"In summary, this book is a major piece of work by Richard Palliser and Simon Williams that adds considerable material to the increasingly popular Botvinnik English. In a sense the Botvinnik English is a kind of very grown-up London System and Colle Opening approach to playing with the White pieces (i.e. a system approach) and a welcome addition to White’s armoury. Anyone wishing to take it up will find this book to be a reliable and friendly companion." John Upham, British Chess News.
