It is sufficient to estimate the enemy situation correctly and to concentrate your strength to capture him. There is no more to it than this. He who lacks foresight and underestimates his enemy will surely be captured by him.
Sun TzuTo persuade your enemy to (retreat) before the fight is to defeat them even before the battle begins. An enemy made ally is no longer an enemy.
Sun TzuThere are roads which must not be followed, armies which must not be attacked, towns which must not be besieged, positions which must not be contested, commands of the sovereign which must not be obeyed.
