Caro-Kann Defense: what should White play?

In this position arising from the Caro-Kann Defense, White's most effective and popular continuation is Ng5, which targets the advanced black pawn on e4 while avoiding passive retreat squares. Occurring in 44.0% of recorded games (850K recorded), Ng5 yields an engine evaluation of -0.72 and a 48.4% score for White. Moving the knight forward maintains active piece play and immediately puts pressure on Black to defend the advanced pawn.

The Dynamics of Ng5

Advancing with Ng5 is the principal try to contest the center. According to the engine analysis, play can continue Ng5 Bf5 g4 Bg6 Nc3 Nf6, where White aggressively pushes on the kingside to dislodge the defending bishop while reinforcing the attack against e4. This approach keeps White active, avoiding the cramped positions that result from moving backwards.

The Alternative Central Post: Ne5

The main alternative is Ne5, chosen in 30.5% of games (588K recorded). While the engine evaluates this move slightly lower at -0.96, White achieves a comparable score of 48.6%. An illustrative continuation runs Ne5 Nd7 Bf4 Nxe5 Bxe5 Bf5, where White accepts piece trades on e5 to establish an active central bishop.

Passive Retreats and Disadvantages

Retreating the knight generally concedes greater control to Black. White chooses Nfd2 in 22.5% of games (434K recorded), but the evaluation drops significantly to -1.76, scoring 44.4% following lines such as Nfd2 Qxd4 Nc3 e3 fxe3 Qxe3+. Farther down the spectrum, Ng1 appears in 2.6% of games (-1.77 evaluation, 43.5% score) with Ng1 Nf6 Nc3 Bf5 f3 e6, while the marginal sideline Nh4 is played in just 0.4% of encounters (-2.71 evaluation, 34.5% score), demonstrating that forward central knight moves are strongly preferable.
