Well, I'm pretty sure this works, but I guess I'll find out one way or the other over the next few moves
I can give variations if anyone requests, but there are quite a few of them, none very long, and all the ones I've looked at end happily for me. The basic theme is that, while my wall is now alarmingly short in liberties, both the white groups currently blocking it in are even shorter on them.
There could be some longer-term problems if white succeeds in keeping O15 alive, when my M17 group will struggle for life. But I'll cross that bridge when (or perhaps if) I come to it - I've been unable to find a better move than this one. I contemplated first playing the atari at O14, but didn't like the look of the following variation at all, so I didn't play it:

group is interlocked with the black 4-liberty group and white has sente. If there aren’t any tricky tesujis black will lose the
stones, but they were dead anyway. My point is this: white need to spend a move to save his cutting stones so black can extend to Q18 and it now stands 7 liberties to 4. Black has nothing to be afraid of.
