    Leo Wagner:
    I couldn't solve this one, and neither could leela zero, actually. I could maybe try playing the 2-1 point to kill through a Ko, but that answer is wrong, apparently. I'm not sure about this problem.
    d4rkm4tter:
    Yeah, LZ is bad at tsumego.

    There is actually a Blind Spot collection which has the same problem but gives 200 xp
    d4rkm4tter:
    Ok but we don't change it. The xp depends not only on difficulty, but on the collection too.

    B1 kills via ko but the problem says "White to kill" and doesn't say "No ko" like with the others. Am I missing something?
    caranthir:
    There is a ko-less killing variation.

    It seems White S1 kills, no ? Black P1 & R1 are self-atari, O1 & T2 are too slow so White capture and Black T1 is a ko (not forbidden)
    caranthir:
    There's a ko-less killing variation, which is the only accepted answer.
