I don't know what you expect to get him to fold on the flop. What do you think he has?
However when the guy calls our raise and no real scare card comes on the turn, I'm definitely not betting my turned equity cause I'm going to get BTFO a lot.
I think you have to think about the ranges before you bet the turn. 4567 5678 6789 kind of hands would have improved, so you need to strongly consider checking back on the turn. OK, play is bad at PLO25, and you rivered an ace, but I doubt this is +EV in the long run.
