JKD & BJJ Routes

I worked late yesterday so I only caught the end of BJJ. We were finishing our tournament preparations by drilling and doing rounds. After practice Jack talked about not having one way to pass the guard but many routes. As he put it the mistake your opponent makes dictates the pass (of course this means I must make a ton of mistakes wrestling with Jack =D). Jack credits this observation to Rickson Gracie.
Too often we insist on one method achieving something. But the method is dictated by our environment and situation. While a game plan and technique are important, they a adaptable. A plan is a proposed set of future events but must be flexible enough to adapt to the parameters of the now. Technique have general, universal properties and requirements but everyone makes adjustments for themselves and their opponent ideally finding the most successful way among many routes.
