1♦ Opening bid & Responses
♣ ♥ ♠ ♦
5+ card Diamond suit denies any 5+ card Major suit - [as then the opening would be either 3♣ (both red suits) or 2♦ (rebid 3♦ shows ♦'s &♠'s)]
(10)11+ HCP & 7 1/2 LTC maximum.
Alternative openings that always take precedence:
2NT 21-22 Balanced - ♦ 's may be 4 or 5 cards in a balanced hand
2♣ 23+ Balanced OR 5+ ♦'s & <= 3 1/2 LTC
2♦ 19-20 Balanced OR 5+-5+ in ♦ & ♠
3♣¦♦ 5+-5+ redsuits or Majors.
A 1♦ opening requires a 5+ Card suit and it has to be the longest suit held. (Just One Exception Clubs may also be 5 cards)
Note: With a 6+ card Club suit always open 1♣ unless 12-14 & specifically 2236 then open 1NT!
Partner's Responses 1♦ - ?It is important to note that there is a close synergy between 1♣ & 1♦ sequences in Beta.
In both cases we give priority to showing a 4+ card Major regardless of any other suit or even NT's
Therefore the sequences 1♣-1♦(4+hearts) & 1♦-1♥(4+
Hearts) and 1♦-1♠ (4+ Spades) also categorically denying 4+ Hearts and even if possessing support for
Diamonds or even possessing longer Clubs!
The similarlity does not end here, if you hold both major
4+ cards you must show the Hearts first regardless of their
respective quality or lengths. Beta can handle this largely as
the concept of reverse is not in play.
The similarity does not end here:
- Opener must show the fit (4 card) immediately if possessed, also jumping with (15)16+
responder holds no Major 4+ bid 1N (5)-(9) or 3♦ with 7-10DP and 4+
Diamonds; 2♦ with 4+ Diamonds and 10+HCP; also 2♣ with 4+ cards &
10+. Partner may PASS without a Major and 0-4(5)
- 1♦-1♥-1♠ Opener not holding even a 3 card fit for Hearts but holding 4 Spades must respond 1♠ as partner may hold both majors!
further important rebid with total similarity is opener's rebid of
1NT 12-16HCP & a balanced hand which denies a fit in partners suit
with Crowhurst sequences & 2NT with an appropriate balanced
with 9+ HCP must bid 2♣ and opener MUST now show 3 card support
for partner's previously indicated Major if he has it with a 2bid 12-14
or 3bid with 15-16. Opener if unable to show even 3 card support for
partner's Major must now show a 4 card major, or rebid 2♦'s with nothing more to show or 3♦'s with 6+ cards 15-16HCP. or show Major
cards at the 3-level with 15-16 otherwise as done at the 2-level. and denying Majors 2N With 15HCP & 3♣ with 16HCP.
Responder with <9 must bid as follows:
Make a transfer to his major with 5 cards or rebid his Major with 6+ cards.
- If responder has 5+ Spades as well as Hearts, he MUST now show them
- Responder failing the above may now: PASS
The synergy with 1♣ sequences is shown throughout the above.
One special rebid by Opener is 3♣ It announces 5+-5+ or better in the minors - this following any response by partner or any opponent intervention!
- PASS: 0-4(5) HCP
- 1Ma: 4+ Cards 5+ HCP - with both bid 1♥ always
10+ 4+ card suit. MAY NOT HIDE
a 4+ card Major
- 2NT: Balanced. Only without intervention. Shows 16+ HCP (or 15+ only with minimum positive support for diamonds): BARON
- 2♦: With 10+ HCP & (H3) 4+ card support or Hxx. This is an Inverted minor response denies an unbid major, valid over any intervention (but not over a T-O double: use redouble) bid 2♦ and
ignore a 4 card major if you have one!
Bid 2N over any intervention promises a sound raise to at least the
3-level. Any direct raise to the 3 or higher level is pre-emptive.
- 3¦4♦: With 4+ card support & <10 HCP and preferably and distributional values - pre-emptive nature
RHO doubles for T-O, A redouble shows 8+ HCP denies a diamond fit or a
4+ card Major. Any major held must be shown directly over the opponents
- If RHO overcalls in a suit, a negative double denies a
diamond fit, but shows at least 3 cards in
any unbid suit. Strength depends on the level: 1L: (7)8+; 2L: (9)10+;
3L: (11)12+. Importantly any new suit bid at any level bid denies
the foregoing HCP and is pre-emptive in nature. The only
exception is the sequence: 1♦-1♥-1♠ which is natural and not to be
considered as pre-emptive.
- A direct 1NT 5-9 HCP Balanced denies a 3♦ inverted minor call.
opp)-* Shows Spades, 1♦-(1♠ opp)-* Shows 4+ Hearts - similarity
treatment follows as in 1♣ as described above.
- A 2NT bid following any overcall shows a good raise to at least 3♦. 'Trustcott'; but denies an unbid Major
bids: 3NT, 4Ma & 5♦ To play, These direct game level bids are usually based on suit
length and distribution and are NOT showing slam interest per se,. 3N requires adequate guards
- 4♣¦3♥¦3♠ Natural weak break-outs: 7+ card suits & distributional (No splinters, or SWISS are played over a minor opening).
- Major Jump bids without intervention e.g. 1♦-2♥ 16+ and as usual in Beta shows game values and are automatically a Trump request. With intervention are natural limit bids showing length.
See: Handling 5-5 Hands. 3N is the only forcing continuation by responder.
Opener's Rebids 1♦ - 1Ma
4+ card Spade suit - denies a 4+ card heart support (but with 3 card support Prefer a 1N 12-16)
4+ card Natural. 9+ HCP. Denies any Major interest
12-16 Balanced. 2♣ Crowhurst inquiry available - Beta standard See above 'similarities with a 1♣ opening'.
17-18 Balanced. Invitational. Opener denies a 4 card fit
responder can show a 5¦6+ card major suit - as over a 1NT rebid by
transfer (5) rebid (6+)
4♣ or 3'Ma (Splinters) Shows 4+ card support and a shortage in Clubs or the other Major. Note in Beta Splinters are never used directly over opening bids.
Limit bids without opp intervention, pre-emptive with opp intervention
2NT(trustcott) Sound raise to at least the 3-level following opp intervention.
Jump in a new suit rebid Beta Std: (E.g.: 2 other Ma') This jump rebid by opener is valid in all sequences. It
promises: (15)16+ HCP, A 2-3
card short suit with ideally 2 top honours, in a single suited
Shows a 6+ card suit. 10-14
6+ card suit
Opener's rebid after 1♦- 1NT -? [Responder has neither singleton or void]
Shows 6 Diamonds <15HCP
Natural, balanced limit bids
15+HCP, quality 6+ card suit single suited hand
Beta bid: (15)16+ Shows a Short suit (1)2-3 cards
with top controls
shows a void but a
singleton Ace is acceptable.
Responder's Rebids 1♦-Y(1Ma or 2♣) - New suit(Z): (Technically Forcing)
Forcing. At 2-level shows additional values ; normally forcing to agreement; at 3-level strictly game forcing.
- 4th suit with jump
Genuine values in the bid suit which needs to be 3+ cards with a double
stop. Game forcing, denies support for partner's suits & suggests NT game
- Y Rebid
6+ card suit <10HCP. A stop bid
3 card support - unless the only practical
rebid - WEAK
support - Forward going bid. 10+ HCP
Denies support for both opener's
suits. Strength consistent with
To play -always
Opting to play in Z - possibly only 3 card support
Responder's rebids 1♦
The stronger 2♦ response is forcing, 3|4♦ are pre-emptive Inverted minor
Responder's bids after intervention 1♦-any(OPP)-? 1N: Shows modest values 5-9HCP and may be passed.
A 6 card Diamond suit can be rebid
- a balanced hand
- a guard in OPP Major intervention
- denies Diamond support
- Suggests the other 2 suits - i.e. unbid Majors and Clubs.
Double: Negative double suggests unbid major shows 8+ at 1-level 10+ at 2-level - interest in unbid suits
2N: solid raise to at least 3♦
3♦: Pre-emptive (usually requires some distribution.
2Ma: 5 card suit moderate values use Double with positive values always.
NOTE: Previously PASSed hand e.g. P-P-1♦-any-?
As above but:
2N: 11-12 HCP (previously passed hand only e.g. P-P|1♣-1♦-P|1Ma-2N)
1N: Similarly with 9-10HCP
Suggests guards in opponents naturally bid suit[s] or unbid suits if any.
