How do I spot a trapped piece in chess?

List all legal squares available to the attacked piece and check whether each is occupied, controlled, or illegal because of a pin. A piece is often trapped when its own pawns and pieces remove escape routes while the opponent attacks it with tempo.

What is a skewer in chess?

A skewer attacks a valuable piece while a less valuable piece or target sits behind it. When the valuable piece moves, the attacker can capture the exposed target. Skewers commonly occur along files, ranks, and diagonals.

How does a pin help win material?

A pin restricts a piece because moving it would expose a more valuable target, usually the king or queen. If the pinned piece is also attacked or has no useful squares, the pin can turn a normal threat into a decisive material gain.

What should I look for in a middlegame chess puzzle?

Start with checks, captures, and direct threats, then identify undefended pieces and restricted defenders. Look for pins, skewers, discovered attacks, overloaded pieces, and trapped pieces before considering quiet positional moves.

Francisco Vallejo Pons (Black) Puzzle: Trap a Piece — Trapped Piece

A trapped piece is a tactical target with no safe legal squares, often because its escape routes are blocked by its own pieces or controlled by the opponent. In this middlegame position, a pinned knight and a skewer create the central tactical tension, while loose pawns offer White a way to gain material. The key idea is to recognize that the opponent’s active-looking bishop has helped restrict its own knight and left weaknesses on the queenside.
