Petrov's Defense: The Stafford Gambit Nxf7 Line
After 1.e4 e5 2.Nf3 Nf6 3.Nxe5 Nc6 4.Nxf7, White grabs a pawn with the knight — but the capture comes at a steep price. After 4...Kxf7, you've given up castling rights, but you've gained a massive lead in development and activity. Stockfish rates this position at -2.24, a near-winning advantage for Black. That means you are winning from here — if you know how to handle White's best attempts. The drill below will teach you how to punish White's most common responses and convert your edge.

White has one extra pawn but a king stuck in the centre, lagging development, and exposed pieces. You, on the other hand, have a centralised king that's actually safe for now, two developed knights, and a pawn on e4 ready to be challenged. Your main idea is immediate: strike in the centre with d5 after appropriate preparation, or exploit the weak f2-square and the open f-file. The engine's top choice for White is d4, which tries to close the centre and return some material to consolidate. But in practice, White players rarely find the best move — and when they don't, your advantage can grow into a quick win.
The Best Move for White (and How to Answer)
The engine says White should play 5.d4. This aims to block your centre counterplay and prepare rapid development. The best follow-up continues 5...Nxe4 6.d5 Qf6, when your queen comes to f6 with tempo, pressuring f2 and threatening nasty checks. Your knight on e4 is a monster — it attacks f2 and can't easily be dislodged. From here you have excellent compensation and the engine still sees a clear advantage for you. Even when White plays correctly, you're the one pushing for more. Study this line well, because it's the hardest test you'll face.
The Statistics: What White Actually Plays (and Why They Lose)
In over 168,000 games in the Lichess database, White wins 54.1% of the time overall — but that number is inflated by weaker Black play. Let's look at what White actually does at the board. The overwhelming favourite is 5.Bc4+ (128,134 games, 56.6% for White), but Stockfish calls this a mistake that loses about 1.1 pawns of advantage. Next is 5.d4 (15,916 games, 52.0%), the engine's top move. Then 5.Nc3 (9,137 games, 51.2%), 5.Qf3 (5,175 games, only 40.1% for White!), 5.d3 (5,142 games, 37.0%), and 5.e5 (2,303 games, 35.4%). Notice how the scores drop sharply once White steps away from d4 and Nc3 — you have serious winning chances against the weaker moves.
Punish White's Three Most Common Mistakes
If White plays 5.Bc4+ (the most popular move by far), don't block with the king — that's exactly what they want. Simply play 5...d5, giving back the pawn to open lines. After 6.Bxd5+ Nxd5 7.Qh5+ Ke6, your king actually finds safety and you have a crushing attack with two developed knights against White's scattered pieces. This is a classic Stafford trap that wins many games at club level. 5.Qf3 is another mistake — here you can simply play 5...d5 again, threatening the queen and your e4 pawn push. 5.d3 is an inaccuracy; White tries to defend e4, but you can play 5...d5 and you're simply better developed and ready to castle by hand. In each case, the theme is the same: open the centre and trust your activity over White's extra pawn.

Frequently asked questions
Is the Stafford Gambit sound for Black?
In the Nxf7 line specifically, Stockfish evaluates the position at -2.24 after 4...Kxf7 — a near-winning advantage for Black from a theoretical standpoint. However, this comes with a catch: you need to know the precise replies to White's best moves. In practice, White wins 54.1% of games at this position, which means many Black players fail to convert. The opening is very playable at club level but requires study.
What is the best response to 5.Bc4+ in the Stafford Gambit?
Do not block with your king! Play 5...d5, giving back the pawn. After 6.Bxd5+ Nxd5 7.Qh5+ Ke6, your king centralises but is remarkably safe, and your two knights coordinate beautifully against White's scattered army. This is the thematic Stafford refutation and leads to a winning attack.
Why does White win 54% of games if Black is winning?
The -2.24 evaluation assumes perfect play from both sides. In practice, many Black players don't know the key follow-ups and drift into passive positions, allowing White to consolidate the extra pawn and simplify. The Stafford Gambit punishes White's mistakes, but if you play aimlessly, White's material advantage becomes decisive. The drill is designed to teach you the exact plans and moves you need.
Should I play the Stafford Gambit in serious games?
The Stafford is a sharp weapon best suited to rapid and blitz games where White can be caught off guard. Statistically, at 168,891 games, White's win rate is 54.1% — meaning Black scores 43.2% wins, which is excellent for a gambit that sacrifices a piece. If you prepare the key lines (especially against 5.Bc4+ and 5.Qf3), you'll significantly outperform that average.
