Semi-Italian Opening (Theory, Variations, Lines)

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:

  1. e4 e5
  2. Nf3 Nc6
  3. Bc4 d6
Semi-Italian Opening - 1. e4 e5 2. Nf3 Nc6 3. Bc4 d6
Semi-Italian Opening – 1. e4 e5 2. Nf3 Nc6 3. 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

There are several variations within the Semi-Italian Opening that can be explored based on different strategies:

Main Line Variation

This involves the sequence 4.c3, and then it can further branch out depending on Black’s fourth move. Notable sub-variations include 4…Bg4, 4…Qe7, and 4…Be6.

4.d4 Variation

This includes the move 4…Bg4 by Black and offers another path to the game.

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

This move by White prevents Black’s thematic …Bg4, and it can lead to lines similar to the Hungarian Defense.

4.Nc3 Variation

This move can transpose into a game sequence seen in the game Maslov–Anatoly Lutikov, USSR 1963.

Each variation can significantly change the dynamics of the game, allowing for diverse strategies and game plans.

4.O-O Variation

Castling is a safe option as well.

It is generally considered the second-strongest move after 4.d4 with a +0.40 evaluation for white.

4.a4 Variation

4.a4 works by expanding on the queen-side and is a more modern twist on the Semi-Italian Opening.

It’s the third-strongest move after 4.d4 and 4.O-O, with a +0.30 evaluation for white.

Evaluation of the Semi-Italian Opening
