that's enough from everyone

If you two could just try to avoid each other you'd be saving me a lot of grief. Thanks.

As for your post, plain and simple equity is the % of the time a player should expect to win a pot once all 5-cards are dealt. Programs like pokerstove help us to solve very complex cases but if you want to understand how to do it yourself it's quite simple. All you need to know is an estimation of the number of outs (cards that win you the hand) versus cards (non-outs) that do not. Once you know this it's quite a simple mathematical equation where equity= (#of outs) / (total number of unseen cards). This would be with one street left. With two it's slightly more complex, but it would be:

[1-(chance to hit the turn)*(chance to hit the river)]*[100]
