THe point is being missed here. The question isn't why are bad beats so costly to one's bankroll because if they were costly to one's bankroll, then one wouldn't be rolled properly for the stakes.

The question is, why does one or two bad beats destroy 2/3 of the income that took two hours to grind up? It's so frustrating when you spend two hours in tedium grinding away at 6 tables, taking down small pots, getting closer and closer to the nearest benchmark, only to have almost all of that work done for nothing because some lucky idiot hit a full house with 69o when you hit your flush.

That is the question. And it isn't that some bad beats do that.. it's that almost ALL bad beats do that! Is there a trick to make these bad beats less costly so it doesn't destroy one's motivation to keep grinding in the cash games?
