I've gotten this far. Not quite sure what White's best next move is.
This doesn't look too bad...
unkx80: White 1 at a works the same way. =)
Perhaps we should step back to here. The problem with Black playing anywhere besides the marked spot is that White will play there which is very big for her.
I'm stumped. I've tried other variations, but this one still seems the most promising. If you know the answer, please don't post it here, but perhaps show the first two moves of it.
 The new diagram.
