    Sadaharu:
    Yeah white can answer D19 with B18. Seems like will end up in a double ko and white is still alive.
    posetcay:
    B18 is a very cool move, added it as a refutation to D19 and changed correct answer to B18 as first move (and removed the continuation after E19 because it is unnecessary).

    Repost: I don't think the answer is correct. After C19 C18 D19 white can answer at B19. There are other ways to answer C19 too.
    d4rkm4tter:
    It seems D19 first is correct but I'm not sure. If there is a refutation, B18 would be correct.

    Why was my comment made to no answer needed?
    posetcay:
    I gave it a thumbs up, don't know why it looks like no answer needed.
