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.

ambitious players at every level. This book concentrates on lines where White

chooses 6.Be3, heading for the English Attack. The variations covered are:
