If your enemy is superior, evade him
The good fighter is able to secure himself against defeat, but cannot make certain of defeating the enemy.
Attack like the Fire and be still as the Mountain
Know thy self, know thy enemy. A thousand battles, a thousand victories.
Birds rising in flight is a sign that the enemy is lying in ambush; when the wild animals are startled and flee he is trying to take you unaware.
Peace proposals unaccompanied by a sworn covenant indicate a plot.
