Bids that Require Advance Preparation

ACBL-required pre-alerts:

2NT = either minor 6+m,
-no major,
-1st/2nd seats 12+-15 HCP,
-3rd/4th seats 14-17- HCP (17 has fewer than 5 controls),
-defenses permitted at the table.
-This convention is permitted according ACBL mid chart opening #17. "A 2NT opening bid showing an unspecified minor." http://web2.acbl.org/documentLibrary/play/Convention-Chart.pdf
-ACBL defense: http://web2.acbl.org/defensedatabase/mc18.pdf
Please note that while the defense states "weak preempt", USBF has determined it's an acceptable for the ranges here, with the exception that pairs might want to play the initial balanced doubles somewhat heavier.

1 of a major = natural;
-may have longer suit;
-4+ cards;
-1S also shows 0-3H;
-1st/2nd seats 8-9 HCP, we will pass about half of 0-1 control 8 counts;
-3rd/4th seats 14-17- HCP (17 has fewer than 5 controls);
-3rd/4th seat will either be a four card suit or balanced 5 card suit.

3-level preempts may be as undisciplined as xxxxxx.

Other opening bids, responses and competitive calls that may require advance preparation, but are not ACBL pre-alerts are listed below the general bidding style.

General Bidding Style

We play a strong diamond system with many weird openings, competing calls and follow ups.

In the 15+ HCP range in 1st and 2nd seats we have 4 calls:

2C = 5+S, 15+HCP;

2D = 5H, 4-card minor, (31) or 6H, 15+HCP;

2NT = artificial, 6+card minor, 12+-15; and

1D = 15+ art., for hands that want to ask partner what he has or any other pattern than the 2 of a minor opening patterns.

In 1st and 2nd seats in the 10-14 range, we have 4 calls below 2NT:

2 of a Major = natural;
-either a 5-card major, 4-card minor, (31) or a 6-card or longer major;
-10-11 HCP or 13-14 HCP;

1NT = natural,
-10-12 HCP,
-12 HCP has no major; and

1C = 10-14 any pattern.
-We prefer to open 2M or 1NT to 1C.
-We have the option to open 1C with a 2NT shape.

In the 8-9 HCP range we can either open at the 3-level or above or, if we have a 4+card major, we open 1 of a major. Both majors 8-9 HCP will always open 1H.

Our style is to open all 10-counts even 4333. We can upgrade or downgrade (with some exceptions like not being able to upgrade from 7 to 8 to open 1M or from 9 to 10 to open 1N). Our preempting style is to be disciplined on tricks and length, but not suit quality. Length is 6+ 3-level, 7+ 4-level and higher.

In 3rd and 4th seats, since we opened all 10-counts and most 8-9-counts already, we increase the strength requirements for our strong bids to 17+ with minimum shape. We add another forcing opening: 1C with 14+-17- and a 5-card suit unbalanced and a 5 or fewer loser hand. Our 1H, 1S, 1NT and 2NT are all 14-17- also.

1M = natural,
-4-5M,
-balanced, semi-balanced or 4441 hands.

1NT = balanced with no major.

2NT = 6m no major 14-17-. The minus in 17- is fewer than 5 controls.

We also play in 3rd seat 2M natural 5+cards 3-14 HCP (with no conventions) and no distribution requirements. In 4th seat, it's 11-14 HCP.

In 3rd/4th seats, we will pass balanced 0-13 counts with no 5-card major.

Other opening bids that may require advance preparation:

1C 1st/2nd seats = 10-14 HCP,

--balanced 2-3M 13-14,

--semi-balanced 6m 12-,
--everything else 10-14.

1D = 15+;
-artificial;

-10-12 HCP,

Competitive calls that may require advance preparation:

(1 of a suit natural) – 1NT = takeout,
-typically 10-17- HCP 2nd seat
-10-19- HCP 3rd/4th seats)

(1 of a suit natural) – Double = 15+ HCP 2nd seat;
-(1S)-X also shows a stopper;
-3rd/4th 17+-35 HCP

(1C natural) – 2D = 4+H, 5+D, 8+HCP

(1m natural) – 2H = 4+S, 5+H, 8+HCP

Opening Leads AND Leads in the Middle of the Hand

3rd/low vs. suits, 4th vs. NT from suits we like. Attitude leads possible in partner's suit. K asks count (or vs. NT unblock). A asks suit preference. K from AK when switching to xx, A from AK when switching to x. Standard honor card leads. Middle of the hand: attitude when breaking a new suit.

Defensive Signals

Primary: standard suit preference throughout the hand.
-High asks for highest absolute side suit out of the two most likely; typically T98, but if highest spot card from xxx is lower it is by agreement high.
-Low asks for lowest absolute side suit "; " 432, " ...
-Middle asks for neither; typically 567 " ...

In a situation where there are only two relevant suits and one of them is the suit we are playing a card,
-if the other suit is lower, a low card (typically 2345) asks for that suit,
-if the other suit is higher a high card asks for that suit (typically T987).

No attitude signal, we use suit preference instead.

Secondary standard count.

Discards standard suit preference.

We will sometimes give suit pref in a count situation (e.g., king lead) if, for example, dummy has a singleton. We will sometimes give count in a suit preference situation (e.g. if preference is known or irrelevant).
