A turn bet would definitely be the most standard play and the best play against competent opponents but against a fish you can mix it up with a play like this. I'm still not a big fan of it since you don't know how he plays postflop. A lot of the loose passive people will check behind any weaker pair on the turn so you will lose value. Besides, he has a pure float pretty much never.
Oh and congratz on moving up to midstakes?
