No offense, but these hypotheticals ar very difficult because its so hard to just dream situations where you should and shouldn't call. Generally, i would feel comfortable saying that when he calls the flop and turn, it's more likely that he has a weka made hand or a showdownable hand of some sort since he has made no effort to get you to fold. If he was on a gutter draw with T-8 and he's good, he's putting in a raise somewhere. So, i guess against very good players you have the best hand about never here. Some exceptions are when he could have K high on some 2237 board, but he won't usually bet the river there.
