Tactics. Tactics are the ability to use your weapons effectively and efficiently in actual combat to counter your opponent’s attacks and defenses. It is also the knowledge of what weapons to use in certain situations. Your tactics are determined by your available weapons and ability to use them. You need to determine some things about your opponent so you may plan your tactics, such things as, is your opponent an aggressive attacker or a counter fighter, a brawler or technician, seeking a quick defeat or a long drawn-out fight, or trying to hurt you or just humiliate you?
Intuition. Intuition is the ability to predict your opponent’s actions, based upon his or her physical cues, such as shoulder or hip movement or eye contact.
Luck. Luck is when something with a low probability of happening, happens. What determines whether it is "good luck" or "bad luck" is the level of preparedness. Remember, chance favors the prepared mind.
