The famous Russian Grandmaster Evgeny Bareev took a real challenge in writing this book: "Say No to Chess Principles!". The author presents his material in a typically humorous style, but not forgetting the players behind the moves. The material is divided into several chapters including ' A Queen Behind Enemy Lines', 'At the Edge of the Board' and 'Killer Delayed Castling'. In his introduction Bareev explains: "However it also happens that chess players often discover significant resources which formally exist outside the typical rules of chess. Those who know how to break all the rules and work around those specific guidelines reach the very top". This book is simply an amazing read discovering an unique tool: break the dogmatic rules when possible!
