The Immortal Game by Bill Wall

http://www.geocities.com/siliconvalley/lab/7378/immortal.htm

The immortal game is one of the most famous games in all of chess. It was played by Adolf Anderssen (1818-1879) and Lionel Kieseritzky (1806-1853) as an informal game, played at the Simpson's on the Strand Divan in London in July, 1851. Anderssen sacrificed his bishop. two rooks, and his queen to deliver checkmate in 23 moves. This may have been a swindle and Black may have resigned in a drawn position, at least prematurely if Black had continued with 20...Ba6 instead of 20...Na6. Black's 20th move may have not even have been played if Kieseritzky really did resign instead of allowing checkmate after 20...Na6, ensuring an immortal combination of a Queen sacrifice that leads to mate after sacrificing a Bishop and 2 Rooks earlier.

Adolf Anderssen was a math teacher from Breslau. He won the 1851 London International, held at the St. George Chess Club, defeating Kieseritzky in the first knockout round, with 2 wins and a draw. He was considered the strongest player of his day.

Lionel Adalbert Bagration Felix Kieseritzky was also a math teacher from Dorpat (now Tartu), Livonia (now inside of Estonia). He was also a chess tutor at the Cafe de la Regence, in Paris, where he gave chess lessons at 5 francs an hour. Two years later, Kieseritsky died penniless in the Hotel du Dieu in Paris, a charity hospital for the insane. No one attended his buriel in a pauper's grave.

The opening was a King's Gambit Accepted, Bishop's variation, Bryan Counter Gambit.

When the game was over, Kieseritsky was so impressed with the game that he telegraphed the moves to his chess club in Paris. The game was publicized in the French chess magazine "La Regence" in July, 1851.

The game was first called the "Immortal Game" by the Austrian player Ernst Falkbeer in 1855.

On September 2, 1923 the town of Marostica, Italy played the immortal game with living persons. They have been recreating this game with living persons every year.

A position of the game after the 20th move has been recreated on a chess stamp from Surinam in 1984.

The final part of the game was used in the 1982 movie "Bladerunner" but the chessboards are not exactly arranged as in the Immortal Game. Sebastian's (Batty) board does not match Tyrell's board.
