In the book I set out a repertoire for Black against all the systems where White doesn’t go in for an open Sicilian – the Rossolimo the GP Attack, the Closed Siclian the Morra Gambit … and so on.

This is basically the book form of my Chessable course – which has had a very favourable reaction – but I’ve tweaked some of the variations, added a couple of new chapters and model games and written proper introductions and conclusions for each chapter that will help you navigate through the variations.
And quite simply many prefer a book to the digital format.
