I've tried to cover it yesterday with some great help from the folks of the KTL, do you think it's reasonable?
It seems that either of these (a or b) works (With an exactly identical following)
hnishy: Panda Sensei says a is the only move to win. Against White b, Black c, White d and Black e leads to ko.
The need for an extra move against the eye here loses the semeai
W seems to live easily like this
B will get either a or b here and it's either lack of liberties for W or a big eye and a lost semeai
If W takes a or b B will take c (Obviously W can't take c else B will take d)
I'll either expand on it later or hopefully somebody else will? ;)
