Blunder
Last updated on Mon, 03/31/2008 at 5:28pm.
In chess parlance, a blunder is a thoughtless or ill-advised move, often one that loses a piece, if not the game. A typical blunder might be leaving a piece "hanging" (i.e., undefended, ready for capture), or overlooking a checkmate or other strongly winning move. In short, blunders are immediate, easily-exploitable mistakes.
