There are only two hands that made it on the turn, 97 and 74, one of which is *supposed* to be very unlikely (but is never really as unlikely as it's supposed to be).

But there are a lot more hands that picked up a new draw on the turn, so yeah, I think you have to raise here.

To be honest, though, I'm still unclear on what to do in situations like this if you raise the turn and get reraised. I usually end up calling, but you're definitely going to be shown the straight, two pair, or even A8 a significant percentage of the time. Of course, you also get shown stuff like any random 8, any pair with a draw, or even just flat out any pair (including crap like Q3, "hey look, I've got a pair, and I think he's on a draw, so I'm going to just take it down now"), given a sufficiently donkish opponent.
