The system is based on a symmetric scheme consequently through all the sequences.
Next step in a basic sequence is normally the variant with stronger shape sorts (as mentioned in the diviation scheme there are three sorts of shapes only).

Higher steps are a description of the shape sort itself in the given pointrange with a margin of 4 points. In the pointrange itself we use a minimum and maximum, each with a margin of 1 point.
In case the margin of a pointrange is 5, the two highest points are a maximum. See pointrange diviation scheme.

All as a guide because f.e. Jack/Queen singleton does not count, you have a good or poor card. But basicly you are committed to restrict yourself to the point ranges. I will explain why. In case R asks for your complete distribution in a certain type, does a slemtry, asking for your AKQ values in other suit(s), knowing his own values and yours, he can count that f.e. the only points left within your pointrange if he has AKJx in both majors must be a Queen in your major tripletons.
Same applies for so called "soft" values (to much QJ in the suits ànd no A/K or AQ, KJ or KQJx besides that), which I count as a minimum too.

In case shape sort and pointrange is known the next step is the only forcing bid for the R. In further bidding cheapest bids are relays too usually.Normally from the start of a sequence the third relay is forcing at least to game. In balanced shapes after 2 forcing relays, 1st step is exact distribution asking, 2nd step is asking for stops, 3rd step is asking to bid controls (you can ask for AKQ values after complete distribution is known too, but there are situations that looking for an important control will be better, see working outs in the shapes chapters (as a preview see appetizer page)
In case 13+ against 6-11 balanced same but depending on the suit, sometimes there is an adjustment in the scheme in a logical way.
In case 13+ against 12+ cheapest and other steps are of course forcing.

After a Pass (13+) both partners start the sequence with telling their pointranges and in case of reaching a certain pointrange if he has a singleton/void shape (at the same time in which suit singleton/void or which Extreme one) or a balanced one. Balanced ones with the lowest bids possible so that the balanced hand still maintains R in case partner has the lowest possible pointrange-level for a singleton/void shape. If not , the unlimited hand remains the R. Resulting that the weaker hand tells in an earlier stage his kind of shape in a sequence and there is a balance between the two point-ranges regarding the fact when to tell your partner I have a S/void shape which has a higher pointrange-level than yours. So the shape and maximum pointrange of the more stronger hand (=R) is unknown to the opponent.

Underneath the main Basic sequences after Pass (13+) -

in Brown =R (Relayer)
in Blue = RR (Responder to Relayer)

lateron the R can become RR , then coded in black
and automatically RR becomes R ,and coded in green

and finally:
R can become again/return to RR , then in bright blue
and automatically RR becomes again/returns to R , and coded in grey

There is an inconsistency in the sequence underneath regarding the setup of the total scheme.Namely lowest bid is the strongest variation ànd no indication for the 7222 if poor/good suit (although any 7222 closed with indication of sides Ace(s) maintained).
But against the bid of 2clubs (18+ Bal, 21+ Delta,) the balanced minors 14-17 need a bid.

go to complete working out of above scheme

 

 

In case there was not a cheapest bid (= the strongest one) in the basic sequence, partner can still partly describe his limited in pointrange singleton/void Delta/Extreme shape opposite the given limited balanced one but don't do it, even with a maximum, with a Ace-less hand because:
- you are already 1 complete level higher in the Delta scheme as usual
- therefore RR must be able to break the relay sequence for control-asking etc. ,ask for more controls or exact distribution
- or without breaking the relay to ask for full distribution.
- in case of an 0-3 answer on Ace asking, specially if that bid is the trumpf suit, he will be in big trouble

- see example

[as reminder:
in Brown =R (Relayer)
