For the intercept fighter, take away the reach advantage.
When faced with an enemy too powerful to engage directly you must first weaken him by undermining his foundation and attacking his source of power.
Japan's famous swordsman Miyamoto Musashi calls this strategy "injuring the corners," and advises that "When you cannot risk coming in close to your opponent because of his strength or reach, then attack what is within your reach." The idea is to attack the attacker's hands, arms, or legs and wear the opponent down through multiple injuries. Use hard blocks that cause enough pain to cause your opponent to reconsider attacks.
For the jam and block fighter, use feints. While blocking feints, he will be left open to attack.
Create an expectation in the enemy's mind through the use of a feint. If you plan to attack on the right flank, maneuver your left. Where the enemy expects you to attack he will reinforce. When he does so half his army or more is thus neutralized defending nothing. Then with your full strength you attack his remaining forces.
