The above solutions look correct to me. 35b has an interesting line. Find the Black continuation:

I can't find the interesting line. The obvious move :b3: at h19 connects :b1: to the outside and thus falsifies the second eyes. Am I wrong?

Heh, for some reason it looked to me like H19 for :b3: didn't work. I was wrong. I was looking at a different move for :b3: that does seem to work (G19). Of course, given I misread H19, there's a good chance G19 doesn't work the way I thought it did. :mrgreen:

I think :b3: at G19 fails because white can sacrifice the corner and live on the right?
