ECO code: A04
Opening Name: Reti: 1...c5, Nimzowitsch-Larsen
Moves: 1. Nf3 c5 2. b3
Description: This opening is a flexible and hypermodern approach where White fianchettoes the queen’s bishop early with 2.b3, aiming to exert long-range pressure on Black’s central and queenside squares. The move 2.b3 supports control of the center from a distance rather than occupying it immediately. White invites Black to occupy the center while preparing to challenge it later with pieces rather than pawns.
Characteristic of this move: The early b3 is characteristic of the Nimzowitsch-Larsen Attack, emphasizing piece activity and control over key diagonal lines. It often leads to asymmetrical pawn structures and dynamic positional play.
Attacking or Defensive: As White, this setup is more positional and strategic than overtly attacking; it is somewhat flexible and can adapt to various plans. Black’s move 1...c5 is a direct attempt to challenge White’s control of the center and can be seen as more aggressive. White’s 2.b3 is not purely defensive but aims to control important squares indirectly.
Center Control: This opening does not immediately occupy the center with pawns but aims to control and influence the center with pieces, especially the bishop on b2 after it is fianchettoed. It is a hypermodern approach that contests the center from a distance rather than direct occupation.
