BRM
BRM is short for bankroll management.
The simple explanation
BRM is short for bankroll management. It means matching the stakes you play to the amount of money you have set aside for poker, so that a bad run cannot ruin you. Players say 'good BRM' when they play within their means and 'bad BRM' when they take too much risk.
A closer look
A sound plan sets a number of buy-ins for each stake, such as 30 to 50 for cash games or more for tournaments, and rules for moving up and down. Variance means even good players can lose many buy-ins in a row, so a bankroll must cover swings. BRM is a form of risk control: it does not make you win, but it keeps you in the game long enough for your skill to show.
A practical example
A player has 30 buy-ins for their stake, then drops down after losing a third of their bankroll. They are following BRM rules.
Full explanation
BRM is short for bankroll management.
BRM is an abbreviation of bankroll management. It is the practice of playing at stakes you can afford based on the amount of money you have set aside for poker.
Without it, a short losing streak can wipe out your funds. With it, you have enough buy-ins to survive downswings and keep playing.
Typical rules say how many buy-ins you should have for a stake, when to move up, and when to move down.
The term is mostly used in poker forums and chat, and it is the shortened form of the longer phrase.
