    Why with P16-R19-S19-N19 O19 is seki? White has one more liberty at T19, and black can't T19 first because of self-atari. So white can Q19 or R18.... And it's not a seki, there are two eyes
    Sadaharu:
    The variation you mentioned is already inside

    To nate2: the sequence you mentioned shows a suboptimal response from the opponent, and in that case we should indeed live with points and not have seki.

    nate2:
    With the sequence P16, R19, S19, N19, the only accepted last move is R18, but O19 is Seki. Obviously Seki is a worse result, but the instructions say that Seki is a success. Maybe at the top it should say No Seki next to No Ko
    Ivan Detkov:
    Seki is a success indeed. I do not see a variant allowing to live without seki with the best play from both sides. Do you?

    heron:
    Doesn't C19 fail because the correct response is: C19 E16 F19 B19 (ko)? Also, what is wrong with E16? e.g. E16 B19 C19 is seki, E16 G19 F19 C19 B19 is alive right?
    caranthir:
    You're right. Problem modified accordingly.

    Should we get XP for each solution?
    caranthir:
    What to you mean exactly? You should reeceive XP for the first solution, and then ½ the value after a week, if solved the second time.

    1) C19 G19 F19 B19 A19 is wrong. It's a ko. The problem is "White to live. (No Ko)" 2) E16 B19 C19 G19 F19 seems to work too.
    Farkas:
    I disagree with your comment. Actually A19 is a hanami ko, which force the opponent to waste a ko-threat. Even after your opponent take it back, you can still connect and live.

    As Arctic said, one solution is missing: C19 G19 F19 B19 E16
