This 8-12 carder in ALL positions as a part of
the singleton/void DELTA scheme: called DELTEX

To unburden your memory this Deltex scheme is the easiest one because it is an extension of the s/v Delta scheme.

The bids of the Singleton Scheme through whole the system,
you can better say openings: for those 8-12 carders the order is: void, singleton, if more voids/singletons the system is:
with 2 singletons or 2 voids, the lowest one = a minimum, the highest one= a maximum in the range.
with 3 singletons the lowest one is minimum, the highest one = a maximum in the range.
10 «21» 0= special treatment.

With 10 «21» 0 MAX you have to take:

if the s/v started with the lowest 0-suit then L= lowest suit left,
if the s/v started with the highest 0-suit then L= highest suit left.
NOTE: if you play the more sophisticated scheme regarding max/min in a 8-12, 13-16 range regarding the fact that you will be able to Pass a minimum bid in the real suit (with the extra bid of 4no trumps meaning the two highest and a 5530, ALL above bids where needed are 1 step higher.


Any way for all the shapes with a 1-suiter and an 8- upto 12-carder you know under the 4 level the exact distribution and a minimum or maximum in the range up to 15points from Pass opener and up to 10/11 points from RR (else with more points all one level higher, as usual).

Up to you to use this (uniform) scheme or the two other ones of which one you have more information about AK + side values etc., but no information about s/v and exact distribution.

After a 4 Bid next bid (if not L) is starting the spiral scan, that means asking for the number of controls, Then next bid starts with scanning L first, then next bid asking for the Queen+scan. But after giving the number of controls and 2nd. step is start scanning without L/or Queen L because you are not interested in L or you can deduce later with knowing the placing of A/K in the other suit(s)

Because in the stage after a 4 bid Ace/King and placement cq. A or K in 8+ suiter? is the most important issue. Therefore Spiral Scan method to be preferred. But CAB bid not 4 or higher, then use the normal Slab method.

If you prefer not to open these 9c 1-suiters as a part of the Delta openings, then it is a 4 opening:
10chearts opening minimum OR 10chearts opening max (No AKhearts opening) OR AK 9chearts opening and no side value, and you will end in 4.

 

Example of final distribution is known above normal level: then no CP/Spiral Scan and if Max--> Zoom!

*4hearts opening = Distribution relay. You are not interest in 32 or 23 diviation of the side suits. But a final 4 bid is the maximum for a CP/Scan level, reason why now the 'standard' Slab method

** 5 is the last possible step. Because of the lack of bidding space you must help partner. 9 Points known, 3 Jack's possible only. So Partner- if he needs that info- can bid after 5: 6 = Jack? and then 6 just in time to say NO, sorry Idont have it with f.e.
