Bids that Require Advance Preparation

ACBL Pre-alerts:
1M could be canapé
Our 1m openings are artificial, 1D forcing and 1C forcing 3rd/4th seats

Other opening bids, responses and competitive calls that may require advance preparation, but are not ACBL pre-alerts are listed at the bottom of the general bidding style. In general, people like to make defenses against 1C art., 1D strong, 2NT strong and limited with 6+S and rarely against 1NT for t/o and 1C-1R transfers.

General Bidding Style

Strong D, Weak 1M/2m
[For points listed here, we routinely upgrade HCP ranges according to ACBL's Rule of 17/19 (e.g., 5-5 Majors 9HCP will routinely be upgraded to a 10-14 artificial 1C). We routinely downgrade control-poor hands. These are on top of any other permissible controls, quality or concentration related upgrades or downgrades which are usually 1 point and rarely 2+. Some upgrades are not permissible such as 9 to 10 for an artificial bid for anything other than rule of 19.

List of Openings:
1C = 0+C; art.
-1st/2nd 10 to 14 nf;
-3rd/4th 14+ to 17 unbal forcing usually no major unless 4M-7m
1D = str 0+D; art; forcing; we will open this instead of 2NT if we want to ask/bal/bad suit;
-1st/2nd 15 to 37;
-3rd/4th 18 to 37
1H = 4+H could be canapé, we open every hand qualifying for 1M this or something else;
-1st/2nd 8 to 11;
-3rd/4th 14+ to 17
1S = 4+S, 0-3H could have longer m;
-1st/2nd 8 to 11;
-3rd/4th 14+ to 17 4+S, H shorter than S typically
1NT = Either natural or could have one small singleton, no void and 9 or fewer cards in two longest suits;
-1st/2nd 12 to 14;
-3rd/4th 15 to 17, no 4+Major
2C = natural
-1st/2nd 0-5D, 0-4S, 0-4H; NV 4+ to 9, 5-6C; V 6+C; VV 7+ to 11; RvW 10 to 14;
-3rd 5+ 0-14
-4th 5+ 13-14
2D = natural
-1st/2nd 0-5C, 0-4H, 0-3S; NV 4+ to 9, 5D; V 6D; VV 7+ to 11; RvW 10 to 14;
-3rd 5+D 0-14
-4th 5+D 13-14
2H = 5+H;
-1st/2nd: 11 to 14, 5H4m(31) or 6+H, 0-3S;
-3rd: 0 to 14 any distribution;
-4th: 13 to 14 any distribution
2S = 5+S;
-1st/2nd: 11 to 14, 5S4m(31) or 6+S, 0-3H;
-3rd: 0 to 14 any distribution;
-4th: 13 to 14 any distribution
2NT = 6-7S 0-3H usually single suited
-1st/2nd: 15 to 17
-3rd/4th: 18 to 19
3NT = solid minor
-1st/2nd: no side A or K
-3rd/4th: Gambling/Preemptive, expectation game can make vs. a random 5 count but slam is unlikely
4m = NAMYATS 8.5 tricks+

Psychics/awkward situations where we violate system: We tend not to be crazy third seat because we are systemically crazy first and second. Have rarely opted to show Kx when holding stiff K in relay or add a card to AQ and subtract a card from xxxx; rare because it will be two cards off actual pattern. When we cannot show 8+suits, 7411 or 12+ cards in two suits in relay so have to represent another pattern if responding to relay.
Forcing pass: We play pass double inversion when one of us has made a game forcing bid. This does not apply to a game raise. In some invitational sequences (e.g., 1D-1H and 1C-2C) our direct passes of bids are forcing below 2NT.

Relay notes: For all openings 1st/2nd through 2NT and 1m/2NT 3rd/4th there's a response that forces game and initiates a subsequent relay. To prevent relay:
1C-(1S) is high enough
(1X)-X-(1NT) is high enough 2nd, we do not play relay after 3rd and 4th seat power doubles
1D-(1NT) is high enough
1M-(1NT) is high enough 1st/2nd if it is natural or shows 2 known suits otherwise 2C, no relay 3rd/4th
1N-X is high enough if it cards/penalty/takeout or shows two known suits, (2C) is high enough 1st/2nd if it shows two known suits, otherwise (2D), system off 3rd/4th
2C-(2D) is high enough 1st/2nd, no relay after initial response 3rd/4th
2D-(2H) is high enough 1st/2nd, no relay 3rd/4th
2H-(2S) is high enough 1st/2nd, no relay 3rd/4th
2S-(2NT) is high enough 1st/2nd, no relay 3rd/4th
2NT-(3C) is high enough if it shows two known suits otherwise (3D)
3C-(3D) is high enough

To interrupt relay once started,
Typically 3 steps
Before pattern is shown, if there is one-step interference (e.g., 1D-1N; (2C), opener has a penalty double available. After a double, asker and responder have a penalty redouble available before pattern has been shown, afterwards only asker has a penalty redouble.

General style: We play a strong diamond system with many weird openings, competing calls and follow ups.
In the 15 to 37 range in 1st and 2nd seats we have 2 calls:

2NT = artificial, 6+S 0-3H, usually one suited, 15 to 17

1D = artificial, 15 to 37

In 1st and 2nd seats in the 10 to 14 range we have six calls available:

2M = natural;
-5M4m(31) or a 6M0-3oM;
-11 to 14

1NT = 12 to 14 HCP, natural or natural NT pattern but with a small singleton, but still NT oriented: (4441), 6m331 or most reverser 5431s

1C = 10 to 14, art., 0+C, nf

1M = 8-11 4+M could have a longer side suit, 1S also shows 0-3H

-We prefer to open 2M or 1NT to 1C or 1M (but may open 1C with a 2M shape if we do not know whether to accept an invitation or not).
In the 8 to 9 range we can either open 2m not unfav, at the 3-level or above or, if we have a 4+card major, we open 1 of a major.
We will prefer 1M to 1C 8-10 or 11 bal/4441, but will downgrade 12 sometimes e.g., 0-1 control.
10 to 11 hands with 4+M we tend to avoid 1M and instead bid 2M or 1C if they are 11 5431, or 10 with more shape unless they have 0-1 control.
Our style is to open all 10 HCP hands even 4333 and all 8+HCP strength hands with a 4+M. We can upgrade or downgrade (with some exceptions imposed by the Open+ chart like not being able to upgrade from less than near average to near average to open 1M or from near average to average to open 1C). Our opening preempt style is disciplined on tricks and length, but not suit quality. Length is 6+ 3-level (exc 7+ 3C 1st/2nd and 3DV 1st/2nd), 7+ 4-level and higher.
In 3rd and 4th seats, since we already opened all 10+ and most 8+ hands, we increase the strength requirements for our strong bids to 18+. We add another forcing opening: 1C with 14+ to 17 usually no major suit unbalanced. Our 1M are 14+ to 17 and 1NT is 15 to 17.
In the 15 or higher range, we have 6 bids
1C = 14+-17 unbal, usually no 4+M unless 4M7m
1D = 18+
1M = 4+M
1NT = 15-17 denying 4+M; either natural or (31)(54)/(33)(61) with a small singleton.
2NT = 6S0-3H, usually one suited 18-19

In the less than 15 range we play 2X natural and 3C+
2X = 5+X
-3rd 0 to 14 and no distribution requirements
-4th seat, it is 13 to 14.

In 3rd seat, we will pass 0-14- hands with no 5 card suit, in 4th also pass with 0-12 and a 5 card suit.

Other opening bids that may require advance preparation:
1C 1st/2nd seats = 10 to 14,
-artificial like a strong club even though it is not strong
-could be as short as 0,
-non forcing.

1D = 15 to 37
-Some negative inference that opener did not opt to open 2NT;
-3rd/4th seats 18 to 37

2NT = 15+ 6-7S 0-3H usually no side 4+suit
-1st/2nd seats = 15-17
-3rd/4th =18-19

Responses that may require advance preparation:
1C-1R 1st/2nd seats = transfer, 0-11
1C-1S 1st/2nd seats = GF art.
1C-2C 1st/2nd seats = 12-13 HCP,
-does not promise 4+M

1D-1H artificial;
-semi positive;
-1st/2nd seats 6 to 9 or a quick trick;
-3rd/4th seats 4+-7-, 4+ will have at least one control.

1D-1S artificial,
-double negative,
-<1 quick tricks,
-1st/2nd seats 0 to 5,
-3rd/4th 0 to 4, if 4, no controls

1D-1NT+ = artificial, game forcing

1M-2C 1st/2nd seats = artificial, game forcing
1M-2D = Art, inv+ (4+ card support 3rd/4th)
1M-2oM = NF not a drop
1N-2C 1st/2nd seats = artificial, game forcing
2C-2D = artificial game forcing
2D-2H = artificial game forcing
2H-2S = artificial game forcing
2S-2NT = artificial game forcing
2M-3lower = forcing, artificial inv+
2NT-3C = artificial, game forcing
2NT-3R = Jacoby (may req. def. b/c 2N=6+ STR)
2NT-4m = SPL
3C-3D = artificial GF

Competitive calls that may require advance preparation:
(1 of a suit natural) – 1NT = takeout, 3+ @ unbid
-typically 8 to 17- 2nd seat
-10 to 18- 3rd/4th seats)

(1 of a suit natural) - Double = str NT overcall typically, 2+ in suit doubled,
-2nd seat: 15 to 37,
-3rd/4th: 18 to 37,
-(1S)-X also shows a stopper;

vs. 1 level openers
Overcall structure style vs. not Precision 1C (see convention card for Precision 1C defense); two suiters 10+cards usually unfavorable and always if force 3-level
--8-16 if partner UPH, 10-18 if partner PH
--lowest Roman jumps direct after initial opening one bid except 1S-3C
--Cue=over under, 4+M5+m
(1C)-1D=suggestion to play NT; Nat NT; 2nd: 10-14, 3rd/4th: 14+ to 17; usually only used for hands that qualify for no other overcall
(1C)-2S=6+S 0-3H 11-16 2nd/13-17 3rd4th
(1H)-2D=6+S 0-3H 11-16 2nd/13-17 3rd4th

Opening Leads AND Leads in the Middle of the Hand

3/lo vs. Suits
4th from suits we like v. NT
ATT leads breaking new suits in middle of hand (lead lo like)
standard honors except big king vs. NT
ATT leads vs. NT in a suit that the defenders bid
Suit pref leads possible (e.g. giving ruff)
Standard honors except big king vs. NT
