The 1 ♦ opening

(Literature: Glenn Groetheim / Alan Sontag, The Viking Precision Club, Norwegen 2002)

The 1 opening shows 11-15 HP.  Into this opening are placed all hands for which we have no other opening in the system.  As a rule the bid shows 2+ , however occasionally it can contain a singleton.  If there is a singleton , then there will not be a 5 card major nor a good 5 ♣ with a good 4 card major.  Because we open 1 NT when vulnerable and generally in 4th seat with 14-16 HCP, this is often conceivable only with a 4-4-1-4 distribution, and in first and second seat with 11 HP a pass is at least not excluded (especially if the singleton is a minor honour).

 

We open, with the 4-4-1-4 variant too, any hand if we have at least 12 HP.  If we have only 11 HP, we always open in first and second seat if we have at least 2 defensive tricks and have an easy rebid (whatever partner bids).  It should be remembered that, when non-vulnerable, we open 1 NT in first to third seat with hands containing 10-12 HP, hands therefore which are just on the border (or slightly under it) of a normal opening.  The rebid of 1 NT after a 1 opening tends to show a balanced hand, vulnerable as well as in fourth seat with 11-13 HP, non-vulnerable on the other hand with 13-15 HP; one can only have another strength in such a sequence if there are good reasons for not opening 1 NT.

 

 

As a rule the player who opens 1 has a hand of the following structure:

5+ , unbalanced hand

A balanced hand, which could not open 1 NT because of the strength

A hand with both minors.  At the same time it should be noted:  With 6 and 5 ♣ or 5 and 6 ♣, always open 1 ;with 4 and 5 ♣ one always opens 1 ,with 4 and 6 ♣ when one does not have sufficient points for 2 ♣, otherwise with (13/14)15 HP, one opens 2 ♣.

 

 

To estimate whether a hand should be opened needs much experience.  There are no firm rules, only guidelines.  Therefore one must open with 11 HP if one has 3 quick tricks and a long suit, especially if the high cards are in this suit.  However one should have 14 points including distribution (count 1 point for a 6 card suit, two points for a 7 card suit).  Nevertheless, one should pass if one has a maximum of two quick defensive tricks.  In general:  Because in our system the opening is limited to 15 HP, one may open more aggressively than in natural systems; especially in third seat!

 


 

 

 

Examples of minimal openings: 

 

1                   with                ♠ KJx xxx AKxx ♣ xxx

 

(1 NT, if we need 10-12 HP for it)

 

1                   with                ♠ Qxx KJxx xxx ♣ AKx

 

1                   with                ♠ Kxxx A109 KQ10x ♣ xx

 

(green 1 NT, because we need 10-12 HP for it)

 

1                   with                ♠ Qxxx AKJ7 xx ♣ Qxx

 

(green 1 NT, because we need 10-12 HP for it)

 

In third seat one could also open 1 red! 

 

1 NT (green)   with                ♠ Qxx KJxx Jxx ♣ Kxx

 

 

In third seat one should open aggressively, on the one hand to disturb the opponents, on the other hand to show partner where one would like the lead.  However, one must note also the Spade Rule in fourth seat.  Add up the high card points and add it to the number of spades in the hand:  If the total is less than 15, we do not bid (for we dont want to open for the opponent). 

 

 

 

The responses:

 

 

Opener

Responder

Meaning of the bid

1

Pass:

Possible with 0-6(7) HP

 

1 :

         Variant 1:  6+ HP, 4+

         Variant 2:  Hands (without regard to the distribution) that wants to reach game (as a rule from 13 HP); therefore this variant is only possible if one has not passed already.  Note further that after an opponents double, the bid is natural.

 

1♠:

6+ HP, 4+ ♠, with a shortage in from 5 HP possible; the bid is forcing for one round, but not to game.

 

1 NT:

6-10(11) HP, no 4 card major, balanced distribution or weak with 6+ ♣ (too weak for Two over One, therefore 6-7 HP).

 


 

 

After all these bids (also after 1 if one has already passed and therefore cannot have a hand which will force to game), the bidding is perfectly natural.  Note that as a rule opener shows without a jump or alternatively without a reverse strengths of 11-14(15) HP, with a jump or reverse on the other hand a good (13)14/15 HP (with points and lengths in both suits).

 

Also if responder has not yet passed and now bids 1 1 , opener bids first of all in natural manner.  Opener cannot now support partner with 3 because it is not certain whether the bid is natural or not.  He can only show 3 directly then if an opponent intervenes: then double shows 3 (Support Double).

 

A strength of our system is that the bids are limited; to take advantage of this also means taking a risk occasionally with weak hands.  As an idea:  One bids for example with   ♠ J852 754 985 ♣ 654 1 ♠ and passes partners response - the success can be surprising.

 

Opener

Response

Meaning that bid

1

2 ♣:

10-12 HP, 4+ ♣ (our special relay system follows, cf. later); with long ♣ one can have also 8-10 HP; the bid is forcing for one round.

 

2 :

11-12 HP, can be passed, however tends to be forcing for one round, 5+ , inverted minors (cf. below); if the opponent intervenes with 1 or 1 ♠, one can also have stronger hands to use inverted minors, as the relay of 1 forcing to game is no longer available.

 

2 :

(3)4-9 HP, 5 ♠, 4-5

 

2 ♠:

6 ♠, (4)5-8 HP, with or without a fit in , to pass as a rule

 

2 NT:

         Variant 1:  Natural, (10)11-12(13) HP, balanced distribution, no 4 card major

         Variant 2: Passed hand/the bid not vulnerable shows both minors (5-4 or 4-5 therefore did not open 2 NT) with 9-10 HP (Reason:  We have not opened 1 NT with 10-12 HP).

 

3 ♣:

Invitational, 10-11(12) HP, good 6+ ♣, missing at most one of the top four honours

 

3 :

Pre-emptive, 5+

 

3 :

Invitational, 10-11(12) HP, good 6+ , missing at most one of the top four honours

 

3 ♠:

Invitational, 10-11(12) HP, good 6+ ♠, missing at most one of the top four honours

 

3 NT:

To play, balanced as a rule, minimum (no slam interest)

 

4 ♣:

5 Ace Blackwood with as trumps (as a rule one usually goes through 1 ), answers 41/30

 

4/5 :

Pre-emptive

 

4 /♠:

To play, at least 7 cards in the bid suit, no slam interest (otherwise use the game forcing 1 ).

 

4 NT:

Ask about the 4 aces, answers 41/30

 


 

 

 

The sequence 1 - 2 shows a maximum of 9 HP and at least 5-4 in ♠/, the sequence 1 - 2 ♠ is natural, showing a 6 card suit (without regard to suit quality, and can therefore be 10xxxxx) and a weak hand (5-8 HP).  Therefore, if one first bids 1 ♠ and rebids the suit, one is always showing 6 ♠, with however 9-10 HP.

 

Exception:  If opener now rebids 1 NT after 1 - 1 or respectively 1 - 1 ♠, the rebid of the suit - therefore 2 or respectively 2 ♠- is still weak, as a rule now with a 5 card or (with ♠ a very bad) 6 card suit.  With 10 HP and 6 cards in or respectively ♠ as well as a fine suit, one would have shown this already after the opening by a jump to the 3 level.

2 ♣:

 

Natural, 4+ ♣, 9+ cards in the minors, as a rule 5+ and 4+ ♣ (4 /6 ♣ only possible with a bad ♣ suit or less than 15 HP); 2 is now a forcing relay to game; if responder has a weak hand and a hand like 3-4-4-2, he must pre-emptively raise to 3 with it.

The continuations are now mainly natural.  With the Relay Trigger (here 2 ♣ after 1 - 1 - 1 ♠), responder announces after openings in first and second seat that he wants to reach at least game.  Now the relay sequences start.

 

After openings in first and second seat, responder can therefore start a relay sequence with 2 ♣ after 1 - - 1 ♠.  Responder can always get out of the relay sequences by selecting another bid.  This bid is always natural, whereby a game force exists because of the 2 ♣ relay.  If one has changed into a natural sequence and a fit is known, cue bids follow.  However, back to the relay sequences:  If one knows the exact distribution, the relay is an ace ask (the following relay is for kings, after that follows the queen ask).  Each time only the 4 cards are queried, this according to the Crash scheme (Colour-Rank-And-SHape):

 

If the first ask is at the 2, 3 or 4 level:

 

Crash step 1:  1 or 4 aces

Crash step 2:  0 or 3 aces

Crash step 3:  2 aces of the same colour (red or black)

Crash step 4:  2 aces of the same rank, therefore in the majors or in the minors


 

 

Crash step 5:  2 aces of unequal colour or unequal rank, therefore ♠ and or and ♣

 

By analogy it goes to the next relay for kings and later queens.  The bid of game in the trump suit or respectively a suit in which partner has shown 4+ cards is never a relay (then the next higher bid is the relay).

 

If the second or third ask is made with 5 ♣ or higher:

 

Crash step 1:  0 or 3 kings (queens)

Crash step 2:  1 or 4 kings (queens)

Crash step 3:  2 kings (queens) of the same colour (red or black)

Crash step 4:  2 kings (queens) of the same rank, therefore in the majors or in the minors

Crash step 5:  2 kings (queens) of unequal colour or unequal rank, therefore ♠ and or and ♣

 

If the first ask is at 4 NT:

 

Crash step 1:  1 or 4 aces

Crash step 2:  3 or 0 aces

Crash step 3:  2 aces

 

If the first ask is at 5 ♣ or higher:

 

Crash step 1:  0 or 3 aces

Crash step 2:  1 or 4 aces

Crash step 3:  2 aces

 

If the response has shown an honour, one can clarify in which suit this top card is.  Instead of bidding the first relay suit, one simply bids the next higher suit (or No Trumps) which cannot be trumps (therefore has not shown 4+ cards).  The replies are as follows:

 

With one shown honour:

 

Step 1:  Honour in the longest suit (if two equally long suits:  In the lower ranking suit)

Step 2:  Honour in the second longest suit

Step 3:  Honour in the second shortest suit

Step 4:  Honour in the shortest suit

 

With two shown honours:

 

Step 1:  Honours in both longer suits

Step 2:  Honours in both shorter suits

 

With three shown honours: 

 

Step 1:  The honour is missing in the shortest suit

Step 2:  The honour is missing in the second shortest suit

Step 3:  The honour is missing in the second longest suit

Step 4:  The honour is missing in the longest suit


 

 

 

Here too, with two equally long suits:  Show the lower suit first.

 

 

If the opponent doubles a relay by the enquirer, responder bids on as if there had been no double if he has the ace or at least king doubleton in the doubled suit. Otherwise he waits for his partners redouble and then bids his responses.  If on the other hand the opponent bids a suit, pass shows the first step (partners double is then again the relay), double the second step and so on. If the opponent doubles a response to the relay, the enquirers pass replaces his relay (responder redoubles for step one, bids the first step for step two etc.), redouble is to play. If the opponent bids after a response within the relay sequences, enquirers pass replaces the relay, double on the other hand is for penalty. Responders first step is then double.

 

 

Responder can always break out of the relay sequences if he selects another bid.  Therewith the final contract is determined.

In contrast to the sequence 1 - 1 - 1 ♠ - 2 ♣ - 2 in the bidding sequence shown below, one can no longer distinguish between minimum and rather good openings.  However the strength zone comes to light from the fact that there was not a different bid (in particular 1 No Trump was not opened).

If opener now rebids 1 NT after the relay of 1 , one already knows a balanced hand without a 4 card major.  Again 2 ♣ is a relay after openings in first and second seat and forces to game.  After openings in third or fourth seat, we use the 2 ♣ bid as Roudi.

To repeat/clarify:  Since after 1 - 1 - 1 NT the relay of 2 ♣ forces to game, we can not play Roudi.  Therefore 2 NT is natural and invites 3 NT.  Nevertheless with inviting hands and 5 to find a fit, after 1 - 1 - 1 NT one can bid 2 ♠with 3+ ♠, which with us is only forcing for one round.

 

 

 

The bids after openings in third and fourth seat:

 

 

If responder has already passed, the sequence 1 - 1 is as you know natural and therefore we use the Roudi convention if openers second bid is 1 NT.

 

Responder who has bid a major gets to learn openers strength on the one hand, on the other hand whether or not he has 3 cards support.  For Roudi one needs 10(11) HP, usually one has 5+ cards in his major (not forcing!).  With 5 one would hardly have 11 HP (otherwise one would have already opened 1 ).

3 ♣/:

 

14-15 HP, 3 , values in ♣ or respectively

!

 

 

With the responses of 3 ♣ or respectively 3 , one shows moreover a weakness in the other minor (therefore for example 3 small cards).

 

 

How does one remember the responses to Roudi?

 

2 and 2 NT deny 3 cards in partners suit, whereby 2 shows a minimum and 2 NT shows a maximum hand.  The bid of partners suit shows a fit and a minimum, the bid of the other major shows a fit and maximum.


 

 

 

With this convention therefore one can find out among other things how strong opener is.  Therefore it makes no sense in the following bidding for the bid of 2 NT to be invitational for 3 NT:

 

 

 

Pass

1 /♠

 

1 NT

2 NT:

2 NT is therefore in all these cases a transfer to .

 

 

If one wants to invite 3 NT, one uses Roudi; if partner shows a maximum, one bids 3 NT, otherwise 2 NT and so shows the invitation.

 

 

 

 

1 - 1 - 2 ♣:

 

 

However, we turn to the other responses by opener.  If he bids 2 ♣ after the relay of 1 , one knows of at least 9 cards in the minors.  Now the relay of 2 forces to game.

In the variants, with which one knows only 9 or 10 cards, the Sidestep relay has a nuance:  The first step shows a minimum (11-12 HP), the relays after that ask further.

As just seen, we play Roudi in such situations. The player who has a major suit and bids Roudi learns on the one hand the strength of opener, on the other hand whether he has 3 cards in the major.  For Roudi, one needs 10-12 HP, usually one has 5+ cards in his major (not forcing!).

With the 3 ♣ or respectively 3 answers, one shows moreover a weakness in the other minor (therefore for example 3 small cards).

 

How does one remember the responses to Roudi? 2 and 2 NT deny 3 cards in partners suit, whereby 2 shows a minimum and 2 NT shows a maximum hand.  The bid of partners suit shows a fit (here ♠) and a minimum, the bid of the other major shows a fit (here ) and a maximum.

 

The jump by responder in his suit to the 3 level shows at least 6 cards and is inviting.

Reverse

 

If partner has responded with 1 ♠ after a 1 opening, the bidding behaves naturally after a (only exceptionally allowed) reverse (15 HP and points in both named suits and a 3 card fit in ♠ or an extreme two suiter).  All bids force to game, the only exception is 2 NT.  This bid asks partner to bid 3 ♣.  Partner can pass the subsequent 3 ♣ bid or however bid a suit, which is also not forcing.

Inverted minors:

 

On the one hand not to land in 3 NT without cover in all suits, on the other hand to be able to bid good minor suit slams also after intervention, we use the Inverted minor convention.


 

 

 

1

2 :

11-12 HP, (4)5+ (Inverted minor), no 4 card major; Attention:  Applies also after opponents suit intervention at the 1 level (then there is no upper limit as to strength), not however after a take out double (then 2 shows 6-10 points, ditto 2 NT however longer , 3 11-12 points), an intervention of 1 NT or an intervention of 2 ♣.

 

 

If the opponent intervenes with 1 NT, inverted minor is also cancelled (double shows 8+ HP, 2 ♣ shows 4 (4 ♠ possible), 2 shows 4 ♠ (without 4 ), 3 is a natural bid).  If the opponent intervenes at the 1 level (1 or 1 ♠) and we use Inverted minor, this has no upper limit (the opponent has taken away the relay of 1 ).

 

After suit interventions at the 1 level and a response of an inverted minor, the bidding goes along exactly like without intervention (for example the opponent intervenes 1 ♠, a bid of ♠ would announce values in ♠ and does not ask about a stopper).

 

The pre-emptive bid at the 3 level can also be made with less than 6 HP if one has the feeling that the opponents have the majority of the points.

 

With the continuations, it is a matter of primarily bidding the suits in which one has a stopper for 3 NT.  However, opener can also show slam interest with 2 NT (a maximum and good values, just under a 1 ♣ opening, often with extreme distribution).  If responder declines, stoppers are shown again for 3 NT.

 

1

2

2 :

stopper for No Trumps

2 ♠:

♠ stopper for No Trumps, no stopper

2 NT:

Slam try, 15 HP, often two suiter with 4+ , good values in the hand; the invitation is accepted with 3

3 ♣:

♣ stopper for No Trumps, no stopper in and ♠

3 :

Weak, pre-emptive

3 /♠:

Splinter, slam interest

3 NT:

Game proposal, stoppers everywhere

 

All these stopper bids by responder after intervention at the 1 level can also be early cue bids (= advanced cue bids), which one shows later by bidding beyond 3 NT and shows slam interest.

 

If opener shows a stopper for No Trumps, responder bids in the same way cheaply from below.  He likewise shows a stopper for No Trumps. If he skips a suit, he denies a stopper there.  If a suit is skipped and later bid, this now shows a half stopper (for example Qx or Jxx) and asks partner for a half stopper; if he has this, he bids 3 NT.

 

If opener shows slam interest with 2 NT, responder can accept this when he now bids 3 of the opening suit - therefore 3 .  Then


 

 

 

cue bids follow.  If on the other hand responder has no slam interest, he shows this by bidding another suit again cheaply as a stopper for 3 NT.

 

Because of the Inverted minor convention, all direct jump raises of the opened minor are played as pre-emptive.

 

1

3 :

Maximum 10 HP, 5+ , pre-emptive; Attention:  This also applies after opposing suit overcall at the 1 level, not however after a take out double (then 2 shows 6-10 points, 3 or respectively 2 NT show 11-12 points)

 

4 :

Pre-emptive, 7+

 

5 :

Pre-emptive, 8+

 

 

 

 

Suit bids at the 2 level/2 NT

 

 

Suit bids at the 2 level are part natural, part conventional.

 

 

1

2 ♣:

11-12 HP, 4+ ♣ (with good 6+ ♣ from 8 HP is possible)

After an opening in third or fourth suit, the bid shows 7-11 HP and at least 5 (usually 6+) ♣; provided that partner bids further, the same Two over One auction is used.

 

 

1

2 :

(3)4-9 HP, 5 ♠, 4-5

 

2 ♠:

5-8 HP, 6 ♠

 

 

1

2 NT:

11-12 HP, balanced hand, no 4 card major

 

 

 

 

Continuations after Two over One (1 ♦ - 2 ♣)

 

We play openers continuations after Two over One as follows:

 

1.)     All bids are natural but minimum, as a rule 11-13(14) HP

 

2.)     With 14-15 HP, game in most cases is guaranteed because responder has 11+ HP as a rule.  With 14-15 HP, one simply bids the next suit ( 2 ) which is a relay.


 

 

 

1

2 ♣

2 :

Relay, 14-15 HP

2 :

4 , 5+ , 11-13 HP

2 ♠:

4 ♠, 5+ , 11-13 HP

2 NT:

11-13 HP, balanced distribution

3 ♣:

11-13 HP, 4+ ♣ (exceptionally with 3 card suit with an honour permissible)

3 :

(4)5+ , 11-13 HP

3 :

6+ , 5 , 11-13 HP

3 ♠:

6+ , 5 ♠, 11-13 HP

3 NT:

14-15 HP, balanced distribution, vulnerable probably singleton ♣ (otherwise one would have opened 1 NT)

4 ♣:

5+ , 5+ ♣, (12)13-15 HP, good suits, with at least second round control in and ♠, 5 Ace Blackwood

 

 

If responder rebids his suit after openers forcing relay of 2 , he had an idea and bid Two over One with too weak a hand (8-10 HP, 6+ ♣).  This bid can now be passed.

 

 

From that arises also that 1 - 1 NT can only include 6 ♣ if one is weak (6-7/8 HP).

 

 

After the forcing relay by opener, the bidding develops as follows:

 

 

All bids except the relay of the next suit are natural.  They show as a rule a pithy hand therefore unbalanced hand (exceptions: No Trump bids).

 

 

If however responder has nothing special to show and would rather hear what partner has, he simply bids the next suit, which is a relay and inquires further.  If he bids No Trumps, he has the suit in which opener made the relay.  For example:

 

1

2 ♣

 

2

2 :

Relay, suggests a balanced hand that partner should show what he has

 

2 ♠:

Natural

 

2 NT:

Has the relay suit, in this example therefore

 

3 ♣:

8-10 HP, 6+ ♣, not forcing

 

3 //♠:

Natural

 

Also after the second relay, one shows this relay suit with a No Trump bid. To illustrate with the following example:

 

1

2 ♣

2 (Relay)

2 (Relay)

2 NT:

I have at least 4 with my 4+


 

 

 

Jump to a new suit at the 2 level or to 2 NT

 

 

1

2 :

Natural, (3)4-9 HP, 5 ♠, 4-5

 

After that, further bidding develops naturally.

 

From that follows:

New suit:

Natural

 

 

If one jumps to 2 NT after the 1 opening, this shows a balanced hand without a 4 card major and 11-12 HP. However if one has already passed and is not vulnerable, the bid shows 9-10 HP and 5-4 or 4-5 in the minors.

2 NT

3 ♣:

Natural, can be passed

3 :

3 :

10 HP, inviting with good 6+ and only one top honour missing

 

3 ♠:

10 HP, inviting with good 6+ ♠ and only one top honour missing

 

 

Now opener immediately knows a lot and can estimate which would be the best contract.  He continues bidding naturally.

 

 

 

Further jumps

 

 

1

3 NT:

13-15 HP, balanced hand, absolutely flat hand (probably 3-3-4-3 or 3-3-3-4, otherwise go via 1 )

 

4 /♠:

Natural, to play , (7)8+ cards

 

 

With minors, the ace ask via 4 NT is bad because one is usually too high with the responses.  Therefore we play the following convention:

 

 

1

4 ♣:

Ace ask, 5 Ace Blackwood with as trumps

 

 

The responses are like those after the ace ask with 4 NT (cf. see later); the first step simply corresponds to 5 ♣ etc.

 

 

1

4 NT:

4 Ace Blackwood (usually with own solid suit)

 

 

However with this ace ask, only the four original aces are of interest; 5 ♣ shows 0 aces, 5 one ace, 5 two aces, 5 ♠ three and 5 NT four aces.

 

 

To be sure, these direct ace asks are only rarely needed, because with our relay system after 1 - 1 we can learn much more.  With 1 - 4 NT, one has a solid side suit and for the level of the contract is only concerned with the number of aces in the other suits.  It is similar to 1 - 4 ♣ where only aces and the quality of the suit are of interest.
