2 Major opening bid
All 4 of the following requirements for any 2 Major opening must be present:
a) 15+ HCP usually,
but acid test is a strict 4-5 LTC, only usual exception for <15HCP are more distributional holdings: 6+-4
or 5440 or good 5431
b) 5+-5+. distributions - except Spades - Clubs see 2D and 3C/D openings.
c) With <4LTC open 2
d) Distribution: 5+ card major & a 4+ card suit OR a 6+ Card Major
5431 preferred to 5422 - with a minimum 5LTC & 5422 distribution
consider opening 1 of the 5 card suit and rebidding the 4
f) A 5 card Major should be headed by at least a top honour: A or K -. If not: open 1Ma.
g) A 6+ card Major and no 2nd suit
requires a minimum of 2 top honours.
These 2Ma bids are structural in the system. They
reduce the top end of a major opening to about 15(16)HCP -
giving a usual maximum range of 10-(16). (For a balanced hand or flat hand
with only a 4-5 card major the upper limit is (18} HCP; (18)19-22 HCP hands
are either opened 2D or 2NT and puppet resolves the Major)
Note 1: These openings are non-forcing. Alert as 'strong non-forcing'
Note 2: The first rebid by opener (except when partner makes a raise) distinquishes 2-suited 5+-4+ from 6+ hands.
Note 3: In the sequence 2H-2S, opener must show a 4 card spade else rebid as if partner had responded 2NT
Note 4: 2S & 2NT responses are both Forcing & Inquiries to
explore opener's distribution - promising hand to be playable in at
least 3 of partner's major
Opener's rebids following: 2 or 2NT Forcing responses:
- PASS - the opening is NOT forcing. However very limited
vakues can support a 3-level contract and 2N¦2S should always be
- 2S. (Over 2H only). Shows 4+ Spades & invitational values. This allows for the otherwise difficult
case of 5 Card Heart suit and a 4 card Spade suit. (A sequence like 2H-2N-3S forces bidding to game level).
2NT forcing relay,
with invitational values the only continuation (along with 2S
response above) by which to initiate exploration of distribution
& controls for a probable Game or possible Slam.
- Limit Major raises, with a fit for partner's
major - to 3¦4 level. Assuming
partner has observed the minimum requirements for his 2Ma opening even
limited values and some support may be sufficient for game - Note: if
you raise to 3Ma, partner with a 4LTC will now bid game. Also if RHO
has overcalled (rare) direct raises are still limit in nature - never
3-level bid, without jump is pre-emptive, shows a good 6 or 7+ card suit Forcing (Strictly implies no fit
- 0-2 cards in partner's major & usually denies holding any other 4 card suit).
- 3NT! NOT to play, RARE, shows both minors 5-5 or better, minimum this is weak & denies major fit
- 4mi, RARE, shows a long minor usually 8+ card & denies major fit
- 3S over 2H is w/ea/k showing a 7+ card spade suit and denies a heart fit.
- Limit Raises over 2 with a 4+ card fit
- The sequence 2H-2S-2N! shows 6 and 3 cards . This opens up the possibility of finding a 5-3 spade OR 6-2 Heartt fit: 2H-2S-2N!-3¦4S or 4N RKCB looking for a Spade slam
- 4-level minor Splinter in a bid over only a 2 response shows 4 card fit: I.e. 2H-2S-4mi with minor singleton or void
- Rebids his major with 6+ cards and NO 2nd suit.
- A new 4 card side suit (, , ) FORCING showing a 5-4 distributio (2S-2N-3C will be 4+ clubs). Sequence remains Foricing to 3 of opener's Major.
- Jump bid over 2N response shows shortage also denies a 2nd suit but shows SLAM interest - cue-bidding and Turbo follow.
Opener's 2nd rebid clarifies distribution as follows:
- Agrees a trump suit at any appropriate level
- 3NT expresses no fit - offered as a possible contract - Opener
may now rebid PASS to play or rebid 4Ma with 6+ cards or show a
'partial' in a 3rd 'suit 3-4 cards Forcing. Responder may now introduce
his suit at any level to play!
- A new suit by responder is FORCING showing s lam interes and is a cue-bid - implies at least one suit bid by opener is agreed. TURBO
follows. Note responder cannot introduce a new suit at this juncture -
it will also be interpreted as a control showing bid
Further bidding by either partner:
- Show a 6-4 or 5-5 distribution by rebidding in either of his suits OR
- A '3rd suit' by opener shows a 3¦4 card 3rd suit.
Showing a 5431 or 5440 distribution. This shows slam interest. However if partner makes a cue-bid, known as 4th suit is a cue bid Responder can sign-off in either of opener's suits or cue-bid OR
Turbo (4NT or higher bid) - all bids above 4NT are cue-bids until a return to the agreed suit
- 4NT or higher bids are always TURBO after 2Ma openings - never ERKCB and may be invoked by EITHER partner
- Beyond 4NT cue bids may not show singletons. Only Aces, 'useful Voids' and 'useful Kings' are permitted
- Return to agreed suit is a sign-off
Ex1: 2H-2N-3C-4C-4D - a cue bid
- Cue-bids below 4NT
- TURBO 4NT (if trumps agreed OR implied) Showing an EVEN number of Key Cards
- Showing controls (showing ODD number of Key Cards) when bypassing 4NT
- 5NT can be invoked to get further useful information - e.g. Q Trumps, Other useful honours not yet shown: No: agreed suit,Yes: Lowest available other than agreed suit.
- Agreed suit - no more to say!
Ex2: 2H-2S-4D (agrees spades and a cue-bid
Ex3: 2H-2N-3mi-3¦4H to play OR 4¦5 mi to play OR any new suit a cue-bid indicates undeclared support for one of opener's
suits. TURBO follows...
