Easy call on the river given pot odds (10:1). BB special can be T9s, AJo, JTs, QT, or whatever else junk mr WPT expert thinks is money.

While most of the time J8s or Jx jank will show up, the turn check throws smells fishy. He knows you have an overpair, and if he is trying to set you up for the turn CR, he played the flop incorrectly.

Regardless, with the pot that inflated and blanks hitting both the turn and river, I think it would be wrong to fold for 1BB.
