Normal Defence Sub Group (E12.017.NI – E12.026.NI) arises after 1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.e3, where White develops the bishop actively to support the center and prepare smooth kingside development. This setup avoids early confrontation and emphasizes harmony, flexibility, and clear strategic plans.
The Bishop Attack leads to classical Nimzo-Indian structures in which central tension, piece coordination, and timing are paramount. White seeks steady pressure and potential central expansion, while Black counters with solid development and timely pawn breaks, often involving …d5 or …c5.
This Sub Group suits players who value positional clarity, reduced theory, and strategic middlegames within Nimzo-Indian systems.
