All my opponents are rated fish after a small sample. The table was very loose and players were calling down with all sorts of holdings. Raising the turn with bottom pair etc.

Preflop: Hero is BB with T[img]/images/graemlins/club.gif[/img], A[img]/images/graemlins/heart.gif[/img].
UTG calls, <font color="#666666">1 fold</font>, UTG+2 calls, MP1 calls, MP2 calls, <font color="#666666">2 folds</font>, Button calls, <font color="#666666">1 fold</font>, Hero checks.

I don't think I should have raised out of the BB. I think AJ and I hit it. VS 5 opponents my hand is probably best. Any thoughts on pre-flop?

Flop: (6.40 SB) 6[img]/images/graemlins/club.gif[/img], T[img]/images/graemlins/spade.gif[/img], 8[img]/images/graemlins/diamond.gif[/img] <font color="#0000FF">(6 players)</font>
<font color="#CC3333">Hero bets</font>, UTG folds, UTG+2 calls, MP1 calls, MP2 folds, Button calls.

Turn: (5.20 BB) Q[img]/images/graemlins/heart.gif[/img] <font color="#0000FF">(4 players)</font>

This is where I get messed up. With 5 outs I think I can see the river but I may be drawing dead to a straight. I discounted my outs to 4 just to be conservative and the pot seemed big enough when it was back to me after I already put one bet in. Should I take one off or fold figuring someone has a straight. These guys will raise with anything and I may be best. (slim chance but you need to account for it) Thanks for any thoughts.
