Train this openingAbout this opening
You hold the center and Black is about to challenge it. d5 is the most played reply here and it is essentially forced if Black wants the opening to make sense, since the pawn on c6 was played precisely to support it. What matters now is which structure you choose. Advancing e5 gains space but frees Black's light-squared bishop to reach f5, which is the one piece the Caro-Kann exists to activate. Trading on d5 leads to quieter symmetrical play. Defending with Nc3 keeps the tension and is the most flexible, and the alternatives to d5 all score badly for Black.
Plans
- Advance e5 for space, but expect the bishop to reach f5.
- Defend with Nc3 and keep every option open.
- Trade on d5 for a symmetrical structure and slow play.
- Take the f5 square away before the bishop gets there.
Where the pieces belong
- Pawn: e5, gaining space if you accept the bishop coming out
- Knight: c3, holding the center and keeping tension
- Bishop: d3, contesting the diagonal the bishop wants
- Knight: f3, covering d4 and e5
- Pawn: c3, supporting d4 against the coming c5
Space against structure. You have more room, Black has no weaknesses, and the game turns on whether the light-squared bishop finds a good square or stays passive.
