How should I have played this differently?

First of all, reads would be nice.

After everyone folds to UTG's flop bet, I'm not really sure a checkraise is the best play here. I realize the BB is still in there but it's not really a big deal. I would consider calling the flop and betting out on the turn.

Your turn play is inconsistent with your flop checkraise. If you thought you were ahead enough of the time to checkraise the flop then you should bet out again. You're missing value from worse 8's and lower pocket pairs. Also, if UTG happens to be capable of folding TT/99, he won't do it if you check. I'd bet the turn.

River is fine considering the weird way you played it.
