A '''loose piece''' is a [[Pieces|piece]] not defended by own man. Loose pieces and undefended pawns, even if actually not [[Attacks|attacked ]] and therefor [[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.
