AKo - 0.50/1.00 Stars - River Line

[Goodnews]

Villain's stats hover in the 18.75/6.25/0.67 over 16 hands (not a significant dataset but helped me make my decision on the river). He didn't seem out of line in any of the hands I saw him involved in.

Final Pot: 7.75 BB

I obviously don't like this river, and it is difficult for me to put him on a hand he, with his VPIP so low, will call a river bet but not raise me with a better hand.

Just wondering if this should have been a c/f instead of a c/c. Can't really justify hoping he would bluff at this river given the low AF.
