Thanks a lot stalkor I missed move now that I see it I really like the problem. Sorry dusk I mislabled the problem its problem 63.

Yeah, that appears to be the solution to number 63. I couldn't find it at first, and I just thought it was set up wrong. Gah, my tsumego skills are so out of shape.

Hey guys i just cant seem to find the solution after

Thanks a lot didnt think of (a) which is bizarre as the problem before this one (which is shown above) is almost exactly the same and I found that answer right before attempting this one.

black can live with a, and there really isn't a way for white to get rid of that in sente, so black can probably escape along the bottom, i think...
