A Guide to Chess Improvement: The Best Of Novice Nook
By Dan Heisman. The content of this book is extracted from Heisman's "Novice Nook" columns on (the now apparently defunct) ChessCafe.com. In addition to chapters on opening play, tactics, endgame, positional chess and strategy, the book provides advice and guidelines on topics relevant to the concrete, non-theoretic (if you will), aspects of playing rated, over-the-board play at chess clubs and tournaments - for example, Time Management, Thought Process, Skills and Psychology. It's like having a chess coach by your side. For many instructive articles by Heisman treating all aspects of the game of chess, see his "Novice Nook" articles in the ChessCafe.com archives....
