The Semi-Italian Opening (also called Lesser Giuoco Piano, Half Giuoco Piano, and Paris Defence) is one of Black's responses to the Italian Game.[1][2] 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.[1][3] The line was tried by Alexander Alekhine early in his career.[3][4] The first recorded use in international competition was in 1846. 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.


Lines

Main line: 4.c3

4.d4

4... Bg4 (after 4...exd4 5.Nxd4 Nf6 6.Nc3 White has the freer game according to Keres; instead of 5...Nf6, Evans has suggested 5...g6!?)[3] and now:

4.h3

White prevents Black's thematic Bg4. The reply 4.h3 leads to lines similar to the Hungarian Defense, for example 4... Be7 5. d4 and now:

4.Nc3

This transposes to the game Maslov–Lutikov, USSR 1963, which continued 4...Bg4 5.h3 Bxf3 6.Qxf3 Nf6 7.Ne2 (or 7.d3) and White stands slightly better (Keres, Filip).[7]
