Caro can

The Caro-Kann Defence, 1 e4 c6, has always appealed to me. It has the advantage of staking a claim in the centre by means of … d5, without the disadvantages of the Centre Counter (1 e4 d5) which brings out Black’s queen prematurely, or the French Defence (1 e4 e6 2 d4 d5), which locks in the black queen’s bishop. A new book by Jovanka Houska, Opening Repertoire: The Caro-Kann (Everyman), details Black’s strategies against the dangerous Advance Variation, while in the main line she recommends the early development of Black’s queen’s bishop, as in the following game.

(diagram 2) 15 … Bxc2 This seems almost desperate, but in fact I was no longer very worried; White’s c-pawn was a useful unit and its loss causes problems. My main fear was that Tal would find a way to sac on e6 and explode my position before I could get castled.
