Are there any resources or suggestions on minimum BR required for a session, given stakes one plays? For example, if I play a 6 deck, $10 minimum table, with a max bet of $100, how much should I have in my pocket to survive swings? What about for a $25 DD game with a $200 max bet?

Similarly, if taking a trip where one intends playing 25 hours of BJ (say a 3 day trip), max bets as above, what should the trip bankroll be?

Finally, at what point do you quit if losing? I have noticed that sometimes, I played till I had under a $100 and then it seemed that the last $100 would be ground out.

In effect, how much to take and when to quit?
