I have 24 extra words but am not overly happy about one of them, assuming it is one of them, of course.
23a says the answer "is including good" which is enough for 99% of solvers to realise it includes a G. My problem it also says "including good opening" which is, of course, also G, so while i"opening" could indeed be said to be redundant, it is, in a literal sense, absolutely correct - or is it not one of the 24?
If the response would be considered a spoiler then please say so, it's just that I looked back over previous posts and some were way more explicit.
