History of Chess Openings
Chess opening theory has evolved dramatically over 500 years, from the romantic gambits of the 1800s to the computer-prepared novelties of today. This guide traces the complete history of how players have chosen their first moves.
The Romantic Era (1600-1850)
The earliest recorded openings: the Italian Game (Greco, 1620s, opening page), the King's Gambit, and swashbuckling sacrifices. Players valued open positions, rapid attacks, and brilliant combinations. Defence was considered ungentlemanly. This era produced the Immortal Game (1851).
The Scientific Era (1850-1920)
Steinitz revolutionised chess with positional principles. The Ruy López (opening page) became the premier opening. Closed games (1.d4) gained respectability. Players began studying openings systematically rather than improvising.
The Hypermodern Era (1920-1960)
Nimzowitsch and Réti challenged classical dogma: you don't need to occupy the centre with pawns, you can control it from the flanks. The King's Indian (opening page), Grünfeld, and Nimzo-Indian emerged as mainstream weapons.
The Computer Era (1990-present)
Databases and engines transformed opening preparation. Novelties are prepared deep into the middlegame. The Sicilian (opening page) dominates at the highest level. AlphaZero's games (2017) revived interest in gambits and unconventional play.
