Ruy Lopez Exchange Puzzle (Rated 1048): Trap a Hanging Knight — Skewer Puzzle with Theory & Hints

A skewer is a long-range tactic in which a single attacking piece — a queen, rook, or bishop — lines up two enemy pieces on the same rank, file, or diagonal. The piece in front must step away, exposing the piece behind it to capture. Here, Black's extra pawn and solid pawn structure are outweighed by a knight that has pushed deep into White's camp with almost no safe retreats. One forcing check reroutes the enemy king, and the loose piece falls, turning a balanced-looking middlegame into a decisive material advantage.
