A general rule is 30-50 betting units for a comfortable session. For a 4-hour session at $25/hand, you'd want $750-$1,250. The exact amount depends on your risk tolerance and how long you plan to play.
With proper bankroll management (30+ units), your risk of tapping out in a typical session is under 5%. Shorter sessions with 50+ units have very low risk. The variance calculator helps quantify your specific risk.
No. Only bring your session bankroll - the amount calculated for that specific session. Keep your overall bankroll separate. This prevents emotional decisions and ensures you have funds for future sessions.
Longer sessions require proportionally more bankroll because variance compounds over time. A 4-hour session needs roughly 1.4x the bankroll of a 2-hour session, not 2x, because standard deviation grows with the square root of hands.
