Query: Very Basic, Not Much Material

From what I understand this book was "ghost written" - with Fischer doing little more than checking it over and putting is name on it.It contains very simple checkmate problems and no real "instuction". The diagrams take up a lot of space so there is not a lot of material there. A book like Winning Chess Tactics for Juniors for more problems, or Chess For Juniors for real lessons are far far better books.
