Is it possible to force a win? For RBK vs RK I've always been told it depended on the position, but no further information could be given, I've looked a bit and found nothing on the net. As for RNK vs RK, my guess is that it wins, but I'm not so sure, anyone has information on that?

I think I've seen positions like that in endgame books. You'll probably have to get yourself a good endgame book for details on this sort of thing.

R+B vs R is usually a win unless your opponent has studied the second-rank defense.

 

R+N vs R is usually a draw.

I just pulled up some statistics, at the 1500-2100 level R+B vs R is won roughly 50% of the time while R+N vs R is won roughly 25% of the time.
