I recently read Secret Notes by Bronstein and Voronkov (Edition Olms, 2007) and thoroughly enjoyed it. There is a lot of personal reminiscence as well as 30 annotated games.

As for Sorcerer's Apprentice, it is a bag of jewels. The later (New In Chess, 2009) edition has a lot of additional material apparently. I found it good for dipping into - I probably wouldn't read it from beginning to end, as I did with Secret Notes (almost in one sitting).

I am thinking about buying this book as i am a huge fan of david bronstein. There are two versions of the book available the original or an updated version. What is the difference?
Would you recommend the book ?
