This opening starts with a direct pawn mirror: White plays for space on the kingside, and you answer symmetrically. After 1.f4 f5 2.d4 d5, the position is balanced and practical. Stockfish rates this +0.22, a small edge for White. That means you are dead level here and should aim for sound development rather than inventing tactics that are not there. The key is to stay patient and make White prove something.
The engine’s best idea
The best move here is c4, and the engine’s line continues with c4 e6 e3 Nf6. That is a useful reminder that the position is still about structure and piece development, not quick attacks. If White pushes in the centre, answer by building a stable setup and keeping your king safe. In this kind of opening, the side that develops smoothly usually gets the more comfortable middlegame.
What the database says White usually does
The most common continuations show that White often chooses simple development: e3 appears in 51,126 games and Nf3 in 43,895 games. Nc3, c3, g3, and h4 are also played, but far less often. That means you should expect White to improve pieces rather than force an immediate confrontation. Your task is to meet those natural moves without drifting into passivity.
Mistakes you can punish
Two moves stand out as known mistakes in this exact position. g3 is an inaccuracy and is said to lose about 0.6 pawns, with e3 as the better move. h4 is worse still: it is a mistake and loses about 1.0 pawns, again with e3 as the better choice. If White weakens the kingside for no clear reason, stay alert and keep your own position compact. The safest practical response is often to let the weakening become a long-term target.

Across 113,600 games from this exact position, White wins 52.0%, draws 5.8%, and Black wins 42.2%.

You are not looking for a miracle; you are looking for a solid game where White does not get more than a slight pull.
