Not sure what your table image was at the time but unless it was that of a maniac, his lead and 3bet on the flop out of position screams AK or set (competent regular at 10/20 would be certainly capable of leading into you with a set there knowing you are aggressive and/or have overpair). I guess he can have Ah8h too.

All in all, that is a horrid turn card and I probably fold on the turn without any other reads on villain.

But the way it was played, you pretty much have to call on the river getting such a good price and having the slim possibility of overplayed 6h7h or K5s.
