I haven't played running it twice but it looked like there was still importance to secrecy before the second river was flipped given the way they were acting.
> The play on the turn is way too ridiculous
Assuming the cheater doesn't know the deck (which would be extremely hard to pull off). How is cheating in this case logical? She had the losing hand at the time she called by a few percentage points.
Sometimes you call bluffs with a face card figuring it will win. It isn't a good bet but it isn't a terrible one as this hand shows.
Also insinuating that no one would return money when threatened is weird.
