This doesn't need to be a "rule".  If I were playing and reached a known drawn
position,
and it became obvious that my opponent knew it was drawn as well, I'd offer a
draw.  Crafty
will do this automatically, in fact, after the draw score is seen for a few
moves and the opponent
doesn't make a mistake.

But it doesn't take a _rule_ to make that happen.  It is called "courtesy".
