heads up, i suck.

[squire]

i generally play the $11s at party, just got past my 1st 500. i have an ITM of 44% and roi of 20% my problem is with heads up my 1st 10%, 2nd 17%, 3rd 17%. i am usually quite aggresive from level 4 onwards, as per advice on this forum.
do you guys have specific calling ranges for different types of players hu?
i usaully open raise 3-4Xbb with top 60% of hands and fold to a re raise with anything but premium holdings, occaisionally just pushing to mix it up. i only ever smooth call with a real hand.
any advice? are my 1st too low.
thanks
