"When I first thought of this book, I planned it purely as a book for amusement - a hundred chess puzzles to solve if you could. This remains its basic idea, and the book can be perfectly well used for this and nothing more. However, when one writes a book it begins to some extent to take charge and I have been unable to prevent other features from creeping in.
Firstly, I have added a fairly long introductory section on the basic elements of tactical play and combinations. Provided you dont expect too much from this, it should be helpful if you are an inexperienced player - it should at least give you some idea of what is going on. And secondly, in the Test Papers I have added a competitive element for those who enjoy testing their skill. Everyone who has worked through the first seven sets of positions with some measure of success should be able at least to have a good shot at the first of the three test sets."
