Thanks KoolMoe ... my intended question (I didn't articulate it well) was:

What's the difference between fold equity and pot equity edge?

I think you answer was: 'they are the same thing'; *fold equity* is just another term for *pot* equity edge.

e.g. say you are a 3:1 dog to win a pot, but there are still 5 people in the hand. You will win more than your fair share; you win all the $$ in pot 1 outta 4 times, and yet you and 4 other people are still contributing new $$ to the pot. 25% of the time you win the pot, but you are only contributing 20% of the new $$ going in ... You have a pot equity edge of 5%, so pump 'er up!!!!!
