French Defense Steinitz Variation Deflection in Chess

In the French Defense Steinitz Variation, “deflection” is a tactical motif where one side forces a crucial defender to leave its post—often by offering a pawn or creating a threat that must be answered. In practice, it targets the pieces that guard the central dark squares and the c5/d5 breaks typical of this line, so the opponent’s structure or king safety becomes vulnerable after the defender moves.
