Playing the King's Gambit Accepted: Orsini Gambit
The King's Gambit is already a sharp way to start a game — and the Orsini Gambit (3.b3) doubles down on that spirit. Instead of developing a knight or grabbing the centre with 3.Nf3, you immediately challenge Black's extra f4-pawn with your bishop. It's a principled idea, but the engine has a sobering verdict: Stockfish rates this -1.83, a near-winning edge for Black. That means you are already close to losing out of the opening if your opponent plays accurately. But don't close the tab just yet — the statistics tell a more human story, and there are clear ways to improve your chances. Below you'll find the engine's best continuation, the most popular replies you'll face, and which moves your opponents are likely to get wrong.

The numbers don't lie — but they also don't tell the whole story. Across 814 games at this exact position from Lichess, White still wins 42.3% (with 2.1% draws). That's not great, but it's far from hopeless. Black's winning percentage sits at 55.7%. So while Stockfish says you're in serious trouble, real humans on both sides make mistakes. Your job is to be the player who doesn't make them — and who knows how to punish Black's.
Black's Best Move: Qh4+ and the Engine Continuation
Stockfish's top choice for Black is Qh4+. This checks your king immediately, forcing it to move since 3.b3 didn't block the e1-h4 diagonal. The full engine line runs: Qh4+ Ke2 Qe7 Kf2. Black pins your e-pawn, threatens ...Qxe4+, and your king remains exposed on f2. It's uncomfortable, but it's the correct way to play the position. If your opponent knows this line, you'll have to fight hard to equalise. If they don't — and most club players won't — you have real chances.
Most Popular Replies and What They Mean for You
Black's actual move choices in practice are spread across several options. Here is how each one scores for White, and what to keep in mind: - Nc6 (145 games, White scores 46.9%): An inaccuracy that loses about 0.7 pawns. You can now develop more comfortably. - Qh4+ (126 games, White scores 28.6%): The best move. Expect a tough game. - Nf6 (103 games, White scores 34.0%): Another inaccuracy costing roughly 0.7 pawns. Strike while Black develops passively. - d6 (73 games, White scores 53.4%): A mistake worth about 1.3 pawns — your best practical chance. This solid-looking move actually lets you off the hook. - Bc5 (64 games, White scores 53.1%): Also promising for you, as Black ignores the immediate pressure. - d5 (62 games, White scores 35.5%): One of the harder replies to face. Black strikes in the centre.
Punishing Black's Mistakes: d6 and the Inaccuracies
Notice a pattern? The two moves where White scores over 53% — d6 and Bc5 — are precisely the ones Stockfish flags as suboptimal. If Black plays d6, they've made a mistake that costs about 1.3 pawns. That's the moment to seize the initiative with active development and central control, ideally targeting the weakened kingside. The inaccuracies Nc6 and Nf6 each cost roughly 0.7 pawns. While less severe than d6, they still give you a chance to improve your position. In all these cases, your task is the same: develop quickly, keep your king as safe as possible, and put pressure on Black's extra pawn on f4 before they can consolidate.

Frequently asked questions
Is the Orsini Gambit sound?
Objectively, no. Stockfish evaluates it as -1.83, which is a near-winning advantage for Black. However, at club level it scores a respectable 42.3% for White across over 800 games, because Black must know the precise reply (Qh4+) to capitalise fully.
What is the best response for Black against the Orsini Gambit?
The engine's top move is Qh4+, immediately targeting the exposed white king. The full recommended line is Qh4+ Ke2 Qe7 Kf2. If Black plays something else like d6, Nc6, or Nf6, White's winning chances increase significantly.
How should White play after 3.b3 d6?
This is the most common mistake Black can make, costing about 1.3 pawns. White scores 53.4% after d6. You should develop rapidly, control the centre, and aim to challenge Black's f4-pawn. The d6 move doesn't put any immediate pressure on you, so seize the opportunity.
What if Black plays Nc6 in the Orsini Gambit?
Nc6 is an inaccuracy (losing about 0.7 pawns). White scores 46.9% from here, which is better than the overall average. Black develops the knight but doesn't exploit your weakened kingside. Use the tempo to consolidate your position and build an attack.
