This scheme includes all the 2-suiter
shapes, all 5440’s and those 4441 shapes with both Majors (ie minor shortage).
On entry into the S2-Scheme, two suits
are always known: viz the long suits for the 2-suiters; the two highest suits of
any 5440 shape and both Majors if 4441. The two suits are always shown by
Suit-Order and direct bids into the S2-Scheme after showing only one suit,
infers Clubs as the second suit.
There is no key bid for the S2-Scheme (2 is
the key bid for the S1-Scheme). This absence of a key bid is what distinguishes
the S2-Scheme from the S1-Scheme.
The S2-Scheme contains three list
of hand shapes:
-
The Main 2-suiter list: M2 = 5431,
6421, 6430, 6520, 7420,…
-
The Equal Suits list: ES2 = 4432,
5521, 5530, 6610
-
The Equal Residue list: ER2 =
5422, 5440, 6511, 7411,…
The 3-suiters with both Majors are
treated separately. First show the Majors, then bid 2. This cannot be confused
with the 2-key for the S1-Scheme, since two suits have already been identified.

Had I not bid the 2 then
Hearts would have shown longer, therefore showing 2-6-4-1. Had I not bid 2NT, then I would have shown a high shortage (Spades). A 1-4-6-2 hand.
Not bidding either 2 and 2NT would have shown
1-6-4-2.
The following features should
be noted:
-
The 5440's with both minors
are placed into the Equal Residue list (ER2-list). With a 5-card Major
and 44-minors you should choose the stronger minor as the second suit.
-
As a memory aid note the
symmetriy of the 3-suiter schemes with both minors:
-
4441 (minors) : S1-Scheme 3-3*-3
-
5440 (minors) :
S2-Scheme 3-3*-3
