Ruy Lopez: Fianchetto Defense — play it as Black
After 1.e4 e5 2.Nf3 Nc6 3.Bb5 g6, you reach the Ruy Lopez: Fianchetto Defense. As Black, you are choosing a very direct setup with ...g6, and White gets the move in a position where the engine already prefers the first player. That does not mean you should avoid it — it means you need to know what White is trying to do and what your best reply is. Use the drill below to practise the exact tabiya and learn the practical responses that matter most.

Stockfish rates this +0.57, a small edge for White. That means you are slightly worse here.
The position is still very playable, but you should treat it as a line where accuracy matters. White has several natural tries, so your job is to stay calm, meet the central play, and avoid drifting into a passive position. The opening is not about memorising a long forced sequence; it is about understanding the position you have chosen and answering White’s most natural plans efficiently.
The engine’s main idea for Black
The engine’s best move here is c3, continuing c3 f5 d4 fxe4. That tells you what Black is aiming for in this structure: active play and immediate counterplay, not slow waiting moves.
In practical terms, this means you should look for chances to challenge White’s centre and keep the position from becoming comfortable for your opponent. If you can create activity quickly, you are doing the right thing in this opening. The drill helps you recognise this moment and respond with confidence when White enters the tabiya.
What White usually tries
The most played continuation is Bxc6, with 56,929 games and White scoring 50.3%. Other common tries are O-O, c3, Nc3, d3, and d4. These are the moves you are most likely to face, so it pays to know them by feel.
The important lesson is that White has many natural developing moves, and some of them already score a bit better for White than others. Your task is not to guess; it is to understand which setups tend to be the most critical and where White is most likely to press.
The mistakes to punish
The database flags three common inaccuracies in this exact position.
- Bxc6 is an inaccuracy and loses about 0.7 pawns; better was c3.
- Nc3 is an inaccuracy and loses about 0.7 pawns; better was d4.
- d3 is an inaccuracy and loses about 0.6 pawns; better was d4.
This is useful for training because it gives you a clear practical signal: if White chooses one of these less accurate routes, you should not relax. Keep looking for the best continuation and try to make White prove the advantage.
