Dynamical value of the hand.

The one thing that everyone forgets is that even when you draw to your "outs" you should undervalue making your hand (hand odds) slightly due to:

Your "outs" are not really "outs" because you are already beat and cannot win if you hit.

some of your outs are also your opponents outs with a better hand

some of your outs are your opponents outs with the same hand (split pot)

An example would be if you were on an nut flush draw and your opponent has two pair, your cards can give you your flush but can fill your opponent.
Just because you hit your cards, your opponents can hit theirs too. So just becasue your getting correct odds hand vs pot, to call you probably shouldent unless you are getting slightly better pot odds or you can confidently put your opponents on their hand.
