PAHUD ???
 

I just got a new laptop a week ago and I guess Pokertracker is down so I can't use PAHUD. I plan on switching back to my old computer or figuring out how to get PT on here relatively soon and I have some questions regarding HU play as I am relatively new and have never analyzed stats for HU.

A) What are aggressive stats?
B) What are passive stats?
C) What is/are the most important stat(s)?
D) Are there any indicating stats that reveal weakness?

Your input would be greatly appreciated. Its difficult right now but I feel a great learning experience not using it in the beginning of my first 10kish hands, but I def want to start using it soon.
