Queen's Pawn Game: Accelerated London System: what to play after e6?

In the Queen's Pawn Game: Accelerated London System, White's top engine choice is Nf3, evaluated at +0.02. Developing the knight to f3 controls central squares and preserves flexibility before committing the central pawns. Alternative setups such as Nd2 or solidifying the center with e3 also maintain approximate equality.

Strategic development with Nf3

The move Nf3 supports White's dark-squared bishop on f4 and readies the kingside for castling. By placing the knight on f3, White maintains control over e5 while delaying pawn commitments in the center. An illustrative continuation shows both sides developing naturally: Nf3 c5 e3 Nf6 Nbd2 Qb6. White can also prioritize the queenside knight with Nd2 (+0.02), which can be followed by Nd2 c5 e3 Nc6 Ngf3 Nf6.

System setups and pawn structures

White often uses classical London structures characterized by c3 (+0.01) or e3 (+0.00). After c3, play may proceed c3 Bd6 e3 Nf6 Nf3 O-O, reinforcing the d4-pawn and establishing a solid pyramid. Choosing e3 immediately yields balanced play, seen in the continuation e3 Nf6 Nf3 c5 Nbd2 Qb6. The quiet waiting move a3 is also playable, holding an evaluation of -0.04 in the line a3 c5 e3 Qb6 b3 Nf6.
