For you to reach the opening level of 4 tables at the same time, you will have to train a lot my friend, 1 table already I find it difficult to imagine 4.
I believe it is not easy to achieve, but with faith focus training every day, we got there one hour.
Luck at the tables!
The pleasure of doing good is greater than receiving it.
Start playing 1-2 tables. When you feel confident and regularly win money, you can add one table, then another. Do not rush to play many tables at once. Winning at 2 tables is better than losing at 4 tables. Poker tracker helps keep track of opponents.
Why do you want to play more than 4 tables? The typical answer is, you want to increase your hourly winrate. But you are not a professional player, so why does your hourly winrate even matter? And even more importantly you can probably increase your hourly winrate more by moving up than by adding more tables. Judging from your posts you are currently playing 5NL cash games, so instead of adding more tables simply move on to 10NL cash games.
Mass multi tabling makes you a worse player, because you are forced to make most decisions on autopilot, and you miss out on a lot of details. Moving up on the other hand expose you to better players and force you to develop your own game. There is no future in being a mass multi tabling 5NL grinder, so dont fall into that trap, as so many others have. Focus on quality rather than quantity.
