    Still not resolved.

    I looked into the history. The initial position got changed and then the problem didn't make sense anymore. Here is the original position with one less stone on the outside which makes the opponent block instead of throw in.

    As pointed out by the previous comment, this tsumego has no solution. I do not see any way to fix it, so I recommend just deleting this tsumego.

    After B5-A3-B4 white can throw in at F1 I don't see how black continues after that. And even after white J4 - black F1 white can play the key point at B1 and again wins? Unless I missed something this problem doesn't have a solution.
    posetcay:
    Yes, it is not possible to kill after F1.

    Starting with A17 is not a correct solution, since D19 at A18 dies without ko, I have uploaded the SGF.

    t3 q1 t2 o1 k2/k3. white escapes and black is left with only one eye. Blacks outside shape might need a reinforcement
    Farkas:
    Agree. Corrected and further sequence added.

    a17 d19 threatens a18 b19 and to take on f19 which will end in a ko
    d4rkm4tter:
    Ko is now the best result.

    Problem says “no ko”, but white can force ko by blocking at d19.
