This book provides a rock solid opening repertoire for Black, using systems based on the move …c6.
The backbone of this repertoire is the Caro-Kann versus 1 e4 and the Semi-Slav (via a Slav move order) versus 1 d4. In general these systems aim to neutralise White’s early initiative. They aim for success by the gradual accumulation of small advantages, rather than by emerging victorious from an early tactical melee (which is rather problematic with the black pieces at the best of times).
