99 overpair vs. a 3-bet

[Luke]

Party, 3/6 6max - 4 handed at the moment.

I'm new to these games in general and have only recently sat down at this particular seat so I don't have much of a read on anyone.

The only thing I've really gathered so far is that UTG does not play well and does a lot of open limping.

UTG limps and I raise on the button with 9[img]/images/graemlins/heart.gif[/img], 9[img]/images/graemlins/spade.gif[/img]. The SB 3-bets, BB folds, UTG folds, and I call.

Flop: 6[img]/images/graemlins/heart.gif[/img], 7[img]/images/graemlins/club.gif[/img], 5[img]/images/graemlins/club.gif[/img] <font color="#0000FF">(2 players)</font>
SB bets out and I raise - SB just calls.

Turn: J[img]/images/graemlins/heart.gif[/img] <font color="#0000FF">(2 players)</font>
SB checks and calls my bet.

River: T[img]/images/graemlins/diamond.gif[/img] <font color="#0000FF">(2 players)</font>
Check, check.

A few questions:

Anyone capping this preflop?
Anyone not raise this flop?
I assume the turn bet is automatic (and ps., I'm probably folding to a turn CR - hope that's not a big mistake.)
Clear value bet on the river?

Any comments welcome, thanks...
