I´m more concerned about how position effects post-flop play.
There is two problems with the hot and cold equity preflop paranoia that is flooding this forum.

1.Hot and cold equity is measuring hand values when the hand is played to showdown.But hands are not played perfectly post-flop according to their actual equity since the information about the other players hands are concealed.Pots are constantly being taken down by hands that had less equity than other hands.And many hands are laid down by players that had enough equity to proceed.

2.The equity does not measure how many bets you win when you have the best hand or how many bets that goes in the pot when you have a losing hand.It just estimates how many times your hand is going to win against another hand (and it can´t even estimate that correctly as you can see in 1.)not which hand is going to win the most money.

Both problems are related to implied odds.And IMO your choice of preflop action and/or the way you intend to play the hand <u>when you´ve decided to play the hand </u> strongly effects your implied odds.
And in turn your choice of preflop action and your post-flop plan should be strongly effected by your position and implied odds instead of hot and cold equity alone.

It is my strong belief that you can have a decent equity edge preflop and that you can have two different outcomes (one where you lose money and one where you win money)depending on whether you raise or call preflop.
This phenomena is also IMO strongly linked to position. Generally speaking (if we are table selecting well) I think that a more passive approach preflop when OOP enhances our Implied odds and that a more aggressive approach in position enhances our implied odds.
The key to profitable poker IMO is to know what action that gives you maximum EV combining raw preflop equity value with implied odds value.
I´m probably wrong but I´m not yet totally convinced that the "2+2 way" of playing certain hands against certain villains gives the optimal EV.
In this case I´m however totally certain that raising preflop gives optimally EV.

As said in my answer to Oink.By equity edge I didn´t mean hot and cold equity.I meant overall equity including implied odds.I didn´t realize that this equity term was a product of my own brain and that the term really didnt exist outside it.
