Query: Good intro.

The book provides a good intro for beginners. The best part is the description of the Tae guk forms, although it's essentially limited to the sequence of movements. It won't help you if you know the forms and aim to improve your performance. The remainder of the book, covering basic techniques and basic sparring moves, is simply too basic to be useful. The book briefly describes how to do a basic move, but never discusses the many things you can do wrong. Conclusion: no use beyond the green belt.
