Stockfish rates this -0.32, a small edge for Black. That means you are slightly better here. The practical message is encouraging: White has already spent time on unusual pawn moves, while you have built a strong central presence with ...d5 and ...e5. In these positions, play is often about staying calm, keeping your centre solid, and not letting White turn the odd opening moves into real pressure.
The engine’s main idea
The engine’s best move here is e3, with the continuation e3 Bd6 d4 e4. That tells you what White is trying to do: open lines and challenge your centre. Your job is to answer with natural development and maintain the space you have earned. In this kind of position, your central pawns are your main asset, so do not rush and do not give them away without a reason.
What the database says White usually tries
Across 332,552 games at this exact position, White wins 45.7%, draws 3.9%, and Black wins 50.4%. The most-played continuations are e3 in 109,439 games, d3 in 82,802 games, d4 in 44,203 games, b4 in 22,482 games, g4 in 13,196 games, and Nf3 in 12,658 games. That means you should expect White to choose one of these quiet or space-gaining ideas rather than launch a direct attack.
The moves to watch for
The known mistake here is g4, which loses about 1.0 pawns; better was e3. Nf3 is also listed as an inaccuracy, losing about 0.5 pawns; better was e3. For you, the lesson is to recognise when White overextends on the kingside and when White simply falls a little short of the best central plan. If White starts pushing too early, your central setup is usually the better foundation.
