Discovered Attack

Moving a piece out of the way to reveal a hidden attack from a piece sitting behind it.

The Tour

The Setup

Look at the long light-squared diagonal. White's bishop on g2 is currently staring at its own knight on e4, but directly behind that knight sits the black queen.

For experienced players

A discovered attack is especially lethal when the masking piece (the one that moves) creates a threat that demands an immediate answer — like a check, a mate threat, or an attack on the queen.
