When I first got this book I put it to one side as I thought it looked like stuff I already knew from other authors, however, once I got round to reading it and playing through the games I was struck by how clearly the author expressed himself (probably this is well translated as well as sometimes Soviet chessbooks get translated into rather quirky, albeit engaging, English)
There are about a Dozen games played and annotated by the author against top Soviet players like Tal, Keres and Geller at the back of the book and for me they are amongst the best annotated games I have ever seen - lots of clear explanation of ideas and as much variations as required rather than overloading us with computer analysis) They remind of the sort of analysis Timman gives in "Art of Analysis"
In the theoretical part amongst other things there is a very good explanation of Isolated Queen Pawn positions which explained them to me better than previous books on the subject. A lot of examples from Botvinnik's games as one might expect from the date of original publication. Especialy good if interested in the Nimzo Indian.
