300NL - spot for big bluff with straight on board?

[rpr]

I raise the limpers on the BTN with a deceptive hand. I think UTG could have AA but more likely a small pocket pair or suited connectors. No reads on him. I think a 9 is part of his range so I don't bet the turn.

Do you put villain on a Q. Is this an easy fold or a spot for a brave bluff all in even though he bet big? He only has $100 left after his bet.

6-handed 300NL

Hero ($339.65)
UTG ($239.75)

Hero is dealt [6[img]/images/graemlins/spade.gif[/img],3[img]/images/graemlins/spade.gif[/img]] on the button

UTG limps, 1 call, Hero raises to $15, 2 folds, UTG calls, 1 fold
