    F19 leads to ko, marked it as wrong and added refutations. Also added a stronger resistance to E17.
    d4rkm4tter:
    Oh wow, F19 G19 is ko. I spent too much time on this problem 5 years ago.

    Upper left corner Black to move: F19 - H18 - C17 - F18 - G19 - E17 - H19 - G16 - J19 After this move white looks dead for me. E19 and G18 are miai. Am i missing anything?
    caranthir:
    Thanks for your comment. Considering your sequence, you are right. Therefore, H19 should be answered by J19 instead of G16. Updated sequences.

    One of the accepted solutions, rightmost in the tree, results only in a ko; see SGF for rrefutations.

    e19 f17 f19 h18 b19 works too. And f19 h18 should be wrong. f19 h18 f18 f17 c17 e17 b18 and white is dead. f19 h18 f18 e17 f17 g16 g18 and black captures white. Instead white should play f19 g19 which should lead to ko.

    You had some mistakes in your coordinates but I think I got it.

    I second Tashel's solution. At the end of the variation white has miai to falsify one of the two eyes.
    Farkas:
    N4 was a mistake in the sequence. Corrected.

    wO1>bM2>wR3>>bO2>wN1>bP3>wM1>bN4>wL1 kills, yet it is marked as being incorrect
    Neri:
    White have 2 eyes after your sequence.

    I can't see why P3-O3-O1 doesn't work.
