Stockfish rates this +0.04, a tiny edge for White. That means you are not better in any practical sense; you are basically equal and must keep developing well. The database agrees that this is a battleground where both sides can play for a normal game: across 43,034 games at this exact position, White wins 34.2%, draws 3.4%, and Black wins 62.4%. The message is simple: if you want to make this opening work, you need to treat it as a real opening position, not as a surprise weapon that wins by itself.
The engine’s main answer
The engine’s best move here is Nc6, and the listed continuation is Nc6 Bb5 d5 d3. That tells you the kind of game you should expect: Black develops naturally and aims for active central play, while White needs to keep pieces moving and avoid drifting. In the drill, pay attention to whether you can continue developing without giving Black an easy lead in activity. Your goal is not to force a flashy tactic, but to reach a playable middlegame with your pieces coordinated.
What the database reply choice suggests
The most-played continuation is Nc6, with 15,807 games and White scoring 33.7%. Other common replies are d6, e6, a6, g6, and e5, and White’s results against each of them stay in the same broad range. That is useful for training because it shows the opening does not hinge on one single move. You should be ready to meet several Black setups, but you do not need to memorise a long forcing line to get value from the opening.
How to handle the practical fight
Because the position is close to equal, the main priority for White is to develop smoothly and avoid creating extra weaknesses. The knight on a3 is unusual, so every move should be judged by whether it helps your pieces come out and your king stay safe. When Black chooses one of the common continuations, do not panic: keep the position under control, look for sensible squares for your pieces, and be ready to adapt to Black’s central and kingside ideas. The drill is most useful when you focus on making clean, simple decisions rather than trying to prove the opening is already winning.
