Therefore, when engaged in combat with an opponent, never be impatient. Do not launch an attack until there’s a distance of one step between you and your enemy, then launch a sudden attack so as to force the enemy to be caught totally unprepared. Launching a sudden attack in this way, one gains the advantage of an extra step towards the enemy, making it extremely difficult for him to react in time, the result normally being a feeble attempt to move half a step to the right or left, or else retreat straight backwards. This makes it very easy to remain in contact with the enemy, maintaining control of the situation by affecting the enemy’s balance and positioning. You therefore avoid giving him the chance to attack first and take away his opportunity to manage the situation...
