Thanks for being sincere and assuming your weakness to us. I recommend you open just one single table at a time until you get very profitable.
When you start to make more than 5 BB/ 100 BB per hour played, you can think about opening a second table.
For lower limits I would recommend a winrate of 10 BB/100 BB, cause the rake structure is heaviest.
Players who are able to play in 4, 8, 16 tables are solid regulars who have been playing for a long time, they are poker Grand Masters!
Assume your own level and capacity, first know yourself and your capabilities and don’t be shy, just continue studying and someday you will achieve the ability to play several tables at once.
I like to compare it to chess: only a few chess Grand Master can beat a lot of players/tables, and to get there is required many years of solid discipline and study.
Don’t be in a hush, for what is the point of opening more tables to have less success/a minimum winrate? Isn’t much better to have a winrate or 15 BB/100 BB playing just one table than having a poor winrate of 3 BB/100 BB playing 4 tables?
For instance, if we are playing 6-MAX tables we are paying the blinds 1 out of 3 hands played and we are facing 5 opponents at once. If we open just another table we are paying more blinds against 10 opponents! Do you see the difference? And all of this out of consideration for the rake structure.
Be calm, patient and let the chips fall as they may!
The greatest kings of this world were humble and simple people, follow their lead!
Thanks a lot for your contribution, have a nice day.
