How does fold equity change as the street are played out? In particular I'm asking here about fold equity when you go all-in.
There seems to be two ways of looking at it.
On the one hand fold equity goes up with each street because Villain has less and less chance to complete his draw.
On the other hand, fold equity might be going down because perhaps he has improved his hand. Or is it Villain dependent (which seems to me to be a bit of a cop out answer)?
At what point is fold equity at its lowest? Preflop, or after the flop?
