Hero has TT in BB in his very first 5/10 session

[Fiddler]

This was kind of weird or possibly bad from my very first 5/10 session.

Party 5/10 6-max (5-handed)

Hero has T[img]/images/graemlins/diamond.gif[/img]T[img]/images/graemlins/heart.gif[/img] in BB.

UTG folds, CO raises, Button folds, SB folds, Hero 3-bets, CO-caps.

Flop: Q[img]/images/graemlins/club.gif[/img]K[img]/images/graemlins/diamond.gif[/img]9[img]/images/graemlins/heart.gif[/img] (~4.somethingBB)

Hero checks, CO checks.

Turn: 3[img]/images/graemlins/spade.gif[/img] (~4.somethingBB)

Hero checks, CO bets, Hero calls [img]/images/graemlins/confused.gif[/img].

I'm probably up against not much or a monster? Check-fold? Bet-fold? Or okay to do what I planned, check-call and check-fold river if I don't improve and he bets again?

I have only mined some 30k hands or so at 5/10 and hardly had anything on CO. I think I can safely say he is loose but that is about it.
