Simple value shove or check call river?

10/20NL full ring effective stacks $2150.

Don't know much about villain in this hand, but he seems a bit loose, that's about all I can say.

I raise A9s UTG+1 to $80, villain calls on the button, BB calls.

Pot: $250

Check call to induce a bluff from flush draw or shove and hope he calls with an ace?
