I have dabbled with Parleys, I found them utterly frustrating, to win a bet then give back that profit due to losing the next bet. Ditto part parleys, or reverse Martingale, Contra D'Alembert (the latter two I have never used).
I've used deep negative progressions, which are not for everybody, depends on your personality and risk aversion.
After many years of playing this game, you have to break it down to the basics, especially after being wiped out!!
Identify the issue, you lost your bankroll because of what? Because you chose the wrong side to bet? What can you do about that? In reality NOTHING, the game is what it is...
So what happens when you lose 4 or more, win a single bet, lose 4 or 5, win a single bet, and lose another 4 or 5. It happens, if you played another way, it fixes that shoe, but breaks another. This what the game is.
All negative progressions that you find on the internet have the player betting too much in these or similar situations. For example, the Fibonacci, The D'Alembert, Z-method, Labouchere, 31 system, 2-5 system, Martingale and the list goes on and on.
When you accept that there is little you can do about avoiding more losses than winners, you need IMO to design a betting option that can withstand such runs. There are two ways to handle these, one I will share, the other is propriety.
One which should be commonly know is STAR, basically a series of flat bets, followed by a Fibonacci, however it could be followed by a Labouchere, also the pre-progression stage could be extended to whatever you like. You can read all about STAR and it's variations on the GamblersGlen site (this site has malware, which doesn't bother me, I scan my PC afterwards). In the Baccarat section there is a thread called "The Sequel to Elongated Star, the mildest progression you will ever need".
I will post the contents, in another post.
I decided after reading everything there is about progressions, that some late century mathematician shouldn't be telling me what to do with my money, that after X losses I need to x amount.
So I designed my own, based loosely on a series of Labouchere's which IMO is the most manipulable betting option, I'm sure VLS will agree, as he once said the exact same thing. Quote, Don't let a single losing run consume your bankroll. How I do things, is personal, yes it is a grind, but generally safe.
Just returning to this STAR option. Here is a consideration for the board.
Grab a bunch of the most choppy shoes you have.
Take a stack of 10 low value chips (table minimum!) say $5 or $10, play the shoes out betting FLD (follow the last), anytime your 10U chip stack goes beyond 10u, place any excess into your other pile of chips.
Because you chose "choppy" shoes, you should lose all of your 10 stack ($50 or $100).
Now you switch to betting either, $25, $50 or $100 per hand to recoup plus add in a profit, and see w hard it is to bust your bankroll.
You have two options to recoup, a Fibonacci or a Labouchere (Labby)
So if you bet $5 initially, you could write 1-1-1 and use a Labby valued at $25, or write 1-1-1-1.
$10, write 1-1-1-1-1-1, or simply use a Fibonacci with a goal target of winning 6 units, or even 3 units if you switch to betting $50 per hand, or 1 unit of you switch to betting $100 chips. I deliberately said chose choppy shoes, because choppy shoes don't stay choppy.
You have lots of options, Labby v's Fibo, $25, $50, $100, but do include profit. BTW, as you initial 10 chip stack goes up and down, you'll die of boredom, maybe. But it's better than losing, no need to think about, "what side do I bet next", just plough straight though the shoe, not all shoes be like this, so you will make money. The same could be applied to the bet selection DBL. When it comes to YOUR money at the table, you want options, not blindly following some paper you read on the internet..
