K9s Bet the turn?

[HerbieGRD]

It's entirely possible that I'm getting raped in these spots but do you guys really find that people are regularly peeling ace high flops with air when you raise preflop? I mean there are a lot of straight draws out there that you want to charge them to hit but these aren't guys I expect to bluff me with a worse hand on the river even if I check behind the turn. Plus we have considerably less equity when we are behind than villain does when he has unders and a straight draw. I guess I'm just not seeing the value in a bet here. Hand 1 seems really close but hand 2 seems like an easy check behind and fold river UI.
