The 1 ♣ opening (version 5)

Requirements of the 1 ♣ opening

 

The 1 ♣ opening is used under the following conditions:

 

- 16+ HP, any distribution possible, including also a balanced distribution

 

There are two exceptions:

     à 2 shows 23-24 HP and a balanced hand in one of its variants

     à Vulnerable and as a general rule in fourth seat: 1 NT = 14-16 HP

 

- If one has 7 controls (therefore 3 aces and a king) and an offensively oriented hand, one can also open 1 ♣ with only 15 HP.  Also 1 ♣ is possible with a very good 15 HP;

   e.g. ♠ AKJ1096/ A/ QJ109/ ♣ 65. The reason:  Many tricks, many 10s and 9s. Also one can open with 15 HP if one has at least a 6 card suit which is playable opposite a singleton, and if one also has a singleton or a void.

 

- One can also open 1 ♣ with extreme 2 suiters with the points in the long suits; if one is vulnerable and the opponent non-vulnerable, it is often better with such hands to open 1 in a suit and follow later with a reverse bid.  Since if the opponent intervenes, which he can do with no trouble at all when non-vulnerable, it often becomes difficult to show the hand.  Further the danger exists that in a competitive auction, partner might be inclined to expect too many defensive values in our hand.  On the other hand if one is non-vulnerable and the opponent vulnerable, it is usually correct to begin with 1 ♣.

 

- We open strong hands with 4-4-4-1 also via 1 ♣; with an honour in the singleton (ace or king) we treat it as a balanced hand as a rule and bid No Trumps in the second round of bidding.

 

- But under some circumstances a hand even with 16 HP only just qualifies for a 1 ♣ opening. E.g. with ♠ KQ42/ QJ/ AQJ62/ ♣ J9 one can also open 1 especially since the value of the points in the shortages are of doubtful value and one has a problem-free rebid.

 

And do not forget:

 

In the following hands with 16 or more HP, one does not open 1 ♣:

 

à 23-24 HP, balanced distribution (à one opens 2 Multi)

 

à 14-16 HP with balanced distribution without a 5 card major vulnerable and as a general rule in fourth seat: 1 NT


 

 

 

The responses after the 1 ♣ opening:

 

To begin with:  Because 1 ♣ is an artificial, unlimited opening, pass by partner is not possible.  There are basically two types of responses:  Weak responses on the one hand and strong bids (from at least 8 HP) on the other hand, responses therefore which guarantee game. It is therefore possible at the 1 level with the first bid to force to game.  Perhaps you ask yourself the question why 16 HP (rarely a very good 15 HP) with the opener and 8+ HP with the responder is sufficient as a rule for game.  Now, experience teaches that as soon as an 8 card fit is found, as a rule enough distribution values exist.  With No Trumps we protect ourselves partially, in that we open 1 NT vulnerable as well as in fourth seat with 14-16 HP, the risk is a little greater with non-vulnerable openings in first, second or third seat because here 1 NT shows 10-12 HP and 1 ♣ is opened with 16 HP.

 

Opener

Responses

Meaning of the bids

1 ♣

1 :

Negative, 0-7 HP, no distributional hands with 3 Italian controls (for with 3 controls we bid as if we had with 8+ HP) (Italian controls:  Ace = 2, king = 1); with balanced hands only the high card points are decisive.

 

1 :

Variant 1:  5+ (no suit quality requirement!), 8+ HP, unlimited

Variant 2:  15+ HP, balanced distribution without a 5 card major

 

1 ♠:

5+ ♠ (no suit quality requirement!), 8+ HP, unlimited

 

1 NT:

Balanced distribution, (8)9-14 HP, no 5 card major, 5 card minor with 3/3/2 in the side suits

 

2 ♣:

At least 5 ♣ (no suit quality requirement!), 8+ HP, any distribution allowed, but not balanced (5/3/3/2) distribution

 

2 :

At least 5 (no suit quality requirement!), 8+ HP, any distribution allowed, but not balanced (5/3/3/2) distribution

 

2 :

8+ HP, exactly 5-4 or 4-5 in the minors

 

2 ♠:

12+ HP, black singleton, therefore 1-4-4-4 or 4-4-4-1

 

2 NT:

12+ HP, red singleton, therefore 4-1-4-4 or 4-4-1-4

 

3 ♣:

Black singleton, therefore 1-4-4-4 or 4-4-4-1, 8-11(12) HP

 

3 :

Red singleton, therefore 4-1-4-4 or 4-4-1-4, 8-11(12) HP

 

3 :

Any solid 7 card suit, with or without controls in the other suits.  The suit must be so solid that it is playable opposite a singleton (as a rule AKQJxxx).

 

3 ♠:

Any solid 8 card suit, with or without controls in the other suits.  The suit must be so solid that it is playable opposite a singleton (as a rule AKQxxxxx).

 

3 NT:

Any solid 9 card suit, with or without controls in the other suits.  The suit must be so solid that it is playable opposite a singleton (as a rule AKQxxxxxx).

 

4 ♣:

4-7 HP, broken 8 ♣, points are mainly in this suit

 

4 :

4-7 HP, broken 8 , points are mainly in this suit

 

4 :

4-7 HP, broken 8 , points are mainly in this suit

 

4 ♠:

4-7 HP, broken 8 ♠, points are mainly in this suit

 

4 NT:

Ace-ask  (the auction probably ends in 7 NT)

 


 

 

 

Positive bids in a suit show basically 8+ HP.  If one possesses an ace and a king, and these are either in one or in both long suits, this justifies a positive bid.  Examples: 

 

1.) ♠ AK9543 8 1095 ♣ 632                                 1 ♣ - 1 ♠

2.) ♠ K10943 7 A1087 ♣ 765                               1 ♣ - 1 ♠

3.) ♠ 3 A9875 K8732 ♣ 87                                               1 ♣ - 1

4.) ♠ AK765 10763 754 ♣ 5                                 1 ♣ - 1 ♠

 

A response of No Trumps denies a 5 card major, without regard to the quality of the suit!  With it one knows that responder bidding No trumps has a distribution of 4/3/3/3, 4/4/3/2 or 5/3/3/2 with a 5 card minor and (8)9-14 HP.  Actually one should not bid 1 NT with a 5/4/2/2 distribution; our system allows us with a strength of 8-11 HP to describe such hands exactly, and this on low level! 

 

 

 

The bidding after 1 ♣ - 1 ♦

 

The response of 1 shows that responder is too weak to make a positive response.  The bid is conventional and shows 0-7 HP (nothing to do with the suit).

 

Basically the subsequent bidding continues naturally after this weak response of 1 .  There are however two exceptions:  The bid of 1 by opener is conventional as is 2 ♣.  1 can be natural or a relay (after that responder usually uses the relay of 1 ♠), 2 ♣ shows a very strong hand.

à Variant 1:  Natural, 16-19(20) HP, maximum of 7½ tricks, 5+

à Variant 2:  16-19(20) HP, maximum of 7½ tricks, 5+ ♣

à Variant 3:  19-20 HP, balanced distribution without a 5 card major (rebids 1 NT after partner’s relay of 1 ♠)

à Variant 4:  25-26 HP, balanced distribution with or without a 5 card major (rebids 2 NT after partner relay of 1 ♠)

!

1 ♠:

 

Natural, 16-19(20) HP, maximum 7½ tricks, 5+ ♠, non-forcing

 

1 NT:

 

16-18 HP, vulnerable and as a general rule after openings in fourth seat 17-18 HP, balanced hand without a 5 card major, 5 card minor allowed; conceivably any 4-4-4-1 distribution with an ace or a king in the singleton suit.

 

2 ♣:

 

Relay, used with hands forcing to game (forcing to the 4 level in a minor), asks partner to relay 2 with 0-1 controls, 2 with 2 controls and 2 ♠ with 3 controls and flat hand

Meaning of the bids

 

2 :

 

19-22 HP, 8-8½ tricks, semi-forcing, good suit with 5+ cards, one or two suiter, balanced distribution with a 5 card major possible with 19-20 HP

 

2 ♠:

 

19-22 HP, 8-8½ tricks, semi-forcing, good ♠ suit with 5+ cards, one or two suiter, balanced distribution with a 5 card major possible

 

2 NT:

 

21-22 HP, balanced hand, may have a 5 card major

 

3 ♣:

 

19-22 HP, 8-8½ tricks, semi-forcing, good ♣ suit with 6+ cards

 

3 :

 

19-22 HP, 8-8½ tricks, semi-forcing, good suit with 6+ cards

 

3 :

 

Very strong, sets suit as trumps, even if partner has a void.  Partner is requested to make a first round cue bid (with a void only if he has at least two trumps). 3 NT shows that he has a second round control, which 4 ♣ can ask for. 4 denies the possession of a first or second round control.  In this case, opener can make a modified Control Asking-Bid (1st step = no third round control, 2nd step = doubleton, 3rd step = Qxx). 

Example: 4 ♠ with ♠ 65/ AKQ107543/ AKJ/ ♣ -

!

3 ♠:

 

Very strong, sets ♠ suit as trumps, even if partner has a ♠ void.  Partner is requested to make a first round cue bid (with a void only if he has at least two trumps). 3 NT shows that he has a second round control, which 4 ♣ can ask for. 4 ♠ denies the possession of a first or second round control.  In this case, opener can make a modified Control Asking-Bid (1st step = no third round control, 2nd step = doubleton, 3rd step = Qxx). 

Example: 5 with ♠ AKQJ1098/ 4/ KJ3/ ♣ AK

!

3 NT:

 

Solid ♣ or suit (7-8 cards) in the style of Gambling 3 NT (however with extra values in the other suits (to be passed as a rule; for subsequent bidding compare this with the 3 NT opening))

 

4 :

 

To play, stronger than a Namyats opening (4 ♣)

 

4 ♠:

 

To play, stronger than a Namyats opening (4 )

Example: ♠ AKJ10654/ KQ6/ A7/ ♣ 5

 

 

With the second rebid, the bidding depends on the first rebid of opener, but also on one’s own strength.  Opener’s relays of 1 and respectively 2 ♣ are absolutely forcing, and also his rebids of 3 or respectively 3 ♠.

 

If opener made a natural, not forcing bid, responder passes as a rule with 0-4 HP provided that he has something like a balanced distribution (with or without a fit).  With unbalanced hands and a fit, one is a little more aggressive and shows this fit with at least 4 HP.  Thus one bids for example with   ♠ Q76/ 9/ Q543/ ♣ 109865 after 1 ♣ - 1 - 1 ♠ à 2 ♠, with ♠ Q963/ 9/ Q54/ ♣ 109865 even à 3 ♠.   However one passes after this sequence with a balanced hand such as ♠ QJ5/ 765/ J107/ ♣ 7632. One treats a hand with 4 HP also like a similar one with 5-7 HP if one possesses an ace.


 

 

 

The bid 1 ♣ - 1 - 1 ♠ is natural and limited.  If responder has 5-7 HP and a fit, he should show this; this counts also even if he possesses a suit of his own.  One introduces one’s own suit with 5-7 HP only without a fit (and passes with weaker hands).  One may bid aggressively (also with jumps) with a good fit (4+ cards) and a singleton or a void as well as 5-7 HP; with a double jump one can also make a splinter (e.g. after 1 ♣ - 1 - 1 ♠ - 4 ♣ with à  ♠ J1098/ 93/ AJ10987/ ♣ 5).  Somewhat special is 1♣ - 1 -1 :   The bid can be natural or a relay; responder is expected to now bid 1 ♠, apart from the following exceptions:

 

1 ♣

1 ♠:

To 99% compulsory relay.  That can be disregarded only with a weak hand (0-5 HP) and broken suit in ♣ or , with a 6 card major and 0-3 HP or with a weak hand with 5-5 in the majors or respectively the minors.

Requirements of the bid:

-   4/3/3/3, 4/4/3/2, 5/3/3/2, 6/3/2/2 with 6 card minor possible (then however (18)19 HP)

 

Specific features in the subsequent bidding

 

Note the following in the subsequent bidding:  If one has a 5-2 or 5-3 distribution in the majors, one bids via a transfer.  However in exceptional cases, Stayman with 5-3 is also possible, indeed if one has a gap in another suit and is in search of a good 5-3 or 4-3 fit.  Only with a 5-4 distribution does one go via Stayman, and then when one has (5)6-7 HP.  With this variant one bids after 2 the 4 card major at the 3 level (Smolen Convention) or respectively bids game if partner shows a 4 card major after Stayman.  If one has 4-5 HP as well as 5-4-distribution in the majors, one first transfers into the 5 card suit and subsequently bids the 4 card suit; this bid is an invitation to game.

And now some details of the transfer bids

 

Transfer bids are to be carried out.  Jumps in the transfer suit should be only be made in exceptional cases (shows a maximum and a good 4 card fit) because partner can be very weak.  A new suit also shows a maximum, a good 4 card fit and denies values in the bid suit. 2 NT shows 20½ HP (thanks to a good 5 card suit) and a three card fit with two of the top three honours; in pairs tournaments, this bid is to be used only in exceptional circumstances, on the other hand always in team contests.  After all these deviations from the execution of the transfer, the repetition of the transfer suit is a re-transfer that is to be obeyed.  If the opponent doubles the transfer, then partner only executes it with a fit (otherwise he passes, redouble denies a fit and shows at least two high honours to four in the transfer suit).


 

 

 

If responder shows a second suit at the 3 level after his transfer, then the further bidding develops as follows:  Suit bids at the 3 level are cue bids with a fit in the second suit, suit bids at the 4 level are cue bids in that major suit fit.  The bids of 3 NT and 4 of a major are natural and deny interest in more.  An example:

3 //♠:

4 ♣//:

 

Cue bid with ♠ fit, maximum

4 ♠:

 

To play (therefore ♠ fit and not maximum)

 

 

After such a cue bid at the 3 level, 3 NT is to play.  One probably sought a 3 card fit in the first mentioned major.

6 ♠, mild slam interest, normally pass, 7 HP, no shortage (otherwise one would have made a splinter bid), intermediates, problem with top honours

 

 

 

 

Transfer into a minor

 

With 2 ♠ or respectively 2 NT, one transfers to ♣ or respectively .

 

Normally one simply carries out the transfer.  If one says after 2 ♠ à 2 NT or respectively after 2 NT à 3 ♣, this shows a maximum and at least a 4 card fit or at least Axx or KJx (in partner’s minor); this allows partner, in any case, to bid 3 NT.

So far the problem-free bids.  If opener after this transfer into a minor does not bid the requested minor suit, but rather with 1 NT - 2 ♠ - 2 NT or respectively with 1 NT - 2 NT - 3 ♣ shows a fit and a maximum, then responder bids his long suit if he wants to play here.  However, he also has other possibilities:

If opener carries out the transfer into the minor normally and responder now bids a major suit at the 3 level, this is natural and shows a 6-4-hand with a 4 card major and is forcing to game.  If one has such a distribution as responder and not enough points to force to game, one transfers into the minor and then passes (for this one normally has 0-4 HP and a good minor suit, otherwise one would have immediately bid 2 ♣ after 1 ♣ - 1 - 1 ).

 

If responder has, as described above, shown a 6 card minor with a 4 card major, 3 NT or respectively the raise of the major suit to the 4 level is to play, other bids are cue bids.

 

If responder, after transferring to a minor suit, jumps in a new suit after opener’s response, this is a splinter - provided that the bid does not have a special meaning.

 

 

 

The opponent intervenes after 1 No Trump

 

If the opponent intervenes after the opening 1 ♣ -1 - 1 - 1 ♠ - 1 NT in a natural or artificial way, we continue - as far as nothing else is described later- as follows:

 

Double against natural intervention

Negative double, one wants to play a part score, shows the other suits, (0)1-4 HP

Double against artificial intervention

4-7 HP, optional

Suit at 2 level after intervention

Natural, 5+ cards, 0-4 HP

Cue of the opponent’s suit

5-7 HP, Stayman without a stopper in opponent’s suit

Suit at the 3 level lower in rank than that of the intervention

5-7 HP, 5+ cards, natural, forcing

Suit at the 3 level higher in rank than that of the intervention

5-7 HP, 5+ cards, natural, forcing, no stopper in the opponent’s suit (otherwise go though 2 NT and then for example 3 ♠)

2 NT

Lebensohl, partner must bid 3 ♣; after that the bid of a suit lower than the intervention suit is to be passed, the cue of the opponent’s suit is Stayman with a stopper in the opponent’s suit and 3 NT is to play (with a stopper in the opponent’s suit), a higher ranking suit than the intervention suit is natural, showing a stopper and 5-7 HP

3 NT

(5)6-7 HP, balanced, no stopper in the opponent’s suit

 

Because we play negative doubles against natural interventions, opener doubles after pass if he has 2-3 cards in the opponent’s suit.  If partner now bids, he is weak.

 


 

 

 

If the opponent intervenes in the transfer, double shows 4-7 HP and the suit used for the transfer bid, bid of the transfer suit shows (0)1-4 HP and is like a negative double (therefore take-out against the announced suit of the opponent), all remaining bids are identical to above in the defence against natural intervention (therefore Lebensohl etc.).  The direct bid of the opponent’s suit at the 3 level is therefore Stayman without a stopper, after 2 NT on the other hand with a stopper, both times with (4)5-7 HP.

 

If the opponent doubles when we reach 1 NT, redouble is a transfer to ♣ (5+ ♣), 2 ♣ shows 5+ , 2 shows 5+ , 2 shows 5+ ♠.  These transfer bids say nothing about strength.

 

If one passes, opener must redouble.  This redouble is passed if one believes partner can make 1 NT (so from (2)3 HP), otherwise one bids economically 4 card suits up the line until a fit is found.  Please note:  We take no notice of the meaning of the opponent’s doubles, therefore we always play the same.

 

It is a little different however if the double comes in fourth seat; here we also take no notice of the meaning of the double!

There are countless conventions with two suiters against 1 NT. We always behave the same against these, regardless of whether we have opened 1 NT, or whether we have bid 1 NT after 1 ♣ - 1 - 1 NT or after 1 ♣ - 1 - 1 - 1 ♠ - 1 NT: The only difference lies in the strength needed for these bids - logically, one must be more careful after opening 1 NT with 13-15 HP than in the case of the other two variants.  Details on our defence against conventional bids after 1 NT can be found in the 1 NT Opening chapter.  (Digression:  After 1 NT superweak (10-12 HP) it should be noted that double against suit interventions is penalty).


 

 

 

If the opponent doubles our Stayman bid, we pass without a stopper in ♣.  All other bids are like after an undisturbed Stayman, however the bids show a ♣ stopper.  If opener passes, his partner must redouble.  Now opener passes if he has a good 5+ ♣ suit, otherwise he bids again like after undisturbed Stayman, with the additional information that his partner knows however that opener has no ♣ stopper.  The direct redouble by opener denies a 4 card major and shows 4 ♣.  Partner can now pass with ♣ support if need be.

Suggestion for penalty double

 

If we use a transfer bid and the opponent doubles this, we accept the transfer only with a fit.  Redouble by partner after our pass requests us to complete the transfer.  Redouble by the opener shows a good 5 cards (or exceptionally two top honours to four) in the bid and doubled suit, as a rule it denies a fit in partner’s suit.

 

If the opponent bids a suit after our transfer, we only carry out the transfer with a fit.  The bid is competitive and says nothing about our strength.  As a rule, we have a 4 card fit (Law of Total Tricks).  If opener passed after the intervention, his partner can repeat the transfer (so if one has transferred with 2 , 3 is now not natural, but rather a re-transfer).

 


 

 

 

The bidding sequence after 1 ♣ - 1 ♦ - 1 ♥ - 1 ♠ - 2 NT:

 

This bid shows a balanced hand with 25-26 HP.  The further bidding sequences are absolutely identical to those after the opening à 2 followed by 2 NT à except that the further bids assume fewer points.  Logically one speaks from 0 points, in the case of slam ambition one knows from experience that 6 NT makes from 33 HP, 7 NT from 37 HP.  We refer therefore to the sequences described there.  This applies also to handling intervention, should it suddenly occur at this stage.

4 :

4 ♠:

Generally it is considered that in the second bid of responder a fit should be shown, if he has one (instead of first introducing a suit of his own).


 

 

 

The bidding sequence after 1 ♣ - 1 ♦ - 1 NT:

 

 

With 1 ♣ - 1 - 1 NT, opener shows a balanced hand without a 5 card major and with 16-18 HP or respectively 17-18 HP when vulnerable and as a general rule after openings in fourth seat.  Because of the limitation of the hand, responder takes command.  Invitations to game should only be made with (6)7 HP, unless one has the necessary distribution (in other words a long suit).  Without a long suit (5+ cards), one should pass with 0-6 HP as a rule.

 

Note the following specialty in the subsequent bidding:  If one has a distribution of 5-2 or 5-3 in the majors, one bids via a transfer (opener does not of course have a 5 card major).  Only with a distribution of 5-4 does one go via Stayman whereby one can also be very weak.  With a balanced hand, one should pass with 0-6 HP as a rule, except if one has 5-4 or 4-5 in the majors or has a distribution with which one can pass any of opener’s responses to Stayman.  With 7 HP on the other hand one should invite - one has sufficient points for every contract at the 2 level; with 6 HP, one must be aware that one plays against the field if one now uses Stayman because most players pass with natural systems.

At least 5-5 in the majors, (4)5-6 HP, pass or correct, partner places the contract at the 3 level (or game with a maximum and a double fit).

 

 

3 ♠:

7 HP, at least 5-5 in the minors, invitational to 3 NT or 5 in a minor (with a minimum and a problem in one or both majors, the opener can bid a minor at the 4 level).

The bidding after 1 ♣ - 1 ♦ - 2 ♣:

 

 

The sequence 1 ♣ - 1 - 2♣ is artificial. 2 ♣ is a forcing relay (nothing to do with ♣).  A major suit bid after a relay of 2 , 2 or 2 ♠ now becomes forcing to game, the bid of a minor forcing to 3 NT or 4 in this minor.

If the opponents first intervene at this time, we play double as take out.  The remaining bids are natural and force to game.  Because the double is take out (à shows the other suits and 2+ HP), opener must - similarly with the Sputnik double - double after his partner’s pass if he has 2-3 cards at most in the opponent’s suit.  His partner can pass this for penalty, with weak hands he bids his long suit (and in this way the final contract).

If one bids 4 NT directly after the sequence 1 ♣ -1 -2 ♣ - 2 //♠ - 2 NT – 3 NT – 4 ♣ - 4 (à shows slam interest with ), this denies a fit and is a game proposal.

 

 

The slam invitations sent this way (via 3 NT therefore) in the or ♠ suit can by way of exception be passed with an absolute minimum; 4 NT is now 5 Ace Blackwood (41/30).
