Caro-Kann Defense: Masi Variation: what to play after Nf6?

In the Caro-Kann Defense: Masi Variation (ECO B12), White possesses a clear central initiative and scores best by challenging Black's kingside knight immediately. The two principal continuations are the space-gaining advance e5 and the natural developing move Nc3. Both choices secure a distinct advantage, with e5 yielding an engine evaluation of +1.13 and Nc3 evaluated at +1.04.

The Direct Push With e5

The most frequent continuation in the database is e5, chosen in 50.3% of the 393,013 recorded games. This thrust immediately kicks the knight from f6 and seizes space in the center, allowing White to score 58.2% from this position. An illustrative continuation demonstrates White expanding further with tempo: e5 Nd5 c4 Nc7 Nc3 d6.

Developing Naturally With Nc3

The engine's secondary choice, Nc3, appears in 36.2% of recorded games (142K recorded) and delivers a 56.1% score for White. Rather than committing the center immediately, White protects the pawn on e4 and prepares to meet kingside development with a timely strike. The primary engine line continues Nc3 g6 e5 Nd5 Nxd5 cxd5, trading off the centralized knight and maintaining control over the center.

Solid Defenses of the e4-Pawn

White also tests quieter approaches that defend e4 without committing the b1-knight to c3. The bishop development Bd3 features in 9.1% of games with a +0.69 evaluation and leads into lines such as Bd3 d6 c3 e5 Nd2 g6. Alternatively, White plays f3 in 2.8% of games (+0.47) or Nd2 in 1.6% of games (+0.62), each preserving central solidity while steering toward slower, positional battles.
