Yep, that's one. How 'bout attack and control whatever is closest using a quick point of leverage on the way in?I'll translate it as, "When you punch me, I'll hit your punching arm." But I have never seen any JKD guy does that.
Or using receptivity and speed, making first strike while an opponent was just beginning a movement.
Lee added lots of things as time went on, but his primary concept was intercepting a movement even BEFORE a typical block or full extension.
