Re: Shomenuchi nikkyo
You folks might want to experiment with the matching aspect of the feet when doing Ikkyo, Nikkyo, Sankyo, Yonkyo, and Koshinage when doing them fluidly. First, try Ikkyo with feet mirror image in level of direction as you cut down. Then try too far forward and not in far enough. Then try Nikkyo at each of these levels of entry. Then try Sankyo. Then try Yonkyo at all those levels of entry, then too close and too far away from Uke for Ikkyo. Then try Koshinage at all those variations.
You will find that Ikkyo works best when perfectly matched in level of entry and distance. Then you will find that Nikkyo works best when not entered enough, Sankyo when entered too far, Yonkyo when too far apart from Uke, and Koshinage when too close to Uke.
Of course, this doesn't apply when doing these techniques step by step, only when doing it fluidly in Ken style. It also helps if Nage is the one doing the Shomen Uchi.
Hey, it's hard to explain with words. Just try experimenting with matching of distance of entry, and distance from Uke. You'll find out for yourself. Depending on your style of doing these techniques it may or may not apply to your Waza.
BTW, Nikkyo, Koryu style works very well at speed for a jab to the face.
