Catalan Opening
also known as: Catalan
1. d4 Nf6 2. c4 e6 3. g3
Named after
Named for Catalonia — not a person: the 1929 Barcelona tournament commissioned Savielly Tartakower to devise an opening honoring the region.
Origin
Tartakower's hybrid (queen's-gambit center plus kingside fianchetto) debuted at Barcelona 1929 and slowly conquered elite chess.
The story
Chess's only major opening created on commission, like a symphony: the Barcelona organizers wanted a "Catalan" opening for their 1929 tournament, and Tartakower — the wittiest man in chess history, coiner of "the blunders are all there on the board, waiting to be made" — obliged by fusing 1.d4/2.c4 with g3 and Bg2. The result is a slow-acting poison: the g2 bishop stares down the long diagonal for forty moves, and Black's every freeing attempt feeds it. Fifty years later it became Kramnik's and then the elite's favorite grinding weapon; Carlsen, Caruana, Ding and Nepomniachtchi have all trusted world-championship games to it.
Why it matters
The modern professional's opening of choice for risk-free pressure: minimal theory-forcing, maximal squeeze. The eternal Catalan question — can Black ever fully free the c8 bishop? — has outlasted a century of answers.
