you are not betting out a better hand very often here, and you have an 8, no kicker. A8, any heart, two pair, etc. beats you and will probably not fold. Still, it might make sense to bet the turn, fold to a checkraise, and check through the river if called.

Alternately, you could check the turn, check/fold the river. This is a tough line though, given vilain's aggressive profile, because he wil probably bet the river, so you're basically giving up on the hand. Still, the 5.5 BB in the pot probably don't justify a river call.

This seems to me like a bet the turn when you're probably way behind situation.
