I dunno about betting the river. What reasonably reasonable hands are we ahead of at this point? The only ones that come to my deformed mind are AQ and AJ. I think hands like AK, KQ, even a set are all possible considering the action. Sure, these hands should 3-bet the flop, but they could be scared of two pair (in the case of AK), or going for an ill-advised slowplay...
I don't know, when I actually type it out, it doesn't seem too too likely that a set or top two would play it like this. But still, I'm not sure I like a value bet that's really just hoping to see either AQ or AJ.
I'm pretty much A-okay with this hand as it was played.
