Game-forcing auctions after 1M - 1S/NT;2C - 2D
----------------------------------------------
NGF - "Natural Goes First" employed for all responses.
1H - 1S; 2C - 2D is different because opener is limited to 3S and can show 6H-3S.
5-4-3-1s start by showing highest part first because the first opportunity occurs at 2S/2H (other major after 1H/1S respectively); 2NT always diamond fragment, denying 3+ other-major.
Without special distribution (5 hearts, 3-card raise) responder normally continues with cheapest call. With a 5-card support for a potential 3-card suit responder can bid 3-other-major or raise to 4-level (slam suitable).
After a fragment (2OM/2NT) opener's 3H and 3S show particular 5-4-4-0s
After an opening 1S the extra step after 2H allows opener to show 4 hearts (2NT) - except for all 5-4-4-0s above, others show 3H.
- 2-other-major shows 3/4 implies 5-4-2-2 or shortage in minor
- 2NT shows 3/4 diamonds, implies 5-4-2-2 or shortage in other major
- 3C is "wild or boring' - exactly 5M-4C-2-2 or 5-5/6-4 - never 3-suited
- 3D is 5-5
- 3H after 1S is 5-5
- 3M is 6+ cards, not 6-4
- 3NT is always natural (other paths allow responder to show 5H or opener 3S)
- 4m is single-suited, void SPL
After a fragment (2OM/2NT) opener's 3M shows particular 5-4-3-1 or 5-4-4-0
After 3C opener's 3M shows min/max 5-5 because responder doesn't get an chance to support until ambiguity is resolved.
5-4-2-2:
- with 4H; 2H->2NT->3NT
- with 4D; 2NT->3NT
- with 4C; 3C->3NT
Balanced hands:
- after 1H - 1NT;... 3NT
- after 1S - 1NT;... 2H = any bal, with/out 3H
- after 1H - 1S;... with 3S bid 2S, otherwise 3NT
6-4s:
- with 4m; indicate minor (2NT/3C) bid 4m (indicating shortage)/4M max/min
- with 6S-4H; 2H (3+ hearts) -> 2NT [4H] -> 4m [SPL, max]/4S
- with 6H-4S; 2S (3+ spades) -> 4m [SPL, max]/4H
