$1/$2 NL 6 max.

UTG limps. He plays like 40 / 10 or something. No reads other than that.

I raise to $10 OTB with [Qs]. The SB calls as does the UTG limper. SB seems like a fish as he keeps calling raises and folding the flop.

Pot $32. Flop [8s][4d]. They check to me. I bet $24 and they both call.
Pot $100 after rake. Turn . They check to me again. Do you just fire away here and hope for the best? Its not too often that a hand goes 3 way past the flop like this. Its hard to put UTG on a range when he plays 40% of his hands. Anyone play pot control and check behind here or do you fire away and commit yourself?

SB doesnt worry me much as he has like $80 left, but UTG is a wild card and hes me covered.

Sure, those are possible as well....not sure about K8, but A8s and 99 certainly could be there.
