re: Poker & Cash Out
How much are you buying in for? If you're buying in for your whole BR (which would be a single 100bb buy in), wait until you're completely on your best game, find the best possible table conditions, and leave as soon as you double up (i.e., rathole). Then find the best possible table conditions and buy in for half your BR, rinse and repeat until you've got enough of a BR to not rathole.
I'd guess, though, that you're prob buying in for 25% - 50% of your roll? I'd still suggest ratholing when you double up fwiw. I'd suggest doing this if you're not (i.e., don't put your whole BR on the table).
Normally I completely agree w Mase above, but not when your BR is a single 100bb BI.
