After 1.d4 Nf6 2.Bg5 e6 3.Nd2 Be7, Black's main idea is simple: break the pin on the f6-knight before White can reinforce it. By developing the bishop to e7, you are ready to kick the g5-bishop with ...h6 or, if White plays e4, to meet it with ...d5 and a solid pawn centre. The position is still fluid — White has not committed to a pawn structure yet. Your task is to complete development without allowing White to build a lasting space advantage. The engine's small edge for White (+0.25) reflects the first-move initiative, not a real threat. In practice, Black scores a healthy 43.8% across 8,852 games, showing this is a fighting, playable line for club players.
The Most Critical Reply: e4
The engine's best move is e4, which has been played in 2,738 games. After e4, the natural follow-up is ...d5, then e5 Nfd7. You get a French-like structure where Black's knight retreats to d7 and the centre is locked. White scores 52.1% from this line — respectable but not overwhelming. The key for Black is not to panic after e4. Your plan is straightforward: ...c5 or ...c6 to challenge White's centre, develop the light-squared bishop to b7 or d7, and castle quickly. The pawn on e5 gives White a space advantage, but it also gives you a fixed target to undermine later.
What the Statistics Reveal
The database of 8,852 games at this exact position tells a clear story. White's most popular move is e3 (3,396 games, scoring 54.3%), which prepares to develop the king's knight and keep the position closed. The engine slightly prefers e4, but e3 is the practical crowd-pleaser. Ngf3 (948 games, 53.7%) and c3 (567 games, 52.7%) are also common, each aiming for slow, solid development. Notice that every move except one scores above 50% for White. The exception is h3 (127 games, 46.5%) — a rare, slightly passive move that actually favours Black. If your opponent plays h3, you have already outplayed them in the opening.
The Mistake to Punish
The biggest blunder White can make in this position is Bxf6. This bishop-for-knight trade has been played in 399 games but scores only 49.6% for White — the lowest of any common move. The engine calls it an inaccuracy, losing about 0.6 pawns of advantage compared to the best move e4. After Bxf6, Black replies ...Bxf6, gaining the bishop pair and freeing the f6-square for other pieces. White's dark-squared bishop was their most active piece, and trading it off for a knight that was already well-defended is a strategic gift. If your opponent plays Bxf6, you can be happy: the evaluation swings toward equality, and you have the more flexible long-term position.
