The move 2...Nc6 keeps the game flexible and supports your e5 pawn. Your main job now is simple: stay sound, finish development, and answer White's central and kingside ideas without drifting into passivity. White has several natural choices here, so this is not a forcing line where one memorised trick solves everything. Instead, you want to understand the familiar setup and be ready to meet the most common continuations with confidence.
The engine's main recommendation
Stockfish rates this +0.29, a small edge for White. That means you are slightly worse here. The engine's best move here is Bb5, continuing Bb5 a6 Ba4 Nf6. That is a useful guide for the drill: White's most principled route is often to ask questions of your knight and make you commit. As Black, you should expect that kind of pressure and stay calm while completing your development.
What the database shows
This exact position has been reached in 335,122,427 games in the Lichess database, so the opening is extremely well tested. White wins 51.0%, draws 4.1%, and Black wins 45.0%. Those numbers fit the engine verdict: White scores a little better, but Black still gets plenty of practical games. The position is not a disaster, but it does demand accurate replies if you want to keep the game under control.
The reply to know and the mistake to avoid
Among the most-played continuations, Bc4 is the biggest one, followed by Bb5, d4, Nc3, c3, and d3. The named mistake in this position is c3, which is an inaccuracy and loses about 0.7 pawns; better was Bb5. That makes c3 a good warning sign for your drill: if White plays more slowly than the main lines, you should still punish it by meeting the position with active, natural development and by knowing that Bb5 is the stronger choice in this position.
How to handle the most popular continuations
White's biggest choices are Bc4 and Bb5, so you should expect an open game with normal development rather than immediate chaos. Against these moves, the practical lesson is to stay alert to bishop activity and keep your pieces coordinated. If White chooses d4, Nc3, c3, or d3 instead, the same strategic idea applies: do not chase ghosts, and do not waste tempi. Your best results come from steady development, king safety, and meeting White's central ambitions without creating weaknesses of your own.
