Double transfer responses
[edit]1C*-? positive two-steps when opener relays (inclg both 1H-1S/1N)
- supposing that -1N = all hands >=44 Majors; -2D = 5+ hearts only
- here '+' represents 1.5 or one specific 444
- 5440 not covered here (12 rareties, sum 2%) but see double-indent remarks
-1H...1N/2N idle below 3S --as 3C/3D/3H splinters
- 57+
- 12. 1H 2C
- 12. 1H 2D
- 14. 1H 2Hj --namely 2H and 3C/3D/3H
- 19+ 1H 2S : 4=344 -2 (1 flat, two 4432, one 4441[void?])
- unless 2S=4144[void?] and 2N otherwise
-1S...3N idle below 4C --as 3D/3H/3S splinters
- 74+, about 38% of all hands
- 50+ 1S 2C : clubs[14] or 3444 -2[36+] (3 flat, three 4432, one 4441[void?])
- except jump splinters --namely 3D/3H/3S
- 12. 1S 2D
- 12. 1S 2H+ --namely 2H/2S/2N/3C
-1N...available perhaps 2S/2N/3C/3D
- 19++
- 12. 1N 2D/2H
- 7++ 1N 2S : 4=4(32/41) (one 4432, two 4441[void?])
- 2N=4405?
- 3C=4450?
-2C...3N idle below 4D --as 3H/3S/4C splinters
- 26
- 14. 2C 2Hj --namely 2H and 3H/3S/4C
- 12. 2C 2S+ --namely 2S/2N/3C/3D
-2D...available; splinters may be defined as cheaply as 2S/3m
- 14
- 14. 2D if/because one-suit always
= 196 covered by this accounting, or 190++++
2015-02-12, four 5440 not covered here, nor 74; about 2 and 2 of 200 hands, or 1% each
The crux may be adequate handling of
-1S-1N-2C (where 3N alone is idle below 4C --as 3D/3H/3S splinters)
- 50+, about 26% of all hands
- : clubs[14] or 3444 -2[36+] (3 flat, three 4432, one 4441[void?])
- except jump splinters --namely 3D/3H/3S
