Wait by the river long enough and the body of your enemy will float by you.

Weigh the situation, then move.

Weak leadership can wreck the soundest strategy; forceful execution of even a poor plan can often bring victory.

If we do not wish to fight, we can prevent the enemy from engaging us even though the lines of our encampment be merely traced out on the ground. All we need to do is to throw something odd and unaccountable in his way.

If your opponent is of choleric temper, seek to irritate him. Pretend to be weak, that he may grow arrogant.

Carefully compare the opposing army with your own, so that you may know where strength is superabundant and where it is deficient.

If you know both yourself and your enemy, you can win a hundred battles without a single loss.
