As far as sample lines go, I wanted to actually post one here, but after having the Chessmaster engine play itself from this position, a 79 move marathon ensued. For obvious reasons, I decided against posting it. None the less, if broken down very well, it appears that this ended up an extremely tedious affair.
If black starts with a passed pawn I think it's a straightforward idea (not moves anyway) to play for the win through that. We can see black has better pieces, so it may just be a matter of time.
Not that the specific moves would be obvious to me, far from it... but that seems to be the idea anyway.
