A lot of draws will have bluff raised at the pot at some earlier point in the hand. I think it is very read dependent whether to check/call or check/fold the river, but I would strongly consider check/folding here. Unfortunately, you bloated the pot with a pretty poor hand, so now you're reduced to guessing a frequency that is very hard to estimate.

My default play with A6o OOP would be to call the raise before the flop and check/fold this particular flop.

Much as it pains me to say this -- as I have made quite a tidy sum off of players 3betting Axo OOP and inevitably making big errors postflop -- but 3betting Axo OOP should be the exception rather than the rule. I probably 3bet it about 10% of the time, probably less than that if we restrict to x <= 6.
