Response and further bidding to 1D

1D: 11-15, min. 2 carder diamond. This bid is a kind of denial bid. If you can't open 1C/1H/1S/1N/2S/2D, then 1D is you opening bid. Always open 1maj with 5 card suit unless you have a longer diamonsuit and the majorsuit is much better than diamond.

Responses and further bidding to 2NT:

Defensive bidding:

Competitive bidding:

There is almost an endless variety of possible sequences, so it pays to have simple guidelines to prevent bidding misunderstandings:

Cuebidding RHO's suit shows values for game without clear direction for the moment. This is often used to show a game-forcing raise:

1S - (2C) - 3C = game force; usually a raise.

Negative doubles are used through 2S promising four cards (at least) in any unbid major. Bidding a major at the two level or higher shows 11 or more points and a five-card or longer suit.

If RHO makes a takeout double:

1D - (Do) - 1H, 1S = forcing, point count not limited.
                 - 2C = non-forcing (6-10 points, usually a six-card suit).
                 - 2NT = limit raise (at least 10 points) -- or better.
                 - Redouble = 10 points or more, but it is better to make a more descriptive bid of 1H, 1S, or                    2NT with the appropriate hand.
                 - 3D = Preemptive, good trump support but fewer than 10 points.

A responder's jump shift after a double is to play:

1D - (Do) - 2H, 2S, 3C = six-plus-card suit, like a weak two-bid or preemptive three-bid.

A redouble can have one of three meanings:
To play if:

  • Your side is at the four level or higher: 4S - (Do) - Redouble = Penalty:
  • The opponents double an artificial bid: 1NT - (Pa) - 2D - (Do) - Redouble = Penalty. good diamond suit;

A good hand if their double is for takeout:

  • 1S - (Do) - Redouble = 10+ points;

SOS, requesting a different suit, if your side is doubled for penalty in a trump suit at the three level or lower:

1D - (Pa) - Pass - (Do)
Pa - (Pa) - Redouble = SOS, responder can support at least two of the unbid suits.

Unless otherwise noted elsewhere, any bid or double by the opponents cancels a convention intended for non-competitive sequences.

1H - (1S) - 2NT = Natural (11-12 HCP).

If the opponents use a convention (such as Michaels or the unusual notrump), you can double to show at least 10 points, or you can cuebid one of their shown suit(s) to force to game.

1S - (2S) - 3H = game force.
                 - Double = at least 10 points, probably balanced.

Slam bidding:

Gerber 4C are used after NT bids.

Blackwood 4NT is used to ask for aces. Responses show the number of aces by steps. 5NT is then used to ask for kings; 5NT guarantees the partnership holds all four aces.

Defensive leads and signals:

This is the one area where choices are offered. The following are specified: Defensive signals when following suit or discarding are "high encourages, low discourages." Leads are top of touching honors (with choices from AKx and interior sequences). Many precision players like to use even cards as encourage, and uneven as discourage. But this should be agreed to.

Pairs must choose from the following options. Where no card is pre-marked in bold italics, pairs must mark their leads.

  • Which card is led from AKx.
  • Which card is led from xxx, xxxx or xxxxx.
  • Whether 4th best, or & 5th best leads are used.
  • Whether 3rd best is led from KJ10x, K109x, or Q109x, (and from AJ10x or A109x versus NT). Must be indicated by circling the card led.
  • Whether or not frequent count signals are given.

It is Declarer's responsibility to look at opponents' carding agreements. In the absence of a circle, cards in bold italics are presumed to be the agreement.
