The engine’s best move here is d4, and that is the move you should know first. The main continuation given is d4 exd4 e5 Nd5. That tells you the opening is not about passive defence; it is about meeting White’s central idea directly and keeping the game active. If you know this reaction, you will feel much more comfortable when White tries to claim space early.
What the numbers say about this position
This exact position has been reached in 5,787,853 games on Lichess, so the opening is heavily tested. White wins 49.2%, draws 3.8%, and Black wins 47.0%. Those numbers match the engine’s verdict: the position is dead level, with neither side better out of the opening. That makes this a very practical choice if you want a reliable game rather than sharp opening fireworks.

Moves that go wrong for White
The database flags three White moves as especially poor here. Bd3 is a mistake and loses about 1.5 pawns; the better move was d4. Qc2 is an inaccuracy and loses about 0.5 pawns; again, d4 was better. Bc4 is also an inaccuracy and loses about 0.6 pawns; the better move was d4. For you as Black, that is useful because it means White can drift into less effective development if they do not choose the central break.
