I see FE (fold equity) referred to many times in these posts. I have a foggy notion as to what it is, but it is not in "super System by Doyle Brunson, nor in "PLay Poker Like a Pro" by Phil Hellmuth, nor in "The Theory of Poker" by Sklansky; (aren't i learned). lol
Seriously, a little discussion here on this would probably serve many players well. (like me)
