Fencer: I don't know, if it's fair to say something about an ongoing game, but as it doesn't seem to be a tournament game...: Yes you should go on playing. Have in mind, that One Rook vs. Full Defence (properly setup, like at the moment in this game) would be draw, but vs. an uncomplete defence a rook always wins.
