    Collin Hodges:
    Answer says "Alive. Opponent can create seki by playing D19." D19 is not a consistent answer, depending on which corner of the board is being displayed. For me, D19 is irrelevant. Thank you.

    Resolved.

    Adding to what others have said, it seems like adding "(Seki)" would keep this problem set consistent. Problem 8/200 is nearly identical but says "(Seki)". So the logic there would apply here and vice versa
    caranthir:
    I changed the problem so that F1 is the final move, and there's a notification about a possibility of seki.

    I agree that "(seki)" should be added to the title. I was confused, not seeing a solution, until I saw the comments.

    On other problems in this series it has said "Black to live (seki)". So I assumed there must be a solution beyond seki which there is not.
    caranthir:
    Well, the seki in this case is contingent, because it's gote to create and also gote to prevent. In an actual game this kind of position would usually be resolved (i.e. live in seki or with points?) only at the endgame. So I'd put this scenario as "black to live at least in seki". Hints are not needed imo.

    This is seki.
