French Defense Wing Gambit Deflection in Chess

In the French Defense Wing Gambit, “deflection” is the tactical idea of sacrificing or offering a pawn so that Black’s defending piece is forced to move away from a crucial square, file, or diagonal. A defining feature is that White’s early wing pressure (often after the Wing Gambit pawn thrust) creates a moment where Black’s best defender must respond to the threat created by the gambit. The result is usually a tempo gain or a weakened target that White can exploit immediately.
