French Defense La Bourdonnais Variation Clearance in Chess

In the French Defense: La Bourdonnais Variation, “clearance” is the tactical idea of making a forcing pawn or piece move that removes a blocker and opens a line (often for the queen, bishop, or rook). A defining feature is the early central tension where Black’s pieces must break through without getting cramped, so clearance typically targets the pawn structure around the d5/c5 squares and the c-file/bishop lines.
