An excellent puzzle indeed. Thanks Phi. I’ve got two elements to resolve for which I’d appreciate pointers...
29d “Removed black bishop? Sound content with removal of pawn (4)”. I think (?) I have the correct answer, but can’t parse it.
I cannot identify where the 8th misprint comes from. I know what letter it needs to be, and there are only six possible clues it can come from. But I just can’t see it.
