A casual game after the tournament
Two masters sit down in a London tavern. One brings theory. The other brings every piece he owns—and begins giving them away.

I
The room before the storm
Simpson’s-in-the-Strand was thick with cigar smoke and post-mortems. Anderssen, the Prussian schoolmaster, had just become Europe’s unofficial champion. Kieseritzky, the Baltic exile, asked for one more game.
It would not count in the standings. That is why it could become immortal. Scroll slowly: every square below is a decision still warm from the hand.
The score comes alive
Scroll to advance the game. Captured men leave for the rails; the brass gauge follows the position. Use the variation seal to glimpse the road not taken.
II
No clock was on the table
Chess clocks would not arrive for another three decades. Kieseritzky’s tempo came from calculation; Anderssen’s from conviction. We reconstructed the game’s psychological time—not minutes elapsed, but pressure accumulated.

III
Opposite sides of the board
1818—1879
A mathematics teacher from Breslau with a quiet face and a violent imagination. He did not attack because he disliked defence. He attacked because, in the right position, material became a slow currency.
“The pieces may go. The squares remain.”
1806—1853
A celebrated analyst born in Dorpat, feared at the Café de la Régence. He recognized combinations faster than most men could state them—and still found himself trapped inside one.
“To see the net is not always to escape it.”
IV
The wager beneath the moves
Because the queen on f6 is not worth nine points. For one breath, she is worth a tempo. Black’s knight must take her; the knight’s obedience seals the king behind its own army.
Anderssen had already surrendered both rooks and a bishop. By ordinary accounting he was ruined. But chess is not an inventory—it is a geometry of arrival. His remaining bishop could reach e7. Black’s king could reach nowhere.

Kieseritzky sent the moves to La Régence. Ernst Falkbeer published them in Vienna. The name “Immortal Game” arrived years later, once everyone understood that this little tavern game had outlived its players.
