SWISS 4 or 4

and some other structural sequences...

     

SWISS bids are direct 4 or 4 jumps over an opening of 1|1 even with any opponent intervention.  
Ex .:  1
-2(opp)-4 OR 4
This promises solid support in partner suit - at least 4 cards & values for at least the 4-level.
These SWISS bids also promise balanced hands - that is : no singleton or void!
BARON 2N jump response also shows a balanced hand but deny 4 card support for partner.

These SWISS bids all show a Balanced hands NO V|S & (15)16+ HCP with good 4+ card support. for partner's major.
If a SWISS bid is made following an opponent's intervention then there can be a shortage in the opponents bid or implied suit.
Note: SWISS bids are the antithesis of SPLINTERS! Splinters are not used in this system in direct response to Opening bids --- However Splinters are used in Beta over responder suit. E.g. 1-1-4♣|...or  1-1-4...

The difference between SWISS responses of 4 & 4 is as follows::
4 promises EXCEPTIONAL trump support usually at least 6+ HCP in the trump suit.
This would reassure an opener who is concerned about the honour strength he holds in his suit - who might well otherwise not attempt a slam.

Those who adore the  splinter and abhor our  non-use in direct response  to a Major opening should understand our policy that responder has many ways to show a unbalanced hand in BETA, e.g using  DGR or a new suit without jump,   also structuraly Beta needs partner to show his own suit in the first response (also seen as forcing in BETA on opener).

In Beta a strong balanced hand with 16+HCP without 4 card support for partner's opening suit may bid 2N baron.

Subsequent to suit agreement, eg SWISS bids, or delayed support(limit bids), In either case opener may continue to game or in Beta any new suit following direct or implied suit agreement is automatically a cue-bid (showing a control), inviting slam interest, & TURBO NOT NLACKWOOD follows!
Note: Cue-bidding can show Singletons and voids as well as Aces & useful Kings!

BETA fundamentally believes that responder shows his suit ASAP - this is important for many reasons - E.g. it helps determine how well the hands fit. It also can bring to light a useful double fit. Often critical too in deciding 'for or against' a SLAM venture!

Note: BETA does NOT use direct splinters over Major openings however splinters can be used following a change of suit by responder!

Important generalBETA  understandings:-

    An important theme in BETA is a direct3-level jump response in a NEW suit is WEAK at least 6+ cardsto at least an Honour.
    Also valid throughout BETA ... a rebid of your suit by opener or responder ALWAYS promises 6 cards. However when responder makes such a rebid it shows weakness <= (HCP!. When opener rebids he is NOT showing weakness but also denying a 4 card 2nd suit. Showing a 2nd suit in BETA is considered forcing for 1 round.
     Now a jump rebid in a new suit in BETA shows a shortage with control usually and 16+ HCP (Note: 2 Exceptions: 1S and 1D openings followed by 3C with or without jump promise a 5-5 and at least <=7 LTC)
     we also play 4th suit as game forcing & invoking Cue-bidding.

In Beta we use 2N following an intervention in a 'sort of TRUSTCOTT style' promissing at least 4 card support and a solid  raise to at least the 3-level and is valid over minor as well as Major openings! - unlike SWISS  this style of showing support operates for minors as well as Major Beta openings! Again responder also promises a Balanced hand - no singleton or void! BETA doea

Example  1(partner)-1(opp)-2NT-  Shows a solid raise of partner's Diamond suit, showing a minimum 4 card support and forcing to at least the 3-level.
