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.[6][7] 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.[6][8] The line was tried by Alexander Alekhine early in his career.[8][9] 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."[9]

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

Lines

Main line: 4.c3

4.d4 Bg4

After 4...exd4 5.Nxd4 Nf6 6.Nc3 White has the freer game according to Paul Keres, and instead of 5...Nf6, Larry Evans has suggested 5...g6!?[8] The move 4...Be7 transposes to the Hungarian Defense.

  • 5.c3 and now:
    • 5...Qd7 and White has some space advantage after either 6.d5 or 6.Bb5 (Keres), or 6.Be3 (Evans).[8]
    • 5...Nf6 6.Qb3 with a clear advantage for White (Keres).
    • 5...Qf6 6.Be3 Bxf3 7.Qxf3 with some advantage for White (Keres).
    • 5...Qe7 transposes to the Main line.
  • 5.h3! and White is slightly better,[7] for example 5...Bxf3 6.Qxf3 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:

  • 5...Nf6 6.d5 Nb8 7.Bd3 0-0 8.Be3 a5 9.g4!? (Keres preferred 9.c4) Na6 10.Qd2 c6 11.c4 Nd7 12.Nc3 Ndc5 leading to a sharp game with balanced chances in Viktor Kupreichik–Podgayets, USSR 1970.[8][12]
  • 5...Nxd4 6.Nxd4 exd4 7.Qh5 g6 8.Qd5 Be6 9.Qxb7 Nf6 10.Bxe6 fxe6 11.Qc6+ Kf7 12.Nd2 Qd7 13.Qc4 c5 14.0-0 d5 (Gyula SaxBorislav Ivkov, Amsterdam 1976[13]) with an even game (Unzicker).[14]

4.Nc3

This transposes to the game Maslov–Anatoly Lutikov, USSR 1963,[15] which continued 4...Bg4 5.h3 Bxf3 6.Qxf3 Nf6 7.Ne2 (or 7.d3) and White stands slightly better (Keres, Miroslav Filip).[16] For 5...Bh5?, see Légal Trap.
