Sorry to sound "stupid" but my point was that trying to find a "good" move
after the game is lost is not very interesting.  Much better to try to find
a good move _prior_ to things going south.

Rc8 might be good enough to draw.  I'm not so sure being a pawn down with an
active rook is that great if your opponent has a rook that is causing problems
as well.  I would rather try to find something _earlier_ in the game...
