I agree.  I also wrote a special KRPKR evaluation function recently, and it has
turned out
to be useful surprisingly often.  It is probably useful even more often than I
notice, because
there are probably often important variations with this endgame even in games
where the
endgame never appears on the board.

As you say, writing a reasonably good KRPKR eval isn't all that hard.  It's a
good idea to
write some code for this endgame even if you always plan to use the full 5-piece
tablebases, because it enables you to see wins or draws several plies earlier.
Tablebases
are great, but they shouldn't be used as a replacement for endgame knowledge in
the
evaluation function.
