Day #36 December 10th explo posted some 330 series of problems five years ago. I am not sure I am so well disciplined. Ample response might help. At Topasz' request I open a new thread on each series. Isn't it flooding the Study Group too much? Maybe a new section: Tsumego?

ah i thought of that variation but for some strange reason i thought white wouldn't take the stone at 4 and would play 4 at 6 not thinking that white if cut off would be short of liberty's and would die anyway
Just noticed this what if white reply s like this, seems to me black is dead now.

@Tibul,
combine your teaching with that of DrStraw and you've got the solution ...

ah now i see it i overlooked that black 5 puts whites group in atari so white cant play to the left of 5.

Yeah, don't know how much I'll be posting in these anymore since I can't trust the problems or that the poster said he'd check them from now on before posting them. Nothing personal, I just like to use my time more wisely & I'm just a small segment of the audience anyways : )
Best of wishes, logan

While I agree that it would be nice to have verified solutions, I think the time spent on reading these isn't entirely wasted. I understand it can be frustrating, but hope that the fact you exercised your reading makes it slightly more bearable

No problem, Logan. I accept your reservations. The problem I face is that the GoDiscussions files were not saved in very good shape. All tags are removed. All comments are in one heap such that it is not clear which post refers to what problem. Post on a new series are interwoven with posts on previous series without numbers, dates or diagrams. I checked this problem and I was triggered by
"@Tibul, combine your teaching with that of DrStraw and you've got the solution ... "
by Tommie 3 or 4 dan
into believing there was a solution. Maybe my effort was not sufficient. It is of course your own choice to participate. Maybe you want to join in again later.
