Stockfish rates this -0.66, a small edge for Black. That means you are slightly worse here, so this is not an opening where you can relax and expect an automatic attack to appear. The position is still playable, but you need to be precise with development and follow-up moves. If you treat it like a normal aggressive start without care for your king, Black can take over the initiative quickly.
Black’s most important reply
The engine’s best move is Nc6, and that is also by far the most common continuation in practice. Across 67,273 games at this exact position, Nc6 appeared in 45,158 games, so this is the reply you are most likely to face in the drill and in real play. The main message is simple: expect Black to develop naturally and hit the centre rather than grabbing space for no reason.
What the game scores show
The database numbers suggest that White is not winning this position by force, but the position is far from hopeless. Across 67,273 games, White wins 47.5%, draws 2.8%, and Black wins 49.7%. Those results are close enough to tell you that this opening is playable, but also close enough to warn you that small mistakes matter a lot. If you want to get value from the gambit, you need to know the best plans, not just the opening move order.
The replies you should recognise
After the key position, Black has several main continuations, and the most frequent ones all lead to a familiar type of struggle. Nc6 is the main reply, while e6, d6, d5, g6, and e5 also appear often. The practical lesson is that you should be ready to meet solid development moves and not assume Black must respond in one forced way. In the drill, focus on staying active, completing development, and keeping your king safe while Black chooses from these common setups.
The moves to punish
Some replies are already flagged as mistakes or inaccuracies. d6 is a mistake, losing about 1.0 pawns, and the better move was Nc6. g6 is an inaccuracy, losing about 0.8 pawns, and the better move was Nc6. e5 is also an inaccuracy, losing about 0.6 pawns, with Nc6 again the better move. These are exactly the kinds of moves you want to learn to recognise in the drill, because they tell you when Black has stepped away from the most accurate development.

What is Black’s best move after 1.e4 c5 2.d4 cxd4 3.f4?

Which replies are most common against this gambit?
