Catalan Opening
Queen's Gambit with a g2 fianchetto: long-term pressure on the long diagonal. You play White. The Catalan was introduced by Tartakower at the Barcelona tournament of 1929 and named after Catalonia. White combines the Queen's Gambit with a bishop on g2 that presses on Black's queenside for a long time. Kramnik made it one of the most respected openings of the 2000s.
