Catalan Opening: Open Variation
Main Line
1. d4 Nf6 2. c4 e6 3. g3 d5 4. Bg2 dxc4
Overview
Black accepts the gambit-style pawn on c4 — after 4...dxc4, Black temporarily wins material but must defend against White's quick development and long diagonal pressure from the g2-bishop. White's mainlines 5.Nf3 (preparing Qa4+ to win the pawn back) or 5.Qa4+ (immediate recovery) lead to slow positional games where the g2-bishop dominates the long diagonal. The Open Catalan is the principled way to challenge White's setup — used by Anand, Kramnik, and Carlsen as their first-choice Catalan weapon. Pairs naturally with the existing Catalan Closed (E06) entry as the two main Catalan branches.
