River folds are cool atm.

[Benman]

Oops, you're right, it wasn't really a donk. OK, I'm amending my new rule:

If I choose to raise the river for value against a single betting opponent, I will never fold for one additional bet no matter how grim it looks if I am getting better than 8 to 1.

This rule is certainly more questionable than the rule you stated in a post yesterday that you don't bet / fold the river, but I still like it. If it's not neutral or slightly positive ev at the time, it will be for picking off/discouraging bluffs.
