    This is a good finding. It requires some efforts to rework the solution tree here. It makes sense to change the color of P3 stone to avoid not-well defined sequences.

    Maybe that would be for the best. A stone at P3, perhaps?
    Ivan Detkov:
    I agree. It should be fixed now.

    Hi, Ivan. What if the defender plays L19 instead of K19, making the throw-in to worsen the defender's shape a non-option for the attacker?
    Ivan Detkov:
    Uh, I did not see this move. It looks like a refutation. Should we add a stone on the right?

    Hrewsahgs:
    I'm not sure what the attacker can do if the defender plays M18 instead of K18 in the correct line...
    Ivan Detkov:
    It is an excellent question. I added this sequence and it is quite interesting.

    Added refutations to L17 and corrected the answer.
