"Okay, you plan to lie to one or more of your opponents and need some help. The first question you must ask yourself is why. Why do you need to use a lie? Some players use lies all to often, sometimes without reason, and the result is a player that finds that no one wishes to ally with him and no one trusts him. Even when such a player speaks the truth, other players do not believe him. This is bad. Use lies only when it benefits you and not as a routine diplomacy trick. A good lie depends on the fact that the player who utters the lie has some reputation of telling the truth. If you have a good reason for lying to your opponent, then go ahead to read step 2, but if you do not you might be better off not lying. Believe it or not, honesty usually actually is the best policy."
