Description: This variation of the Reti opening features a flexible and hypermodern approach by White, fianchettoing the bishop on g2 and castling early. White delays direct central occupation in the opening moves, instead focusing on controlling key central squares from a distance. The move 7.e4 is characteristic here, as it signals White’s intent to challenge Black’s central presence and gain more space in the center.

Characteristic of the Move 7.e4: The pawn push to e4 is a central break that aims to undermine Black’s pawn on d5 and gain a foothold in the center. It reflects White’s transition from a cautious, positional buildup to a more assertive stance, preparing to open lines for the bishops and knights.

Attacking or Defensive: For White, this setup is primarily attacking in nature. The move 7.e4 signals an intention to contest and seize central control, often leading to active piece play and potential kingside pressure. Black’s setup, with ...c5 and ...g6, is solid and somewhat flexible, aiming for a balanced but slightly defensive posture, focusing on controlling central dark squares and preparing counterplay on the queenside or center.

Center Control: Yes, this opening does attack and contest the center. While White initially allows Black some space there, the eventual push with e4 directly challenges Black’s central pawns and aims to establish a strong central presence.
