OPENING BIDS

♣ ♥ ♠ ♦

Follow the links in the table below for a fuller definition of each opening bid , their responses & rebids.

Note: Third hand openings can be lighter and a bid suit shorter! - see 3rd-hand-openings - regular openings listed below will otherwise always apply

Note: Hands with 5-5, 6-5, 6-6, 7-5 or 6-7 are provided with a their own bidding sequences. This group of hands are known as 55+
Never open 55+ with either a 2♣ or 2Ma bid
Minimum 7LTC hands must have a strict evaluation - following Harrison Gray. Otherwise open with the appropriate 1 level bid.

There are SIX 5-5 hand possibilities these are opened as follows:

♥ ♠: Open 3♦
♥ ♦: Open 3♣
♥ ♣: Open 2♦ then rebid 3♣
♠ ♦: Open 2♦ then rebid 3♦
♠ ♣: Open 1♠ then rebid 3♣
♦ ♣: Open 1♦ then rebid 3♣
See 5-5hands for details of further bidding

Beta also allows you to show any 5-5 hand in 2nd position when opponents open the bidding with 1 in any suit: See our Defence bidding allowing description of any unbid 2 suits 5-5 or better and <=7LTC with either <=5 LTC or 6-7 LTC.
If opponents open a weak 2 using our adopted RUBINSOHL defence methodology. 5-5 hands can be shown by fisrst transferring to the LOWER ranking suit - then rebidding in the higher ranking suit.

BETA 1-level openings are as follows:

BETA operates as a '5452' minimun holdings for ♠♥♦♣ 1-level openings respectively.
With 5+ cards in any of ♦|♥|♠ open the longer suit - A Major requires 10+ HCP while 1♦ prefers 11+ HCP. Normal rebids are a 2nd 4 card suit or NT's without. With 16+ make jump rebids.
The upper limit of 1Ma openings are our alertable 2Ma or 2♣ openings requiring a strict <=5LTC or <3.5LTC. Note: Our 2Ma! openings have no specific HCP requirement usually 16+HCP unless Major (6)7+cards
With precisely 4-4 in ♥&♠ in Beta we also open 1♥ with 10+ HCP even when holding a 5+ card minor suit.

1NT opening is 12-14HCP (preferred range for Beta) and stringent conditions must be satisfied - see how to choose: 1C&1N.html NEVER open 1♣ when a 1N opening is valid.
Open 1♣ otherwise. This bid is alertable as it can be just 2 cards. 12+HCP is the only requirement. Actually less than 1/10 1♣ openings possess just 2 clubs!
2♣, 2♦ & 2N take preference over all 1-level openings - excepting 5-5 hands as discussed above.

2-level openings are as follows:

2♣: 23+HCP balanced - ONE 5+ card suit is permitted BUT no void or singleton
2♣: <= 3.5 LTC any distribution BUT NEVER with a 5-5+ See 5-5+ for sequences.
2♣: Also with a 5 Major + 4 Card other suit: prefer to open 2Ma with 3.5-5LTC strict.
2♦! Multi 3-way:

19-20 HCP Balanced, a 5 card Major is OK: rebid 2N or rebid *|** if interference
2-suited 5-5 or longer D-S or H-C. See above.
A classic 'weak Major 2'

2Ma!: Requires 5+ cards & another 4 card suit. <=5LTC (strict)
2Ma!: Requires 6+ cards suit and <=5LTC
2NT: 21-22 Balanced. 5 card Major is permitted.

3-level opening bids

3mi!: Attention - these bids are NOT pre-empts, they show 5-5+ hands - see above
3Ma: Classic Major pre-empts
3N: Gambling - long solid minor - little else! as then opponents less likely to have slam!
4Ma: Distributional bids - To play
4mi: minor Pre-empts

3rd Hand Openings

Suit bids in 3rd position lighter, even somewhat pre-emptive openings are tolerated. Partner needs to be aware of this.
1NT opening in 3rd and 4th positions may be shaded to 11 HCP i.e. 11-14HCP range
Weak 1 Spade 3rd position openings are acceptable even with 4 cards to a top honour

Some relaxations are permitted. See 3rd Hand openings.

4th Hand Openings

1NT Opening is relaxed to 11-14 HCP Balanced distribution otherwise as given above
Suit openings of 1 Spade make sense - but exercise caution re-opening the bidding with other suits as opponents may overbid with spades and win the bidding and the hand.
