I'm often finding this kind of spots a little difficult, coming from a NLH background. Do we bet turn to make him fold his hands that still can improve to 2 pair or trips to beat us?
It prevents us from getting bluffed a lot on the river, but by betting turn we isolate ourselves against a range that's beating us. Does that even matter in PLO?

If you check turn, on which rivers besides the flush (if any) with you call villain's lead?
