The Symmetrical systems of the English Opening constitute a large and important area of modern chess opening theory. The strategic variety to be found within this book is staggering: from the sedate Symmetrical Variation to the wild gambit lines of the Anti-Benoni, and almost everything in between!

This book provides detailed coverage of the theory of all lines stemming from 1 c4 c5. It includes many variations that often arise from different openings entirely, such as the Semi-Tarrasch, or when White avoids a Benko or Benoni. A particular highlight is the discussion of the Hedgehog, which a popular workhorse for many tournament players, as it enables Black to play for a win without taking undue risks. Throughout the book, though, Hansen shows that in many lines regarded by a lot of players as boring or uninteresting, there is plenty of scope to liven the game up, if one is familiar with the subtleties.
