This opening is not about memorising long theory. It is about staying calm in a symmetrical structure and making a useful developing move when White has spent a flank pawn move. Stockfish rates this +0.24, a small edge for White. That means you are not losing, but you still need to play accurately. The practical goal is simple: meet White’s setup without giving them an easy lead in space or activity.
The engine's best continuation
The engine's best move here is a4. The listed continuation is a4 bxa4 c4 e6, which shows the kind of direct response the engine prefers in this position. That tells you something important: do not sit passively. When White tries to build on the queenside, Black should be ready to react actively and keep the position from becoming comfortable for White.
What the database says White usually does
Across 144,455 games at this exact position, White most often chooses Bb2 with 103,088 games, then e3 with 12,554 games, a4 with 7,297 games, e4 with 4,341 games, a3 with 3,610 games, and Nc3 with 2,479 games. The first two are by far the most common. That means your drill should focus on being ready for a calm developing move rather than expecting an immediate tactical burst.
The mistake to know
The known mistake in this position is Nc3. It loses about 1.0 pawns, and the better move was a4. If White plays Nc3, you should recognise that they have chosen the weaker path and keep your own position disciplined. Do not rush to overpress; just play the better moves and let the disadvantage show itself.
