English Opening: Anglo-Indian Defense, Queen's Indian Formation (3.g3 Bb7 4.Bg2)

This opening arises after the moves 1. Nf3 Nf6 2. c4 b6 3. g3 Bb7 4. Bg2. White adopts a fianchetto setup with 3.g3 and 4.Bg2, aiming for long-term control over the central and light squares, particularly the important d5 and e4 squares. Black responds with ...b6 and ...Bb7, mirroring White's fianchetto and preparing to exert pressure on the central and queenside dark squares.

Characteristic: This line is characterized by a hypermodern approach where both sides delay direct occupation of the center with pawns, instead focusing on controlling key central squares from a distance using fianchettoed bishops and knights. The Queen's Indian Formation often leads to flexible pawn structures and rich positional play.

Attacking or Defensive: From White's perspective, this setup is more positional and flexible than outright attacking or defensive. White aims for solid control and gradual buildup rather than immediate confrontation. Black’s moves in the Anglo-Indian Defense are also largely positional, aiming to counter White's central influence and prepare counterplay, making it somewhat balanced between defensive and counterattacking intentions.

Center Control: Both sides focus on controlling the center indirectly rather than occupying it immediately with pawns. White's fianchettoed bishop on g2 exerts pressure on the central squares, especially d5, while Black’s bishop on b7 targets the long diagonal and central dark squares. The battle for the center is subtle and positional rather than direct.
