Now for my own problems, or at least those that can be decently discussed in this forum.
I don't have solutions for 29ac or 39dn. For 29, I've had a definition of painters in mind for some time, and it's the nautical one suggested previously, but surely 'chief' is a poor way of indicating the deduction of an initial letter? For 39, even after discounting 'attitudes' I'm getting nowhere.
If lilith are still following, I loved your story about 9dn! I had a similar problem with 40ac, which I was convinced had to be (C)HUMP. It isn't.
Finally, the Big One - I'll write separately about that.
