A '''hanging piece''' is an [[Attacks|attacked ]] [[Pieces|piece]] not defended by own man exposed to [[Captures|capture]]. While hanging is often used synonymously with being [[En prise|en prise]], the latter actually requires not necessary undefended, but also defended insufficiently. To avoid confusion with [[Hanging Pawns|hanging pawns]], which refer a [[Duo Trio Quart (Bitboards)|duo]] of [[Open Pawns (Bitboards)|open]] and [[Isolated Pawns (Bitboards)#IsolanisSetWise|half-isolated]] pawns, undefended or loose pawns are therefor not called hanging. [[Loose Piece|Loose pieces]] and undefended pawns, even if actually not attacked and [[En prise|en prise]], may be considered in [[Evaluation|evaluation]], specially if there are more than one or even two per side, and the opponent has forces and possibilities for [[Double Attack|double attacks]] and [[Knight Pattern#KnightForks|knight forks]]. [[Game Phases|Game phase]], an exposed [[King|king]] and the presence of the opponent queen can be considered as well in that evaluation term.
