ECO E covers Indian defenses and related systems where Black fianchettoes or pressures the center from the flanks. White builds a pawn center and keeps the position more closed than after 1. e4. This entry tracks a longer branch in the opening tree. Use the diagram and SAN list to recognize the tabiya, then try the line against Maia to explore typical plans in practice.
