In addition to information it more importantly provides you with more options to make plays, get value and the ability to pot control / control the action. As such we should be okay playing out of positon against opponents who won't use position to make our life difficult and just play their hand.
We don't want to be out of position against a skilled player who will put us in lots of difficult spots. An example of this is when a really aggressive player is sitting to our immediate left it really affects our game and we need to make the appropriate adjustments to remain +EV, yet when he's sitting to our immediate right we're +EV nearly right off the bat.
Which kinda reminds me of the A2o open UTG that someone mentioned. If we have two nits to our left, a fish on the button, and two nits in the blinds we can profitably open if the fish does not use his position, will pay off easily with worse hands and makes his better hands clear to you by raising or jamming.
So positional awerness is very important for your strategy at the table I should think.
Positional awareness is basically the knowledge of what flexibility positions gives in terms of range construction which affects the EV of your line. It affects your decision on every street and not just preflop.
When you can answer Improva's question then you will see how you can exploit people who are not positionally aware.
