You did not quite read my post well enough.
WC players like to use Chain Punching but they also use Horizontal fists as well. They are not stuck..... only to use vertical fists. They also use the basic CMA punching I laid out above. If this guy was a WC player and he used a horizontal fist.... does not mean he is not using WC.

What I forgot to mention is that the CMA punch that fires from the Guard postion can be vertical or Horizontal and still use the skeletel structure if the elbow is still down and the back foot is driving etc etc. So in essence... WC players use this basic punch just like every other CMA. Why do they only get to use a vertical punch?

ps bawang, you forgot to add they need to do some squats before they learn punching techniques!
