Weak-tight KK hand

Hi,

I've lurked for a while played $5-10 6 max for a while, just starting a stretch in $10-20 (~5k hands so far).
UTG+1 70/18/1 over 500, plays big pairs and sets tricky postflop. Often waits too river.
SB is 24/8/1.3 over 600, and tends to overplay overpairs from what I've seen.
No info on BB.

$10-20, 6 max
Pre-flop: (6 players) Hero is CO with kd; kc;
UTG calls, UTG+1 raises, Hero 3-bets, Button folds, SB Caps, BB calls, UTG folds, UTG+1 calls, Hero calls.

Flop: 8c; 3c; 5h; (17SB, 4 players)
SB bets, BB folds, UTG+1 raises, Hero calls, SB 3-bets, UTG+1 calls, Hero calls.

Turn: qd; (13BB, 3 players)
SB bets, UTG+1 calls, Hero calls.

River: 7d; (16BB, 3 players)
SB bets, UTG+1 raises, Hero folds, SB calls.

Results:
Final pot: 20BB

On the flop I was pretty sure I was ahead, and that the small blind would 3-bet any overpair if I just called, the only big club draw I'm worried about is AQc since I've got the Kc. I called two planning on raising any turn except an Ace, hopefullly getting two big bets from both opponents.
As you can see I chickened out on the raise on turn, I really didn't like the Queen, should of been an easy raise right?
My weak turn play made the river more interesting, if I call I'm only getting 3-bet by QQQ in the sb, but I didn't think I could win 1in10 against the UTG+1 player. Although I thought I might still be beating the SB (JJ-TT, AQc maybe). [img]/images/graemlins/diamond.gif[/img] [img]/images/graemlins/club.gif[/img]
