French Defense Mediterranean Defense Trapped Piece in Chess

In the French Defense Mediterranean Defense, a “trapped piece” motif occurs when a piece—often a knight or bishop—gets boxed in by the pawn structure and limited squares. A defining feature is the cramped, semi-closed center where Black’s pawn breaks and piece placements restrict the trapped unit’s escape routes. The result is that the opponent can win material by forcing the piece to remain immobile or by threatening a follow-up that seals its fate.
