It does matter what stance the opponent uses. It is one of the most significant factors involved in the trick when these demos are performed!Originally Posted by YiQuanOne
Your comment leads me to believe you do not have a clear understanding of the importance of stance or how to exploit your opponent's stance to your own advantage. At least not objectively.
His demonstration is easily repeatable by anyone with the knowledge of biomechanics and a little practice!
You never take a bar bet on the challenger's terms because it is a challenge he has set himself up to win. It is the same for demonstrations. They are designed, by their nature, to succeed in making a point and thus are guaranteed to make the point without argument or challenge by the audience, in most cases.
If you are unable to see the reason Sam can knock the guy back is primarily because of his opponent's weak stance and secondarily because of the way he uses "external" force against a compliant opponent, then you are drinking koolade and not thinking for yourself!
