Where I am really disappointed by the shape it is more than in the background, there are a lot of errors in the book. I assume they are due to translation. Confusion between black / white, lined paragraphs as a result. . . Diagrams are incomplete, and I do not mean those that have been refined to facilitate the reader's understanding, but diagrams which one or more major plays have been omitted!
Makes you wonder if someone really dintéressé reread the book. For my part, first disappointment of the collection "for Dummies". Not being an expert on the chess literature, I have no other reference to propose for a more serious equivalent.
