I dont really use any hud except jivaro. Unless there's a way to tell.
I think you should use a tracker if you're planning on taking poker seriously. Even if you don't use it for the HUD its good way to tell if you're getting lucky or if you're playing well. And when you have downswings its a good way to find out why you're having downswings. As well as track how much you've won and lost.
The reason I ask is because if it took you less than 20,000 hands to earn 25$ then you're probably on a heater. I think you should download a tracker like pokertracker or Holdem manager and see what your profit looks like over 10,000 hands, and if you see fairly consistent profit over that time period and you have the proper
bankroll at that point, then move up.
I say this because my first week of
online poker (like 3 weeks ago) poker I won 15bb and thought I was doing great. The next week, I lost 25bb and busted out. I wouldn't have known why I lost so much if I didn't have poker tracker and the great advice here. Point of the story is that I thought the first 15bb was skill not luck and the 25 I lost I thought was bad luck and not lack of skill. In reality the 15 I won was luck and the 25 I lost was lack of skill.
I'm not saying that's the case with you, but its good to know and I think you should stay at 2nl until you know, just my opinion. Some extra opinions on this from more experienced members would be really helpful.
