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:
“I have found it; I have discovered the cause of all the misfortunes which befell him. A public school, Joseph, was the cause of all the calamaties which he afterwards suffered. Public schools are the nurseries of all vice and immorality.”
—Henry Fielding (1707–1754)
“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)
