Häxan ===== Game-forcing auctions after 1M - 1S/NT;2C - 2D ---------------------------------------------- 1H - 1S; 2C - 2D is different because opener is limited to 3S and shows 3-card support immediately. 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 5-4-4-0: - 0=5=4=4: 2NT->3S - 4=5=0=4: 2S-> 3H - 4=5=4=0: 2S-> 3S - 5=0=4=4: 2NT->3S - 5=4=0=4: 2H-> 3H - 5=4=4=0: 2H-> 3S Hearts 5-4-3-1: - 4=5=3=1: 2S->3D->3S ~ "3/4S..3/4D..4S" - 4=5=1=3: 2S->3C->3S ~ "3/4S..3/4C..4S" - 3=5=4=1: 2S->3D->3N/4C ~ "3/4S..3/4D..4D min/max" - 3=5=1=4: 2S->3C->3H ~ "3/4S..3/4C..4C" - 1=5=4=3: 2NT->3D ~ "3/4D..4D" - 1=5=3=4: 2NT->3H ~ "3/4D..4C" Spades 5-4-3-1: - 5=4=3=1: 2H->2NT->3D ~ "3/4H..4H..3D" - 5=4=1=3: 2H->2NT->3H ~ "3/4H..4H..3C" - 5=3=4=1: 2H->3D ~ "3/4H..4D" - 5=3=1=4: 2H->3H ~ "3/4H..4C" - 5=1=4=3: 2NT->3D ~ "3/4D..4D" - 5=1=3=4: 2NT->3H ~ "3/4D..4C" ====================================================================== ====================================================================== 1H - 1NT -------- 1H - 1NT 2C 16+ or 6+ hearts 11+ - "long or strong" 2D 11-15, 4+D 2H 11-15, 4+C (if 5C, 11-13) 2S 13-15, 6H+4S 2NT 13-15, 6H/4-minor 3m 13-15, 5-5 3H 13-15, 6+M 1H - 1NT 2C - 2D 8+, FG opposite strong-type 2H <8, to play opposite 6H and 16-17 2S 11-12, minors, short heart (## TODO ##) 2NT <8, 5-5 minors, short hearts 3m <8, 6+ minor, short hearts 3H <8, Natural, possible game Responder is weak ----------------- 1H - 1NT 2C - 2M 2S 18+ 5+H-4+S 2NT 18/19 Bal, good cards (3m Nat NF) 3L 18+ Nat, FG 3H 17/18 NF 3S 5=6 suitable values 3NT Solid major, choice of games 1H - 1NT ~ Responder is strong (8+) ----------------------------------- 1H - 1NT 2C - 2D 2H 11-13, NF all other FG, 6+H, (2S/2NT/3L tries with 2+H [maybe sing. honour?]) Others 16+ 2S 3/4S - 4 spades and/or shortage in minor 2NT 3/4 diamonds NOT 3+S 3C Clubs, "wild or boring' 5-5/6-4 or 5H-4C-2-2 3D NAT Diamonds, 5-5 (3=5=5=0 possible) 3H Nat 6+H 3S Nat 5=6 (maybe light) 3NT BAL 17-19 4m Void SPL Opener shows 3+ spades ---------------------- 1H - 1NT 2C - 2D 2S - 2NT Normal without 5+ suit 3C Nat, 5+ clubs 3D Nat, 5+ diamonds 3H Nat, 3CR, COG 3S 5-5 minors 3NT Enough 1H - 1NT 2C - 2D 2S - 2NT 3C 3/4C short diamond {3=5=1=4 / 4=5=1=3} (3S implies diamonds; 3D?
