Dismantling the Sicilian (New and Updated Edition)

I read this book when I was 15, and it helped me build a complete repertorie in the Open Sicilian. A lot of the variations were easy to follow, in part, because they were very consistent (basically, the Be3 + Qd2 setup against almost anything).

I'm sure theory has evolved a lot in the past 20 years, so the fact there's an updated version of the book is a relief.

I think this is a good resource to learn both theory and some of the ideas as well.
