King's Gambit: Playing the exf4 Line as White
You've pushed the f-pawn, sacrificed material, and now face the defining moment of the King's Gambit: 3...exf4. Black has accepted your gambit, grabbing a pawn. The position is sharp, but the engine gives -0.74 — a clear edge for Black, meaning you are slightly worse from the start. Don't panic: the statistics show White still scores 54.5% in practice across nearly 20 million games on Lichess. The difference between engine evaluation and real results tells you this is a tricky, double-edged opening where your opponent can easily go wrong. The drill below puts you in the hot seat to find the best responses.

The King's Gambit isn't about a material deficit — it's about time and attacking chances. By playing 2.f4 you offered a pawn to open the f-file, pull Black's e-pawn away from the centre, and seize control of d4. After 3...exf4, Black has taken the bait. Your job is now to develop quickly and build pressure, especially against the kingside and the f4-square where Black's extra pawn sits exposed. The engine's -0.74 rating shows this is objectively risky, but the practical winning percentage (White wins 54.5%) proves that in real games, Black often struggles to hold their advantage. Your compensation comes from active piece play, not from regaining the pawn immediately.
The Engine's Best Path: g5
At depth 16, Stockfish's top choice is 4...g5 — Black reinforces the f4-pawn and prepares to push ...g4 to drive your knight away. The full engine continuation runs: 4...g5 5.d4 d6 6.h4. That last move, 6.h4, aims to undermine Black's pawn chain by threatening ...hxg5. From your perspective as White, this is the critical line to understand. You'll have to decide between playing for a quick attack or allowing a slower positional battle. Don't be afraid of ...g4 — after 6.h4, Black's kingside pawns can become targets rather than strengths, especially if your queen and bishop get aimed at the h-file.
The Stat That Matters Most: 57.0% with 3...Nf6
Among all Black replies, 3...Nf6 gives White the highest winning percentage at 57.0% (from 2,120,503 games). This natural developing move is perfectly playable for Black — it doesn't lose material or give up control — but it also doesn't disrupt your plans. After 3...Nf6 you can continue developing with d4, Bc4, or even Nc3. Compare that to 3...Be7, where White's score drops to just 47.3% across 1,663,925 games. That difference of almost 10 percentage points shows that Black's bishop move to e7 is a surprisingly effective defensive idea. Know these stats: when Black plays an unambitious move like 3...Be7, you need to be more careful than when they contest the centre with ...Nf6.
The Most Common Mistake: 3...Nc6
According to the statistics, 3...Nc6 is the single most-played reply (3,825,305 games), but the engine flags it as an inaccuracy that loses about 1.0 pawns of advantage compared to the best move 4...g5. That's a golden opportunity for you. After 3...Nc6, Black develops a knight but doesn't support the f4-pawn or address the threat of d4. You can immediately punish by playing 4.d4, opening the centre while Black's knight is poorly placed to block. The resulting positions are sharp and favour active play — exactly what the King's Gambit player wants. Watch for opponents who blindly follow old habits; 3...Nc6 is a gift when you know how to respond. Use the drill below to practise punishing this inaccuracy.

Why does 3...Nc6 lose so much advantage for Black?
