    gasana:
    Is the 'wrong' line starting with kosumi not ko? Depending of the rules, could be better solution for the attacker no?
    d4rkm4tter:
    The default rule set on the website is Japanese. Superko is alive or the game ends with a tie. A Ko would be better if the player was way ahead in points and/or threats, but in general alive in Superko would be best. Let's add a hint.

    Sadaharu:
    Not really black to kill since white can live in Eternal Life?
    jhubert:
    Eternal life possibility is presented as the solution but it is indeed dependent on the superko rule. Changed to "black to play" anyway.
