The Vienna Gambit, Max Lange Defense: d6 — Your Guide from White's Side
You've played 1.e4 e5 2.Nc3 Nc6 3.f4 and Black answers with 3...d6 — the Max Lange Defense. After 4.Bb5, the board is set. Over 26,800 games have been played from this exact position, and the results are remarkably close: White wins 52.0% of the time, Black wins 44.2%, and draws are rare at just 3.8%. Stockfish evaluates this at -0.19, a tiny edge for Black that is basically dead level. That means everything is still to play for — and the statistics reveal a critical surprise: Black's most popular reply is actually a mistake. Let's find out how to punish it.

The Max Lange Defense with d6 looks solid. Black shores up the e5-pawn and prepares to develop. The natural move 4...Bd7 seems reasonable — it develops a piece and challenges your bishop on b5. That's why it's the runaway favourite, showing up in over 15,000 games. But the engine says Bd7 is an inaccuracy, losing roughly 0.9 pawns of advantage compared to the best move. Black also often tries 4...a6 (a mistake, losing ~1.1 pawns) and 4...Nf6 (an inaccuracy, losing ~0.9 pawns). All three of these common replies give you, as White, a chance to seize the upper hand if you know how to respond.
The Engine's Answer: Take on f4
Stockfish's top choice is 4...exf4 — Black captures the gambit pawn. That continuation runs: 4...exf4 5.d4 Qh4+ 6.Kf1. Black gives check with the queen, forcing your king to move, but you gain a strong pawn centre with d4. After the engine's recommended line, you have central control and attacking chances. Interestingly, exf4 is the second-most played move in the database (3,446 games), yet Black's winning percentage there is actually lower than when they play the inaccurate Bd7. That tells you: most club players prefer the comfortable developing move over the sharp pawn grab, even though the pawn grab is objectively better.
What the Numbers Tell You
Here's the practical takeaway from the 26,864-game sample. White's best scoring percentage comes against Black's most questionable moves: 4...f6 gives you a 56.8% win rate, 4...a6 gives you 53.5%, and 4...Bd7 gives you 52.1%. Even against Black's best response (exf4, scoring 50.5% for White), you're still winning half the games. The common thread? When Black avoids the sharpest line and plays a 'safe' move like Bd7 or a6, they are actually handing you an edge. Your goal is to know the follow-up so you can capitalise.
Your Plan After Black's Mistakes
If Black plays 4...Bd7, the inaccuracy label means you should have a comfortable game — you can trade bishops on d7 or retreat and maintain pressure. If Black tries 4...a6, that's a clear mistake: you can move the bishop (Bc4 or Ba4 are natural) and keep your attacking setup. Against 4...Nf6, another inaccuracy, you can proceed with normal development. In all these cases, trust your position. The engine says Black should have taken on f4, and since they didn't, you're already slightly better. Keep developing, control the centre, and look for kingside attacking chances — that's the spirit of the Vienna Gambit.

Frequently asked questions
Is the Vienna Gambit, Max Lange Defense: d6 good for White?
Statistically, yes — White wins 52.0% of the time from this position across over 26,800 games. The engine evaluation is -0.19, which is essentially equal, but in practice White scores well, especially when Black plays inaccurate or mistake moves like Bd7 or a6.
What is Black's best move after 4.Bb5 in the Vienna Gambit?
According to the engine, Black's best move is 4...exf4, capturing the gambit pawn. After that the main line continues 5.d4 Qh4+ 6.Kf1. This is the critical test of the gambit. The most popular move in practice, 4...Bd7, is actually an inaccuracy that hands White an advantage.
How do I punish Black's mistake 4...a6 in the Vienna Gambit?
The move 4...a6 is classified as a mistake that loses roughly 1.1 pawns of advantage. You can simply move your bishop — to c4 or a4 — and continue developing. You keep your attacking chances while Black has wasted time pushing pawns instead of developing pieces.
Why is 4...Bd7 an inaccuracy in this line?
Bd7 develops a piece and challenges your bishop, which seems natural, but the engine says it loses about 0.9 pawns compared to the best move exf4. Black misses the chance to grab the gambit pawn and create counterplay with ...Qh4+. Instead, they give you time to build your centre and keep the initiative.
