Villain in this hand is loose/passive. He typically limp/calls preflop and calls any flop cbets if he has isd+. Should I be doing anything differently on the turn? We are not heads up, I'm just too lazy to list the other players that are not in the hand.

Bodog 6max NL BB is $.50

Hero is CO ($51.00)
Villain is SB ($62.50)

Preflop: Dealt to Hero
2 folds, Hero raises to $1.75, 1 fold Villain calls $1.50, 1 fold

Flop ($4):
Villain checks, Hero bets $3, Villain calls $3

Turn ($10):
Villain checks, Hero bets $7, Villain raises to $14, Hero calls $7

River ($38):
Villain bets $16, Hero??
