Blackmar Diemer Gambit Other Variations Discovered Attack in Chess

In the Blackmar-Diemer Gambit, the "other variations" often arise after White has gambited a pawn and developed quickly, creating lines where a piece move uncovers an attack on a key target. A discovered attack in this setting usually appears when a bishop, rook, or queen is revealed to hit the black king, queen, or a loose central piece after a developing move or capture. The defining feature is the hidden line of attack becoming active because one piece moves out of the way.
