I am very new to PLO. I have played less then 2k hands total this year so these spots I find quite difficult.

Firstly should we be c betting this flop? The more I think about it the less hands he has that fold this flop if he will be calling hands like JJ and QQ. And when I do the calcs in poker juice against a lot of his continuing range we are 50% or less anyway. This kinda spot in a mtt is cbet loads but here I'm starting to veer more towards checking back. Any thoughts?

Villains RFI from UTG is only 8% and when they ch/c flop I gave him a range of KK, QJ, KJ9+, T5, K5 and QQ,JJ. I thought he might ch/rr his weaker sets and his KT hands. When the A comes on the turn I think quite a lot of those hands either got there with QJ since I think that's a big part of his range or they are folding to a bet with the exception of KK. So whats the best line going to be here. Should we ch back and keep his range wide and hope for some bluffs from Q and J blockers or should we be aiming to get max value out of KK or something like 2p with fd?
