I don't understand how betting rivers like this is profitable over the long run. It seems to me the only time to bet these rivers is when you're bluffing and will fold to a raise.

Check-calling seems like the best way to avoid losing 2 bets, possibly induce a bluff that you'll pick off and avoid a terrible fold that costs you the pot.

FWIW - I've won way more than I've lost calling when it looks like someone is making Clark's bet when the board flushes. I'm guessing it's become the worst kept secret.
