Stars PL(0.25)

[kapw7]

Apologies if this looks too bad or stupid but it is my first post here and my PLO experience is 2 days long

BB seems to know what he is doing and is tightish (considering that the table is ultra loose) preflop but generally very weak post flop. UTG is a big donk who loves to minbet the flop OOP every time.

What hands do you think he's folding there given the stakes and the read? Most likely not a small flush but he has to fold straights and sets or am I way off?
