    Looks like we didn't realize previously how complicated the solution of this tsumego was. Added refutations to P19, S19, R17 and added the real answer that starts with hane as a previous comment mentioned.
    Ivan Detkov:
    Wow, this is deep.

    Sorry, that sgf looks empty (only the starting position, no sequences) when I open it.

    Here are the main line solutions from two Gokyo Shumyo books I own. As Frofroyoyo said, they seem to always start with the hane.
    posetcay:
    Resolved.

    Frofroyoyo:
    The starting move in all standard solutions to this is a hane on the first line, yet it isnt considered correct on this platform.
    Ivan Detkov:
    Please show the sequence of how the standard move works. Prove your point.

    Playing D17 before F18 seems also possible to kill white and live
