    aesalon:
    This clearly turns it into a tsumego which does add some extra work with new solutions. The notable ones are 'bigger' responses to J18 such as L18, M18, and M17. Regardless if those are added for completion, I believe this was a good rework. Thanks posetcay.
    posetcay:
    You are welcome :) I reinforced white's outside to prevent larger moves from working.

    The solutions here need to be touched up. H18 D17 D19 E18 is a ko. So is just H18 E18. And why not just add a stone ~N17 to make it more of a tsumego?
    posetcay:
    Solution tree has been overhauled.

    M2 doesn't kill. P2 makes ko
    Ivan Detkov:
    Both moves are not the best.

    So after bM2, wQ3, how does white refute Q1? Seems like it kills similar to 311.
    d4rkm4tter:
    Your moves have been added.
    @caranthir I agree.

    Sadaharu:
    In the correct answer's sequence, B can still pincer at J2 to go out when white tries to kill at P1.
    caranthir:
    Trying to fix that by solidifying attacker's shape would enable a number of other solutions and therefore break the problem a bit. Maybe we can regard the defender crawling on the second line (in your variation) for quite a number of moves as a good enough result for the attacker.
