My copy arrived today. I have only had time to read about a dozen entries, but if the whole book is like what I have read, it is going to be the most useful skills book I own. It not only gives a clear explanation of the skills, but also tells when and where they are most applicable, the situations where they will not work well, plus additional information to help you get the most benefit from the techniques as well as what what will detract from their effectiveness. Looks like it is going to be a great resource!
