This game was played as a friendly aside to the 1851 Great Exhibition tournament – the first ever international chess event – which Anderssen won. His opponent, Kieseritsky, was chess tutor at the Cafe de la Regence, in Paris, where he gave lessons at five francs an hour.

The vanquished Kieseritsky was so impressed by the brilliance of Anderssens play that he immediately telegraphed the moves to an awaiting audience in Paris, and the game ever since has been known by the unimproveable sobriquet, the Immortal Game.
Moves and a diagram from the game later appeared on German 75 pfennig currency coupons in the 1920’s.
