Heads up with the bare nut low draw

[yukoncpa]

I’m in a loose 2-4 limit Omaha 8 game with 7 players. I’m UTG and am dealt A27K rainbow. I limp and everyone folds to the button who limps. Little blind folds BB raps.
I have no reads on opponent, but assume he plays like a typical online 2/4 O8 player.


Flop is 56Q rainbow

BB checks I bet, button calls, BB folds ( It is now heads up in small pot and I’m oop).

Turn is 9 ( board is still rainbow and all I have is nut low draw)

How should I play the turn? If betting is correct, I assume then that I should also bet the river if I miss.

edit - also, even cs's will sometimes fold very weak hands that have me beat.
