hit gutshot on paired board

[yawak]

Full ring 5/10 nl on bodog

Fish (40/8) with $1500 behind limps in, I raise to $50 with T [img]/images/graemlins/heart.gif[/img] 8[img]/images/graemlins/spade.gif[/img]. Big Blind (13/5) with $1000 behind calls and so does the fish. I cover both.

Pot is $155 and the flop comes Q[img]/images/graemlins/spade.gif[/img] 9[img]/images/graemlins/heart.gif[/img] Q[img]/images/graemlins/club.gif[/img].

Both check and I make a continuation bet of $80. Only the BB calls.

Pot is $315 and the turn card is J[img]/images/graemlins/heart.gif[/img]. BB checks and I bet $175 and he check raises to $550. Should I push against this nit?
