I thought I'd kick off an opposite form of the Pet Peeves thread, both to talk about good narrative tricks and clever use of tropes, as well as to help new authors find examples to follow as well as pitfalls to avoid. Of course, with such a thread, there may be the inclination to pull a humble brag, but we'll just assume good faith here. One nugget of awesome I like to see is the clever hinting of an important character, but in a way that the reader doesn't realize that the name is anything other than a throwaway mention. Also known as Chekhov's Gunman, it's especially cool if said character later ends up becoming a well-developed and -liked person in his/her own right. So, feel free to chip in with other nuggets, and don't be afraid to mention particular examples (note, TOS and forum rules still apply).
