In chess, a flight square or escape square is a safe square to which a piece, especially a king, can move if it is threatened. Providing one's piece with flight squares can prevent the opponent from winning material or delivering checkmate. For example, in the Morphy Defence, the white c-pawn may be advanced to provide the light-squared white bishop with a flight square. Conversely, it is possible to take away an enemy piece's flight squares, known as domination.
