Caro-Kann: Two Knights, 3...dxe4 4.Nxe4: what should White play?

In the Caro-Kann Defense Two Knights variation after 3...dxe4 4.Nxe4, the primary continuation for White is Ng3. This retreat attacks the active bishop on f5 with tempo while vacating central squares for development. Engine analysis evaluates Ng3 at +0.48, making it the most successful and standard try, selected in 63.6% of over 2.02 million recorded games with a 58.3% score for White.

The strategic role of Ng3

By choosing Ng3, White forces Black to decide the placement of the light-squared bishop immediately. Relocating the knight to the kingside maintains flexible piece coordination and leaves the d-pawn unblocked to support future central control. An illustrative continuation demonstrates this positional approach with Ng3 Bg4 c3 Nf6 d4 Bxf3, where White secures central space with d4 while Black concedes the bishop pair.

Alternatives in the Two Knights

White occasionally selects alternatives that sidestep the immediate knight retreat, though none match the statistical profile of the main line. The retreat Nc3 appears in 12.9% of recorded games (scoring 48.5%, eval +0.04), often resolving into balanced structures such as Nc3 e6 d4 Nd7 Bd3 Bxd3. Solid positional setups include d3 (9.8% popularity, 45.0% score, eval +0.17), continuing d3 Nd7 Qe2 e6 g3 Ngf6, and the bishop challenge Bd3 (8.9% popularity, 47.7% score, eval +0.25), which often leads into Bd3 e6 O-O Nf6 Re1 Nbd7. A rarer tactical option is Qe2 (4.7% frequency, 51.7% score, eval +0.20), leading to lines like Qe2 e6 g3 Be7 c3 Nd7. Despite these playable options, Ng3 remains the theoretical benchmark.
