As previous reviewers have said before, the book is fantastic.
Unfortunately it has a peculiarity that makes it somewhat hard to read. The author wants to do without any indicators (!, !!, ?, !?, etc), which says have been abused in the past.
Well, the author takes that premise to the extreme, removing all indicators, including the capture and check symbols. For example, Nxc3+, Nxc3, Nc3 and Nxc3# are written as Nc3 on this book. It may not sound as a big deal, but it eventually gets tiresome. It is specially annoying when side-lines are given.
Here is to hoping the next revision is printed on Algebraic or Descriptive notation.
