Chess Pin Attack:
Part of the Chess Tactics Guide
A Chess Pin attack is one where an attacking piece forces an enemy piece to remain where it is, else risk the loss of a more-valuable piece, directly behind.
Such an attack could be used to either capture the 'Pinned' piece, or prevent the enemy from moving that piece, which may prove a larger threat to your plans.
Pin Attacks are performed by any of the three long-range pieces:
Furthermore, Pins can be either Relative, which means their victim is 'pinned' against any Piece, except their King, or Absolute, meaning the shielded Piece IS the enemy King.
Below, you can access a series of mocked-up Pin Attacks, for each of the three pieces, with both a Relative and Absolute alternative ...
