fxe4 Puzzle (Rated 1145): Pin — Win Material

A pinned piece can look protected while actually being unable to move. In this middlegame position, Black must recognize that a valuable rook is restricted by the king behind it. The key idea is to exploit the opponent’s last move: a pawn capture changes the lines of attack and exposes a tactical refutation. This transforms White’s apparent advantage into a material loss, showing how a hanging piece and an absolute pin can decide a position quickly.
