Petrov's Defense: Stafford Gambit as Black
The Stafford Gambit in the Petrov's Defense is a sharp test of nerves for Black. After the opening moves, the position is already tense and the engine says White is much better, so this is not a carefree gambit. Your job in the drill is simple: stay accurate, know the engine's best reply, and punish the most common deviations. Play the position against the engine and learn what Black can realistically aim for when White is ready to grab the advantage.

Stockfish rates this +1.51, a near-winning advantage for White. That means you are clearly worse here and need exact play just to keep the game going. The database backs up the warning: across 7,046,171 games at this exact position, White scores 45.6%, draws 3.2%, and Black scores 51.2%. In other words, Black does win games here, but the position is still dangerous and you should treat every move as a test of accuracy.
The move the engine trusts
The engine's best move here is Nxc6. That continuation leads into Nxc6 bxc6 Nc3 Bb4, which is the shape you should recognise in the drill. The point is not to hope for a miracle, but to choose the move that keeps your position as workable as possible. If you are playing Black, this is the key line to know before you start looking for anything else.
What White usually chooses
The most-played continuation is Nxc6, with 5,861,938 games and White scoring 44.6%. Other common tries are Nf3, d4, Nxf7, Bc4, and Nc4. The fact that these moves appear so often tells you what your opponents are trying to do: keep the pressure, simplify into a better endgame, or grab material and attack. In the drill, stay alert for these choices and compare them with the engine's preferred answer.
The mistakes to punish or avoid
Three continuations are marked as mistakes in this position: Nf3, d4, and Nxf7. Nf3 loses about 1.5 pawns, d4 loses about 1.3 pawns, and Nxf7 loses about 2.2 pawns, with Nxc6 given as the better move in each case. For Black, this is useful in two ways: if White chooses one of these moves, you know the position is drifting in your favour; if you are choosing your own reply, you should not drift away from the strongest continuation when the engine already points you to Nxc6.
