    Sorry, I meant this initial sequence: S2 T2 T4 S3, it is marked as wrong for the defender (whyyy do the colours change!). It seems to me that after continuing with S1 R1 Q1 T1 T3, the hero is alive.
    posetcay:
    Added correct defense against A16.

    Why is B18 A17 A16 B17 wrong? Seems like continuing with B19 C19 D19 A19 A17, black has one more liberty.
    Ivan Detkov:
    A17 is not the best answer to B18 and the entire sequence is sub-optimal.

    D1 result is seki need to fix solution. And as B2 is a ko it's not good as solution.
    Ivan Detkov:
    D1 is 2 eyes. I removed ko as a solution. I also changed "Black to play" to "Black to live".

    GoGentleman:
    This is a Ko. White attaches at B2, than black would re-attach at A2, which leads to a ko
