By playing 2...e6 and 3...d5, you have challenged White's Trompowsky setup head-on. Unlike some offbeat lines where Black accepts a cramped position, here you claim a share of the centre with your pawn on d5. Your light-squared bishop is temporarily blocked, but your pawn structure is flexible, and you are ready to develop naturally. The key task in this position is to handle whatever plan White chooses — whether they develop their kingside pieces, pin your knight further, or try to open the centre with an early c4. Stockfish rates the position +0.25, a small edge for your opponent. That means you are slightly worse out of the opening, but the advantage is modest and the game remains very much alive.
The Engine's Top Choice: Meet c4 Head-On
The engine's best move for White here is c4, immediately challenging the centre. The intended continuation runs c4 dxc4 Nc3 Be7. White aims to recapture on c4 with a piece, building a lead in development and central control. As Black, your response is straightforward: take the pawn on c4, then develop your king's bishop to e7. This line represents a principled battle for the centre, and the resulting positions are well-known and playable for Black. The statistical record supports this — across 18,053 games where White played c4, White scored only 49.8%, which is essentially even. So while the engine slightly prefers White's plan, practical results show you have every chance to equalise.
What the Statistics Tell Us
Across 200,048 games played from this exact position, the overall results are remarkably balanced: White wins 49.8%, draws 4.0%, and Black wins 46.2%. That 4% draw rate is worth noting — this opening tends to produce decisive, fighting games rather than quiet draws. Among the most popular moves White can choose, only Bd3 (56,388 games, 52.5% for White) gives White a noticeably better score. Other common moves like Nf3 (42,234 games, 49.5%), c4 (18,053 games, 49.8%), and c3 (13,866 games, 50.2%) all yield near-parity results. The data suggests that unless White knows exactly where to put their bishop, you as Black are doing just fine.
One Mistake to Watch For
The database identifies Bb5+ as a known inaccuracy for White in this position. While this check might look annoying — it forces you to decide how to block — the engine says it loses about half a pawn in evaluation (with c4 being the better choice White missed). Across 20,746 games where White played Bb5+, White scored only 46.1%, which is actually below average for White here. If your opponent plays Bb5+, you can be satisfied that they have wandered off the most testing path. Your best reply is to block the check with your bishop (Bd7) or knight (Nbd7), developing a piece and remaining solid. This is a small but useful piece of information to keep in your back pocket.
