SGF

TherapieGo:
After B18, C17, C18 doesn't work because instead of D18 the opponent can play F18 and now you can only get ko. So I suggest removing the D18 branch completely. I've also completely reworked the SGF today, so I must have worked on it for at least 4 hours. I've mostly added non-existent sequences. I can't make an exhaustive list of everything I've done, so here is the SGF file, but if someone want to check it would be extremely complicated considering the time it takes. So in the end I guess you'll either have to trust me or not. Be sure that I've really done my best and it's only for good faith.

E18, D18, B18, B17, A18, F18, G18, E19 and now only A16 is correct, not C18.
