    • Paiguru:
    "No Ko" is misleading. Only dead in Japanese ruleset.
    d4rkm4tter:
    There is a direct ko that can be avoided though.

    "Bent four" in the corner is dead – if there are no unremovable ko threats. If there is a seki on the goban then the "Bent four" becomes a simple ko.

    According to the linked page: Bent four in the corner is dead – if there are no unremovable ko threats. This puzzle requires a solution that does not involve ko at all.
    Farkas:
    I disagree with your comment.

    It is not possible to kill the group unconditionally. Only ko or seki. Bent four it is a ko in this case

    Girod:

    d4rkm4tter:
    It's bent four.
