checkmate

Checkmate (Persian: كيش و مات ، kish-o-mat Means King is Defeated) (often shortened to mate) is a game position in chess (and in other board games of the chaturanga a word with persian origin: چترنگ Chatrang family) in which a player's king is in check (threatened with capture) and there is no way to remove the threat. Checkmating the opponent wins the game.

Checkmate, a division of Task Force X, is a fictional covert operations agency within the DC Comics universe. It first appeared in Action Comics #598 and proceeded to have its own ongoing title in Checkmate!. In the wake of events depicted in the mini-series The OMAC Project and Infinite Crisis, Checkmate had been re-chartered as a United Nations Security Council-affiliated agency and had its own series, Checkmate (vol. 2).
