Ok... lets say we flop the nuts (or substantially stronger than your op)

do you usually overbet (allin?) or valuebet (hoping that a weaker hand will just pay you off?)

does that depend on which street? what about on the river?

does that depend on position? how many players?

I think a big leak in my game is I don't get enough value out of my nuts, because I'm speculating that my op's hand is not nearly 2nd nuts and won't pay me off unless I bet a reasonable amount.

Thoughts?
