Context: Tool what-is: bankroll
Bankroll Management determines how many buy-in swings you can withstand without going broke. Common advice: 20–40 buy-ins for cash games, 100+ buy-ins for MTTs. A single session stop-loss of around 3 buy-ins helps control tilt and daily variance.
Context: Tool guide: bankroll
Bankroll Management (BRM): Buy-in multiplier × stake ≤ total affordable bankroll. Cash games typically require 20–40 buy-ins; MTTs due to higher variance often need 100+ buy-ins. Long-term EV, ROI, rakeback, and orbit-cost jointly determine real hourly rate; stake selection should keep variance within psychological and bankroll tolerance. Use the calculator on this page to instantly compute break-even win rate, then cross-check the numbers against opponent ranges, position, and turn/river plans to avoid memorizing formulas without applying them at the table.
Moving up in stakes after a loss to chase; declaring +EV or dismissing skill with insufficient sample size. Ignoring rakeback makes marginal strategies actually negative. Using recreational funds at professional stakes; variance breaks BRM. Also, don't treat Solver frequencies as infallible without pot odds verification; when information is incomplete, ICM and SPR remain the first principles of tournaments.
Record buy-ins, stakes, duration, and ROI by game type. Cross-check against variance and tournament ROI; adjust stakes only with sufficient sample. Write down move-up/move-down trigger conditions; they matter more for long-term survival than single-hand technique. Each week, pick five real hand histories to recalculate using the same tool, and revisit the glossary to review concepts like pot odds, ICM, SPR which are auto-linked.
Scenario：NL50 single table buy-in $50, choose 30 buy-in rule.
Conclusion：$1,500 can stably play NL50; strictly implement stop-loss.
Scenario：NL25 lost 5 buy-ins in a row, want to move up to NL50 to recover.
Conclusion：After consecutive losses, raising bets violates BRM; lowering bets or taking a break is a better choice.
