French Defense Advance Variation Trapped Piece Chess Puzzles

In the French Defense Advance Variation, White usually builds the pawn chain with e5 and d4, creating space but also fixed squares around the center. A trapped piece motif appears when Black or White places a bishop, knight, or queen on a square where the pawn structure cuts off all safe retreats, often after ...Qb6, ...Bd7, or a misplaced bishop on h6 or a knight on d5.
