1/2 6m Overpair Fold

[cts]

I'm a limit player that's just starting to learn some no limit (playing shorthanded only), so this is my first post here. My turn play was really weak, and by the river even 78 got there. What do you do here on the turn?

I'm also kinda curious on my stats, since they are completely different from limit (at which I've been playing from 10/20 to 30/60). I've only been playing the 6-max games and my stats over about 10k hands are

VPIP: 26.6
PFR: 16.9
WTSD: 20.89 (this stat has been falling as I've been getting better)
AF: 2.28 (total)

Are these in the right ballpark? Too tight/loose? Thanks for the feedback.
