Used Rapid Chess Improvement:

Rapid Chess Improvement is the ideal book for serious adult players who want to improve. It describes a study plan which came about thanks to a re-evaluation of standard chess teaching and includes several unique components aimed at improving deficiencies in the play of adult players. This book is the only one of its kind for the simple reason that it has been written by an author who hugely improved his own rating over a 12 month period by following his own advice. He therefore fully understands the challenges faced by enthusiastic players who are relatively new to the game. This is in sharp contrast to most books aimed at this level which are usually written by very strong players who have long forgotten what it feels like to be starting out in the game.
