In planning maneuvers, it should be remembered that the other army will also be maneuvering, leading to a form of ‘dance’. The general who understands the other side’s maneuvers will most likely win.
Good maneuvers include surprise, for example where the enemy thinks you are behind them, then finds you have slipped past them and are in front.
This is the skill of the general.
In business, manuvering is also important, and a surprised competitor is one who is put off their footing. For example when they are enticed to great expenditure for no real gain.
