The Immortal Game.
I've been playing chess all night, and was thinking on the most famous chess game ever played: "The Immortal Game" between Anderssen and Kieseritzky in 1851.
Why is this considered "The Immortal Game"? Because Anderssen captures a total of three pawns, and intentionally sacrifices a bishop, both rooks, and his queen... for the win. It's a stunningly beautiful game.
It's only 22 moves, and if you're interested in seeing it, there's a "one move at a time" play-through (with both forward and back buttons) available here (after you scroll down a bit through the article) :
