JJ Overpair, donked in river

Villain is 40/15. I had no idea how to interpret the line but i gave it a crying call in case he had a busted draw and tried some silly desperation bluff

I'd fold river.

^ as above ^

wat i call and villain shows AsTs

how is this ever a fold against a donk random

call river as played.

bet more on flop and turn though.

def call, people who are saying fold are just being results orientated because obv op wouldn't have posted if he'd won.

you need to win 25% of the time or better. He has A9/AT/9T a bunch.
Calling is fine.
Bet more on turn.
