System Notes: Sher-Neill Canape Precision 1C opening: 16+ (may be very good 15). Over this TOSR when midchart is allowed, and stock precision otherwise. 1D May be as short as 1. Balanced, both minors, Diamonds or any 4x1. 10-bad 15 HCP. 1D-1M-1NT = 13-15 NV, 11-12 Vul 1D-1M-3M = ?? I guess not used. 1D-1M-2OM=Max 4441 hand with 4card support and any stiff. 2NT relays for stiff: LMH. 1D-1M-3C= 5-5, 13-15 HCP 1D-1M-2NT= 6+ D, 3 card support, max hand 1D-1M-3D = 6+ D, max hand <3 M 1D-1M-2C= exactly 9 cards in the minors. 1M 4+, if only 4 has a minor canape , if 5 cards then 5332 only if outside of NT range (unless the suit is so strong you want to claim it is a six card suit), otherwise 6+ cards. May be AKJxxx or AKQxxx and out. Normally 10-bad 15 HCP. Over 1M: 1S natural and forcing for one round, but limited to 13. 1NT Forcing for one round, may contain a GF hand (new suit or any JS). Tends to be balanced or semi-balanced if less than GF. 2lower suit Natural, constructive (usually 8-12, but may be light in search of a resting place....) 1M-2M Natural and constructive (typically 8-10). Usually 4 card support but may be Hxx with side shortage (weak doubleton or worse) 1M-2NT = Natural 13-15 or 18+. 2 or 3 card support. 1M-3NT = Natural 16-17 with bad trump support (does not have 3 card support AND a side doubleton) 2S/1H or 3C/1S = GF 4card raise: Step Responses: 4cM min, 4cM extras, 5+cM min, 5+cM extras. The next relay asks shortage (NonHighMiddleLow=NHML). Super relay over the 4 card responses asks for the canape minor (HL). 3C/1H or 3D/1S =Inv 4 card raise. In between bid is an artificial counter try. 3D/1H or 3H/1S = My suggestion is 16-17 balanced with 3 card support for M. Responder can bid 3S to x-fer to 3NT, bid 4M to play, a minor as natural and canape and bid 3NT as a slam try in the Major (3H when available shows 5332?). 3M pre-emptive 0-8 HCP May be only 4 cards with some shape but often is 5 cards. 1M-1NT-2X-2NT natural and Inv. (X not equal to M). 1M-1NT-2X-3X " 1M-1NT-2X-3X+1=GF raise. Sets trumps. (N.B. 1S-1NT-2H-3S is a heart raise!) 1M-1NT-2X-New Suit = Natural and GF 1M-1NT-2X-2M = 3 card support, unbalanced hand with limit raise values that can not bid 2NT or 3X. 1M-1NT-2M-2NT=Mod. Ogust 3C 6 card suit 8-9 or strong 6+ card suit 10-13 (Would have jumped to 3M with 14-15) 3D asks 3H= 8-9 3S=10-11 3NT=12-13 3D 5332 13-15 3H Bad Suit 10-12 3S Bad Suit 13-15 3NT AKQxxxx or AKQJxx and out 1M-1NT-3M = Very Strong 6+ card suit, max hand 1M-1NT-3m= Canape 4-6 hand, max, great 6 card suit 1M-1NT-2NT=In theory this should be a max 4-6 with a solid suit, but this messes up the 1NT and bid a new suit structure. So what should this be???? Maybe 4441 or 4054 max's with both minors? 1NT opening (10-12 seats 1-3 NV, 13-15 in 4'th seat or VUL. 5 card major allowed for 10-12 NT. Almost never offshape: 2C: forces 2D Shows either a hand that wants to play 2D Game forcing hand (suit rebid) Quantitative invite (2NT rebid) Any suggestions for a 3NT rebid????(Maybe 4-4 in minors and mild slam try??) 1N-2C-2D-3M: 5 card suit, choice of games 1N-2C-2D-4M: very mild slam try Therefore going slow and bidding and rebidding your suit is a serious slam try After, 1N-2C-2D, bidding is natural Note: if responder bids both majors he is making a slam try since the choice of major suit games auctions start with 2D not 2C. After:1NT-2C-2D-2S-2NT-3H-? 3S sets spades as trumps, 4 of either minor is a cue bid setting hearts as trumps (with 4 card heart support) 2D: asks for better major (with 3-3 always bid hearts) Shows: 4-4 or better in majors weak Suit oriented invite (usually with a 4+ card major, maybe with a 6 card minor) Smolen(jump to 3NT is opener bids your 4cM, Jump to 4M if opener bids your 5cM) Choice of major suit game(raise preference to game) Over:1NT-2D-2H: 2S shows 4/5 spades invite 2NT: shows 4H invite 3m: shows 6 card suit invite 3H: shows 5+ hearts invite 3S: shows 6+ spades invite 3NT: 5 Spades, 4 Hearts, game values 4H: to play Over 1NT-2D-2S: 2NT shows 4/5 hearts invite 3m: 6 card suit invite 3H:6+ hearts invite 3S: 4+ spades invite (Note: this is awkward since it may be a 4-3 fit) Opener should accept with 3NT holding only 3 spades and a max. 3NT:4 Spades, 5 Hearts, game values 4S: to play Other Suits at 2/3 level are to play: 2NT: both minors weak or strong, if strong bid shortage next (WE can remove the strong meaning if desired). Over 1NT-x(strong hand): Don't style runouts. (Suit is that and higher suit. xx forces 2C to show a 1 suiter) Over 1NT-2C(artificial): Systems on Over all other 2 level interference, negative doubles and rubensohl. Rubensohl agreements: 2NT is sign off in any suit, stayman with a stopper, or GF with clubs 3C Inv+ with D 3D Inv+ with H 3H Inv+ with S 3S Values for 3NT but no stopper 3NT to play x-fer into the opps suit is stayman without a stopper. 2C opening 6+ clubs no 4 card major 10-bad 15 HCP 2D relay 2M fragment 2NT max, at least two suits with stopper 3C min 3D max 4+ Diamonds 3M max, shortage 7+ clubs 3NT max 7222 2M constructive not forcing 2NT Sign off in 3C or strong hand with own suit 3C Mild Invite 3 Higher Splinters 3NT to play 2D opening.
