This is similar to an old blackjack scheme, "1-1-1, 2-3-4-5-6"...
Any time you lose, go back to step one.
Bet $1 on a hand (assuming the table minimum is $1, if it is higher then use multiples for all these bets). If you win, bet another $1 on the next hand, then another $1, etc.
When you win 3 hands in a row, increase your bet to $2. Since you are up $3 at that point, you are only gambling with won money. If you lose $2, you are still up a buck.
If you win that hand, increase to $3, then $4, then $5, then $6. If your table is a $5 minimum your bets would be 5-5-5 then 10-15-20-25-30. When you get to the top bet just keep repeating it, as your chances of losing get pretty high at that point.
This sort of scheme takes advantage of runs of wins that happen occasionally and basically decrease your chance of losing all your stake very quickly. So you can hang around the tables drinking for free and earning rewards points for a longer time, assuming you have a reasonable level of playing skill. I don't play tables myself so I don't know how casinos feel about this system, heheh.
