    There is a branch with 15 moves said incorrect but white is living with 2 eyes. The correct one can arrive to the same result with white living also with 2 points.
    caranthir:
    If I understood correctly, I guess the policy is to disqualify the 2 point solutions because they are that much worse in points? Or is it so that the correct one would also branch, depending on the opponent's responses, to a 2 point solution? I'm confused because the only 15+ move branches that I see lead to the 5 point solution. Could you link a relevant position?

    Thank you posetcay for the work! It looks good. Just this end branch is alive [current position] Maybe just that one branch should be also green?
    posetcay:
    Thanks for pointing it out, opponent response was wrong. Added correct refutation.

    Took me a lot of time but I finally managed to fix this problem by deleting the solution tree and creating it from scratch. I really hope the solution is correct this time...

    the solution on the site contains errors. In sequence C18, C19, C17, E18, B13, B12, C13 next correct move is A17! instead of specified A13 and after A14, D16, A16, B15, B19 - we have ko only. But sequence C18, C19, C17, E18, B13, B12, C12 is correct, because next A13, A15, A17, B11, C13, A14, B10, B15, B13, A12, B13, D16, B12, B14 (or C13), C13, A11. [current position] + B14 C13 A11.

    This task is looking bad. It is better be sent to the sandbox.

    S7 also lives. The sgf refutation at R2 does not work. It is answered by S8. For example: S7 R2 S8 T3 S9 with life.

    [current position] This refutation branch is also wrong, because both R7 and S6 bring the group alive.

    [current position] yes, this is wrong, but the next move on S10 is the wrong refutation. I assume it should be on T14 and just a ko
