This book is excellent for Club Players with a rating below 2200. The strength of the book is its combinative mixture of grand master games along with high level club matches by the authors. The inclusion of many of the authors games allow for a step by step in depth understanding of certain variations. In addition it is especially useful for those club players who tend to favour attacking through h4 on their ninth or tenth moves. The reason for not giving a five star rating is due to a lack of examples where the attack is conducted through f4 rather than h4.
