Duras Gambit Collinear in Chess

The duras gambit collinear motif is a tactical idea in the Duras Gambit where key pieces line up on the same file, rank, or diagonal, enabling a follow-up strike. After the defining Duras Gambit setup, the opponent’s king and a vulnerable piece often become collinear with your attacking piece, so one move can “unlock” a discovered attack or pin.
