The bishop on b5 pins your knight to the king and threatens to capture it, which would double your c-pawns. That is the immediate tension. Your 3...g6 is a principled reply: you fianchetto your king's bishop to control the long diagonal, preparing to castle quickly and challenge the centre from afar. You are not running from the pin — you are accepting that White may take on c6, and you are betting that the bishop pair and dynamic piece play you get in return outweigh the damaged pawn structure. The engine evaluation of +0.15 is essentially nothing; your position is fully sound and the game is just beginning.
The Most Popular Reply: Bxc6
White's most common move by a wide margin is 4.Bxc6, appearing in 87,116 games. White scores only 49.7% here, barely above even. After 4...dxc6, you will have the two bishops and a half-open d-file. Your light-squared bishop is free to develop to e6 or f5, and your dark-squared bishop belongs on g7, eyeing the centre. The doubled c-pawns are not a weakness right now — they control d4 and b4. Your plan is straightforward: finish development with Nf6, O-O, and then decide whether to push ...e5 or ...c4 to clamp down on White's space. Do not rush; your position is solid and your bishops gain value as the board opens.
When White Plays the Engine's Best: 4.Nf3
The engine's preferred continuation is 4.Nf3, which has been played 25,988 times in practice. Notice that White scores only 45.1% from this line — lower than after the automatic Bxc6. After 4.Nf3 Bg7 5.O-O Nd4, you immediately challenge the knight on f3 and the bishop on b5. This is a sharp, active approach. Your knight on d4 is well-placed and may force White to spend time dealing with it (e.g., Bc4, or Nxd4 followed by cxd4). You have already equalised comfortably. The key insight: White's most accurate move actually gives you a higher win rate than any of the alternatives.
Punishing White's Inaccuracies
Two moves by White are flagged as clear inaccuracies, each losing about half a pawn compared to 4.Nf3. 4.f4, played 15,963 times (White scores 49.6%), weakens the e4 pawn and opens lines for your bishops. Your reply is straightforward: develop with ...Bg7 and look to strike in the centre. 4.b3, seen in 1,457 games (White scores just 42.8%), is a slow attempt to fianchetto the queen's bishop. This is the move you most want to face — your winning chances are already above 57%. Simply develop naturally with ...Bg7, then ...Nf6, and you will have more than enough play. Against both inaccuracies, remember that White has spent a tempo on a second-best idea, and you can use that extra time to seize the initiative.
