A judicial defence is like a game of chess or poker: psychology matters too. After all, the judge evaluates evidence on the basis of inner conviction. His behaviour in the process may be influenced by his caseload, the region in which he works, his character, his previous employment and even his age. This can be useful for a representative to consider when preparing a position on a case. Some even prepare different versions of the pleadings and choose from them on the spot depending on the behaviour of the judge. Experts believe that a professional representative should feel the judge's mood and adjust to it.
