re the last two movements -
pick leg your leg up, place it down (body change), feed hand and wipe arm (shuto)
LOTS going on with these movements,
however as A Bunkai I teach -
against anything high and straight'ish (commited pushe to chest, punch to face) -
from a fence - turn off line, sharpish (thats the leg pick up and place), so attacker enters your reach with attack but doesn't connect as your cover hand deflects,
then use 'sticking' (touch) principle to target a rake/poke to eyes or shuto to neck dependant on your position.
The next elements I introduce are the placement of the leg to disrupt balance, and the pick uphand, not picking up but striking as a stop hit.
These 2 elements up the response significantly.
Hope that makes sense, it is difficult to write about specific Bunkai for me.
I always miss stuff.....and get it in the wrong order............
the timing in the basic kata is eyes, feet, hands obviously this can become variable in application, and it's messy !
