blitz
n.— «Shawn comes to Wall Street to play a type of chess called blitz, a game in which the ticking of a three-minute clock eliminates the ponderous pauses of traditional chess and transforms the game into a fevered, trash-talking street sport in which money, not prestige, is the prime motivator. For Shawn, a large bet might be $10 a game.» —“Teenage Riddle: Skipping Class, Mastering Chess” by Timothy Williams New York Times Mar. 13, 2007. (source: Double-Tongued Dictionary)
