$115 NLTRN-Big hand against a tighty

[Indiana]

So this guy is very tight but i've been shoving my weight around....When I improve on the turn I felt that he wouldnt bluff at me on river if i check here so I may as well just value bet and use my loose image to hope he calls me down....How do you play this turn?
