Velobici: Why not send an email to Yang Yilun and ask ?

Thad: Seems like a good idea except for two reasons. I hardly know My Yang. if every one who read his book emailed him, he would be flooded with way too many requests to handle.

This way people can just come here and learn the joseki.

Also, I started the problem with the idea that those who wish to make a systematic study of joseki, can come here knowing which to study first.
