i would probably check/call all 3 streets here. we are raising oop against only 1 opponent so we shouldn't have a lot of 65 in our range therefor he should start bluffing. we don't wanna miss that value by cbetting and fold out hands that we have absolutely crushed but still could bluff.

I agree with Jakub that the villian is unlikely to have the the nut-straight.

Queens or Kings could be in the Villians range so it's possible he has a set of two pair, so he could be semi-bluffing here, I would probably call the river, but I'm new so PLO so don't take what I say as gospel.

I would bet flop check call turn and check call river.

As played I think we can fold river. We block lots of draws he can bluff with and he can have tons of 6x.

I like jakubs line of keepin in ALL his range and let him do the betting.

If I bet flop I will bet turn too for value. Doesnt matter if we get raised here since have so good EQ with our two FD's so more important to take value from same str8 and 2p/sets.
