Mike You mentioned this.
When we strike we should attack the skeleton, and we must go through the target, not to it. We must also control the hinges of the body (pivot points) and always cancel the back up weapons. We need to take away their dimensions while maintaining our own - height, width, depth creating time (the fourth dimension).
Expert horsemanship, control the horse with proper ques and neck reining to control the head and spine of animal.
As you are saying conroling the pivot points or hinge of body movement. Kosho calls those "the keys".
The spine is what you want to control in body movement, skelton also, breaking it really does a number on someone.
Strike's can damage skelton, (as Cung Le did with Frank Shamrock, foot to forearm) breaking a bone in face, arm, wrist, is not that difficult to be honest. Done it many times, was with assistance of a baton.
If you learn the correct hand position with proper alignment it helps. Boxer punch is not good for breaking items. Most will end up breaking the small finger area and bone in hand. See it all the time in boxing, even with wrapped hands.
Most who practice the art do not toughen the hands, knuckles, as did the Okinawans.
Chow practiced hitting the sand at the beach, various hardness for hours. Vernon Kam, he was very good at breaking blocks, gave many demos. He learned from Chow, that is how he did it also.
Okinawan Kempo was and still, teachs that whole senario. First book by EPS, Kenpo Karate, Law of the fist and empty hand, explains it. Good stuff.
Deflecting with a check or strike/block, to gain a better position is what I try to do, force with force is tough on both as a rule. It is about movement, not being there, allowing opponet to be out of balance and take advantage of it. Deliver the proper strike at the proper time.
Most don't have the kind of strength of GM Pick or Mas Oyama
I think your post was very good.
