With 4.Bd3, you've developed another piece and kept the centre tense. Black's central pawn on d5 is under pressure from your e4-pawn and the knight on c3. The key battle is about the d5-square: Black would love to trade pawns and relieve the tension, but you want to recapture with a piece (ideally the knight) to maintain an active position. Your light-squared bishop, often a problem in French structures, is already outside the pawn chain — a real asset. The engine's +0.79 evaluation confirms you have a lasting edge that's easy to build on, as long as you avoid unnecessary complications.
The Engine's Preferred Path
Stockfish recommends dxe4 as Black's best reply, leading to dxe4 Nxe4 Qxd4 Nf3. After these moves, Black has swapped the central pawns and offered a queen trade. You don't have to accept, but notice that Black's queen comes out early and becomes a target. Your knight on f3 will gain a tempo by attacking her, and you'll have smooth development ahead. Only 12,800 games in the database reach this line — many opponents avoid the exchange, but if they do play dxe4, you can handle it confidently with natural moves.
Meeting the Most Popular Replies
Black plays Bb4 most often (38,221 games). Your scores are 55.6% here — excellent. This move pins your knight against the king, so you'll need to decide whether to unpin with Bd2 or try something like Nge2. Either way, stay calm: the pin isn't fatal, and you have a space advantage to work with. The next most common is Nf6 (17,253 games, you score 53.8%). If Black attacks your e4-pawn, you can defend it with Nf3 or consider e5, pushing the knight away. Both lines keep your edge intact.
The Mistake to Punish
Among the known inaccuracies in this position, Ne7 stands out. It's played in 6,822 games and your scoring is 52.7% — decent, but the engine says it loses roughly 0.7 pawns compared to the correct dxe4. Why is Ne7 a mistake? It blocks Black's own bishop on f8 and does nothing to challenge your centre. The knight would be better on f6 attacking e4, or staying put. When you face Ne7, look to seize the centre with e5 or maintain the tension — Black's passive setup gives you time to build a serious attack. Punish the inaccuracy by keeping the pressure up.

Frequently asked questions
Is 4.Bd3 the best move against the French Paulsen?
4.Bd3 is a strong, natural move that scores very well in practice — White wins 54.6% of games from this position. While other moves like 4.e5 or 4.Nf3 are also playable, 4.Bd3 develops a piece, prepares kingside castling, and keeps the tension in the centre. The engine gives it a +0.79 evaluation, confirming a clear advantage for White.
What should I do if Black plays dxe4 in the Paulsen Variation?
If Black plays dxe4, the engine's best line continues dxe4 Nxe4 Qxd4 Nf3. You recapture with your knight on e4 and then develop your knight to f3, gaining a tempo by attacking Black's queen on d4. This leads to active piece play while Black's queen has to move again. You emerge from the opening with a lead in development.
Why is Ne7 a mistake in this French Defense line?
Ne7 is considered an inaccuracy because it loses roughly 0.7 pawns compared to the better move dxe4. The knight on e7 blocks Black's light-squared bishop from developing and does nothing to challenge your central pawns. Meanwhile, you can continue developing and prepare a central advance with e5 or maintain the tension. It's a passive move that gives you a free tempo.
