Blackmar Diemer Gambit Discovered Attack Beginner Chess Puzzles

In the Blackmar-Diemer Gambit, White often plays 1.d4 d5 2.e4 dxe4 3.Nc3, giving up a pawn for rapid development and open lines. A discovered attack in this opening usually appears when a developing piece moves with tempo, uncovering an attack from the queen, bishop, or rook on the black king or a loose piece. For a beginner, the key feature is that one move does two jobs: it develops a piece and reveals a hidden threat.
