The Immortal Game was a chess game played in 1851 between Adolf Anderssen and Lionel Kieseritzky during the London 1851 chess tournament, an event in which both players participated. It was itself a casual game, however, not played as part of the tournament. Anderssen won the game by sacrificing all of his major pieces while developing a mating attack with his remaining minor pieces. Despite losing the game, Kieseritzky was impressed with Anderssen's performance. Kieseritzky published the game shortly afterwards in La Régence, a French chess journal which he helped to edit. Ernst Falkbeer published an analysis of the game in 1855, describing it for the first time with its sobriquet "immortal".
