In [[chess]], a '''discovered attack''' is a direct attack revealed when one piece moves out of the way of another.<ref>[http://www.chesscorner.com/tutorial/tactics/discovered/discovered.htm Discovered Attack] Article at Chesscorner.com</ref> Discovered attacks can be extremely powerful, as the piece moved can make a threat independently of the piece it reveals.  Like many [[chess tactics]], they often succeed because the opponent would be unable to meet two threats at once unless one of the attacked pieces can simultaneously move away from its own attack and capture the other attacking piece.  While typically the consequence of a discovered attack is the gain of {{chessgloss|material}}, they do not have to do this to be effective; the tactic can be used merely to gain a [[tempo (chess)|tempo]].<ref>[http://www.markalowery.net/Chess/Tactics_Strategy/Tactics_Lesson2/tactics_lesson2_index.html More detailed tutorial] at MarkLowery.net {{dead link|date=June 2016|bot=medic}}{{cbignore|bot=medic}}</ref>  If the discovered attack is a [[check (chess)|check]], it is called a ''discovered check''.
