Another tip that Chief Justice Roberts shares with Bryan Garner is a great method to prepare for questions from a judge who is not as familiar with the legal area as you are.  His Honor states that you should be able to tell a lay person in five minutes, or less, what the case is about and why you should win.  If the lay person cannot understand what the case is about or does not see why you should win in that time, his Honor suggests that you need to rethink the argument again.
