The Opera Game was an 1858 chess game, played at an opera house in Paris. The American master Paul Morphy played against two strong amateurs: the German noble Karl II, Duke of Brunswick, and the French aristocrat Comte Isouard de Vauvenargues. It was played as a consultation game, with Duke Karl and Count Isouard jointly deciding each move for the black pieces, while Morphy controlled the white pieces by himself. The game was played in a box while an opera was performed on stage.[a] Morphy quickly checkmated his opponents following rapid development of material, involving a queen sacrifice.
It is among the most famous of chess games.[4] The game is often used by chess instructors to teach the importance of piece development, the value of sacrifices in mating combinations, and other concepts.
