What is a discovered attack in chess?

A discovered attack happens when one piece moves out of the way and reveals an attack from another piece behind it. It is especially powerful when the moving piece also gives check or wins material with tempo. These tactics often appear in the middlegame and opening when pieces are still uncoordinated.

How do I spot a discovered attack in a chess puzzle?

Look for a line between one of your pieces and an important enemy target, then ask what happens if the front piece moves. If the revealed attack hits the king, queen, or a loose piece, the tactic may be forcing. Also check whether the opponent’s reply is limited by pins, hanging pieces, or king safety.
