Okay, I don't know how to convert hand history's for this site so I just copied HEM to clipboard and pasted here. I think I made a bad river bet here, but I want to know what other players think and how they would play this. 

My opponent was loose/aggressive pre-flop and loose/passive post-flop. I don't know what he does with missed draws on the river. My reason for betting wasn't really well thought out but I guess I didn't want to get bluffed off the best hand. 

I know he's never folding better and never calling with worse. Does that make this a check/fold on the river and hope to showdown? Even on the turn its hard for him to fold a 9. Obviously he's calling with draws and hopefully folding 77-88.
