I'm not sure about this hand. Looking back, I guess I should have re-raised the min-raise pre-flop. On the flop, I was pretty sure SB was on the jack, but I didn't have a real read on MP. I didn't think either of them flopped the straight though, and didn't think of the implications of the Queen on the river.

After the flop, should I have been more aggressive (with the scary straight?) or considered folding?
