Dynamical value of the hand.

...because I don't really think his question HAS an answer, so to speak...

If I interpret what he's asking about correctly, then the "calculation" changes from moment to moment, as one puts his opponents "on" a hand...essentially the calculation is "my opponent(s) have XX, so he/they have X number of outs, so my bet/raise does X to that player's pot odds for that particular hand or draw". So if I have my opponent on a river-card draw for a flush that would beat me, I know I need to keep the pot odds at less than 5 or (at best) 6 to 1 or so or I'm likely to get called, and possibly beaten. But that calculation changes from card to card, from player to player, from moment to moment...hence, the "dynamic" part.

Now perhaps I've misinterpreted the question...but that's my take on what he's asking.
