In chess, a discovered attack is an attack revealed when one piece moves out of the way of another. 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 succeed because the opponent is unable to meet two threats at once. While typically the consequence of a discovered attack is the gain of material, they do not have to do this to be effective; the tactic can be used merely to gain a tempo. If the discovered attack is a check, it is called a discovered check.
Famous quotes containing the words discovered and/or attack:
“Then I discovered that my son had learned something new. For the first time, he was able to give a proper kiss, puckering up his lips and enfolding my face in his arms. “Kees Dada,” he said as he bussed me on the nose and cheeks. No amount of gratification at work could have compensated for that moment.”
—Donald H. Bell. “Conflicting Interests,” New York Times Magazine (July 31, 1983)
“Philosophy can be compared to some powders that are so corrosive that, after they have eaten away the infected flesh of a wound, they then devour the living flesh, rot the bones, and penetrate to the very marrow. Philosophy at first refutes errors. But if it is not stopped at this point, it goes on to attack truths. And when it is left on its own, it goes so far that it no longer knows where it is and can find no stopping place.”
—Pierre Bayle (1647–1706)
