English Opening Anglo Indian Defense Trapped Piece in Chess

In the English Opening against the Anglo-Indian Defense, a trapped piece motif appears when Black develops a piece too early and then loses its retreat squares after White’s c4, Nc3, and pressure on the queenside. The defining feature is usually a bishop or knight that becomes boxed in by White’s pawns and minor pieces, often after ...Bb4, ...Bxd2+, or an overextended knight on c6 or b4.
