I agree entirely.  Adding endgame knowledge is very difficult, especially if you
want to
keep the code general rather than writing huge amounts of code for dozens of
different
special cases.  And if you give up and start writing code for all sorts of
special cases, you
face the ugly problem of evaluation discontinuities when pieces are exchanged.

Not only the eval, but also the search is difficult in the endgame.  All the
well-known
selective search techniques seem to fail miserably in the endgame.  Chess Genius
does
something which seems to work rather well, but I haven't been able to figure out
what
it is.

Is Borer a new name for MessChess, or an entirely new engine?
