ECO code: A12
English Opening: Anglo-Indian, 2.Nf3 c6 3.b3
This line arises after the moves 1.c4 Nf6 2.Nf3 c6 3.b3. White's third move, b3, prepares to fianchetto the light-squared bishop to b2, aiming to exert long-range pressure on the central and queenside dark squares.
Characteristic: The move b3 is characteristic for its flexibility and positional nature. Instead of challenging the center immediately with pawns, White focuses on controlling key diagonals and supporting a solid, harmonious piece setup.
Strategic Intent: From White's perspective, this is more of a positional and preparatory approach rather than a direct attack. It does not immediately challenge the center with pawns but influences it indirectly through the bishop on b2. Black, meanwhile, often adopts a solid and somewhat defensive stance with c6, aiming to support ...d5 or prepare ...e5 breaks.
Center Control: This opening does not directly attack the center with pawns early on. Instead, White applies pressure on the center from a distance, aiming to influence central squares indirectly while maintaining flexibility. Black's setup with ...c6 supports potential central pawn breaks, so control of the center remains a key strategic theme for both sides.
