VULNERABLE is more traditional
1C= 16+
1D= 10-15 2 or 3 suited
a) 4S & 5+m
m3 (<5S)c) minor 2suiter (m2)
1H= 10-15 4+H (denies m3) also denies 5S unless holding 5+H)
1S= 10-15 5+S (<5H)
1NT=12-15
2C= a) 10-15 6+C singlesuited (ss) OR
weak 2 in D ORc) weak 5+S & 5+H
OTHER as per n/vul scheme
Over every 1 level opening step 1 is relay based on Symmetric principles but opener almost never bids suit held in order to maximise prospect of being dummy.
New non-relay over the multipurpose 1m opening are descriptive but n-f, with higher bids being pre-emptive (noting that if resp hold 44minors there must be at least 8 card fit vul).
Over Major showing bids a) cheapest is relay
simple new suits are transfers c) jump +1 is singleton raise ie splinter with limit or min GF d) other simple jumps are fit-showing +2= 2way either that suit or highest e) one under double raise is limit f) jump raise pre-empt g) jump raise +1= bal min GF raise h) double jumps are switched void-showing splinters (one under)Note 7 card majors are only opened at the one level if weak or 7222 assuming the 7222 does not qualify for the solid with no outside A/K or solid with outside A/K. Intermediate 7 card suits with outside values fit the somewhat liberal definition of "Acol 2". The Acol Two could also be a 65 with six + cards in named Major as it takes those hands out of 1-level openings without upgrading to strong opening.
Many unusual treatments including transfer doubles, specialised cues : the complete system including defences to absolutely everything is about 50 typed pages of theory with some sequences completed (but no examples).
