Do the unexpected. As the 16th century Japanese sword master Musashi once wrote, "If the enemy expects fire, give him rain." Most combinations attack high-low-high-low or vice versa. Opponents tend to expect this rhythm. Take advantage of this expectation and change the rhythm.
Never directly attack a well entrenched opponent. Instead lure him away from his stronghold and separate him from his source of strength.
When an counter attacker stays well guarded and waits for your attack, you are foolish to attack directly. An opponent always exposes a target when attacking and an observant counter fighter can hit that target before the attacker is within position to do damage. This defensive strategy is difficult to penetrate, so one must entice the opponent into action by showing a obvious weakness in your false attack. Then, when you launch your true attack, you know where the counter attacker is going to strike.
Encourage your enemy to expend his energy in futile quests while you conserve your strength. When he is exhausted and confused, you attack with energy and purpose.
