Opening bids etc...


This page gives just an outline to some frequently found sequences in the first 4 bids.

Beta ACOL opening bids are mostly natural:
That's all looking straightforward wouldn't you agree? However the above is simplified, full specification is given only in the full text.
There are a couple of additional rules for choosing an opening of one in suit (when stronger openings are excluded 2, 2, 2 & 2):

Some basic responses to opening bids

Every change to a new suit in the first four bids is to be considered as FORCING - on rare occasions a PASS could be best. However a potentially light 3rd hand opening may be readily PASSed. A new suit at the 3-level will be strictly game forcing. A fourth suit bid or a cue-bid of opponents suit are also forcing. If RHO overcalls partner's opening Beta uses a different approach to ACOL - see detailed texts.

Responders rebids

Some general principals are considered here after 3 suits are bid: - please respect this is only a selection - full detail given in the texts.

3/ opening weak - strong Specific 5+-5+ & LTC 5-8 or even 4LTC

Either both red suits or both majors can be shown respectively. Must be in the range, conservedly, of 5-8LTC & a strict minimum of 5-5.  It caters for rarer 6-5 6-6 even 6-7!
Simple fits cn be shown directly. 3-level  bids are NOT invitational
With intervention raises become, to play or are pre-emptive in nature.
3NT Forcing, (If intervention PASS & *** replace 1st & 2nd steps responses  NEXT & NEXT+1 are 3rd & 4th stepsasks about the shortage - four   steps are : 4  Club shortag, 4 'Other' Shortage 4 Club Void & at least 6-5 & 4. 'Other void

2 opening - Forcing. 3 types of hand  & 3 types of Response: . 

We include this detail here as many players have misunderstandings or little knowledge of a 2D Multi opening

Types of hand:

  1. Weak major 2 - with a 6 or poor 7 card suit- shown by PASS if partner responds 2, 2, 3 or 3
  2. 5-5 or better: either Clubs & Hearts OR Diamonds and Spades - following sequences as in 3 & 3 openings.
  3. 19-20 Balanced hand - may contain a 5 card suit - shown with 2N or 3N (over 2N response only)
Types of responses:
  1. Strong: 2NT: shows either: 12-15HCP with support to at least  the 3-level in both Majors (requires at least xx) OR  (15)+ HCP
  2. Weak responses 2S! Showing either hearts 4 card Hearts or 3 cards hearts headed with a top honour: AKQ  OR simply 2H! Denying Hearts - requests partner to PASS or transfer or show other types of 2 openings
  3. Pre-emptive responses: 3NT: 5-5 or better in both minors OR 3 minor showing a 7 card suit headed by a top honour AKQ
Handling intervention:
As used consistently thoughout the system if partners 2D opening is overcalled PASS except with the strong response then ***
If intervention occurs after partners response then * shows the Strong 2NT hand. Also 3
will have usual meaning . 3 can be 6 card if partner denied Heart support  or 3 showing 7 card Hearts

That's a taster! Now get to the real detail!
