Divide and Conquer Expanded

[GLC]

This is an attempt to come close to random in our bet selection process.

We play D&C Exp  with 6 positions instead of 3 in the original D&C.  We write these across the top of our paper just like in D&C:
 
1      2       3       a      b      c

We use the next 6 spins to fill in our chart.  Let's say the spins are  10, 24, 18, 3, 29, 34.

The 10 is used to fill in the spots after the 1 and the a.  Since the number 10 is in the 1st dozen and also in the A column our chart looks like this:   1a   2    3   a1   b   c.

24 is in the 2nd dozen and the C column: 1a   2c   3   a1   b2   c

18 is in the 2nd dozen and the C column: 1a   2c   3c   a1   b2   c2

3 is in the 1st dozen and the C column:  1a1   2c   3c   a1c   b2   c2

29 is in the 3rd dozen and the B column: 1a1  2c3   3c   a1c   b2b   c2

34 is in the 3rd dozen and the A coumn:  1a1   2c3   3c3   a1c   b2b   c2a

Now we're ready to start playing.

[We will be betting 2 dozens and 2 columns at the same time.
This divides the board into 9 ea.  4 number sectors. 
We will always be covering 8 sectors.
By covering 2 dozens and 2 columns each bet we will be covering 4 sectors with a dozen bet and a column bet.  A win here nets us +2 units. 
4 sectors will be covered by either a dozen or a column bet.  A win here costs us -1 unit. 
And 1 sector and the zero will not be covered.  A hit in that sector or a zero costs us -4 units.
We always bet the same amount on all 4 locations, i.e. the 2 dozen locations and the 2 column locations.
If we hit a sector with only a dozen or column bet covering it, we lose 1 unit and we increase all 4 bets by 1 unit.   
If we hit a sector with both a dozen and column bet covering it we win +2 units and we decrease all 4 bets by 1 unit.
If we hit the open sector or a zero we lose -4 units and we increase our next bet by 2 units on each of the 4 locations.]

Back to our example.
If our next spin is 6 which is in the 1st dozen and column C, our chart will be:

1a1   2c3   3c3   a1c   b2b   c2a
1                                       c

We put our 1 below the 1a1 and our C below the c2a.

This means we bet against column A of the 1a1 and dozen 2 of the c2a.  If we win on either dozen 2 or column A but not both we will lose 1 unit.  We increase our bets by 1 unit and we bet against the 1 dozen of 1a1 and column A of c2a.

Had we won while betting against A of 1a1 and 2 of c2a, we would have won 2 units and be +2.
  Since we are betting 1 unit we can't go lower so we stay at 1 unit on all 4 bets.

If we win on both 1 of 1a1 and A of c2a while betting 2 units on all 4 bets, we would be up 4-1=+3 and would start over with 1 unit on all 4 bets.

We have 2 chances to win in each location.  If we win on the 1st try, we just record the last spin and fill in the 3rd spot in the dozen and column of our chart.  Then we spin again to see which of the 3 dozens and 3 columns we will be betting against next.

If we spin 23, we will be betting in the location that starts with 2 and also the one that starts with B.
If we spin 25, we will be betting in the location that starts with 3 and also the one that starts with A.  etc...

Our progression never resets unless we reach 0 or +. 
We just continue +1 after a loss of -1;
+2 after a loss of -4
and -1 after a win of +2.

I recommend a 200 unit bank.  JL suggests a 128 unit bank for the original D&C but he uses a different betting method than suggested here.

If you know how to play Divide and Conquer, this should be easy to pick up.

It's somewhat of a grinder, but if you play to +10 units each session, it shouldn't take too long to reach your target.

This obviously takes pen and paper.

Be sure and test it for yourself before risking real money.

The original bet progression is a little aggressive for some people's blood.  I made it that way so it wouldn't take so long to recover after a longer than normal series of losses.

For those of you who don't like big swings in bet sizes, here are a couple of suggestions.

1.  +1 after two -1 losses (that's when you only win on a dozen bet or column bet but not both).  -1 after a win on both dozens and columns.  +2 after a total loss of -4.

2.  No movement in bet size except after a -4 loss increase +1.

Each of these progression adjustments has its own pros and cons.

Choose the one that suits you.

Just for you information I have played 10 sessions to +10 units using the original progression.

My largest bet has been 11 units on all 4 locations for 44 unit loss if zero or one of the double losses hits.

I've never reached -100 units although I've come very close.

So far this is pretty stable.  I know that as long as there is a spin that can hurt us, enough of them can come close enough together to push us to our stop loss.

It's a little complicated to play, but worth the effort so far.

Hello GLC

Its easy 2 play but the original progression can get you 2 quick in d hole in my opinion.  I have not tested it yet though. But maybe betting on 2 separate 1/3 chances could make difference  and be a equalizer?

Thanks for this idea.  What if it came to this:

1a1   2c3   3c3   a1c   b2b   c2a
1xx   xxx    xxx   xxx   xxx    cxx

Where x is any dozen or column.

Would you use the next spin for a trigger?  As in:



1a1   2c3   3c3   a1c   b2b   c2a
1xx   xxx    xxx   xxx   xxx    cxx
         x                x

Thinking as I type, I can see it would be very unlikely to ever happen just that way.  In fact, one might consider betting against it ever happening that way!

RBH,  I agree with you.  I have quit testing the original progression.   I only increase my bet size after a total loss of 4 units.  +1 is somewhat of a grind.  +2 seems to be a good compromise.  So far this is staying very solid.  I've never had to bet more than 6 units on each location and I've won 13 games to +10.

Your buy-in can be 100 units.  I suggest noting what you're betting when you are at -50 units and if you every reach -100 units, drop back to the bet size when at -50 and see if you can recover back to even.  If you drop back to -100 take the -150 unit loss.  If you recover back to even, you can reset to your -50 bet size and try to recoup all losses or you can just take the -50 unit loss. 

We're going to have to take losses periodically.  The above way gives us a shot at easing the pain somewhat.

I'm not sure I understand your question, Sam.  Maybe ask a little different way.

On the other hand, you can tweak this any way you like.   As we all know, one tweak works under certain situations better than the original and visa versa.

All I'm trying to do here is have a bet selection method that isn't a static method that will catch losing streaks periodically.  This seems to keep the long losing streaks at bay most of the time.

I know that this system requires a lot of tracking and writing and in the long run it may not be any better than just betting the last two dozens and columns to hit which would be a lot easier to play.  But as long as it keeps testing well I'll keep posting.

Example:
We start with:     1    2    3    A    B    C

1st spin is 34 -  Doz 1, Col A

1A    2    3    A1    B    C

2nd spin 25 -  Doz 3, Col A

1A    2A    3    A1    B3    C

3rd spin 20 -  Doz 2, Col B

1A    2A    3B    A1    B3 C2

4th spin 23 -  Doz 2, Col B

1A2    2A    3B    A1B    B3    C2

5th spin 22 - Doz 2, Col A

1A2    2A2    3B    A1B   B3A    C2

6th spin 23 - Doz 2, Col B

1A2    2A2    3B2    A1B    B3A    C2B

Now we're ready to play:

7th spin 9 - Doz 1, Col C

1A2    2A2    3B2    A1B    B3A    C2B             
1                                              C

8th spin 4 - Doz 1, Col A
 
Betting 1-1-1-1

1A2    2A2    3B2    A1B    B3A    C2B
1A                                            C1

We win on 1 Col A bet and lose on the other 3 for -1.

Stay at 1-1-1-1 for our next bet

9th spin 17 - Doz 2, Col B

1A2    2A2    3B2    A1B    B3A    C2B
1A2                                          C1B

We lost on all 4 bet locations. 

We were betting against doz 2 and col B but hit both.

Increase to 3-3-3-3 for our next bet.

10th spin 29 - Doz 3,  Col B

1A2    2A2    3B2    A1B    B3A    C2B
1A2                                            C1B
                   3                   B

11th spin 33 - Doz 3, Col C
1A2    2A2    3B2    A1B    B3A    C2B
1A2                                          C1B
                    3C               B3

We won against col B and lost against Doz 3 for -3.

-3 + -1 = -4 running total

Next bet is still 3-3-3-3.

Betting against Doz 2 and Col A

12th spin 27 - Doz 3, Col C

1A2    2A2    3B2    A1B    B3A    C2B
1A2                                           C1B
                   3C3               B3C

We won betting against Doz 2 and Col A for +6 units win.

-4+6 = +2

Reset bet amount to 1-1-1-1 and keep playing until you reach +10.

If you get to -50 you can drop back to -25 and try to recover to zero or plus giving up the 25 units.
Or, you if you drop back to 25 and recover back to zero or plus, you can go back to -25 and try it
again.  If you get back to zero or plus you will have recovered your lost 50 units and can reset to 1-
1-1-1.
