10/20 live hand--small connecters/counterfeited

[tdarko]

the villain is a tight player, i am not going to say he is ABC b/c his postflop play isn't, but his starting hands never really change. he covers me.

villain raises in MP to 80, i call on the button with 4 [img]/images/graemlins/spade.gif[/img]5 [img]/images/graemlins/spade.gif[/img].

flop is Q [img]/images/graemlins/diamond.gif[/img] 5 [img]/images/graemlins/club.gif[/img] 4 [img]/images/graemlins/club.gif[/img]
villain checks, Hero bets $150, villain calls.

turn is Q [img]/images/graemlins/club.gif[/img]
villain checks, Hero???

worst card here, am i done with the hand? what is my line for the turn?

on the flop its about 2 to 1 for him to draw to a flush, this doesn't seem like something he would do...but obviously he could.
