Stockfish rates this +0.03, a tiny edge for White. That means you are dead level here — neither side is better out of the opening.
That is the main practical message for Black: there is no need to panic, but there is also no free pass. In a quiet opening like this, the player who develops smoothly and responds to the central tension better usually gets the more comfortable game. Your aim is to keep the position balanced and make White prove something.
The engine’s main answer
The engine’s best move here is Bb2, and the line given continues Bb2 Bg4 Nf3 Bxf3.
For Black, the useful lesson is simple: meet White’s setup with purposeful development and a clear idea for your pieces. The position is not about forcing a tactical race right away. It is about choosing a sensible plan and answering White’s development without letting them build an easy space advantage.
What the database says White usually does
In 6,613,088 games at this exact position, White scores 49.0% wins, 4.0% draws, and Black wins 47.0%. That is another sign that this opening position is very close to balanced.
The most-played continuation is Bb2 with 5,935,534 games, and the next most common tries are e3, g3, Ba3, d4, and Nf3. You do not need to memorise a long branch tree here. It is more useful to understand the character of the position and recognise the moves White is most likely to choose.
One mistake to punish
The main known mistake in this position is g3, which is an inaccuracy and loses about 0.6 pawns; Bb2 was better.
That is helpful for Black because it tells you one White move is already a little too slow or imprecise. When White plays a weaker developing move, stay disciplined and keep your own pieces active. In openings like this, the gain often comes from good development and better coordination rather than from an immediate tactical shot.
