Aesthetics is always a subjective thing, of course.  My personal preference
is to always let the engine figure out as much as possible by itself, based
on general knowledge without too many complicated special cases.  A huge
lookup table containing the exact number of plies to mate for all KQKR
positions is about as far from general knowledge as you can possibly come.
