It's funny that you say that, because, I found myself bluffing at a few pots yesterday on the river. Hard to do in this game, and you really need position to do it. I suppose that if there was one bet I needed to call here, it was a bet on the river by the button. I still think it's very neutral EV in the long run when a fairly passive player cold calls and then finally springs to life. It's funny, because, online, I call all day and twice on sunday in that spot.
