Comment: Dealing with Trump would be like a goaltender on a penalty shot.  Do not commit based on all the razzle dazzle moves.  Wait for him to really commit first.  Then respond in a stong intelligent but clear and calm way.  As a negotiator he will respect that and you will get your best deal.  Waiting allows you to exploit his weakness,  he will not be patient.  He will always want to move on to the next circus.
