Query: Heisman Looks at the Process of Chess Improvement

This is a great book for chess parents and teachers, particularly those who are teaching youngsters. The author discusses several topics that I have not seen anywhere else. These topics are about how people learn chess and the levels of chess knowledge rather than they are about technical aspects of the game.The concepts presented include chess vision, thoroughly knowing the rules, playing according to principles that suit the situation, and the etiquette of chess play. The author shows how to build chess vision by using "chess mazes", but I would really have liked to see more of these. The other concepts are illustrated with concrete examples from the author's experience as a chess teacher.I would highly recommend this book to an improving adult or the parent of a young chess player.
