This is a sharp opening where Black immediately challenges your centre with ...c5, and you push d4-d5 to grab space. Black then attacks the d5-pawn with ...Nf6. Your knight on c3 defends it, and now Black has to decide what to do. The engine's best move for Black is d6, reinforcing the centre and preparing ...exd5. The key struggle revolves around the d5-pawn: if Black captures it early, you get a comfortable game, but if Black delays, you may need to defend accurately. Across 158,423 games at this exact position, White scores 54.3% wins – a solid result, but Black's 42.6% win rate shows there's real counterplay to handle.
The Engine's Recommendation and the Best Reply
The top engine move for Black here is d6 (22,512 games in the database). After 4...d6, the engine continues with 5.Nf3 exd5 6.exd5. This line keeps White's centre solid and maintains the space advantage. The stats show it's not the easiest path for you, though – White scores only 48.8% after 4...d6, meaning equality is a realistic target, and you'll need to play actively. The most common move by a huge margin is 4...exd5 (60,512 games), but the engine calls that a mistake – it loses about 1.4 pawns of advantage. So if your opponent snaps off the pawn early, you're already in a good spot.
The Most Popular Replies and Your Score
Here are the main moves Black plays, ranked by frequency, along with White's winning percentage in each case. Pay attention to which ones are actually mistakes or inaccuracies (according to the engine), and which ones give you the best results in practice. - 4...exd5 — 60,512 games. White scores 54.7%. Engine says: mistake (loses ~1.4 pawns). The early capture lets you develop freely. - 4...d6 — 22,512 games. White scores 48.8%. Engine says: best move. This is the toughest test. - 4...Qa5 — 20,778 games. White scores 53.4%. Engine says: inaccuracy (loses ~0.9 pawns). - 4...a6 — 12,676 games. White scores 53.8%. Engine says: inaccuracy (loses ~0.9 pawns). - 4...Be7 — 8,423 games. White scores 57.5%. - 4...b6 — 7,020 games. White scores 58.2%. A couple of these (exd5, Qa5, a6) are objectively worse for Black, but in practice they still score okay because club players need to know how to punish them.
Mistakes You Can Punish
Three common Black replies are flagged by the engine as suboptimal. If your opponent plays them, you should be ready to press your advantage. - 4...exd5 is a mistake (loses about 1.4 pawns). Black grabs the pawn too early. Your plan: recapture with the e-pawn (5.exd5) and develop naturally, keeping your space advantage and pressure. The stats back this up – you win 54.7% of these games. - 4...Qa5 is an inaccuracy (loses about 0.9 pawns). Black puts the queen out early, inviting you to gain time. - 4...a6 is also an inaccuracy (loses about 0.9 pawns). A waiting move that doesn't address the centre. In both cases, the engine wants Black to play 4...d6 instead. Your job is to recognise these suboptimal moves and build your position with solid developing moves rather than chasing a quick knockout.
