Caro-Kann Defense: Classical Variation

The Classical Variation of the Caro-Kann Defense (1.e4 c6 2.d4 d5 3.Nd2 dxe4 4.Nxe4 Bf5, or with 3.Nc3) is the most common way of handling the Caro-Kann. It is also called the Capablanca Variation after the Cuban world champion José Raúl Capablanca, and it was long considered to represent best play for both sides.

The idea

Black brings the light-squared bishop out to f5 before playing ...e6, makes very few compromises in the pawn structure, and later plays ...c5 to contest the d4-square. Much of the Caro-Kann's reputation as a solid defence comes from this variation. White chases the bishop with Ng3 and the h-pawn.

Main lines

• 5.Ng3 Bg6 6.h4, the Main Line. The usual continuation is 6...h6 7.Nf3 Nd7 8.h5 Bh7 9.Bd3 Bxd3 10.Qxd3 (8.h5 is the Spassky Variation in this database). The pawn on h5 looks ready to attack, but it can prove to be a weakness in an endgame.
• 5.Ng3 Bg6 6.f4, the Maróczy Attack, and 6.Nh3, the Flohr Variation, are less common.

Lines in which Black castles queenside gave the Caro-Kann its reputation of being solid but somewhat boring. More popular recently are lines with Black castling kingside or even leaving the king in the centre, which can be sharp and dynamic. When the players castle on opposite sides, White has attacking chances, as the brilliancy Milman–Fang, Foxwoods Open 2005, showed.

Strengths and weaknesses

Strengths

• A sound pawn structure with very few compromises.
• Black's light-squared bishop is developed before ...e6 locks it in.
• It is frequently used by top-level players.

Weaknesses

• White gains kingside space with h4–h5 in the main line.
• The lines with queenside castling are solid but have a reputation for being somewhat boring.

Who should play it

The Classical Caro-Kann suits Black players who want a solid, healthy position and are ready to choose between quieter and sharper castling plans.
