Caro-Kann Defense: Advance Variation

About this variation

White plays 3. e5 to gain space. Black usually develops the bishop to f5 before playing ...e6, and later strikes at the center with ...c5.

The Advance Variation is 1. e4 c6 2. d4 d5 3. e5. White takes space at once, and unlike in the French, Black can develop the light-squared bishop before closing the center: 3...Bf5 4. Nf3 e6 is the main line. Black then plans ...c5, ...Nc6, ...Qb6 and sometimes ...Ne7-g6, attacking the d4 and e5 pawns.

White has several systems. The Short Variation with Nf3, Be2 and O-O is solid and positional, aiming to keep the space advantage with c3 and a slow build-up. The aggressive approach uses Nc3, g4 and h4, chasing the bishop on f5 and gaining space on the kingside; the Van der Wiel Attack, 4. Nc3 e6 5. g4 Bg6 6. Nge2, is the sharpest version, and the Bayonet Attack, 4. g4, chases the bishop at once. The Tal Variation, 4. h4, also tries to harass the bishop before Black can finish development.

Black's play is based on the pawn breaks. ...c5 attacks the base of White's chain on d4, and ...f6 attacks its head on e5, opening lines for the pieces. If White over-extends on the kingside, Black's pieces can find squares on f5 and d5 and the advanced pawns become targets. The main danger is a lack of space: if Black never achieves a break, the position can become passive.

The Advance Variation is the most common reply to the Caro-Kann in master games, so anyone playing the defense should prepare it well. White players who enjoy space and attacking chances find it a natural choice.

Club players with Black should learn the main ideas against the aggressive g4 lines first, since those are the most dangerous over the board. Knowing where the bishop goes when it is attacked, and when ...h5 or ...c5 is needed, prevents most early disasters. The quieter Short Variation can be learned later through its typical plans.

It is one of the main lines of the Caro-Kann Defense.
