Englund Gambit Declined Other Variations Trapped Piece in Chess

In the Englund Gambit declined (other variations), the key idea behind the “trapped piece” motif is that Black accepts the gambit only to a point, then uses tempo and piece placement to restrict White’s options. A defining feature is that White’s advanced piece (often the knight that ventured to win the pawn) can become boxed in by pawn structure and limited squares after Black’s follow-up moves.
