We suggest you turn to the Tao Teh Ching:
69 Strategists have a saying: "I prefer to be able to move, rather than be in a fixed position Prefer to retreat a foot rather than advancing an inch." This is called progress without advancing; Preparing without showing off; Smashing where there is no defense; Taking him without a fight. There is no greater danger than under-estimating your opponent. If I under-estimate my opponent I will lose that which is most dear. Therefore When opponents clash The one who is sorry about it will be the winner. -- tr. C. Muller
