Opening Name: Reti: King's Indian Attack setup, 2...c5 3.Bg2 Nf6 4.O-O Nc6
Moves: 1. Nf3 d5 2. g3 c5 3. Bg2 Nf6 4. O-O Nc6
Description: This variation of the Reti Opening features White adopting a King's Indian Attack (KIA) setup with a fianchettoed bishop on g2 and early castling. Black challenges the center immediately with ...d5 and ...c5, aiming for active piece play and central tension. White’s setup is flexible and hypermodern, inviting Black to occupy the center while planning to undermine it later.
Characteristic: The key characteristic of this line is White’s restrained but flexible control of the center with pieces rather than pawns, combined with Black’s early pawn thrusts in the center and queenside to gain spatial presence. White uses the fianchettoed bishop to exert long-range pressure on the central and queenside dark squares.
Attacking or Defensive: From White’s perspective, this setup is primarily strategic and positional, focusing on controlling key squares and preparing to challenge Black’s center rather than launching an immediate attack. Black’s moves are more directly contesting the center and can lead to active, sometimes aggressive play.
Center Control: The opening involves a hypermodern approach where White delays occupying the center with pawns, instead controlling it with pieces. Black actively challenges the center with pawns, so the battle for central dominance is dynamic and a major theme of the position.
