Trapped Piece Puzzle (Rated 2235): Pin — Trapped Piece

A trapped piece is not always lost immediately. The defender may have a tactical resource that changes the geometry of the position, creates a counter-threat, or removes the attacker’s coordination. Here, Black’s extra material is under pressure because a knight is attacked, pinned, and restricted. The key defensive idea is to find a move that addresses several threats at once while preserving the material advantage. This is a classic middlegame lesson in turning passive defense into active counterplay.
