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 revealed attack hits a king, queen, or undefended piece. These tactics often appear in the opening and middlegame.

How do I spot a tactical refutation in the Scandinavian Defense?

Look for forcing moves that exploit development lead, king safety, or loose pieces. In the Scandinavian Defense, central tension and active minor pieces often create tactical chances quickly. Check whether a capture or exchange opens a line against a key target.

Why are pinned pieces so important in chess puzzles?
