Caro-Kann Defense: main lines, plans and traps

The Caro-Kann is a solid, reliable defense to 1.e4. Black prepares ...d5 with the c-pawn, so the light-squared bishop can develop actively before ...e6, avoiding the French Defense’s “bad bishop.”

Starts with: 1.e4 c6 2.d4 d5 · ECO: B10–B19

Main variations

Classical Variation

White gains kingside space with h4–h5; Black keeps the bishop with ...h6 and ...Bh7. Stockfish: about +0.4, a normal opening edge.

Advance Variation

White grabs space with 3.e5; Black develops the bishop outside the chain before ...e6, then hits the center with ...c5.

Plans for Black

Trap to know: smothered mate on d6

5...Ngf6?? 6.Nd6# (checkmate)

In the ...Nd7 line, White’s 5.Qe2 sets a famous trap: 5...Ngf6?? allows 6.Nd6, smothered mate, because the e7 pawn is pinned to the king by the queen on e2.
