Immortal Game

The Immortal Game is widely regarded as one of the most iconic and brilliant chess games ever played—a true paragon of the Romantic era. In 1851, Adolf Anderssen captivated the chess world by sacrificing a staggering amount of material—including both rooks, a bishop, and his queen—to deliver a breathtaking checkmate against Lionel Kieseritzky.

So dazzled was Kieseritzky by the brilliance of the game that he telegraphed the moves to his chess club in Paris immediately after it concluded. The game was soon published, and in 1855, Austrian master Ernst Falkbeer fittingly gave it the enduring name it’s known by today: The Immortal Game.

The Players

• Adolf Anderssen: A German master renowned for his aggressive and imaginative style. His victory at the London 1851 tournament established him as the unofficial strongest player in the world and a symbol of Romantic chess.

• Lionel Kieseritzky: A French-based chess master and respected theoretician, Kieseritzky was best known for his sharp analytical mind and for playing countless games at the Café de la Régence. While dominant against amateurs, he often struggled to convert that success against elite opponents.

Without further ado, let’s take a closer look at The Immortal Game!

The King’s Gambit was immensely popular in the 19th century, epitomizing the Romantic era’s fearless and flamboyant approach to chess. Though it has fallen out of favor in modern top-level play due to the advent of computer engines, it remains a beloved choice among adventurous players.

The Bishop’s Gambit—an aggressive but less common line that invites 3…Qh4+, depriving White of castling rights.

This is the Bryan Countergambit, a line deeply analyzed by Kieseritzky and occasionally named after him. While ambitious, it is not considered sound by most modern players.

Threatening …Ng3+ and protecting the pawn on f4. However, it also sidelines the knight—and as the saying goes, a knight on the rim is dim.

An aggressive move that capitalizes on the pinned f5-pawn. While effective in a practical game, modern engines label it as dubious.

Accepting the bishop sacrifice is risky for Black, who is already behind in development and with the queen awkwardly placed.

White now poses two immediate threats:

• Bxf4, trapping Black’s queen, leaving her with no safe escape squares. • e5, attacking the knight on f6 and unleashing a discovered attack on the a8-rook.

This move sacrifices yet another White rook! The idea is to cut off Black’s queen from the defense and set up a lethal mating net.

At this point, Black’s attack has completely fizzled out. Although he has a queen and bishop on White’s back rank, he lacks any real coordination or immediate threats. Meanwhile, White is poised to storm forward with a decisive mating attack.

What an incredible end to an unforgettable game! Despite being massively ahead in material—a queen, two rooks, and a bishop—Black is completely powerless. Anderssen, armed with only two knights and a bishop, delivers a stunning checkmate.
