Immortal Game

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". The Immortal Game is among the most famous chess games ever played. As a miniature game, it is frequently reproduced in chess literature to teach simple themes of gameplay. Although Kieseritzsky himself indicated that the game ended before checkmate, the Immortal Game is frequently reproduced with a brief continuation involving a queen sacrifice—a further loss of material—leading to checkmate. This continuation is commonly presented as part of the complete game, as if the final moves were actually played as part of the real historical game. Some authors also permute certain moves, deviating from Kieseritzky's report, although such permutations typically transpose to distinct lines of play that eventually return to the moves and positions reported by Kieseritzky. Although both players made moves that are regarded as unsound by modern players, the game is appreciated as an example of the Romantic school of chess, a style of play that prized bold attacks and sacrifices over deep strategy. The game—especially its mating continuation—is also appreciated for its aesthetic value, as a plausible example of how a player with a significant material deficit but having an advantageous position can give mate.
