing a capture) to open movement for a key attacker—typically the dark-squared bishop or the queen/rook lines. A defining feature is the early central tension around the d5/e4 squares, where the two-knights setup makes piece coordination and line-opening especially tactical.
