After 3...Nf6, you've challenged White's centre in the most direct way. Your knight attacks e4 and your pawn on e5 is solid. The position is almost perfectly balanced — Stockfish gives +0.11, barely a whisper for White. That means nothing is broken from the start; your job is to maintain equality and wait for White to overreach. Many White players do exactly that by choosing moves that look aggressive but actually hand you the advantage. The most common mistake is the tempting f4 push, which sacrifices more than you might expect.
The Engine's Recommended Path
The computer's top choice is d3, preparing to develop the kingside and protect e4. After d3, White's most likely follow-up is Na5 Bb3 Nxb3 — a little knight dance that swaps off your light-squared bishop's attacker. That line is solid and keeps the game close to equal. You don't need to memorise forced replies; the key is to recognise that d3 is the most testing move, and against it you can simply continue developing with natural moves like d6 or Be7, keeping the balance.
White's Most Common – and Costly – Mistakes
Let's look at what White actually plays in practice. The most popular move is d3 (over three million games), but several other continuations are played even though they hurt White's position. Specifically: - f4 is a mistake that loses about 1.1 pawns. White tries to blow open the centre early, but you should welcome this. - a3 is an inaccuracy (loses ~0.6 pawns). This move wastes a tempo and weakens control of the centre. - Qf3 is an inaccuracy that loses about 0.9 pawns. It develops the queen too early and makes it a target. - Nf3, Nge2, and d3 are all sound — but the stats show that Nf3 scores just 49.1% for White, meaning Black scores over half the points in practice.
How to Punish f4, a3, and Qf3
If White plays f4, you should sense opportunity. The engine says it's a clear mistake. Your knights are already developed toward the centre, so look to challenge the f4-pawn with d5 or capture with exf4 if appropriate. After a3, White has weakened the queenside and done nothing to develop — you can simply continue with d6, Be7, and castle, enjoying a comfortable game. Against Qf3, White's queen steps into your half-open file and can become a target after moves like d6 and Be6. The key principle: when White wastes time, you develop. Your natural moves (d6, Be7, 0-0, Re8) are almost always correct.

Yes, it's one of Black's most reliable replies. Stockfish evaluates the position after 3...Nf6 at +0.11, which is essentially equal. In practice Black scores 45.2% wins — a strong number for the second player.
What is the best move for White after 3...Nf6?
The engine recommends d3. That move protects e4 and prepares natural development. After d3, the most common line continues Na5 Bb3 Nxb3, swapping knights on b3.
Is f4 a good move for White in the Max Lange Defense?
No. The f4 push is classified as a mistake costing about 1.1 pawns. It looks aggressive but overextends White's centre, and Black can punish it with accurate play.
What should I do if White plays a3 or Qf3?
Both are inaccuracies. a3 wastes a tempo — just develop naturally with d6 and Be7. Qf3 puts the queen on a vulnerable square; you can target it later while continuing to complete your development.
