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... >the point about Rc8 is that rook endgame theory knows tons of examples where it >is better to play a pawn down with an active rook than a passive position with >the same number of pawns.
