At the moment I am trying to learn about hand range, but I think it is impossible at this level, I can never guess what they are holding...

How do you know if you suck at poker or if it is just variance, when you are new the game and are not sure if you are playing correctly?

Do you just fold and only bet the nuts, or how do I do this...?

My stats are 17/10/3, but am only breaking even... Do I thigthen up even more, or what do I do?
