Decap ingredient: power generation.
This is a monkey punch. taught to me by monkey apex the monkey punch is a punch that can be thrown from off a single grab.In its base form the generation is from the combined contraction of the wrist elbow and pecs and can be done with no ground control after a turn over for example. though will probably result in self dq. ideally you want to be pushing off with a hip and a contacted glute. see example.1
Example 2 is a shortened version for a decap
to aim you use your lumbar and shoulders.
failing that just jam a grab hand into their throat then ungrab to pop the head off. sometimes.
