There is a strategic science to sparring. From the outside, sparring looks like random kicks and punches thrown mercilessly with the objective being to injure. From the inside, however, a sparring match is like a chess game. For example, one could not win a game of chess by mindlessly moving around the pieces anymore than one could win a sparring match by mindlessly throwing techniques. Strategy is prerequisite to chess as well as to sparring.
What is strategy?
Strategy goes beyond "What kick should I throw now?" and it answers the question "How can I manipulate the situation to give me the advantage over my opponent?" This strategy comes in two main forms: Overall strategy (macro strategy) and exchange strategy (micro strategy).
