Catalan Opening: Closed, Main Line
Overview
Catalan Opening: Closed, Main Line is a specific line in the Indian Defenses family (ECO E09), arising from a recognised theoretical position.
The Indian Defenses group covers Indian defences — hypermodern lines where Black challenges the centre with pieces rather than pawns.
It is reached after 18 plies of play, with the move sequence 1. d4 Nf6 2. c4 e6 3. Nf3 d5 4. g3 Be7 5. Bg2 O-O 6. O-O c6 7. Qc2 b6 8. Nbd2 Bb7 9. e4 Nbd7.
The line is a first-level refinement of Indian Defense: Anti-Nimzo-Indian.
