If we wish to fight, the enemy can be forced to an engagement even though he be sheltered behind a high rampart and a deep ditch. All we need do is attack some other place that he will be obliged to relieve.
Sun TzuWhen the position is such that neither side will gain by making the first move, it is called temporising ground.
Sun TzuTherefore a victorious army first wins and then seeks battle; a defeated army first battles and then seeks victory.
Sun Tzu
