Caro-Kann — Karpov Variation
B17 · Played as black · Intermediate · Caro-Kann
Develop the knight to d7 first so the kingside never gets shattered
The main line
1.e4 c6 2.d4 d5 3.Nc3 dxe4 4.Nxe4 Nd7 5.Ng5 Ngf6 6.Bd3 e6 7.N1f3 Bd6 8.Qe2 h6 9.Ne4 Nxe4
Strategic ideas
- Play …Nd7 before …Ngf6 so a knight trade on f6 can be met with …Nxf6, not …gxf6
- Keep the pawn structure flawless at the cost of a slightly passive setup
- Trade a pair of knights on e4 to ease the position without conceding anything
- Break with …c5 once developed to challenge d4 and free the game
- Learn the 4…Nd7 5.Qe2! trap — 5…Ngf6?? is smothered mate on d6
Key themes
- Solid — Black's structure stays completely intact — there's nothing at all to attack
- Positional — The game is decided by squares and structure, and Black's structure is the sounder one
- Flexible — The d7-knight keeps …c5, …e5 and …Ngf6 all available until White commits
Typical plans
The point of …Nd7 is small and permanent: it means that when White trades a knight on f6, Black recaptures with the other knight instead of the g-pawn, so the kingside is never shattered. Karpov and Smyslov both made careers out of this, and it's the line the Caro-Kann's reputation for indestructibility really rests on. The cost is a tempo and a slightly cramped position, and one trap worth knowing cold: 5.Qe2! Ngf6?? runs into 6.Nd6 mate, with Black's own pieces doing the smothering.
Move by move
- e4 — White claims the centre.
- c6 — Black plays the Caro-Kann, preparing …d5 with pawn support.
- d4 — White builds the ideal centre.
- d5 — Black strikes at e4.
- Nc3 — White defends with the knight.
- dxe4 — Black trades, resolving the centre.
- Nxe4 — White recaptures with the knight, taking a good central square.
- Nd7 — Black develops the knight to d7 first. The whole point: if White ever trades a knight on f6, Black recaptures with this one instead of the g-pawn, and the kingside stays whole.
- Ng5 — White jumps to g5, eyeing f7 and e6. This is also the moment for the trap — 5.Qe2! here would meet …Ngf6 with 6.Nd6 mate.
- Ngf6 — Black develops the second knight, now that it can safely be recaptured on.
- Bd3 — White develops, aiming at h7.
- e6 — Black shores up d5 and f5, and opens the f8-bishop's path.
- N1f3 — White brings the last knight out, supporting the g5-knight and the centre.
- Bd6 — Black develops actively, eyeing the b8–h2 diagonal.
- Qe2 — White lines the queen up on the e-file and clears d1.
- h6 — Black finally kicks the g5-knight, having got everything else out first.
- Ne4 — White retreats to e4 rather than sacrificing on e6 or f7.
- Nxe4 — Black trades knights. The structure is still completely intact, nothing is weak, and Black is a move away from castling — the Caro-Kann's whole argument, made without ever taking a risk.
