Survive the Italian Game: a6 as Black
The Italian Game: a6 (1.e4 e5 2.Nf3 Nc6 3.Bc4 a6) is a sharp, flexible system White uses to avoid your mainline preparation. After 4.O-O you already have to be careful: across 185,180 games Black wins only 39.7% of the time, while White converts 57.1%. The engine gives +0.61 — a clear edge for your opponent. That means you start slightly worse and need a precise reply. The drill below will train you to hold your own.

By playing a6 before developing, Black prepares to kick the bishop with b5 and gain space on the queenside. White's 4.O-O says: 'I'm not afraid — develop and see what you've got.' The key tension is that a6 can become a weakness if you don't follow up correctly, or a springboard if you do. Your aim is to complete development, keep the centre solid, and avoid falling into a passive position where White's space and activity decide the game.
The Engine's Top Move: Be7
Stockfish's best reply is Be7, preparing to castle and meeting any centre push. The model continuation runs Be7 d4 d6 d5 — Black calmly builds a pawn chain, develops, and asks White to prove the initiative. This line scores only 51.6% for White across 2,334 games, much better for Black than the overall 57.1% figure. Be7 is the antidote to the a6 system: modest but solid, it neutralises White's edge better than any other move.
Avoid the Trap: b5 Is an Inaccuracy
The most-played move — b5 (62,167 games) — is actually a mistake. It scores a terrible 61.5% for White, and the engine says it loses roughly 0.9 pawns of advantage. Why? Because after b5 Bb3, Black has pushed the bishop to a better diagonal, weakened the c6 pawn, and failed to complete kingside development. White gets a free lead in space. The b5 push is tempting but plays into White's hands. Trust the engine and delay queenside expansion.
Which Moves Score Best for Black?
Here are the most-played Black replies and how they perform for you (lower White score = better for Black): Bc5 51.6%, Be7 51.6%, d6 53.5%, h6 54.3%, Nf6 58.4%, b5 61.5%. Both Bc5 and Be7 keep White's scoring under 52% — a huge improvement over the popular but losing b5. Bc5 is riskier but active; Be7 is safer. Either beats the alternatives. The key: get your king to safety and avoid premature pawn pushes.
The Final Plan After Be7
After Be7 O-O, your structure should be: pawns on a6, d6, e5; knights on c6 and f6; bishop on e7; queen on e7 or d7 depending on play. Watch for White's d4 push — when it comes, you usually recapture with the d-pawn (d6 d5) to lock the centre or open it on your terms. Don't grab at the b5 idea until White is committed. Play solidly, castle quickly, and you'll be fighting on equal ground. The Italian Game: a6 loses its sting when you know this.

Frequently asked questions
Is 3...a6 a good move for Black in the Italian Game?
Yes, but it requires accurate follow-up. The move a6 is a popular sideline that controls b5 and prepares queenside expansion. The trouble is many Black players follow with b5 too early. If you reply 4...Be7 and play solidly, you achieve a healthy position. The stats show Black scores much better with Be7 than with b5.
Why is b5 considered a mistake after 4.O-O?
Because b5 allows White to retreat the bishop to b3, where it exerts pressure on f7 and the centre. Meanwhile Black has weakened c6 and delayed kingside development. The engine says b5 loses about 0.9 pawns of advantage compared to the best move Be7. Across thousands of games White scores a crushing 61.5% when Black pushes b5.
Should I play the Italian Game: a6 as Black at club level?
Absolutely — as long as you know the right set-up. At club level most players expect mainline Italian positions and a6 can take them out of book. The key is to avoid the natural-looking b5 and instead play Be7, castle, and meet d4 with d6 d5. It is a perfectly sound system with good practical scoring.
