After the moves 1.g4 d5 2.h3 e5 3.Bg2 c6, Black is not just equalising — the engine says the position is already good for you. Stockfish rates this -0.82, a clear advantage for Black. That means you should feel confident about the opening: your central presence is strong, and White has to prove that the extra pawn pushes on the kingside amount to anything concrete.
What the engine wants here
The engine’s best move is e4. The listed continuation is e4 h5 gxh5 dxe4, which shows the basic idea: open lines, keep White uncomfortable, and use the centre while White’s kingside pawns have already moved. You do not need a long memorised trap to do well here. You need to understand that Black’s counterplay is direct and active, not passive.
What White usually tries

This tells you that White often tries to keep the game flexible or challenge the centre right away. Your job is to respond with the same central energy the opening calls for.
