Fine points

Sometimes rules seem to contradict themselves.
Such as Rule #5: "A lead is a suggestion, not a command." A Favorite of mine. I quote it all the time.
Followed by Rule 6: "I am confident; I am decisive. I will not make a mushy lead/follow."
You have to really know what you're doing to realize if you are leading too hard. Sometimes leaders are so pleased to know even approximately what they are supposed to do that they make their moves too strong.
