That means you are essentially equal, so the drill is about making the right practical choice and not drifting into an easier game for White.

This opening is not about memorising long lines. It is about handling an unusual first move with confidence and keeping the position active. The database at this exact position shows a very mixed practical picture: White wins 50.8%, draws 3.6%, and Black wins 45.6% across 172,867 games. That is close enough to equal that small decisions matter a lot. If you stay alert and choose the right continuation, you can keep White from getting a comfortable edge.
The engine's main idea
The engine's best move here is bxc5. In the main continuation given, it goes bxc5 e5 c3 Bxc5. That tells you the first practical test: can you handle the capture on c5 and keep the position under control? In this kind of structure, active development and clean piece play are more important than trying to win something immediately.
What White tries most often
The most-played continuation is bxc5, with 100,834 games, and White scores 52.6% there. The other common tries are b5 in 33,045 games, Bb2 in 29,838 games, a3 in 5,450 games, c3 in 1,880 games, and Ba3 in 464 games. That means you should be ready for a small menu of ideas rather than one forced line. If you can answer the most common capture well, you already know the opening better than many opponents.
Moves to watch for
Two moves are flagged as mistakes here: Bb2 and Ba3. Both are inaccuracies, and both lose roughly a pawn compared with the stronger capture bxc5. So if White goes for one of these bishop moves, you should recognise that they have stepped away from the most accurate way to handle the position. Your job is to keep the game simple, active, and stable while White is the one taking the risk.
