Fold. IMO, one of them was chasing the diamond. It's not a coincidence that BB wakes up with a huge bet at the end after being passive the entire hand once the diamond card comes.

A call here would be terrible, BTN still is yet to act.

BTN only has $9 left. I'm having trouble with a range here. Surely it must be wider than just a flush?
