Reti Opening Anglo Slav Variation Trapped Piece in Chess

In the Reti Opening: Anglo-Slav Variation, a “trapped piece” is a tactical motif where one side’s piece (often a minor piece or a pawn structure target) becomes boxed in by pawns and lack of escape squares. The defining feature is the early pawn tension and piece placement that can leave a defender overworked, so the trapped unit cannot retreat without losing material.
