The critical position to know

After 1.d4 Nf6 2.c4 e5 3.dxe5 Ne4, the position is already sharp and concrete. Stockfish rates this +1.00, a clear, lasting advantage for White. That means you are worse here and need accuracy. The good news is that this is a very playable training position: if you know the right answer and the common mistakes to expect, you can make White work hard for the advantage instead of drifting into trouble.

Best reply and what it asks for

The engine's best move here is Nd2, continuing Nd2 Nxd2 Bxd2 d6. This is the move you should be ready for in the drill. Your practical goal is simple: meet White's idea without panicking, and stay alert for the follow-up that keeps the position coherent. In this opening, knowing the main engine answer matters more than trying to remember a lot of side lines.

What the database says White usually plays

Across 193,330 games at this exact position, White most often chooses Nf3, f3, Nc3, Qd4, Qc2, or e3. The biggest practical clue is that the position is very well played in practice, so you will see familiar ideas over and over. Nf3 is the most common continuation, while f3, Nc3, Qd4, Qc2, and e3 are also frequent tries. That makes this an excellent drill position: you can learn the pattern, then test it repeatedly against an adapting engine.

Mistakes you should be ready to punish

The clearest warning sign is f3, which is a blunder and loses about 3.8 pawns; better was Nd2. Nc3 is an inaccuracy and loses about 0.7 pawns; better was Nd2. Qd4 is also an inaccuracy and loses about 0.9 pawns; better was Nd2. In practical terms, that means you should stay alert for overambitious queen and pawn moves, then rely on your knowledge of the main reply rather than trying to win the game immediately.
