TT, K on flop

[Sleepy Weasel]

I'm trying to learn how to play pocket pairs when an overcard flops. Previously I had been just check folding, but that's giving up way too much (right?). Here's a hand:

I have exported PT notes on UTG that has him playing 85% (of about 60 hands), and a note that says he'll call down with inferior hands. At this table I've seen him raise preflop with AQ and 66 (from MP), and bet/raise his decent hands postflop. Don't know CO.

Preflop: Hero is BB with T[img]/images/graemlins/diamond.gif[/img], T[img]/images/graemlins/spade.gif[/img].
UTG calls, <font color="666666">4 folds</font>, CO calls, <font color="666666">2 folds</font>, Hero raises, UTG calls, CO calls.

Flop: (6.50 SB) K[img]/images/graemlins/club.gif[/img], 5[img]/images/graemlins/diamond.gif[/img], 9[img]/images/graemlins/heart.gif[/img] <font color="blue">(3 players)</font>
Hero bets, UTG calls, CO calls.

Turn: (4.75 BB) 4[img]/images/graemlins/spade.gif[/img] <font color="blue">(3 players)</font>
Hero bets, UTG calls, CO calls.

River: (7.75 BB) 7[img]/images/graemlins/spade.gif[/img] <font color="blue">(3 players)</font>
Hero bets, UTG calls, CO calls.</font>

Is this SOP?
