Here's a
bankroll tip:
DONT RISK IT ALL ON ONE TOURNAMENT OR ONE CASH TABLE!!!!
To play limit cash games you want to have at least 200-300 big bets, so if you wanted to play .05/.10 limit hold'em for example you would want $20-$30 in your bankroll. Then the reccomended buy-in at each table you play is 25 big bets (in the .05/.10 example: $2.50)
To play NL cash games, you want to buy in for the maximum at the table (usually 100x the big blind). So if you were to play .05/.10 NL hold'em you would want to buy in for the maximum of $10 every time. A good bankroll is 20 buy-ins, or in this case $200.
To play SNGs (especially at the lower limit) you want to have a bankroll of 30 buy-ins. So if you were playing $5+$1 ($6 total) SNGs, you would want a bankroll of around $180.
You don't want multitable tournament buy-ins to take up too much of your bankroll, so try and keep the average tournament buy-in to 1-5% of you total bankroll.
If you follow these guidelines and you are at least a semi-decent player, you will find that your bankroll will last longer and grow. It might seem to take too long at first, but you will be suprised on how fast it grows...
