The superman punch seems to be a powerful technique in Muay Thai. I have had it used on me many times by a guy who likes it. It breaks through my guard frequently from the sheer force and momentum behind it.
1)What are the features that give its value? Is it the fact that the body moves more with it to add extra momentum? Is it that the body is higher up to make counter strikes more difficult? The range from where it begins? Or that the start of the move looks like feigned kick?
2)In which situations do you use it? When the opponent is far away? When there guard is strong? When they are in a defensive mode? When you want to get close quickly? When they look like they want to kick? etc.
3)Given the choice of various punches to throw, eg. cross/jab etc., why choose the superman punch?
