well, in the thread i looked at people weren't agreeing on a water tight deffinition but that's ok.
I think fold equity is taking into account all the factors that would lead someone to fold.
I had a hand recently and there were SO many outs, i'd still kinda missed but i bet a reasonable amount on the turn. Hence I had a lot of fold equity in my play (or how do i word it.... the other player has fold equity? or i do?) and they folded.
Is that about right?
