Italian Game Giuoco Piano Trapped Piece in Chess

In the italian game giuoco piano, a “trapped piece” motif happens when a minor piece—most often Black’s bishop on c8 or a knight—gets boxed in by the pawn structure created by 3.Bc4 and the typical c3/d4 setup. The defining feature is that key escape squares are controlled or blocked, so the piece can’t retreat without losing material or tempo.
