In roulette circles Jean le Rond d´Alembert (1717-1783) is associated with "Progression d´Alembert": One step up after losing and one step down after winning. A few examples: -1-2-3+4+3+2 = 3. And 1+1+1-1-2-3 = -3. The player  from the Age of Enlightenment might be balanced. And Red and Black might be in balance. But this balance is not reflected in the last example! 
"Contre d´Alembert" is contrary to progression d´Alembert. One step up after winning and one step down after losing.  I do not think, that this is worth trying on Even Chances.
I rather try it in a flexible way on the known DS: 1.  1-6
                                                                  2.  7-12
                                                                  3. 13-18
                                                                  4. 19-24
                                                                  5. 25-30
                                                                  6. 31-36.
I bet the groups that came IN THE LATEST FOUR SPINS. The average is jut a little bit more than three groups. Within four sessions I once bet only one group.  63 X two DS, 159 X three BS, and 68 X four DS. In average one session lasted appox. 76 spins.
The session ends when I have won on a DS on LEVEL 10. My first four sessions (from the first four days of 2011, table 3, Spielbank Wiesbaden) resulted in 181+87+27+80 = 375.  375 chips or units.
After a [smiley]aes/coffee.png[/smiley] break I´ll show you how  I start one session

[smiley]aes/coffee.png[/smiley] Keep an eye on the latest four spins!

13
29
20...One chip on DS 1, 3, 5, 4.
20...Hit! That means one step up: TWO chips on each relevant DS, say three DS: 3, 5, 4.
0...Loss. One step down. One chip on two DS: 5 and 4.
13..Loss. There is no step down from here. Say one chip on DS 4 and one chip on DS 3.
3..Loss. One chip on DS 4, one chip on DS 3, and one chip on DS 1.
28..Loss. One chip on DS 3, one chip on DS 1, and one chip on DS 5.
5..Hit! One step up. TWO chips on each relevant DS: Three groups.
                         And so forth and so on.
The session ends after a hit on the 10TH level.
                                                                      Good luck!

Hi Dane!
I do not really get how you pick the DS , ok from start i get it, but not why you play sometimes 2 next 3 and 4  ,
i would be happy if you could explain it so even i understand this!
Thank`s Agesta

Hi Ajesta,
      Translate Danes numbers into DS's Then it should be plain.eg...
1.3.5.4.4.0.3.1.5.1. Track last 4 DS. bet 1.3.5.4. 4 hits last 4ds= 3.5.4.4.
bet 3.5.4.....0 hits. last 4 now 5.4.4.0.
bet 5.4.......3 hits.  last 4 now 4.4.0.3
bet 4.3.......1 hits.  last 4 now 4.0.3.1
bet 4.3.1....5 hits.   last 4 now 0.3.1.5
bet 3.1.5....1 hits.   last 4 now 3.1.5.1  etc
Got it now??  Once you have sorted out the bets the contre D'alembert is easy.

   Go well........ Harry

  Hi Dane,
         I like the bet selection, have you tried it with any other progressions??
      Regards       Harry

Thanks! After a loss on level 3 it might be tempting to go to level 1. But I have not had the time to test it yet.

Hi Dane.

I like your concept very much,but i can't work out how you made 375 chips profit playing DS at 5-1 in only 4 sessions.

Can you explain how you progress to level 10.

Sorry if i have missed something important from your posts !!

Hi Dino,
I was extremely lucky at first.  If you read back the posts, you should be able to understand the method. And you should see, that in my very first session  I was  very very lucky. I started with the first spin of 2011, table 3, Spielbank Wiesbaden. Freely available. The profit accumulated during this session. 
Later I experienced that one session may take several days.
The idea of a positive progression is better than a negative one. Unfortunately this method does not seem to be good enough.
                                                                           

Dane,

Just giving this whole thing a different perspective. I think we will definitely have hot DSs, we will have cold DSs. It is really hard to differentiate. How about an approach which will take advantage of this.
Do you think it will work. I think with the nature of the DS, unless you would like to play them as ECs, we should play a maximum of one DS and only one DS. Anything more or less, will eventually lead to the downfall.

GreatGrampa,
Hot? Cold?
"Yet she´s true like ice, like fire"
Bob Dylan in "Love Minus Zero (No Limit)".

It might be hard work to look at ALL eleven DSs. Most numbers belong to two DS´s. But if we look at all of them, we might be able to differentiate  a little better. And the hottest one right now, the one and only leader, might not be too far away from others.

Dane,

What I meant was something like the one below. Same principles of upping the bet after a win, keeping the bet selection dynamic, but using only one DS.
