Queens Gambit Declined Ragozin Defense Trapped Piece in Chess

In the Queens Gambit Declined Ragozin Defense, the Trapped Piece motif occurs when a side’s piece is forced onto a square where it can’t escape due to pawn structure and piece coordination. A defining feature is the Ragozin setup with ...Nf6 and ...c6 (often after 1.d4 d5 2.c4 e6 3.Nc3 Nf6 4.Bg5 Be7), where central tension and tight minor-piece routes can “lock” a piece in place. The trap is usually created by denying key squares with pawns and controlling escape squares with bishops and knights.
