Description: This variation of the Reti Opening features White adopting a flexible King's Indian Attack (KIA) setup, fianchettoing the bishop on g2 and castling early. Black challenges the center and queenside with ...c5 and develops knights actively. The move 6...g6 signals Black’s intention to fianchetto the dark-squared bishop, aiming for solid control over the dark squares and preparing kingside safety.
Characteristic: The position embodies a hypermodern approach where White delays direct central occupation, instead controlling the center from a distance with pieces and pawns on d3 and e4 later. Black counters this by striking at the center and preparing a solid yet dynamic setup with ...c5 and ...g6.
Attacking or Defensive: White’s setup is primarily flexible and positional with potential for a slow buildup rather than immediate attacks, so it can be seen as slightly defensive or strategic. Black’s moves are more aggressive in challenging the center and preparing kingside fianchetto, so Black adopts a more active stance.
Center Control: White refrains from occupying the center early, instead controlling it from a distance, while Black actively contests the center with ...c5 and ...d5 pawns. Thus, this opening involves a hypermodern approach to the center rather than immediate direct occupation by White.
