ECO code: A12
English: Caro-Kann Defence 3.b3 Nf6 4.g3
This line arises after the moves 1. c4 c6 2. Nf3 d5 3. b3 Nf6 4. g3. White adopts a flexible and positional setup, preparing to fianchetto the dark-squared bishop with Bg2. The early b3 supports c4 and aims to control the central dark squares indirectly.
Characteristic: The move 3.b3 combined with 4.g3 signals White's intention to build a solid, hypermodern structure, focusing on controlling the center from a distance rather than occupying it immediately. This setup often leads to a slow buildup and strategic maneuvering.
Attacking or Defensive: From White's perspective, this is more of a positional and flexible approach rather than a direct attack. White aims for long-term pressure and central influence rather than immediate confrontation. Black, with typical Caro-Kann solidity, plays a sound and somewhat defensive posture, ready to challenge the center later.
Center Control: White does not directly occupy the center with pawns early on but exerts pressure on the central squares (d5 and e4) through piece placement and fianchettoed bishop. Black occupies the center with pawns on c6 and d5, reflecting the classical Caro-Kann strategy.
