Duras Gambit Discovered Attack Intermediate Chess Puzzles

In the Duras Gambit, the key idea is often to use a pawn sacrifice to open lines while a piece moves with tempo, creating a discovered attack on a more valuable target. For an intermediate player, this means recognizing positions where one piece can step aside and reveal an attack from a rook, bishop, or queen behind it. The defining feature is the hidden line becoming active immediately after the forcing move in the gambit structure.
