The Queen comes out early — 3. Qf3. It looks aggressive, but the engine puts this position at -0.20, essentially dead equal. You are not worse here. In fact, across nearly 2.3 million games Black wins 48.1% and White wins 48.0% — the numbers couldn't be more balanced. Your job is simple: develop naturally, don't panic, and if White pushes too hard, punish them. Below you'll find the engine's top move, the most common continuations, and the three mistakes White makes most often. Play through the position and see if you can tilt the equilibrium your way.

After 1.e4 e5 2.Bc4 Bc5, White brings the queen to f3. The obvious threat is Qxf7# — but your 3...Nf6 already blocks that idea. White hopes to build a quick attack on the kingside, maybe with d3 and g4 later. But bringing the queen out this early comes with risks: it can become a target, and it leaves the king's knight undeveloped. From your side, you are already perfectly placed: your knight attacks e4, your bishop eyes f2, and you can castle quickly. The engine's verdict of -0.20 confirms what the statistics show — this is a clean, level fight.
The Engine's Top Reply: 4. Ne2
Stockfish's best move for White is 4. Ne2, the quiet but solid continuation. After 4...O-O 5.d3 c6, White keeps the position closed and aims for slow development. This line gives White no special advantage — you simply castle, put a pawn on c6 to control d5, and prepare to bring your own pieces out. Don't expect fireworks in this variation; both sides will fight for small positional edges. Your equality is secure.
Three Mistakes White Loves to Make
Statistically, White tries several flashy moves here — and nearly all of them backfire. Based on over 200,000 games each, three stand out as clear errors: g4 is a mistake worth about 1.7 pawns (White should have played Ne2 instead). Nh3 is also a mistake, losing roughly 1.1 pawns. And c3 is an inaccuracy, giving away about 0.8 pawns. If White plays any of these, it is your moment. Against g4, look for a quick ...d5 break. Against the clumsy Nh3, your pieces gain extra squares. Against c3, you can continue developing with ...d6 or ...Nc6, knowing you already have a small edge.
Most Popular Replies — What White Actually Plays
The most common move you will face is 4.d3 (over 760,000 games), where White scores just 49.7% — your equalising task is easy. Next is 4.Nc3 (333,000 games, White scores 49.6%), a natural developing move that is perfectly fine for Black. After 4.h3 (216,000 games, White scores 51.5%) White prevents ...Ng4 but wastes a tempo; you can reply with ...d6 or ...O-O and be happy. Even the sharp 4.g4 (215,000 games) only scores 49.4% for White, despite being labelled a mistake by the engine. Whatever White throws at you, the numbers say you are never worse.
