Vienna Game: Max Lange Defense f4 – How Black Punishes Inaccurate Play
After 1.e4 e5 2.Nc3 Nc6 3.f4 exf4, you have reached the Vienna Game: Max Lange Defense f4. The board is already wide open, and White has to decide how to recover the pawn. Stockfish rates the position at -0.30, a small edge in your favour. Across over 724,000 games from this exact spot, White wins 53.0% of the time, but Black still scores a solid 43.8% — and the engine thinks Black is slightly better. The key is knowing White’s best move (d4) and how to respond when White reaches for something else. The drill below puts you in the Black seat to practice exactly this.

The engine evaluation of -0.30 tells you that Black is already slightly better after 1.e4 e5 2.Nc3 Nc6 3.f4 exf4. That is a meaningful head start for a club player. White sacrificed a pawn to open lines and develop quickly, but in this line White has not yet shown the best follow-up. You are not in a passive or defensive position — you have the chance to seize the initiative if White misplays the next move. The most important thing is to know which moves from White are dangerous and which ones hand you the advantage.
The Best Continuation: 4.d4
Stockfish’s top choice for White is 4.d4. That move continues with the idea of d4 Qh4+ Ke2 Bb4, where White king safety becomes questionable but White gets central control. If White plays 4.d4, the game is sharp. Your queen check on h4 forces the White king to step out, and the bishop to b4 adds pressure. Of the 81,905 games where White played 4.d4, White scored only 50.9% — nearly half the games ended favourably for Black. Compare that to White’s win rate after the more popular 4.Nf3 (53.8%), and you can see that 4.d4 is actually better for White, but still far from crushing.
White’s Most Popular — and Punishable — Choices
The overwhelming majority of players go for 4.Nf3 (599,770 games), but the engine flags it as an inaccuracy that loses about 0.7 pawns compared to 4.d4. White’s win rate after 4.Nf3 is 53.8%, which is solid but inflated by weaker Black responses. Since you are reading this page, you will know how to punish it. Other poor choices include 4.d3 (loses ~0.8 pawns, White scores only 46.1%), 4.Bc4 (loses ~0.9 pawns, White scores 47.0%), 4.Bb5 (White scores a meagre 44.1%), and 4.Qf3 (White scores 44.6%). Each of these is a genuine opportunity for you to convert your opening edge into a win.
What the Drill Will Teach You
This interactive drill starts from the position after 3...exf4 and adapts to whatever White throws at you. If White plays the engine-intended 4.d4, you will practise the sharp queen-check and bishop-bc6 sequence. If White plays a weaker move like 4.Nf3 or 4.d3, you will learn the punishing response that maximises your -0.30 advantage. Over hundreds of thousands of games, Black has scored well in this line — and with the right plans, you can push that win rate higher. The engine will adjust to your level, so you can start simple and gradually face tougher opposition as you improve.

Frequently asked questions
Is the Vienna Game: Max Lange Defense f4 good for Black?
Yes, the engine gives it -0.30, meaning Black is slightly better after 1.e4 e5 2.Nc3 Nc6 3.f4 exf4. This is a sound, active defence that gives Black chances to counterattack, especially if White does not play the best move 4.d4.
What is White's best move after 3...exf4?
The engine recommends 4.d4, followed by Qh4+ Ke2 Bb4. This is the critical test of Black's position. If White plays something else — like the popular 4.Nf3 — the engine considers it an inaccuracy.
Why do most club players play 4.Nf3 if it's an inaccuracy?
4.Nf3 is the most common move by a huge margin (599,770 games) because it develops naturally and looks safe. However, the engine says it loses about 0.7 pawns of advantage compared to 4.d4. Many club players do not know the best continuation, which gives you a great opportunity as Black.
What should Black do after 4.Nf3?
The engine gives you a small edge after 4.Nf3. In general, you want to maintain your extra pawn on f4, develop your pieces actively, and be ready to meet any attempts to regain the pawn. The drill will show you the concrete plans that maximise Black's chances in this line.
