POSITIVE AND TWO-WAY RESPONSES TO A
ONE CLUB OPENING
So far we have only seen 1D responses from the partner of the 1C opener.
Believe it or not, it is legal for responder to have a decent hand. Your partner may never have anything, but some players do occasionally hold 9 or more points. In this system, that constitutes a positive response. In the next several sections, we will go through the various positive responses to 1C. In some cases the positive response is just one part of a two-way bid. We will have to go through both meanings of those bids as a single entity.
In general, the following statement holds true for every one of the bids we are about to discuss : A positive response to a one club opening bid shows at least a very good eight to nine high card points and is essentially forcing to game. After an auction that starts with such a response, jumps are unnecessary unless they are used to show very specific holdings.
Several of the responses are designed to allow the strong club bidder to declare the most likely contracts. This is done by using transfer bids whenever this can practically be done without unnecessary distortion of the auction. Taken together , the bids that follow can describe a high percentage of possible responding hands with a high degree of precision.
ONE CLUB----ONE HEART or ONE SPADE
The response of one heart or one spade shows at least a five card suit. It shows 9+ HCP, although an extremely good 8 HCP hand with a strong suit (say AKJ10xx) may qualify. This last comment should not be taken as approval for the current craze for “upgrading” at the slightest excuse. If responder has an eight point hand, there is nothing wrong with starting with a negative 1D bid and then following up with a bid that shows 5-8 HCP.
When the auction goes 1C-1H or 1C-1S, opener has three basic options. 1) He can raise responder’s suit. 2) He can bid a suit of his own. 3) He can find out more about responder’s hand before making a decision.
Option number one should always be the last choice. He can always support responder’s suit later. Besides, as we shall see, an immediate raise is conventional and often is not appropriate. Option number two should be used judiciously. It should be reserved for a 1S rebid over 1H or for some unbalanced or semi-balanced hands with long clubs or diamonds. The best choice is option number three.
The two one-level bids which accomplish this objective are a rebid of 1S (over 1H) or 1NT(over either 1H or 1S). With 5+ spades, opener can rebid 1S. Responder then has a set of rebids which allow opener to judge whether there is any slam potential in the hand.
With five or more spades, opener rebids 1S. Responder now has several natural rebids and a couple of important artifical bids which define his hand more precisely. First of all, he can raise opener’s spades in several ways. He can bid 2S to show three card support and 9-12 HCP. He can bid 1NT to show four card support and 9-12 HCP. He can jump to 3S to show four card support and 13+ HCP. And he can use an artificial 2C bid and a delayed raise to show three spades and 13+ HCP. He also has two natural rebids in his own suit. A simple rebid of 2H shows 6+ hearts and 9-12 HCP. A jump to 3H shows a good six card suit and 13+ HCP. A jump to 2NT is natural and shows 13+ HCP. Finally, jumps to 3C or 3D are natural, showing 5-5 distribution and 9-12 HCP. (note- The reason responder’s 1NT is not used
as a natural bid is to avoid having the weak hand play eventual no trump contracts. The natural 2NT rebid is strong enough that we don’t worry about guiding the contract into the stronger hand.)
This leaves two artificial bids to cover remaining possible hands. Two clubs shows any hand with 13+HCP that is not covered by any of the major suit rebids. The hand may have a delayed raise, a side minor suit, or 5-3-3-2
distribution. Two Diamonds covers some of the same types of hands with
9-12 HCP. It is basically a waiting bid. It denies three spades or six hearts and will have a side minor suit or 5-3-3-2 distribution.
1C-1H or 1S-1NT
With any balanced hand (even if it contains three or four cards in responder’s suit) and with many semi-balanced hands, opener should rebid 1NT. That is for three reasons. First, it ensures that all no trump contracts will be declared by the strong hand. Second, it takes up very little bidding room. Most importantly, just as with the 1S rebid, when opener rebids 1NT the system provides a set of continuations by responder that the opener can use to immediatelyjudge whether the partnership should be looking for slam or merely trying to settle on the best game contract.
In each case the key continuation is a completely artificial 2C bid. If responder’s first rebid is 2C, it shows at least 13 HCP and indicates that slam is at least worth exploring. All other non-jump rebids show 9-12 HCP. When responder makes one of these bids it usually means that slam is not likely. Unless the 1C opener has extra strength or the distribution provides extra trick-taking potential, the auction will merely be a search for the best game.
The continuations after both the 1S and 1NT rebids include several similar bids . Rebids of responder’s major show 6+ card suits. Raises are basically natural. Double jumps in new suits are splinter bids.
Both schemes feature the artificial 2C rebid to show 13+ HCP. They have two other artificial bids in common. The 2D bid is a waiting bid.After opener’s 1NT, it showsfour cards in the opposite major. A bid of the opposite major is a waiting bid that denies four cards in that major. This use of 2D and the other major is not a whimsical affectation. It means that the strong hand will be the declarer any time there is a 4-4 fit in that suit. Suit bids after a waiting bid show 4-card suits or stoppers for no trump.
Transfers are used in both schemes to show second 5-card suits in hands with 9-12 HCP. That is, a 2NT bid shows 5+ clubs, a 3C bid shows 5+ diamonds, and 3D shows 5+ hearts (only if responder’s first bid was 1S.) Responder can then make a third bid to show his short suit, completing an accurate description of his hand. We can use transfers here because the 1C opener has already bid no trump, and all no trump contracts will be played by the strong hand. One special feature of these secondary transfers is the ability of responder to make a transfer back into his own suit at the three level. This shows a semi-solid suit and 13+ HCP. A natural jump in his suit can now show a solid suit and 13+ HCP. This is slightly altered when the auction goes 1C-1H-1S. Then we have to use the 2D waiting bid to handle a secondary 5-card diamond suit, using a natural 3C bid to show 5+ clubs. This gives up the transfer into diamonds in order to keep the jump rebids in hearts consistent with those in spades. These two bids are more likely to be helpful in finding find a good game or slam than a transfer into diamonds.
inquiry in a new suit, just as with TAB. The answers are the same as those
in response to a second TAB bid. 3NT and game bids in one of responder’s
suits are signoffs.
To avoid a trump asking sequence, opener must bid NT or a suit of his
own at his first and 2nd bids. After that, bidding is natural.

♣ AQxx ♣ Kx 4C (ask) 4S (2nd rd. control)
5D (ask) 6C (1st rd. control)
REBIDS OF 2C and 2D AFTER 1C- 1H or 1S
When opener has a long minor suit and 17+HCP and gets a positive response of 1H or 1S to his 1C opening, he has a choice of rebids.
With only a five-card suit, a 1NT rebid is generally the best choice,
assuming at least a semi-balanced hand.Even with 5-4-3-1 distribution
and a singleton in responder’s suit, a 1NT rebid may be the best way to
get useful information on responder’s hand and may also right-side any
no trump contracts.
A rebid of 2C or 2D, therefore, tends to show at least a six-card suit.
After a lot of exploration involving relays and other artificial continuation
schemes to describe responder’s distribution and point range, I finally came back to one that is fairly natural. It will use the cheapest second bid by responder (2D over 2C; 2H over 2D) as a waiting bid. Most other non-jump
bids will be natural, and a few jump bids will show specific hands.
Responder usually will not try to indicate extra values immediately since he is in a game-forcing auction, He will have later opportunities to indicate slam interest (by supporting opener’s suit at the four level, cue-bidding a side suit, making a splinter bid, etc.). He can rebid his suit with six, bid a second four or five card suit, or support opener’s minor with three.The waiting bid will be used for many hands in the 9-12 HCP range. It will be used for any hand with no second biddable suit, no rebiddable six-card major, and less than three-card card support for opener’s minor. A rebid of 2H over 2D be may simply show a 5-3-3-2 hand with nothing else to bid. Another heart bid is needed to guarantee a six-card suit.
There are basically only three immediate strong second bids available to
responder. One is 2NT. This will guarantee honors in all suits outside
opener’s minor and show at least 13 HCP. Opener will be able to ask for
the exact range (in steps) by bidding 3C (1st step= 13-14, 2nd= 15-16,
3rd=17-18, etc.). The second strong bid is a jump rebid in opener’s major, which shows at least 13 HCP and a very good six or seven card suit.
The third is an immediate splinter , showing at least good three-card support for opener’s suit, shortness in the bid suit, and enough strength to invite slam..
These bids may not be very sophisticated, but they should cause almost no

ONE CLUB----ONE NO TRUMP One of the major design flaws of the Precision Club is the use of 1C-1NT to show a balanced hand with 8-10 HCP. Of course, Precision was designed for simplicity, and this bid is simple and easy to remember. Unfortunately, 1NT is probably the most likely positive response in the whole system. The result is that a great number of no trump contracts are declared by the weak hand, with the strong hand exposed as dummy. There is a solution for this
problem, which will be explained in the next section. Suffice it to say,we have a better way to bid balanced 9-12 HCP hands.
Our new improved 1NT response to a 1C opening shows a balanced hand with 13-15 HCP.With that much strength, there should be no concern about responder declaring the hand. Our main problem will be deciding if slam is a good idea.
The continuations are quite straightforward. Opener bids 2C as Stayman.
Bids of 2D, 2H,and 2S are all natural, showing 5+ card suits. A 2NT bid shows a 5+ card club suit.
At this point any number of continuation schemes will work quite nicely.
One is simply to make all of responder’s bids natural, with no attempt to artificially define strength or trump quality. My preference is to try to get some useful information about responder’s holdings in prospective trump suits. This involves making opener’s natural suit bids double as asking bids. Responder’s answers most closely resemble the Ogust convention’s method of describing weak two bids.
When opener bids 2C (Stayman), responder’s reply will either be a
transfer showing a 4-card suit or a bid denying a major but describing his hand’s strength. To be specific, a 2D reply shows four hearts. Responder may also have a second suit. 2H shows four spades. It denies four hearts, but the hand may have a four card minor. 2S shows no major and a minimum (13-14 HCP) The hand will have one or two minors. 2NT shows four clubs, no major and a maximum (15 HCP). 3C shows four diamonds, a maximum, and necessarily 4-3-3-3 distribution. If opener has a fit for responder’s guaranteed suit he bids it. This bid also asks about the quality of the agreed suit. If no trump fit is found in the transfer suit, opener bids a different suit. This asks about responder’s holding there. If no suit fit can be found, opener can sign off or try for slam in no trump.
The same inquiry process takes place when when opener bids a 5+card suit instead of bidding Stayman. Responder’s reply indicates his holding in the suit. Depending on the response, his exact strength may be established later if necessary.
The instruments for all this investigation are modified versions of the Ogust convention. Unfortunately, three slightly different versions are needed- one for suits in which responder has guaranteed 4-card length and two others for suits in which his length is unknown. I have tried to make the answer schemes are as similar as possible to minimize memory strain.
You’ll notice that I haven’t given the exact definitions for responder’s answers. That’s because Ogust is somewhat subjective. It uses terms like “good hand/bad hand” and “good suit/bad suit”. In general, our responder will describe his support as “poor”, “fair”, “good”, or “excellent”. He does this in steps. Those terms will have slightly different definitions in our three versions of the answers. The pattern will be very similar. The steps will begin with the worst possible hand and culminate with the best. There will also be a follow-up method to get more exact information if slam is in the picture.
“poor”, ‘fair” or “good” support. Others are free to use their own standards.
First,when there is a known 4-4 fit:
1st step = poor support (Jxxx or less)
2nd step = fair support (Qxxx, Kxxx, Axxx)
3rd step = good support (QJxx,KJxx, AJxx)
4th step = excellent support (KQxx, AQxx,AKxx)
When opener bids a different suit, needing 4-card support:
1st step = lacking 4-card support
2nd step =poor 4-card support (Jxxx or less)
3rd step = fair 4-card support (Qxxx, Kxxx, Axxx)
4th step = good 4-card support (QJxx, KJxx, AJxx)
5th step = excellent 4-card support (KQxx, AQxx, AKxx)
When a 4-4 fit is established, opener can ask about responder’s overall strength by making the cheapest continuation bid. The first step shows a minimum(13-14 HCP);the second step shows a maximum(15 HCP).
When opener bids a 5+ card suit:
1st step = poor support (xx, Hx,)
2nd step = fair 3-card support (xxx,Hxx)
3rd step = poor 4-card support (xxxx)
4th step = fair/good 4-card support (Hxxx)
5th step = excellent 4-card support (HHxx)
H = high honor- A, K, or Q
When the support is poor , opener can ask about support in a second suit.The same answers would apply.
When responder’s answer establishes at least an eight card trump fit, opener can use the next cheapest bid to ask about general strength. In assessing strength, “minimum”should mean 13 to an average 14 HCP. “Maximum” should mean 15 or possibly a very good 14 HCP-a hand with lots of 10’s and 9’s.
If opener denies four of responder’s suit but shows a four card suit of his own, the same basic standards apply. However, responder hs not guaranteed
four card support. Therefore, the first step denies four cards in the bid suit.The other responses all show varying degrees of four card support.
When there is no hope for a 4-4 fit but slam in no trump is possible, opener can bid 2NT instead of a suit.(If responder bids 3C to show four diamonds, he can bid 3H) This bid asks about strength only. The answers are simple:
1st step =13 2nd step= 14 3rd step=15 If you’re into upgrading, you can add A fourth step for a “super 15” with lots of intermediates. You can also promote a lower answer one step, but only with very good intermediate cards.
When opener bids a 5+ card suit rather than bidding Stayman, our answers have to be adjusted. Responder may have only two cards in our suit. The first step has to account for that holding. We then have to have responses for three card and four card support. The response chart shows those responses.
