Lol que?
Good positional awareness is a good thiing, not a leak. What do you mean by high...
If you're not positionally aware, a common rookie error, its a huge leak. If you have aj or a10 utg..you don't want to raise much or, depending on the tabe/situation, its a fold (because with so many ppl after u its pretty likely someone has u beat). If you're n the button and everyone before you folded..aj is now a strong hand lol.
