to me it seems that most pieces are grounded to place, and swaps and other waiting moves will not improve the position by queening the pawn or gathering matereal.
thinking about it for a second more.... maby if you manage to swap the b and g rooks. and then move your king to d2 and activating your queen to help the rook and bishop looks like a good plan. problem is that these moves were static. meanwhile the opponent can free his knight and attack the pawn... or the bishop. anything...
sorry i couldn't have been of much help, in summary: you might have had a win, (like a 50 moves around the board and reppetition to gain thinking time with no clue what you are doing untilll the opponent breaks), but it won't be worth the headache.
This position was reached in one of my games. I could not find a good way to continue and played Rh2 and offered a draw. The draw offer was accepted.
Do you see a way to win this?
