Hello all. This is my first post. I have a question relating to the cross-referencing of puzzle answers.
For example, let's say the answer to 12-down is "Jerry", and my clue is a SEINFELD reference. Then, later in the puzzle, I have "Tom" as an answer. Can I say, "Nemesis of 12-down" for my clue? Or, since I referenced SEINFELD, it prohibits me from such a clue?
Also, when submitting to Will Shortz, is he OK with a couple of possible clues for an answer? Or, do you just send him your very best one? Thank you.
