Showing a player a rule.........

Let it go unless they bring it up. The last thing you want to do is make it look like you are holding a grudge from the week before. The other option if they don't bring it up is to show them after their game is over. You also want to word in such a way as you just want them to know why you called it the way you did. Like you said you don't want to give the impression that you are bettter than they are or I told you so.
