First post - apologies if this is a dumb question. I did have a look for previous on the topic in case I could find out without asking! We work a shitoryu version of Annan with our higher grades. I'm a little dubious about any bunkai due to the fact its a very recent kata and had very few ideas about a section one of the guys was asking about. After the kick/palm strike kiai sequence that goes side to side, the version we learned has turn to the front, with a single finger double arm outer block, then chamber right hand to hip, step forward elbow, chop, back fist. Then repeat to the back. The question was, what is the purpose of the finger? Its not used to stab, it becomes a chop then fist on the strikes... What am I missing?
