If you're going to bet any decent amount, then you should shove given the stack sizes against any reasonably thinking Villain. Unless Villain knows your game pretty well he probably thinks your range is polarized. Even if he calls a shove half as often as a ~200-ish bet, it's higher EV to shove. Against most villains I bet this river as villain would need to have severe FPS for checking to be profitable.
