Also an intro post for me, also a new member and thought I'd let you know what I have read so far and seems to be working for me. This is a long reply, so I hope you have some coffee .
Bankroll Management (BRM) is the way you manage the amount of money you have in your poker "Bank Account".
There are a lot of opinions regarding how you should manage your cash, but I'll give you the general overview.
Cash Games: When playing cash games you will find that you will be grinding and going up and down quite a bit, in the beginning, I would go with a Max of 5% or your Bankroll daily. This means if you lose 5% of your roll ($10 if your Bankroll is $200), STOP playing for the day, switch to play money, or better yet, come and read CC, whatever it takes... But stick to it. Once you are winning consistently, move it up to 10% but never past 10%. At 5%, you can lose for 20 days in a row before you go bust. You should also stick to the micro limit games, your 5% should be at least 100 times the Big Blind of your desired stakes. (e.g. If you have $10 per day, your Big Blind should be 10c on the table that you are playing)
Tournaments: Although your wins will be bigger with tournaments, you will lose more often than winning, and you will need to ensure your Bankroll can support these huge gaps between payouts. I would recommend that you go with 4 times the buy-in of the tournament times 40. This means if you have $200, you should be entering $1 tournaments and Freerolls
I know this sounds like an incredibly small amount, and you will start off slow... But, this will account for any massive downswings, as well as allowing you to forget about the cash. This helps a lot with your mind set, as you will not be in constant fear of going bust. Learn how the game works on the net, and for real money
, as each of these brings new aspects to your game.
Have fun and try and be as disciplined with your Bankroll as possible, if you lose for more than 5 days in a row, take a break. And read as much as you can...
That's all I have, enjoy and see you on the e-felt.
Edited to add; Also, I would recommend staying away from Rush, and even No Limit all together in the beginning, both will bring massive swings for the beginner.
