Vienna Game: Stanley Variation – How to Punish 4...Nxe4
After 1.e4 e5 2.Nc3 Nf6 3.Bc4, Black often snatches the pawn with 3...Nxe4 — it looks natural, but you've got a powerful reply. By playing 4.Qh5 you immediately attack the e5-pawn and threaten f7. Stockfish evaluates the resulting position at +0.25, a small edge in your favour, and the stats are striking: across over 14,500 games, White wins 66.9% of the time. That doesn't mean the opening wins by itself, but it does mean that club players regularly mishandle Black's position. The drill below will teach you how to keep the pressure on.

When you play 4.Qh5, Black has already taken your e4 pawn and now faces a real test. The engine's top choice is 4...Nd6, blocking your check on e5 and returning the knight to a defensive post. That's the move you should expect from a well-prepared opponent, and the engine continues with 5.Qxe5+ Qe7 6.Qxe7+ Bxe7, trading queens into a quiet endgame where your small edge (+0.25) persists thanks to your lead in development and the bishop pair against Black's damaged pawn structure. However, what makes this opening lethal at club level is that Black has several tempting alternatives — and almost all of them are serious errors.
Three Black Replies You Want to See
Black's most popular move is 4...Nd6 (5,484 games, White scores 50.8%) — perfectly sound. But the next three most-played replies are all mistakes you can punish immediately: g6 (2,099 games): A blunder that loses roughly 4.1 pawns. Black chases your queen, but after you retreat, the weaknesses on f6 and d6 are fatal. White scores 77.1% here. d5 (1,999 games): A mistake costing about 1.4 pawns. Black tries to block your queen's attack on e5, but the knight on e4 is left hanging. White scores 73.6%. Qf6 (1,839 games): Another blunder, losing around 3.1 pawns. Black defends e5 with the queen, but the knight on e4 is still vulnerable and Black's queen becomes a target. White scores 79.3%. If Black plays any of these three, you are already well on your way to a win.
What the Statistics Tell You
Let the numbers shape your confidence. White scores 66.9% overall from this position — nearly 7 wins out of 10. The draw rate is tiny (2.9%), meaning games are usually decisive. When Black avoids 4...Nd6, your winning chances jump dramatically: 77% against g6, 73.6% against d5, 79.3% against Qf6. Even the slightly rarer 4...Ng5 (1,306 games) gives White a 68.8% score. The only truly solid reply is 4...Nd6 (50.8% for White), and even there you hold a small plus. This opening punishes Black's greed — if they don't know the correct defence, they collapse fast.
Your Plan Against the Correct Defence (4...Nd6)
If Black finds 4...Nd6, keep your head. The engine line is 5.Qxe5+ Qe7 6.Qxe7+ Bxe7, heading towards a queenless middlegame where you have more space and better piece activity. Your bishop pair will be a long-term asset, and Black's knight on d6 may become awkward if you can push e4 later. There's no knockout blow here — just sound positional play. Develop your pieces (d4, Nf3, O-O), pressure the centre, and trust that +0.25 edge. Most club players on the Black side aren't going to defend this precisely anyway, and if they slip, you'll have plenty of chances to convert.

Frequently asked questions
Is 4...Nxe4 a good move for Black in the Vienna Game?
No — after 3.Bc4, taking the pawn with 3...Nxe4 allows 4.Qh5, giving White a +0.25 edge and a 66.9% win rate in practice. The knight on e4 is vulnerable to immediate attack, and Black must find the precise reply 4...Nd6 just to stay afloat. Many natural-looking alternatives like g6, d5, or Qf6 are outright blunders.
What is the best move for Black after 4.Qh5?
The engine's top choice is 4...Nd6, which defends the e5-pawn while moving the knight to a safer square. The line continues 5.Qxe5+ Qe7 6.Qxe7+ Bxe7, trading queens into an endgame where White keeps a slight advantage thanks to better development and the bishop pair.
Why is g6 a blunder for Black in this position?
Playing 4...g6 loses roughly 4.1 pawns. Black attacks your queen, but after you retreat, Black has seriously weakened the kingside dark squares and the knight on e4 becomes a huge tactical liability. White scores 77.1% after g6, making it one of the most punishing mistakes Black can make.
How should White respond to 4...d5?
Black's mistake 4...d5 (costing about 1.4 pawns) tries to block your queen's attack on e5. White should take advantage of the hanging knight on e4 — the engine's best continuation involves punishing Black's poor piece coordination. White scores 73.6% from this position, so you are clearly better.
