I'm not sure here but I'll give it a shot as it means I'll come back to see what other people say...
You can probably still jam pre, although I still flat weaker aces >20bb myself
Flop - I think you can raise a little bigger as villain likely has a piece of the board.
Turn - Now I'm treading carefully. I don't think I can fold here though. I do like the call as if you jam you're pretty much only getting called by a king or straight.
River - Call imo. Not loving life here but I think you're right about splitting with aces.
I'm really stumped here, maybe someone else can have a better go
