When a combatant chooses to fight intelligently, the best method is to yield to the superior force and overcome it by its own momentum. By doing so, the one who acts first creates the momentum for their own destruction. To do this requires intelligence, understanding the adversary, and your own strengths and limitations.
Every serious engagement with others should be treated as if you are in battle. Negotiate, propose, further an agenda of good by always considering the stance of others, understanding their needs, and working to achieve what is the best for the people you serve. Whether the individual you face is in a truly adversarial role with you is immaterial. Combatants win because they consider the positions of the enemy they are about to engage, respect their positions, and work to use those positions to leverage the best advantage.
