    Djab:
    I think there is a more simple combination that works and is claimed "incorrect" : Q19 R19 S18 S19 R18 P19 T19 S19 N19
    d4rkm4tter:
    Your move has been added.

    After Q19 R19 S18 S19, simply capturing the 4 stones and letting S18 stone be captured is incorrect. Does this mean there is a better solution ?
    d4rkm4tter:
    In Gokyo Shumyo IV, some problems have incomplete solutions right now. There was only one correct move but I found 4 correct moves.

    At the end of the sequence, taking away the last liberties of the black l-shape, it classifies P1 in stead off O1 as incorrect. However i think that any sequence winning the liberty race is good.
    Neri:
    O1 is better because R2 ko treat is smaller in this case.
