Blackmar Diemer Gambit Accepted Ziegler Defense Advanced (1.d4 d5 2.e4 dxe4 3.Nc3 Nf6 4.f3 exf3 5.Nxf3 c6) in Chess

Blackmar Diemer Gambit Accepted Ziegler Defense Advanced is an advanced branch of the Blackmar-Diemer Gambit where Black accepts the gambit and then plays the Ziegler Defense setup, leading to a more forcing, tactical middlegame than the main accepted lines. In practice, the defining feature is that Black has taken the pawn and is aiming for active piece play while White tries to convert the extra tempo/initiative into development and central pressure.
