TPTK Turn & River Play: How many bets you want goin' in?

[MisterKing]

Villian is 31/6/1.3 over 400 hands, but seems to be playing a little tighter/more aggro than that in this particular session. I am almost 100% sure MHIG on the turn, for what its worth. Given that read, and a lack of other specific knowledge of the opponent, how many bets do you want to go in on the turn? The river? I have my own thoughts about the hand and will share in a bit.
