The Semi-Italian Opening, also known as Half Giuoco Piano, Lesser Giuoco Piano, and Paris Defense, is an intriguing and somewhat unorthodox response by Black to the Italian Game.
Employed by famous grandmasters such as Alexander Alekhine, the Semi-Italian Opening has evolved over the years to create numerous variations.
Here we look into the detailed aspects of the Semi-Italian Opening, analyzing the opening’s move order, theory, strategy, purpose, variations, and its historical roots.
It will also discuss how suitable this opening is for beginners and intermediates, and how often it’s played at the Grandmaster Level.
Move Order of the Semi-Italian Opening
The Semi-Italian Opening’s initial moves are as follows:
- e4 e5
- Nf3 Nc6
- Bc4 d6
The intent of Black is to opt for a Hungarian Defense with an early …Bg4, thereby fighting for control of the d4-square.
This formation, tried by Alexander Alekhine in the early stages of his career, showcases Black’s defensive capabilities while also setting up opportunities for later offensive action.
Theory, Strategy and Purpose of the Semi-Italian Opening
The Semi-Italian Opening is fundamentally a defensive strategy for Black.
By choosing this opening, Black is trying to maintain a solid structure, aiming for control of the d4 square.
The Semi-Italian Defense allows Black to utilize the bishops on the g4 and e7 squares, challenging White’s control of the center.
Additionally, it allows Black to keep a compact structure, making it more difficult for White to exploit any weaknesses.
However, as stated by I. A. Horowitz, it does not seem to provide complete equality, indicating that White may still have some edge.
Variations of the Semi-Italian Opening

This line can transpose into the Hungarian Defense if Black chooses 4…Be7.
4.d4 is considered the strongest move in the Semi-Italian Opening (+0.50 evaluation for white).
4.h3 Variation
