Very simple technique. The guy plugs his gym pretty hard, but it’s worth it to check out the two techniques.
The strategy is really simple: if you are in the initiative and striking to the head, a common response from the opponent is to cover up. Keeping your rhythm, you either pull away or push away half of the cover. Pulling away is attractive to me, because it merges will with southern mantis boxing: you get contact and you get the lateral angle. And you get to continue to aggressively strike.
I wish the video quality was higher though.
