Caro Kann Defense Exchange Variation Trapped Piece in Chess

In the Caro-Kann Defense Exchange Variation, the defining feature is the early pawn exchange after 1.e4 c6 2.d4 d5 3.exd5 cxd5, often leading to simplified central structure. A “caro kann defense exchange variation trapped piece” occurs when that simplification leaves a piece with limited squares—commonly a knight or bishop that can’t retreat because the pawn skeleton blocks its escape routes.
