200 NL - Would you make this river call?

[vizer02]

I have no reads on villain, as I don't even have 25 hands on him yet. On the river the pot size is 186.50 and it's 68.50 for me to call, so I'm getting just under 3:1 to call. I can't beat anything on the river, so how often do I have to believe villain will bluff this river in order for me to profitably call?
