Fold a straight on turn in unraised pot when board pairs?

Yeah so i hate this spot, i figured the only hand he really could have on the flop is 97 or a set so when the turn pairs the board im essentially screwed unless he has 97 so who here folds this?

I expect we're ahead about half the time here, which means with what's already in the pot, this is a very easy push.

im not folding, for your turn play i like betting less than 1/2 villains stack b/c they will be more likely to stack off with weak hands or sometimes they will bluff raise you

edit: this is a very minor consideration though
