$100 PLO, interesting PF dynamic AAxx in SB

Very interesting dynamic, UTG is a total donk, BTN is a solid regular (seems to be around when I have been lately). UTG just lost huge pot vs the BTN, has raised/3bet PF last 3 hands and has not reloaded.

Hero (SB) $110.50
UTG: $18.90
BTN: $284.75
3 other players

Hero is dealt :Ah: :As:

UTG raises to $3.50, 2 folds, BTN calls $3.50, Hero raises to $7

How'd I do?

I like. Just keep in mind the BTN is putting you on AAxx, maybe KKxx unless you do this a lot. If UTG happens to call it's going to be hard to play, but that sounds unlikely.
