This book is part of a new series from Quality Chess examining the cutting
edge of opening theory. The idea is to identify the most important
theoretical battlegrounds and then analyse as deeply as possible in search of
improvements. Thus the reader will be ahead of the current state-of-the-art,
rather than lagging behind trying to memorize old games.

The Cutting Edge 2 considers the Sicilian Najdorf – a favourite opening of
ambitious players at every level. This book concentrates on lines where White
chooses 6.Be3, heading for the English Attack. The variations covered are:
