Fighting the indeterminable

When picturing the ultimate fighter I see a man completely unconfined. His movements are such that its imposiible to determine his intent. You dont know whether or not he is stepping or preparing to kick. You cant tell if hes ready to grab or strike or to takle you. His angles and movements make it impossible to determine where the attacks are coming from.He appears weak but obviously he is not after he takes great advantage of you. He is undeniable yet undeterminable. Knowing nothing how could you defend? This is what JKD is all about being that guy.
