re: Poker & Explain the 1 bb per 100 hands
1 BB / 100 or 1 BB / Hour is a pretty conservative estimate for a decent player... in some of the poker pros books 2-3 BB / hour is listed as standard, which is a lot more than 1 BB / 100 hands. It depends on the table and your level of ability, though, naturally.
It's not about whether you're taking gambles or not - it's about average results. Some periods you'll have a run of good cards/luck, some periods you'll have bad cards and bad beats - in a short period you can easily get lucky and make 20 BB / hour, but you have to balance that against the bad sessions to see where you end up. Poker Tracker and other stats programs help with this as they allow you to automatically calculate your BB/hour stats - the most important thing obviously being to make sure it's positive.
