You definitely need to use this program in those rooms where it is allowed, and where it is not allowed, the program simply will not work even if you have GG Poker and PS running at the same time as H2N
It is definitely allowed on the following rooms: PS / PS.es,
888 Poker, WPN (AmericanCardRoom / Pokeking), Winamax.fr.
As for the HUD itself, the simplest standard HUD with the following parameters will suffice for a beginner: VPiP (total percentage of hands played (when the player put chips in the pot in any way)) / PfR (preflop raise - the percentage of how often the player entered the pot with an aggressive action (raise) ) / 3Bet (it is clear here) / Hands (the number of played hands of the opponent (Always pay ATTENTION! because the fewer hands, the greater the probability of incorrectly determining the style of the opponent, and vice versa, the more hands, the better I understand how to play against a particular player)) and Nickname (sometimes there may be a crash or accidental movement of the HUD manually and the numbers will show on the other player and you will play against him incorrectly)
What is it for? Well, first of all, to make color notes. For faster decision-making (especially when playing many tables) and in order not to follow the players yourself using this wonderful tool. It is pointless not to use it where others use it. It's like competing on wooden skis in the 21st century
This program is free and even for a person who plays on ABI100, a free one will be enough. As for HUD, there are many of them, both paid and free. Search Discord servers for poker schools or streamers who make free HUDs. But think about whether you really need such an extended HUD with a huge number of numbers and Pop-Ups (probably another unknown word for you that means a HUD with a HUD in which several more HUDs
) which you most likely do not understand? I think not. Get used to the standard because everything big starts small
Is this program easy to use? Yes and no. The hardest part is getting started. And then everything is very simple and the game itself becomes easier because it does many things for you. Do not forget that there are a lot of useful functions even without a HUD. You can watch a replay of any hand you played and the hands you marked (the ones you thought were expensive or where you got out or where you have doubts about whether you played correctly or not). Many filters by positions, stack sizes and late stages of the tournament (there is a lot to work with). Also, do not forget that you also automatically collect statistics for yourself and after you have collected at least 50-100k (the more the better) hands on yourself, you will be able to contact a trainer who will analyze your base and point out your main mistakes
Well, a lot of text (although I could have written much more)
This is what a simple HUD looks like for a beginner and it will be enough!
