I have Qs6h and call button 2.5x open (slightly over 100bb deep)

Flop is: 6d9dQh 

Villain CBETs .80 POT and I check raise kind of big size 1.2x pot ( a little under 4x his cbet size). HE CALLS

TURN: 7s 

I lead out POT and VILLAIN CALLS

RIVER: Tc

I check VILLAIN SHOVES ALL IN slightly less than POT

I CALL. 

Lets say he is standard balanced opponent who is good. I block Q8 and I don't block diamonds which will bluff 100% of the time id say. Also I'm not sure he can call with a mere straight draw on the turn so I'm only worried about Ad8d and 8xdd. 

I get to this spot with this line with only Q6, Q9, and 66. I am not at all worried about being exploited on this river...if he wants to pay as much as he did to get here to maybe have an opportunity to bluff ATC then be my guest. 

THUS, I think its either always all call or always a fold. Depending on whether or not the average player will have a tendency to bluff too much or too little in this spot. I'm going to run the combos and get back to you guys but I want to hear what you think.
