Duras Gambit Trapped Piece in Chess

In the Duras Gambit, a “duras gambit trapped piece” is a tactical motif where the opponent’s piece—most often the knight on c6 or the dark-squared defender—gets boxed in by the pawn structure and piece placement after the defining gambit sequence. The key feature is that the trapped piece has no practical squares because the gambit’s pawn breaks and development force it into a net.
