For anyone who learnt it from their JKD teacher, Please explain how "chi sao without touching" is done. From my understanding it's about using tactics such as the ability to manipulate the opponent's reactions so that you can anticipate exactly where he will move next or what his next move will be, that way you will always be in control of his timing, distance and rhythm because you caused it to occur during the pre-contact phase. What I am trying to figure out is what are some of the tactics used to carry this strategy out.
