Lieberman, D.J., (1998) Never Be Lied to Again: How to Get the Truth In 5 Minutes Or Less In Any Conversation Or Situation. St. Martin's Press.

You can learn a great deal on deception and lies in this book. There has been many books that talk about body language of a liar and this book also includes this material as a matter of principle. However, what makes this book stand out is that it looks at confession and lies as a game of words. Dr. Lieberman, a psychologist, provides a great number of tips on what to say to get the right reaction.

Usually, just a few words said in the right way can lead you to get what you want. For example: “I hate to do this but you leave me no choice …” or better “You know what I can do, and I'll do it. If you don't want to tell me now, don't. I'll just do what I have to do…” If he focuses a lot to know what you want to do, then he is probably guilty.

As another example, if someone explains a situation and you respond with “and …”, it is as if you are demanding a conclusion. It feels as if you are not convinced and you expect more information. Saying a simple word will get you a lot more information than you would have imagined otherwise.

There are many examples such as these in the book. These are directly applicable to playing Risk. In fact, the tips are still useful even if you play online. Knowing what to type in the chatbox is critical these days. There are numerous examples of bullying taking place online. If you know what to say and when to say it (or type it for that matter) you will have an edge over others. You will know how not get angry, and simultaneously know how to wind someone up. After all, an angry person will make irrational decisions which may lead him to defeat! Exactly what you want in a game.
