There's something in psychology called the "availability heuristic." What it means is that people tend to over-estimate the occurance of memorable events while downplaying the occurance of routine, non-memorable events.

I think you may be running into this in these situations. When you bet the turn and lose to KK or a flopped straight, you think "wtf?!" and remember that event. On the other hand, when you pick up the pot you never give this hand a second thought and you've completely forgotten about an orbit later.

I think you pick this up uncontested far, far more often than you run into a trickily played overpair, a slowplayed straight, or a misplayed top pair. It's just that you remember the later cases and forget about the former.

Seriously, you can make a good case for betting this turn with literally any two cards. I've seen that advice show up in multiple books (I'm thinking Yao and Freeny, but there may have been others as well. Harmon's chapter in SS2 is another possibility, but I would need to review that one). If it would be reasonable to bet this turn WITH NOTHING AT ALL, then it has to be right to bet the turn with a legitimate hand that figures to be good at the moment.
