how to vary my play (turn cr) ?

[werero]

Im in the bb with Qd4d, Button raise sb call in I call.

Flop is 2d, 9d, 5s, button bet sb calls I call

Turn Jd, button bets sb folds and i checkraise

In this spot and other similar my turn CR always means two pair or better. That would mean that a very observant opponent could play his hand perfectly against me and even fold an overpair figuring she only got two outs. So i guess i have to mix up my play here and sometimes Cr with other hands than my premium ones? But what type of hands do I add here as CR-ing hands? Or do i even have to wory about this when im playing as low as 1-2, 2-4$ ?
