Your are not reading carefully my posts. Additionally, first you were talking about gentle kick, now suddenly we can see fast escalation to "experienced kicker" at close range. I suppose in your next post you will talk about facing top MMA artists in formula K1 or UFC? hahahahahah
You simply don't understand what square kamae means and when is used for. I'm not your teacher, so I'll not lecture you how should you practice.
However, have you ever asked yourself why judo folks use such kamae and not million others from Koryu? Well, me, I ask myself such strange questions. What I did notice, that such kamae is very useful when I want to throw someone who is not cooperating with me. Then I continued to analyze why other postures are not allowing me to do it so easily. In conclusion, all these going down to a simple biomechanics of human body.
I need a proper alignment of my body to enter to the attack and I need completely other alignment of my body in the moment of throwing. As every kamae has his strong and weak points, I have to be able to switch kamae to replace, if necessary, weak point initial kamae by strong point other kamae, on the fly!
These are only high level pointers (we are searching here to define problem, responses for question WHAT?), I'll not enter here into details (that would be discussion on realization, so responses for question HOW).
Rather than say that I do not read posts carefully,I would suggest you do not fully appreciate my warped sense of humour.When I mentioned a gentle kick to the leg I was making a vain attempt at humour.You apparently did not see the joke.
Now you state I do not understand square posture.I would turn this around and suggest you are not quite familiar why aikidoka use hamni.Then again I also dont know you /or your teacher.
Now as far as Judo posture is concerned please dont try and tell my granny how to suck eggs[I hope this saying is known to you].
Prior to me taking up Aikido I was a young Judoka. In this capacity I met and trained with world class judoka.I will not bore you listing them since in most cases they are either long since retired or are dead.So I think I am fairly conversant with Judo footwork/posture.Rather than ask your self the questions why not try Judo?You will then understand the differences/sameness.
As you say each posture has its good points and bad.If you get results using or adapting certain footwork , wonderful.
I also had a little chuckle when you suggested my next comment would be about facing MMa /K1 fighters.
Unless they have a division in MMA related to guys aged 70+
I think I will give this aspect a miss.Hope you are well.
