Hungarian Opening: Reversed Norwegian Defense
You've just played 1.g3 e5 2.Nf3 e4 3.Nh4 — and Black is already pushing your knight back. This is the Hungarian Opening: Reversed Norwegian Defense, an offbeat line that often catches opponents off guard. The position is dead level (Stockfish says -0.10, a tiny plus for Black, so you are even). But in practice, Black scores well: across nearly 10,000 games, Black wins 55.5% to White's 41.1%. That gap suggests many White players aren't handling this position well. Below the interactive drill, you'll learn how to fight back, which replies to look out for, and the one black move you should be ready to punish.

After 1.g3 e5 2.Nf3 e4 3.Nh4, the central tension is clear: Black has pushed past your knight and claimed space on e4, while your knight sits awkwardly on h4. The engine evaluates this as -0.10, a microscopic edge for Black — basically a draw with perfect play. Your task is to prove the knight on h4 isn't misplaced. You'll want to challenge Black's centre quickly, often with a quick d5 or a timely d3, opening lines for your pieces while Black's advanced e4-pawn can become a target if they overextend. The king is safe on g1 behind the fianchetto, and your lightsquared bishop on b2 or a3 will have a long diagonal to work with.
The Engine's Blueprint: Play d5
The engine's top choice after 3.Nh4 is d5. Black should then continue with d5 d3 f5 Bh3 according to Stockfish's main line. That sequence shows a typical plan: White challenges the centre with d5, then cracks open the position with d3, forcing Black's f-pawn forward before developing the bishop to h3, pressuring Black's king-side or the f5-pawn. You don't need to memorise this exact line move for move, but the pattern is instructive. If Black plays something else — and they often do — your plan remains the same: target the centre and trade Black's advanced pawns before they become a permanent space advantage.
What the Statistics Reveal
Black has tried dozens of replies from this position, but five account for the vast majority of games: - d5 (4,204 games) — White scores just 39.0%, Black's most successful reply - Be7 (2,122 games) — White scores 38.9%, another tough result - g5 (1,734 games) — White scores 42.1%, a bit better but still losing - Nf6 (659 games) — White scores 47.6%, much more promising - Bc5 (331 games) — White scores 46.5% - Nc6 (246 games) — White scores 47.6% The numbers show that White's results improve sharply when Black develops naturally (Nf6, Bc5) rather than pushing the d- or g-pawn. The worst lines for White involve d5 and Be7, where Black keeps the centre closed and you struggle to free your pieces.
The Mistake to Punish: g5
One of the most instructive facts about this position: g5 is an actual mistake that loses Black about 0.6 pawns of advantage. The correct move was d5. When Black plays g5, they lunge at your knight and weaken their kingside, creating holes on f5 and f6. The engine says better was d5, so if your opponent chases your knight with g5, you should be happy — your position just improved. You can retreat the knight to g2 or f3, and Black's kingside light squares become inviting targets for your bishops. In the Lichess database, after g5 White scores 42.1%, which is better than after d5 (39.0%) — a small but real edge in practice.

Frequently asked questions
Is the Hungarian Opening: Reversed Norwegian Defense a good opening for beginners?
Yes. The position is strategically simple and doesn't require memorising long theory. The engine gives it -0.10, dead even, so you're not playing a bad opening. Beginners can learn useful themes like fianchetto development, central breaks with d3/d5, and how to handle an advanced enemy pawn.
What is Black's best reply to 3.Nh4?
According to the engine, **d5** is Black's strongest move. It's also the most popular, appearing in over 4,200 games. After **d5**, White scores only 39%, so it's the reply you should be most prepared for. A quick **d3** break is the typical answer.
Should I be scared of Black playing g5?
No — this is actually a mistake for Black. The engine says g5 loses about 0.6 pawns of advantage compared to the best move d5. While White still scores 42.1% after g5 in practice, that's better than after d5. Punish it by retreating your knight and targeting the weakened kingside light squares.
Why does White score so poorly (41.1%) if the position is dead equal?
Practical play differs from engine evaluation. The knight on h4 looks awkward, and many White players feel uncomfortable or don't know the right plan. Black also has an easy idea: push in the centre. The statistics suggest that with the right approach — central breaks and patient development — you can improve your results significantly.
