QQ in a tough spot

[pna]

NL 400 @ OnGame 5-handed. Effective stacks $330.

utg is a loose donk. CO is new player at the table.

utg minraises and CO makes it $30. I call from BB with

Q[img]/images/graemlins/heart.gif[/img] Q[img]/images/graemlins/spade.gif[/img] (should i raise allmost allways? Something like $100 to go or so?)

Pot: $92

Flop: 6[img]/images/graemlins/diamond.gif[/img] 9[img]/images/graemlins/heart.gif[/img] 3[img]/images/graemlins/club.gif[/img]

I bet $60, utg calls and CO makes it $170 to go.

I'm not 2much worried about utg, but how likely is it that CO has me beat here? I folded, but i'm not too happy about it
