The Semi-Italian Opening (also known as Half Giuoco Piano, Lesser Giuoco Piano, and Paris Defence) is one of Black's responses to the Italian Game. It begins with the moves:

1. e4 e5
2. Nf3 Nc6
3. Bc4 d6

Black's intent is to play a Hungarian Defense with an early ...Bg4, fighting for control of the d4-square. The line was tried by Alexander Alekhine early in his career. The first recorded use in international competition was in 1846. I. A. Horowitz called the defence "solid", also writing: "It does not seem quite sufficient for equality."

The Encyclopaedia of Chess Openings code for the Semi-Italian is C50.
