Re: What is an "advanced technique?"
Well the dogma statement that I always liked was that there are no secrets in Shodokan Aikido - everything is there from the first day on the mat. Took me awhile to see it all, and appreciate it, but it was true. I suspect that they are not unique in this respect.
Still it is very easy to be trite and say its all in the basics. For sure complicated techniques are not necessarily advanced but neither are the majority of basic techniques. Far more interesting is which techniques we consider advanced and why? What do they contain that non-advanced techniques don't.
