Party 5/10, bet the river or induce a bluff from a L/AG?

[SinCityGuy]

The main opponent in this hand is a loose/aggressive player. He has been open raising with a very wide range of hands from any position. He usually slows down post-flop if he has nothing, but he's capable of making moves.. The interesting decision here is the river. Should I bet or induce a bluff? (The button is a typical weak/tight multitabler).
