In chess, the queen is the most versatile piece, moving in any of eight directions; unlike the king, which is constrained to move only one square at a time, she can move in a straight line until another piece is encountered. Translated to logology, this means that any word whose separate letters can be placed on chessboard squares so that it can be spelled out by a king, will also be spelled out by a queen. Furthermore, there will exist some words that can only be spelled out by queen's moves.
