To a surrounded enemy, you must leave a way of escape.

When your opponent gives you an opening, be swift as a hare.

Thus those skilled in war subdue the enemy's army without battle .... They conquer by strategy.

Throw your soldiers into positions whence there is no escape, and they will prefer death to flight. If they will face death, there is nothing they may not achieve.

Build your opponent a golden bridge to retreat across.

What enables the wise sovereign and the good general to strike and conquer, and achieve things beyond the reach of ordinary men, is foreknowledge.

The Art of War is self-explanatory
