French Defense Wing Gambit Discovered Attack in Chess

In the French Defense Wing Gambit, White often sacrifices a pawn on the queenside to open lines. A “discovered attack” happens when a piece (commonly a bishop or queen) is unblocked by a forcing move, revealing an attack on a key target—often the king, queen, or a pinned piece—while the opponent’s response is limited. The defining feature is the tactical unblocking that turns the wing-gambit structure into an immediate threat.
