How? The position isn't a dead draw yet so why do you want the program to judge
it as such? True, in the given position, it is doubtlessly a draw with correct
play by both sides, but a slight change in the disposition of the pieces and
pawns, and nothing is clear yet. To say that just having an extra pawn in a rook
endgame with connected pawns all on one wing is a draw without looking at the
specific conditions would be a grave mistake. So not only is the knowledge
useless, but it's dangerous. You could add a large quantity of conditions to
make this knowledge more accurate and therefore useful, but I doubt very much
the cost would be worth it.
