Bankroll management is one of the most important thing to along life in poker.With out good rules or guidelines you will go bust.
Limit Hold'em bankroll rules
First off I will start with limit. Your bankroll should 300 BB. so let say you are playing .50/$1 limits. The amount in your bankroll should be $300.Now to move in limits you should have 300-400 BB of the limit that you are moving into. As you play downswing will come into your game. To protect your bankroll move down in limits. a good guide line for this is if your bankroll goes down 200 BB for the limit that you are playing.
Tournament guide lines
75 buy-ins is a good bankroll. Say tournaments are $1.10 to get into. Your bankroll should be around $83. You can move up in tournament buy-ins when the bankroll is hits 100 buy-ins of the next levels. so If you are playing in $1.10 tournaments and your Bankroll gets to $175-$220 move up to $2.20 buy-ins .Now if you go below 50 buy-ins drop down and play in cheaper tournaments.
Will post laterNow having a bankroll with good rules/guide lines means nothing if you keep losing it.You know you are in the right limits if you are pulling in around 1 or 2BB/Hr in live games and about 3or4 BB/hr in On-line games. As for tournament play you should be getting double your investment. will add more after..... Good luck for now
