Learned it over the weekend and it shows promise. Let me know,please.
The idea is to break your session into sub-sessions,that I call innings.The object is to either win 1 chip or break even every inning.
You start with a $5 bet. If you win,thats it, Inning over.Bank the chip.
If you lose the first bet,you double your bet and now have 2 units on your 2nd bet. If you win,you are up 1 unit for the inning,and it is over.Bank the chip.
Now,if you have lost both bets,you keep the 3rd bet at 2 units. Should you lose,you continue betting 2 chips until you win. goes like this
1st bet-1 L(-1)
2nd bet-2 L(-3)
3rd bet-2 L(-5)
4th bet-2 W(-3)Now we raise the bet 1 unit on the win.
5th bet-3 L(-6)
6th bet-3 W(-3)We don't raise because a 3 unit win next round will cause us to break even.
7th bet-3 IF you win,you start a new inning with a single chip.IF you lose,you arecontinue betting 3 until your next win.

I've used similar systems. the only draw back is the table limits if you keep doubling. Try using your strategy on the dozen areas. your return is more if you miss more consecutively. Do you know of any online roulette systems that do not have limits? or have higher limits than $200-$500?
