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.[citation needed] 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...Bg4 5.d4 Qe7 6.Be3 Nf6 7.Qb3 Nd8 8.Nbd2 g6 9.dxe5 and White was slightly better in LevenfishTolush, Leningrad 1939 (Black won).[2][3][5]
  • 4...Qe7 5.d4 g6 or 5.0-0 g6 is satisfactory for Black (Alekhine).
  • 4...Be6 is preferred by Tartakower.

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:

  • 5. c3 and now:
    • 5...Qd7 and White has some space advantage after either 6.d5 or 6.Bb5 (Keres), or 6.Be3 (Evans).[3]
    • 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,[2] for example: 5... Bxf3 6. Qxf3 and now:
    • 6...Nf6 7.d5 (Unzicker).
    • 6...Qf6 7.Qb3 Nd8 8.dxe5 dxe5 9.Be3 Bd6 10.Nc3 Ne7 11.Nb5 a6 12.Nxd6 Qxd6 13.0-0 Qc6 14.f4! and White had the attack in GavrikovVladimirov, USSR 1978 (Unzicker).

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 Kupreichik–Podgayets, USSR 1970.[3]
  • 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 (SaxIvkov, Amsterdam 1976) with an even game (Unzicker).[6]

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]
