I am very new to Go, and I found this tsumego, that I have been trying to figure out. The solution is trying to live with a ko in the corner, but I think that it only brings death for Black. The solution makes sense to me if you are only trying to create the ko. I see the ko, and I see how it can move down into White territory. But it seems to me that if at B-19, it kills Black as it does not have a response that gains the Black stones any liberties, or is a ko threat. kills with D-18 (and leaves White with great eye shape). Am I missing something, did the originator miss something, or is the only object of the tsumego to get the ko? Normally, it is life or death, and the proposed solution for Black only leads to death as far as I can see.
