Hi, i need some postflop advice. I have to recall the action since it was an anonymous table at MPN and u can't save hand histories.

0.5/1 blinds
6handed
Hero (CO) ~200bb
BU ~200bb

folds to Hero who opens 2.5bb with AsQs, BU calls, rest folds.
FLOP: Qd Jc Td Potsize 6.5bb
Hero bets 4bb, BU calls
TURN: Qd Jc Td Qh Potsize 14.5bb
Hero checks, BU bets 10bb, Hero calls
RIVER: Qd Jc Td Qh 4c Potsize: 34.5bb
Hero checks, BU bets 67bb, Hero ???

I don't have any reads on villian. My only asumptions are that he is a reg at this limit and he probably perceives my range as capped.

How do you play this hand?
