Hello brother
Well, I will try to explain to you, based on what I have learned to increase my bankroll, how you can try to be a "regular player" in poker.
First, you must keep in mind that to be a regular player, you must have enough time to dedicate yourself to poker. This involves daily study, practice, hand review with solvers, etc.
That is, you must have a daily routine, in which only in that time that you dedicate will you only submit to the game and its derivatives.
Afterwards you must be very clear about which modality you will choose to support yourself in the game. If you choose cash, either tournaments or sit go, and what type of game: Hold em, Omaha, etc.
Once you are very clear about this, you must understand bankroll management, and above all you must understand downswings or bad streaks very well.
Bankroll management is very important, even more so if you deposit to create this bankroll management.
In cash, for the deposit you will make, the most that will be possible for you is to play NL5, that is, cash tables of US$5, although it would be advisable that you start playing NL2 tables, that is, cash tables of US$2.
What experienced players recommend is that your bankroll be equal to 100 boxes. That is, if you deposit US$200 divided by 100, it would give you to buy 100 boxes of US$2.
This is mainly due to variance. So on with a table of values.
NL2 bankroll u$s 200
NL5 bankroll u$s 500
NL10 bankroll u$s 1000
and so on.
This more than anything is explained by the game itself. For example, I'll tell you about an experience of mine. When I started playing NL5 I had a very important downswing on the first day alone. Between coolers and badbeats I had a loss of 12 boxes or $60.
In this case I took into account that it was not the same to lose without problems, that it is normal to lose 12 boxes in NL2 than in NL5, that is, by living that experience I automatically returned to NL2, and today I am already incurring NL5 again.
In other words, it is very important with humility, to know how to understand that you can go down a level without problems and then go up when you are ready again.
You should also understand that a good cash player wins on average 7 BB every 100
hands. If one considers that a fairly regular player plays about 3000 hands per day, the sum will give you that you can win an average of about 200 BB per day or 2 boxes in any modality.
That is, to win US$2,000 a month, you should be playing at least NL50, and being a winning player you could earn about US$3,000 a month or exceed what you want, which is US$2,000.
As for the tournaments, here the variance is greater.
If you deposit US$200 you will not be able to play tournaments greater than US$2.20 and as a limit you can play a tournament of US$3.30 or very occasionally a tournament that you consider important of US$5.50 . Not many more than that.
If you consider that a tournament of US$2.20 at most can pay around US$300 for 1st place, and that in fact you very rarely reach that place, it is necessary to understand that it is much more difficult to increase your bankroll .
That is why to increase the bankroll in tournaments it is essential to enter the ITM minimally, but sometimes you also have to take into account that before the ITM you will have hands that you will often play no matter what and you will not always be lucky enough to win them.
A regular tournament player generally enters the 20% of the ITMs, in that percentage we must try to achieve the first places, which are the ones that pay the most.
The final conclusion is: Today, to achieve that goal of US$2,000 per month, you should understand that your bankroll should be at least US$5,000, and that you be a winning and profitable player.
That is my position brother regarding your question and about my experience of the exciting game that unites us.
A big hug, and I hope you can obtain the achievement you long for.
