$10/$20 Plays itself or I donked it up?

it would be a hilarious fold for sure... even better a fold and show. If I know he has the flush should I fold? That's my real question.

I mean I appear to be getting it in here with a monster but in fact it's a losing push longterm right (vs a known flush)?

If I fold I still have 40+ BB or so.
