Blackmar Diemer Gambit Accepted Discovered Attack Intermediate Chess Puzzles

In the Blackmar-Diemer Gambit Accepted, White usually follows 1.d4 d5 2.e4 dxe4 and then develops quickly to attack the center and king. The discovered attack theme appears when a piece move opens a line for another piece, often after White has built pressure on e4, f7, or the diagonal toward the black king. For an intermediate player, this motif is about timing: one move creates the threat, and the next move reveals the attack.
