'''En prise''' (from French "can be taken") <ref>[http://www.chesshistory.com/winter/extra/earliest.html Earliest Occurrences of Chess Terms] by [https://en.wikipedia.org/wiki/Edward_Winter_%28chess_historian%29 Edward Winter]</ref> describes a [[Pieces|piece]] or [[Pawn|pawn]] exposed to a [[Material|material]] winning [[Captures|capture]] by the opponent. This is either a [[Hanging Piece|hanging piece]], a not defended pawn <ref>The ambiguous term [[Hanging Pawns|hanging pawns]] refers a [[Duo Trio Quart (Bitboards)|duo]] of [[Open Pawns (Bitboards)|open]] and [[Isolated Pawns (Bitboards)#IsolanisSetWise|half-isolated]] pawns</ref> , a piece [[Attacks|attacked ]] by a lower valuable attacker, or a piece or pawn defended insufficiently. Any least valuable attacker (LVA) would gain a positive score from a [[Static Exchange Evaluation|static exchange evaluator]] on the [[Target Square|target square]], which also applies to a knight defended by a pawn and attacked by bishop and rook, where the majority of attackers and a least valuable attacker of similar value makes the knight en prise.
