An ancient general's short rules for winning any contest - the finest win needs no fight at all.
Chapter 1 ('Laying Plans') says the general who makes many calculations before the battle wins it. Most outcomes are settled in this honest audit, before anyone moves.
When able to attack, seem unable; when near, seem far (Ch. 1). Fights are decided as much by what the other side wrongly believes as by force.
His ranked order (Ch. 3): balk the enemy's plans first, then prevent his alliances from joining, then fight his army. Besieging a walled city is the worst policy of all.
The full line (Ch. 3) is harder than the famous half: know only one side and your chances are even; know neither 'and you will succumb in every battle.'
Securing yourself lies in your own hands; the chance to win is provided by the enemy (Ch. 4). The victorious strategist seeks battle only after the victory is already won.
Water shapes its course by the ground and rushes to the low places (Ch. 6). Just as water retains no constant shape, in warfare there are no constant conditions.

Download the free PDFThe Art of War is a short ancient Chinese treatise on war: thirteen brief chapters of numbered sayings, traditionally attributed to Sun Wu ('Master Sun,' Sun Tzu), a general said to have served the king of Wu in China some 2,500 years ago. Scholars still debate the man and the date - the traditional placing is the late Spring and Autumn period, roughly the 5th century BCE, and some argue the text took shape later, during the Warring States period. Its standing is not debated: for about 1,500 years it stood at the head of China's Seven Military Classics, and generals, founders, and negotiators still read it.
It opens with calculation. War, says Chapter 1, is 'a matter of life and death, a road either to safety or to ruin,' so before any move the general weighs five constant factors - the Moral Law (a purpose ruler and people share), Heaven (seasons, weather, time), Earth (distances and terrain), the Commander, and Method and discipline - and compares his own side against the enemy's, point by point. Most of the famous lines that follow serve that one habit: an honest audit, done in advance.
