About this opening

The Kaulich Defense (5...c5) strikes the center with ...c5 to open the game and activate Black's pieces, contesting the d4 pawn rather than playing passively. Black seeks dynamic counterplay in return for a somewhat open structure. The idea is combative and concrete, the opposite of the compact defenses. A sharp reply to the accepted Blackmar-Diemer, for enterprising players.
