What does x-ray attack mean in chess?

Why are pins so important in chess endgame and middlegame tactics?

Pins reduce the defender's options and can make a piece effectively immobile. In the middlegame, a pin can overload a defender and allow a tactical sequence that wins material. In the endgame, pins often decide whether a piece can be exchanged or a pawn can advance safely.
