The Pin: Immobilizing the Opponent
A Pin is one of the most powerful tactics in chess. It paralyzes an opponent's piece, preventing it from moving because doing so would expose a more valuable target behind it.
Key Pin Concepts
- Absolute Pin: The piece is pinned to the King. It is legally impossible to move it.
- Relative Pin: The piece is pinned to a high-value target (like the Queen). Moving is legal, but usually disastrous.
- Partial Pin: A piece (like a Queen or Rook) is pinned but can still move along the line of the pin.
- "Working the Pin": A golden rule of tactics. If a piece is pinned and cannot move, attack it with more pieces (especially Pawns) to win it!
