Caro-Kann Defense
Preparing ...d5 with the c-pawn instead of the e-pawn is the Caro-Kann idea. After 1...c6 and 2...d5 Black contests e4 at once, and if White trades on d5, Black takes back with a pawn and keeps a pawn in the center. The light-squared bishop stays free to come out to f5 or g4 before Black plays ...e6.

Key moves
1. e4 c6
- 1... c6A modest pawn move with a clear job: support ...d5 next turn. It also opens the d8 to a5 diagonal for Black's queen. The small cost is that the queenside knight cannot use c6, so it usually develops to d7 instead.
What separates it from the French
The French also hits e4 with ...d5, but its 1...e6 shuts the c8 bishop behind the e-pawn. In the Caro-Kann that bishop has open diagonals. Black often develops it to f5 or g4 first and only then plays ...e6, so the pawn chain no longer locks a piece inside.
Where White goes after 2.d4 d5
3.e5 is the Advance Variation, which grabs space and fixes the center. 3.exd5 cxd5 is the Exchange Variation, which can turn into the Panov Attack with c4. 3.Nc3 or 3.Nd2 lets Black take on e4 and leads to lines like the Classical with ...Bf5. 3.f3 props up e4 with a pawn.
White can also skip d4. After 2.Nc3 d5 3.Nf3, the Two Knights Attack keeps both knights out and leaves the d-pawn's role open.

Questions
Is the Caro-Kann passive?
It starts quietly, but Black challenges the center on move two. Most lines give Black a firm pawn on d5 or a clean development plan, and the play gets sharp when White picks lines like the Advance with an early g4.
Where does Black's queenside knight go?
With a pawn on c6, the b8 knight usually heads for d7, where it backs up ...e5 or ...c5 breaks and can reach f6 or b6 later.
