50NL overpair vs alot of action on flop

[BevillTheDevil]

UTG is 47/18/1.74 900 hands he doesnt play TP/1 pair hands very aggro but will call down with them i def think he could play TT-QQ this way and probably draws too. Button is 47/9/2 after 50 hands not very good at all plays random like and probably could be doin this with alot of hands. Whats your line here?
