Reti Opening: King's Indian Attack Setup with 2...c5, 3.Bg2 Nc6 4.O-O
This variation of the Reti begins with the moves 1. Nf3 d5 2. g3 c5 3. Bg2 Nc6 4. O-O. White adopts a flexible hypermodern approach, developing the kingside fianchetto early and castling quickly to ensure king safety. The move 2.g3 signals White's intention to control the long diagonal and delay direct occupation of the center.
Characteristic: The key feature of this line is White's fianchetto of the bishop on g2 combined with a solid knight development on f3, aiming to exert pressure on Black's central pawns from a distance rather than immediate occupation.
Attacking or Defensive: As White, this setup is primarily positional and flexible, leaning towards a strategic, patient buildup rather than immediate attack. It aims to undermine Black's center indirectly. Black’s ...c5 and ...Nc6 moves challenge White’s control of the center actively, so Black takes a more confrontational stance.
Center Control: White does not directly occupy the center with pawns early on but exerts influence over it with pieces. Black challenges the center directly with ...d5 and ...c5. Overall, the opening focuses on controlling and attacking the center from a distance rather than an immediate central pawn clash.
