The two foreknuckle punch is anatomically incorrect anyway...
I am curious for your reasoning. I believe it is the anatomically correct way because it is the most unforced alignment of the wrist hand and arm bones.
I just have one question based on some of the earlier discussion on punching and kihon I picked these questions based on Ives posts.
If Kihon is supposed to be the perfection of technique and also by popular theory a place from where to start creating muscle memory why differ some critical aspects so greatly?
Please elaborate on "some" critical aspects.
And again why the ''gap in kihon and kumite'' if you have someone do Kihon for 6-12 maybe even more months without any sparring and all that time he is keeping his guard low, core ''soft'', heels on the ground or whatever else travesties and then suddenly he starts doing Kumite and hears that this was a ''gap'' then what the hell was the point of it all?
That's exactly one of the reasons people start asking these questions about punching methods.
The method of punching in karate (primarily the straight punch) - and maybe also the method of kicking (front kick) - is an unnatural movement to the human body and mind. That's why you create these techniques first on the level of cognition. Here the route and the logic behind it come in to play.
Training Kihon develope techniques that are relatively independent of other body parts, or stance. A preferred kamae in kumite comes to mind.
The use of a guard in kihon training isn't necessary because it serves a different purpose.
If Kihon is training to reach a ''perfect technique'' (something we will never reach as such a thing would go against the essence of Martial Arts and well common sense) then how can there be any gap in practical fundementals in Kihon and Kumite?
I speak of an ideal technique for the purpose of creation. Perfect techniques aren't defined. What is neaded is an efficient technique, that is essential to karate in my opinion.
The reason why there is a gap between practical fundamentals in kihon in realtion to kumite is actually quite simple. Kumite is dynamic because all opponents are given the options of initiative for action or reaction. Kihon is essentially an individual excercise.
That's why yakusoku-kumite and it's levels of learning for different purposes, maai, chakugan, unsoku etc. is necessary.
Back to the guard; there isn't any reason for that in karate, since you have to be able to launch an attack or recieve from any position and most importantly the reasons mentioned.
Most of the times in a budo situation* there is no time for it. Next to that is telegraphs intentions, thus possibly taking away initiative.
*(By a budo situation I mean one of a life or death encounter.)
