The primary continuation with Nf3

The move Nf3 is the standard approach for White, aiming to transition into a solid setup.

Central and queenside alternatives

While Nf3 dominates the statistics, other options exist to alter the pawn structure or piece coordination. The move c3 has been played in 8.1% of games (51K recorded) and often leads to the line c3 d5 Nd2 Bd6 Ngf3 O-O, reinforcing the d4 square. Alternatively, Nc3 appears in 5.2% of games, typically resulting in Nc3 d5 exd5 Nxd5 Nf3 Bb4, which leads to more active piece play for both sides.

Strategic objectives for Black
