Played the year after the Immortal Game, this is Anderssen's other signature masterpiece — and, fittingly, the one that gave the term "evergreen" to chess literature, after a later annotator called it a game that would "stay fresh forever."
The final combination is a model of quiet efficiency rather than pure material sacrifice: Anderssen offers his queen with 19.Rxe7+, and after Black is forced to recapture, delivers checkmate with both bishops working together — a pure, textbook-clean mating pattern.
As with the Immortal Game, some historians note it was common practice at the time for the losing side to simply resign once the mate was clearly forced and "announced," rather than play out every final move — but the combination itself is completely sound and verified.
