We make a diviation for balanced shapes and shapes with a singleton or void (shortness).

BALANCED     :   from 4333 up to 7222, so in any case at least a doubleton in each suit

SINGL. / VOID :   -DELTA from 4441 up to 7330
                          -EXTREME from 74, 65, 8 up to 13
(1 suiters option: -DELTEX scheme within the Delta openings)

Because of the symmetric building of the system, the Balanced, Singleton Delta and Singleton Extreme schemes are used through whole the bidding sequences consequently. So you have to practise 3 schemes for the diviations only.
When I refer in a sequence - although it can be sometimes on a higher or other level - regardingless the pointrange
to f.e.

diviation scheme	opening	suit information	description
Balanced	1	Longest =	5332, 5422 or 6322 distribution (5332 good suit)
Singleton Delta	1	Shortness in	Delta shapes
Singleton Extreme	2	Anchor =	7-9card + a 4 card other with a minimum 4card + 7-9 card other with a maximum 6/5, 6/6, 7/5 in / min/max

the opening keeps always it's same and unique meaning. As illustration already:
[in Brown = the R(elayer), in Blue = RR (responder to relayer) lateron the R can become RR , then in black]

BALANCED 1	relay + info	relay + info	description
1 = 8-12 Longest = 5332, 5422, 6322
[Pass] = 13+ any	[1] = main 6-11 bal. or 12+ any	[1] = bal or ++ any	1= 6-11 Longest = 5332, 5422, 6322

DELTA 1	relay + info	description
1 = 8-12 with Shortness	[1] =13-15 without a Major/16+	1 = Shortness in
[Pass] = 13+ any	1 = Shortness in 6-11
[Pass] = 13+ any	[1] = main 6-11 bal. or 12+ any	1 = Shortness in 13-16 points

EXTREME 2	relay + info	description
2 = 7-11 Anchor =
[Pass] = 13+ any	2 = 5-10, Anchor =
[Pass] = 13+ any	[1] = main 6-11 bal. or 12+ any	2 12-15 points, Anchor =
[Pass] = 13+ any	[1] = main 6-11 bal. or 12+ any	1 =13+ balanced or ++ else		2 11-14 points, Anchor =

After [Pass] = 13+ and a 0-5, the pass opener R can ask for extreme shape too in case he is strong
After [Pass] = 13+ and a 12+, both partners can describe their strong Extreme opening by the standard bid of f.e. 2, each time within a 4 points range, but balanced hand will be the R.Same applies for the Delta Singleton Openings.

Before it leads too far at this stage I would like to continue with the subject of this chapter:

the 3 shape schemes:

BALANCED through Double Transfers in case opening bids can be bid *
opening	suit	description
1	?	4333 4432
		5332 and poor
		5332 and poor
		5332 and poor 5422
		5332 and poor 5422
1		5332 and good 5422 6322
1		5332 and good 5422 6322
2		5332 and good 6322
2		5332 and good 6322
2	?	any 7222

* in 1st/2nd seat Openings
* in sequence: [Pass] - [1] - [1] - and then 1/2 openings = 6-11 points
* in sequence: [Pass] - [1] - [1] - and then 1/3 = 6-11 points and the 1 opening (as if there were given a 1 relay)

In other cases the diviation for balanced distribution types is:
- 4333,4432
- each suit 5332,5422, 6322 (so no specification for 5332 poor/good suit)
- 7222 with indication poor/good suit OR closed with information about the side value
It depends on the total sequence if a suit itself is mentioned or through a two/three-way bid. But all will be done consequently.
(f.e. 13+ opposite 12+ balanced a 2 bid = Majors or 4333/4432, 2 bid = minors, 7222 in both bids, see basic sequences and balanced general set-up.).

Re: poor/good:
good = 2 of 3 tophonours (or if you like 3 of 5). I prefer 2/3 because of better slem investigation.

The bids of the Singleton Scheme through whole the system,
you can better say openings:

OPENING	Singleton / Void in	Description
1	S	All groups
	S	L=, L= , or any 5/5
1	S	All groups
1	S	L=, L= , or any 5/5
2	S	L=, or 3-suiter
2	S	L=
2	S	3 suiter

incase of + or ++ strength, all bids one level higher

Singleton/void EXTREME scheme
Bid		Description
2	7/8/9 in and 4 card in // with a minimum 4 crd.in and 7 /8 /9 in // with a maximum 6/5 or 7/5 in and vv
2	7/8/9 in and 4 card in // with a minimum 4 crd.in and 7 /8 /9 in // with a maximum 6/5 or 7/5 in and vv
3	7/8/9 in and 4 card in // with a minimum 4 crd.in and 7 /8 /9 in // with a maximum 6/5 or 7/5 in and vv
3	7/8/9 in and 4 card in with a minimum 7/8/9 in/ and 4 card in with a maximum 6/5 or 7/5 in and vv
3	7/8/9 in and 4 card in with a maximum 6/5 or 7/5 in and vv
3	7/8/9 in and 4 card in with a minimum 7/8/9 in and 4 card in with a minimum 6/5 or 7/5 in and vv (but I prefer the 3 bid for this shape)
rest of the Extreme (8+ single suit) 1st/2nd position and a 8- (can be solid) or 9-carder (not solid!) and both single suited : open 1
If you prefer uniformity for the 1-suiter 8-12 carders see Deltex scheme combined within the Delta openings namely

incase of + or ++ strength, all bids as above
