Catalan Opening: Open Defense
Overview
Catalan Opening: Open Defense is a named branch in the Indian Defenses group of chess theory, classified under ECO E04.
The Indian Defenses group covers Indian defences — hypermodern lines where Black challenges the centre with pieces rather than pawns.
The line arises from 10 plies — specifically the moves 1. d4 Nf6 2. c4 e6 3. Nf3 d5 4. g3 c6 5. Bg2 dxc4.
It branches immediately from Indian Defense: Anti-Nimzo-Indian in the opening tree.
Use the board to walk through every move, check how the position has scored on Lichess, or take it head-to-head against Stockfish.
