What do you think? Is my river bet a good attempt at hogging the whole pot, or am I just begging to get quartered?

I hate the $2 bet by mp3 on the turn almost as much as I hate the way the button and you flat called it. That usually screams made nut low that doesn't want to be quartered. If they are gonna bet it like that then they are usually not going to fold, even when you pot the river.

If you had even something as weak as top pair then I'd say it's worth a shot, but I'd be really shocked if you didn't get a quarter or sixth here.
