Ziegler Defense

1.d4 d5 2.e4 dxe4 3.Nc3 Nf6 4.f3 exf3 5.Nxf3 g6

Black meets the BDG with a fianchetto. The king becomes safer quickly, and the dark-squared bishop helps defend key squares. White still tries to use the development lead to generate pressure.

Typical Continuation

White Develops Actively

Bc4 and 0-0

White aims pieces at f7 and hopes to keep initiative before Black consolidates.

Black Finishes the Fianchetto

...Bg7 and ...0-0

Once Black's king is safe, the extra pawn becomes more important and White's direct attack is harder.

Center Control

...c5 or ...e6

Black often challenges the center to avoid being cramped and to trade pieces.

Safety First

The Ziegler is a practical defensive choice: get the king safe, then neutralize White's initiative and simplify.
