Sorry, while I get your point, I have to disagree.  Personally,
I do not know what you state above (sound reasonable for me,
but may also be wrong IMHO).  But I quite well know how to write a program
that constructs the according table base, and finds by itself, how
to evaluate KRBKRP.

So, no direct knowledge is necessary in this case, there is meta knowledge
which can turn out to be sufficient.  This meta knowledge is partially
about chess and partially about programming computers.
