Did you ever consider Black's resistance with 3 here ?

The solution sequence will become longish ;-)

Wow, what a case of tunnel vision. When I plan the first move, I know the issue is reducing White's liberties, but I got so caught up in proving White can't escape that I forgot it.

Anyway, I still can't see an answer. I'll have to keep looking.
