Plain-English Definition
Pins create pressure without immediate capture. A pinned knight may still look defended, but if moving it exposes the king or queen, the piece is effectively tied down.
Why It Matters
Pins let you convert static pressure into tactics, material wins, or better structure.
Common Signs in Games
- A bishop, rook, or queen lines up with a valuable piece.
- A defender cannot legally move because of the king.
- More attackers can pile onto the pinned piece.
Common Mistakes
- Capturing too early.
- Forgetting the pinned piece may still defend squares.
- Allowing the opponent to break the pin with tempo.
