we are playing a strong clubs starting a 15 where there is no D hands under 22 nor M hands in the 18-22 range.

my main features is using 1C--1D waiting and getting rid of all 6-bad8 inv so that 1C--1D--1H show a balanced hand 15-20 and 1C-1d-1h-1s-1nt is is still wide 15-20

---------------------------------
This free up

1C--1D--1Nt (forcing, clubs or 21+ bal) wich is a killer improvement.
1C--1D--1H bal--any responder responses is forcing add huge amount of space.
------------------------------------------


-------------------------inv recap.
inv with 4H are in
1C--1S
inv with 4S are
1C--1H
inv with a long m are in

1C--1D--1H (bal)--??
1Nt (5c inv or +)
2C (5D inv or +)
inv with short m are 1C-1NT, 1C-2C (44)(41) + (43)(15)
inv with 3334/3343 are lying by showing 4S inv then pulling to 2Nt or stop in 2D.
inv with 3244 are showing 4M (if raised 2M will play well)



1C---???

1D =(waiting, many weak hands, many GF hands, inv with 5 in a suit)
1H = 4s weak/inv, 3244,3334,3343 inv. any 6S hands, some 5S GF
1s = exactly 4h inv, 6h gf
1nt = short C inv(3 suiters)
2C = short D inv

i know it look weird but keep reading.


1C--1D--???

1H bal 15-20 or GF red suiters-- this is core sequence of system
1S 5S 15-17 or GF
1NT clubs or bal 21+ or GF (4441)
2C 5H+4C+S tol 15-17
2D 5H +4D+ S tol 15-17
2H 5H+4s(15-17)
rest is 5H/4S GF

1C--1D--1H--???

1S weak or GF relay
1NT = 5C inv or better
2C = 5D inv or better
2d = 5H+D GF
2H = 5H + S GF
rest is 5H + C GF
-----------------------------
1c--1D--1H--1S

1NT = bal 15-20 (with stransfers GF or weak after that/stayman Gf)
2c=5H+4D 15-17 without S tol or gf.
2D=6H GF or 15-17
2H+=rest is D GF
------------------------------------

1C--1D--1H---1NT---??
2C bal min
2D 6H weak or GF
2H bal 18-20 GF
2S rest is D GF
----------------------------
1C-1D-1H-2C-???
2d bal min
2H 6H 15-17
2S rest is GF
-----------------------------

1C--1D--1S-- our usual system
-----------------------------------
1C-1D-1Nt Same system after 1C--1??--2C showign clubs (but opener can have big bal)

1c 1d 1Nt 2C
pass 16-20 clubs
2D bal 21+ range check
2H nearly GF nat 5C + 4H
2S nearly GF 5C + 4S
2NT GF 6 clubs
3C 21-22 clubs NF

--------------------------------------------------------

1C--1H(spades/ could be 3 cards if inv)--???
1S extras,any 4S fit,any clubs hands
1NT min no fit.
2C 4C+5H 15-17
2D 4D +5H 15-17
2H 6H 15-17
2S 5S 15-17

------------------------------
1C--1H--1S (extras)
1NT (0-5 but show 4S)
2C inv
2D inv that is now GF (3/4)
2H 6S (weak or GF)
rest is GF 5S + os
--------------------------------------------------
1C--1H--1S--1Nt (0-5 but showing 4S)
pass extras but not 4S
2C clubs 16-20
2D range check
2H S raise, GF or to play 2S
2S H GF
bal GF
3m nat GF

-----------------------------------------------------------------------
1C-1H-1S--2C (inv)
pass = clubs 16-17
2D = min with 4S/ but also 4D or 4234,4432 (to allow 2D to be better than 2S if responder is 3343 inv)
2H = S raise min or GF
2S = GF with H
rest is GF nat
------------------------------------------------------------

rest is later
