A '''discovered attack''' in [[chess]] is placing an opponent's piece, often his king or queen, in jeopardy by moving a piece out of the line of attack in order to activate it.  Then the opponent has to deal with the attack rather than with the piece that was moved to uncover the attack.

An element of surprise is involved because typically the opponent does not see the attack until it is uncovered by moving the piece that was previously blocking.
