I SLAM TRIES IN SUIT AUCTIONS: CUE-BIDDING

Point count is not very accurate with unbalanced hands that have a fit. Tricks and controls, or controls with distribution and lots of trump are the hand types that make slam easily with less than 33 points. For example, the following two deals both make slam and neither has the required points.

West East West East
!S AJ
!H KQ10652
!D A3
!C 85
!S KQ10987
!H A97
!D 965
!C 6

!D A7652

I. WHEN PARTNER OPENS 1NT- ADD THE POINTS UP

It takes 33 points to make a small slam and 37 to make a grand. Do you have them? When you have a good balanced hand of your own, add your points to partner’s possible minimum and maximum counts to see what the possibilities are. The following table shows your bids over 1NT, the point ranges assume a 15-17 1NT opener.

Bid Your HCPs Meaning
4NT 16-17 Please bid 6 with a maximum
5NT 20-21 Please bid 7 with a maximum, else bid only 6
6NT 18-19 This is what we can make (you may not raise)
7NT 22+ This is it.

BALANCING at the two level

      2 Comments on BALANCING at the two level

When the opponents have stopped in a part score at the one or two level, should you pass it out or bid? The answer depends on what contract they have stopped in and what kind of hand you have yourself.

Let’s look at the classic situation where they are in two of a major:

1!H Pass 2!H Pass

Pass ?

First of all, they have less than 26 pts, probably less than 25; their range is roughly 19-24; this leaves plenty of high cards for our side. The mathematics of suit distributions indicate that if they have an 8 card fit, we usually have one as well. Thus if we have an 8 card fit and roughly half the high cards, perhaps we should try to play the hand.

Balancing at the One Level

I. Definition of the Word BALANCING

The term balancing means taking a bid other than Pass after two preceding passes. In other words, balancing is an attempt to prevent the opponents from playing the hand. For example,

1 !D Pass Pass        and it is your bid

Saying Pass here would be the final decision of the auction, while bidding means there have to be at least 3 more bids. You’d better be right to pass!

Competing over the Opponents 1NT

      1 Comment on Competing over the Opponents 1NT

I. Competing over 1NT only requires weak 2-bid strength

What are your side’s chances of making a game when an opponent opens 1NT? Well, there are only 24 high card points left, so even if your side has all of them, which is unlikely, some distribution points will be required to get your side up to the 26 points needed for game.

So if you bid over their 1NT, it is because you want to contest the part-score.

When the opponents open 1NT and everyone passes, your chances of getting a good score are not likely. If you can make 110 your way in a major and they go down one or make it, then you are wrong to let them play it. If they are making and you are down one non-vulnerable, you are also wrong to pass it out.

When it is their hand for game, you take away their ability to bid Stayman or transfer by bidding. Also if they double you, frequently the penalty they collect is smaller than the plus score they would get for their game.

Does a Negative Double of 1D show both majors?

      7 Comments on Does a Negative Double of 1D show both majors?

Another recent question was …

Does a negative double of 1♦ after partner opens 1!C show both majors?

The standard treatment is that a negative double of 1♦ after partner opens 1!C shows both majors, usually 4-4. Longer and unequal lengths such as 5-4 or 4-5 are possible with a weak hand.

Here is why the double needs to be both majors: Due to the way Bridge scoring works, it is extremely important to find your eight-card major suit fits. In a competitive auction you need to do this as quickly as possible. This means that if you have only one major, even if it is only four-cards long, you must bid it right away so partner knows which one you have. When the opponents overcall 1♥, you can use a negative double to show four spades and bid 1 ♠ to show five because, unlike after a 1♦ overcall, there is no ambiguity as to which major your side holds.

Preempting

      45 Comments on Preempting

One of the most effective strategies in competitive bidding is the preempt. When you have a long strong suit and not many points you can start the bidding at the 3 level with a 7-card suit and at the four level with an 8-card suit. This makes life very difficult for the opponents since they have lost the space needed in the bidding to find their own correct contract and most of the time doubling you will not be profitable enough.

Using the 2 level for pre-empting as well, makes it even harder on the opponents and only gives up bidding space on those very strong (22+) one suited hands that you almost never get. The bid of 2 clubs is used for all your hands of 22+ (except 21-22 balanced which are opened 2NT).

I. Getting the Strong Notrump Hand to Declare the Major

One of the primary objectives of bidding is to find an eight card major suit fit and play in it at the appropriate level. Jacoby transfer bids make it easier to describe hands with five and six card major suits when partner opens 1NT.

This is how it works, you bid the suit below your long major suit:

2 !D says “I have 5+ hearts”
2 !H says “I have 5+ spades”

Now partner bids your suit, 2!H or 2!S . This has transferred the declaring of the major to partner’s stronger hand. It is an advantage to have the hand with more high cards make the last play at trick one.

BASIC BIDDING REVIEW: — Competition

. When the Opponents Open

Annoying, isn’t it? You had just decided that you were going to open the bidding with 1!D, when your opponent opens 1!S in front of you. What to do?

When both sides are bidding, your objective is to get the best score possible. Game is unlikely, unless there is a good distributional fit. Finding an eight card major suit fit is still very important, since playing in a major will usually produce the best score.

Having a hand you would have opened is no reason to bid now. Your strategy has changed. There are only four reasons to bid once the opponents have opened:

  1. Balance of the Power. Our side might have most of the strength.
  2. Lead Direction. It could be important to tell partner what to lead.
  3. Sacrifice. We may have a good sacrifice versus their game, slam, or partscore.
  4. Obstruction. Our bidding may make it hard for them to get to the right spot.

The tools at our disposal for competing once the opponents have bid a suit are:

  1. The no-trump overcall
  2. The simple suit overcall
  3. The take-out double
  4. The jump overcall
  5. Various 2 suited bids

BASIC BIDDING SUMMARY after 1 of a suit

      128 Comments on BASIC BIDDING SUMMARY after 1 of a suit

I. What Is Your Objective?

One of the primary objectives of bidding is to find an eight card major suit fit to play in. The other main objective is to determine how many points the partnership has. These are the two questions you should ask yourself every time it is your turn to bid:

  1. Do we have an 8 card or longer major suit fit ?
  2. Do we have the 26 points needed for a game ?

Once either partner knows that there cannot be 26 points, it is that player’s job to stop in a makable contract. This usually means passing, or making the cheapest bid in a previously bid suit. Conversely, if you know your side has enough points for a game, do not make a bid that your partner can pass!
