Kata dori menuchi is the logical development from the kata dori grab. The kihon presentation of kata menuchi is for uke to execute two quickly successive actions; the kata grab followed by an immediate overhead strike (shomen uchi). To learn to deliver two discrete attacks in a quick succession requires serious practice.
I have covered katadori menuchi in greater detail in >this< earlier post.
And at close range, the immediacy of uke’s strike will require a muscularly direct response to the kata dori menuchi attack.
Look to Yamada sensei’s presentation of variations (and note how he demonstrates the attack’s efficacity!)
Yamada sensei demonstrates a more direct (omote) response given the close proximity.
[An important note on nage’s timing. Although the kihon presentation is the grab-strike executed by uke, Yamada sensei presents a second explanation. Uke initiates the grab and nage immediately responds with a back hand strike to uke’s face, which uke blocks, resulting in the katadori menuchi encounter.]
Extend the initial maai (range) and the potential for blending increases. A play-list link to Christian Tissier’s presentation.
The immediate blend is predicated upon a specific timing – one established by the distance (maai) that forced uke to a committed advance in order to strike nage.
Of course there are variations – and Tissier sensei demonstrates a close-range flow potential
You need to understand and be able to execute them all!
