I've only been at the table for a short while but villain doesn't seem to be too shy, he's running 50/27 with a 20% 3bet over 30 hands.

I'm new to PLO to apologies if this is a very simple situation.

Preflop seems fine to me, and on the flop I bet because I want to protect my hand, and also have the backdoor flush and straight draw so there's some turns I'll be happy to see. To be honest though I don't know if I should be bet/folding or bet/calling, does the 4 blocker make much of a difference?

On the turn I pick up the gutshot, but feel like check/folding might still be the best play, which leads me to wonder if check/calling the flop and check raising all in on turns which improve me might have been better?

As you can see I'm fairly lost here so any help would be much appreciated.
