2 overpair hands

[Proofrock]

I mostly play no-limit, but I'm trying to improve my limit game since the only live games within 200 miles are limit. Anyway, as soon as I got raised in both of these hands I figured I was toast, but word on the street is you go to showdown a lot in limit with TPTK+.

Hand 1: UTG is solid, CO is 38/5/1.8 over 80 hands. Can I safely dump this on the turn, or does CO have T8 enough to call? C/f the river?

Hand 2: Villain seems bad and laggy - 60/18/0.7 over 50 hands. I called down because Villain seems fishy and there's always a chance he has 9[img]/images/graemlins/heart.gif[/img] 8[img]/images/graemlins/heart.gif[/img], but the check/cold-3bet seems like a ten pretty much always, doesn't it?
