Assuming you know near perfect BS, and are not counting cards:
If you have $ 10,000 and bet it all on one decision, you have about a 48% chance of doubling your money.
If you took the same amount and made 1,000 $10 bets, your chances of doubling your money would be far,far lower.
On the other hand, betting it all on one hand means you"ll go broke more than half the time, while spreading it over 1,000 hands reduces your chances of going broke to almost nothing.
So, is your goal to double your stake or to preserve your bankroll?
