It branches immediately from Indian Defense: Anti-Nimzo-Indian in the opening tree.
It continues primarily into one named line, Catalan Opening: Closed Variation, Traditional Variation.
Use the board to walk through every move, check how the position has scored on Lichess, or take it head-to-head against Stockfish.
