The Queen's Gambit appears in the Göttingen manuscript, written around 1500. It anchored world-championship matches for decades — 32 of the 34 games of Capablanca–Alekhine 1927 were Queen's Gambit Declined — and in 2020 a Netflix series watched by 62 million households emptied the world's chess-set shelves. It isn't even a real gambit: Black cannot safely keep the pawn.
