Caro-Kann Defense

The Caro-Kann (1.e4 c6) is the French Defense's sober older brother. Black prepares ...d5 just like in the French, but supports it with the c-pawn instead of the e-pawn - which keeps the light-squared bishop free to develop outside the pawn chain. The result is a solid, slightly passive opening that's famously hard to break down. Karpov, Petrosian, and Anand have all used the Caro as a main weapon.

Main line: Classical Caro-Kann

After 2.d4 d5 3.Nc3 dxe4 4.Nxe4 Bf5, Black releases the central tension and gets the c8-bishop to its best square. White plays 5.Ng3 attacking the bishop, and after 5...Bg6 6.h4 h6 7.Nf3 Nd7, Black reaches a classical Caro-Kann setup: solid pawn structure, well-placed bishop, no weaknesses. The price: Black is slightly cramped and slow, so winning chances are limited unless White overextends.

Variations

Advance (3.e5)

White locks the centre and grabs space. The big difference from the French Advance: Black's bishop comes out to f5 before the centre closes - 1.e4 c6 2.d4 d5 3.e5 Bf5. Now Black plays ...e6, ...Nd7, ...Nh6-f7, and ...c5 at the right moment. The Short variation (4.Nf3 e6 5.Be2) is the modern preference for White.

Exchange (3.exd5 cxd5)

Trades happen, but unlike the French Exchange the pawn structure isn't quite symmetric - Black has c-pawn for c-pawn but the centre is half-open. After 4.Bd3 Nc6 5.c3, White sets up a Caro structure with reversed colours, slightly better. Solid, slightly drawish, but Black has clear plans.

Panov-Botvinnik Attack (3.exd5 cxd5 4.c4)

The aggressive cousin of the Exchange. White creates an isolated d-pawn position by force - the same isolated-d-pawn structures you'd get from a Tarrasch or QGA, but with reversed colours. White has active piece play and attacking chances; Black has the structurally better endgame if they survive. The Caro-Kann player's biggest test.

Two Knights (2.Nc3)

White avoids 2.d4 entirely. After 2.Nc3 d5 3.Nf3, the position has many transpositions but Black usually plays ...Bg4 or ...dxe4. Less critical than the main lines but practical for White players who want to dodge Caro-Kann theory.

Common traps

Don't let the bishop on f5 get trapped: after 1.e4 c6 2.d4 d5 3.Nc3 dxe4 4.Nxe4 Bf5 5.Ng3 Bg6, the bishop on g6 is committed. If White plays h4 and Black plays ...h6 (preparing ...Bh7), then a careless next move can run into Nxh6 or other tactics on the kingside dark squares. Be careful about castling kingside too early.

Watch the c-file: in any Caro-Kann line where pawns get traded on c4 or c5, the c-file opens and rooks come fast. Both sides want to contest it - whoever loses the file usually has a passive position.

Typical plans for Black

Black's strategic core is the safe development of every piece to a good square: knights to f6 and d7, bishop to f5 (or g6 after kicked), other bishop to e7, queen often to c7 or a5. Then castle short and play for ...c5 or ...e5 at the right moment. Endgames are usually fine for Black - the pawn structure is healthy and the queenside is solid. Most Caro-Kann wins for Black come from outlasting an over-ambitious White player.
