TherapieGo: After the sequence E16, D15, F17, what happens if Black plays F16? I have the feeling that this problem is more complex than it seems. I think that even if someone finds a solution for Black's F16, this possibility should absolutely be added, as it will be very instructive. I'm adding an SGF file with only the branches I've explored and checked with the AI!
AaronP: After black B19 in the correct variation, white responding at D19 seems like a trickier resistance than C19.
D19, C19, A18, A16, A17, A19, B17, B14
