I've never played higher (well, I've played like 2 hours of 3/6) so I can't tell you when I'd start to give unknowns the credit for thinking about what you're having them think about, but I wouldn't do it at 2/4.

You've got to have the winner at least 6% of the time because at least that often the river raise if some goof who is excited that they have 2 pair now.
