“Conceal your dispositions, and your condition will remain secret, which leads to victory;  show your dispositions, and your condition will become patent, which leads to defeat.”

“first lay plans which will ensure victory, and then lead your army to battle;  if you will not begin with stratagem but rely on brute strength alone, victory will no longer be assured”

“do many calculations lead to victory, and few calculations to defeat”

“In making tactical dispositions, the highest pitch you can attain is to conceal them”

“These military devices, leading to victory, must not be divulged beforehand.”

“If you know the enemy and know yourself, your victory will not stand in doubt; if you know Heaven and know Earth, you may make your victory complete.”

“Begin by seizing something which your opponent holds dear; then he will be amenable to your will.”
