NL25 - Improper play chasing nut flush?

[Aceium]

I would probably be cbetting on this flop since it's unlikely to hit them. Calling a minraise on the turn is ok because you're pretty sure that you have 9+6 outs (generously). You hit on the river so it's an easy call since it's a shortstack that shoved. You win this pot much more often than villan will have a FH.
