I need to bet this flop right? I was thinking this is the sort of flop that anyone with any pair is betting always, so I was hoping to checkraise the field. Turn I can't lead out though (can I?) and I feel bad calling because I see this as easily getting 3-bet or even capped and if it is I think I'm drawing to 3/4 outs.
