This opening is a flexible Modern setup with an early ...c5, so you are trying to challenge White’s centre instead of sitting back. The position is not automatically equal, though. Stockfish rates this +0.62, a small edge for White. That means you are slightly worse and need accurate play. In practical terms, you should expect White to keep pressure in the centre and choose a move that decides whether the game becomes more tactical or more positional.
The engine’s main reply
The engine’s best move here is dxc5. The listed continuation is dxc5 Bxc3+ bxc3 Qa5, which shows the kind of imbalance this opening can create very quickly. For Black, the lesson is not to panic if White opens the centre first — but you do need to know the tactical follow-up and stay alert for piece activity and queenside pressure. This is exactly the sort of moment where the drill is useful: one precise choice can steer the whole middlegame.
What White usually chooses
The most-played continuations are Nf3 (31,542 games, White scores 48.4%), dxc5 (26,066 games, White scores 50.8%), d5 (25,414 games, White scores 48.1%), Be3 (24,934 games, White scores 50.6%), e5 (7,721 games, White scores 39.1%), and Nge2 (1,483 games, White scores 50.6%). That spread tells you White has several natural ways to continue, so you should not prepare for only one plan. Focus on sound development, pressure on the centre, and fast piece coordination rather than trying to memorise a single narrow line.
The moves you must respect
The clearest warning in the data is e5. It is a mistake here and loses about 2.3 pawns; the better move was Be3. Nge2 is also marked as an inaccuracy and loses about 0.6 pawns; again, Be3 was better. For your study, that means these are the kind of over-ambitious or passive choices you want to punish when they appear. If White pushes too early or develops less efficiently, you can often gain time and improve your pieces.
