Englund Gambit Declined Interference in Chess

“Englund gambit declined interference” is a tactical motif in the Englund Gambit where Black declines the gambit and uses the resulting piece alignment to create (or prevent) interference on a critical line. A defining feature is that after the gambit is declined, White’s pieces often aim at a key square/line, while Black’s setup allows a move that disrupts that plan by forcing a piece to block or a defender to be displaced.
