When to bet the turn in PLO8?

Seems to me they can't both be horrible! Anyway, I would say that MP's call is fairly bad. Button's bet is correct, I would play it this way every time. You generally assume if you have AAxx and someone else raised preflop that they have a good low hand. On this flop, that means that unless MP has a miracle flop fit like A2 plus two of (Q35), button is ahead (he knows that MP doesn't have the nut flush draw). On the turn, button knows he's ahead for high and MP is chasing low 80-90% of the time. And he should bet full pot so that MP doesn't have proper odds to chase.
