"The art of war is like a game of chess, but with real lives."

"The general who wins a battle makes many calculations in his temple before the battle is fought. The general who loses a battle makes but few calculations beforehand."

"In war, the way is to avoid what is strong and to strike at what is weak."

"Do not repeat the tactics which have gained you one victory, but let your methods be regulated by the infinite variety of circumstances."

"The clever combatant imposes his will on the enemy, but does not allow the enemy's will to be imposed on him."
