Choose such a limit to take on the table no more than 10% of your capital, unless of course you plan to make a deposit soon or start again with
freerolls.
At first, I recommend to go to the table with a stack no more than 50BB. The fact that in poker is much easier to lose than to win, especially a lot to lose, than a lot to win. Is it bad if you win 50BB. There is one more aspect - when you have less stack than your opponents, they are often not afraid of you and play more relaxed than if you had an equal stack with them. This you can successfully use, collecting a good hand.
