Main feature:

- 1S - 2C = H suit, could be weak 5+ or FG 4+ (never GT)
- 1S - 2D = C suit, FG, 3-H else 6C-5H
- 1S - 2H = D suit, FG, 3-H else 6D-5H, 4-C (both minor -> 2D even if 6D5C)
- Jump features a (good) fit, and some side suit fragments (avoiding to bid a weakness)

Notations:

- R = m+1
- ssol(semi-solid) = 6+ cards, 1- flaw on the suit

## CM reversal 2/1

1S - 2C = (1) 0-2S, 5+H, 6-10 (2) 4+H, FG, but not 6m-5H big thing
1S - 2C; 2D = F1, 0-1H if 5S, or something positive.
1S - 2C; 2H = NF, 2-3H if 5S, 3H if 6+S.
1S - 2C; 2S = NF, 0-2H, 6+S.

1S - 2C; 2N = Any 18p+

Over 2m+2 waiting bid, responder's rebid:

:::info
1S - 2D; 2H - 2S = ~~5C-5D or better, equal length on minors~~5+C, 5+D, minors hand, almost no interest on major unless 7+S.

1S - 2m+1; 2m+2 - 2N = 2-S, seeking for minor fit as in 2/1
1S - 2m+1; 2m+2 - 3N = To play, 0-2 S.

1S - 2m+1; 2m+2 - 3C = 3-card S fit without void or 6m
1S - 2m+1; 2m+2 - 3D = 6m catch-all, could have 3S fit.
1S - 2m+1; 2m+2 - 3H = 6m-5H
1S - 2m+1; 2m+2 - 3S = 6m-5om
