My plan was to fold the turn UI ... but .. ?

[Mig]

Vilain is very loose preflop something like 50/10/1.5. I'm not really interested in putting anymore bet but the Ace on the turn just impoved my hand a little... Should I bet and check/fold the river ? What is the default play vs unknown.. My plan was to check/fold the turn unless I improved which I did somewhat...
