To sandwich or not to sandwich, that is the question.
There's another thread discussing one punch knockout power wherein Tau and Lee Richardson briefly discuss the elbow strike in Heian/Pinan Yondan. Specifically whether or not the head should be cradled, i.e. sandwiched, when the elbow is delivered. Discussing whether or not one method improves 'brain shake', increasing knockout potential, or not. Lee, I believe, talks about passing the head from hand to elbow, suggesting that there's no cradling when the head is impacted.
The kata, at least within the mainstream styles, seems pretty clear in that it shows the elbow delivered strongly into the palm of the opposite hand. Suggesting of course that the opponent's head is in between. That's the 'standard' application I've been taught by various instructors over the years.
Having tried this method on bags it never seemed to generate enough power for me. I assumed that was becaue the bag was a LOT thicker than the human head. In recent years I bought a BOB style bag, so have been able to practice this on a replica of a human head. Again, not as much power as I would like.
Whereas, Mick Coup makes a very persuasive case here
for the opposite. For using the lead hand to fend off, preventing an opponent from getting inside your guard and also actively not cradling the head in order to deliver maximum brain shake. Personally I like Mick's approach and it pays dividends for apparent power when utilised on a BOB bag.
What do you guys think?
