    Added a stone at M2 and black can kill without ko now.
    caranthir:
    Thanks, that's a better problem now for this level I think.

    Answer says "No ko" but white can hane at F19 anytime to try to make a ko
    caranthir:
    Yeah, that's a difficult call. I took the hint away for now.

    The combination A16 - B18 A17 - A18 C19 is marked as incorrect. But I can't find any follow up which succeeds in defending the group in the corner. My answer is each time F19 or C18. I am wrong?
