始記篇 NO.6：

兵者，詭道也。

故能而示之不能，用而示之不用，近而示之遠，遠而示之近。

利而誘之，亂而取之，實而備之，強而避之，怒而撓之，卑而驕之，佚而勞之，親而離之，攻其無備，出其不意。

此兵家之勝，不可先傳也。

這句啥意思：

用兵作戰，就是詭詐。

因此，有能力而裝做沒有能力，實際上要攻打而裝做不攻打，欲攻打近處卻裝做攻打遠處，攻打遠處卻裝做攻打近處。

對方貪利就用利益誘惑他，對方混亂就趁機攻取他，對方強大就要防備他，對方暴躁易怒就可以撩撥他怒而失去理智，對方自卑而謹慎就使他驕傲自大，對方體力充沛就使其勞累，對方內部親密團結就挑撥離間，要攻打對方沒有防備的地方，在對方沒有料到的時機發動進攻。

這些都是軍事家克敵制勝的訣竅，不可先傳泄于人也。

英文這么說：

All warfare is based on deception.

Hence, when able to attack, we must seem unable;when using our forces, we must seem inactive; when we are near, we must make the enemy believe we are far away;when far away, we must make him believe we are near.

Hold out baits to entice the enemy. Feign disorder,and crush him. If he is secure at all points, be prepared for him.If he is in superior strength, evade him. If your opponent is of choleric temper, seek to irritate him. Pretend to be weak, that he may grow arrogant. If he is taking his ease, give him no rest.If his forces are united, separate them. Attack him where he is unprepared, appear where you are not expected.
These military devices, leading to victory,must not be divulged beforehand.
