A pin is an attack on a piece that cannot move without exposing something more valuable behind it. When the piece behind is the king the pin is absolute and the pinned piece is legally frozen; otherwise it is relative, and moving it is legal but usually loses material.
Scan the long diagonals and open files for enemy pieces lined up with their king or queen. A pinned piece stops defending whatever it was defending, so the follow-up is often to attack the pinned piece again with a pawn rather than to win it immediately.
