History of the Muzio Gambit
The opening was first analyzed by Giulio Cesare Polerio in the late 16th century.
The first documented game featuring this opening was played by Geronimo Cascio and published in Alessandro Salvio’s “Il Puttino” in 1634.
The name “Muzio Gambit” is attributed to the 19th-century English chess writer Jacob Sarratt, who mistakenly associated the opening with Mutio d’Allesandro, a contemporary of Cascio, in his translation of “Il Puttino”.
The Muzio Gambit was particularly popular during the mid-19th century, the Romantic era of chess, when bold sacrifices and early attacks were highly esteemed.
Its popularity waned with the improvement of defensive techniques by players like Louis Paulsen and Wilhelm Steinitz, but it can still be seen, especially at amateur levels.
