Ensure physical (power), breath, and mental (kiai) focus with each attack to instill fear in the opponent by showing a commitment “to kill with one blow.” Since there is no formal warm up before competition, this also ensures that adrenalin be released for power and endurance.
Know opponent's style
Do your homework. Know your opponent’s style, strengths, favorite techniques, and weaknesses. Your strategy should be to become proficient in all areas so you will be prepared to act instinctively to the opponent’s favorite techniques. Your size compared to the opponent will be an important factor in your choice of offensive and defensive actions.
If hand techniques to the head are not permitted, aim for the front of the shoulders since the center of the chest is usually well guarded.
