I'd probably fold the flop C/R to an unknown. This is a set, 2 pair,or a bigger Ace a lot of the time.
If you call the flop C/R you obviously can't fold this turn, as villain would be firing with their whole range. I don't think raising achieves much, so just call the 6$. Probably call any bet on the river as well, and just hope the small blind is bluffing or an idiot with a smaller ace
