Hey guys, 

 I started to play poker, just for fun 2 years go, and what i play most of the time is tournaments, micro stakes, and couple of shots on medium stakes .

Ive been doing just for about 8 months with more professionalism, and making some nice scores which had let me to live of this, I have seen that almost everyone uses Holdem manager for their stats, but i downloaded the free trial, and seriously could not understand anything, my native language its not english, but even though i look for info to see what meant every little abbreviation, is just that i dont see where to start, and even knowing what is each number on the HUD, ( by the way what does HUD stands for?) i dont see how to interpret those statistics.

I dont see any basic tutorial on HU official page or in the search that i have made, do you think that theres need to pay someone to give me a basic course ,or is there any blog/forum you know that can help me, from the very basic things.

My other question is , does a person who only plays tournaments really need this? or is more for cash players?

Thanks-
