Overcalling Opponents Opening bid of 1C! or 1C|1D
♣ ♥ ♠ ♦
Raison d'etre
BETA now opens 1♣
more frequently than any other bid showing 12-18 HCP and fairly
balanced hands.
More distributional hands follow other paths. There is
a growing tendency for other Systems to increase the frequency of
opening 1♣ without other opening available OR others will open, dare I say, an old fashioned 1♣ or 1♦ with a definition of 'better minor'.
As a consequence of this it behoves us to examine avenues of taking
advantage of this situation. This document is an initial attempt. On
one hand we aim to make bids to disturb their sequences and consume
their bidding space with moderate values and on the other hand have
bids that can show our strength and distribution when we have it. A
balanced approach. We commend the following specifications,
applicable
to BETA ONLY, now formally adopted. Note precision 1♦ openings are also included in this approach too as well as 'better' minor.
NOTE: Exception is a 1♣!
alerted to be Strong - e.g Precision or other strong Club systems
showing at least 16+HCP. Beta's defence in this case is TRAP.
Beta's motivation for the following 3-pronged approach is based on making best use of all bidding space the opponents have granted us.
A) DOUBLE. Adopts their 1♣ opening bid as our own :- we
can state we are in 1st and I have a BETA 1♣ opening position and with a simple
DOUBLE.
This states "we would have opened 1♣ ourself!! This
adopted 1♣! shows our usual 12-18HCP 1♣ opening bid.
Partner responds with the usual BETA sequences following partner's now
assumed 1♣ opening!
A bis) Opponents open 1♦. Double now operates in a similar way: announces that we would have opened 1♣ showing 12-18.
In either case partner is expected to respond as if 1C 12+ had been opened.
E.g. 1♦(opp)-*-1♠(opp)-* Shows Hearts!
B) 'Ignoring' the opponents 1♣|♦ opening.
Partner simply makes an overcall 1 of ♦|♥|♠
over opponents 1♣ opening showing: 10+ HCP and a 5 card suit ♥|♠|♦
respectively or in case of 1♥ bid possibly 4-4 in Majors. Also
similarly overcalls ♥|♠ over 1♦ showing the bid suit. These are NORMAL
BETA 1-level resposes to a 1♣! opening - these are not O'calls! They show 10+ HCP & a 5+ card suits. BETA 1♦(5+♥'s); 1H(5+S's or
4-4 in ♥-♠); 1♠(5+♦'s). Over 1♦ overcalling 1♥ or 1♠ announces normal 5+ card BETA openings.
There is one difference 1♣-1S BETA shows 10+ denying 5+ card major showing 5+♦'s.
Partner continues as if partner's 'o'call' had
actually OPENED the bidding! BUT all must recognise and
remember that your LHO's has shown opening values - and nothing else as
yet!
C) BETA Attacks! with the best of BETA by making alertable overcalls of 1N or higher over opponents 1♣ or 1♦ short openings.
These bids of 1NT or above are all aimed at either disrupting
opponents bidding, showing specific strong hands or presenting 2-suited hands or pre-emptive bids: all of which
can effectively disrupt the opponents normal bidding - primarily by robbing
them of their bidding space: thereby disrupting their bidding or showing our strength or strong distributional strength.
These BETA 'coded' alertable bids as specified in BETA that are usually
opening bids e.g 2♦, 2Ma or 3mi but now available as o'calls but carrying
the same message. Also bids such as 2♣, 1NT or 2NT which are usually
overcalls and above follow with distributional meanings as given below:-
1NT! Our multi 1NT. There are several meanings but the most
frequent of which is: Showing Both minors at least 5-5. Partner
required to bid 2♣ if his RH opponent passes. Rebids of 3♣ weak or 2♥ strong both
showing 5-5 in the minors
2♣! Both majors 10+ 4-4 or better
2♦! Our versatile multi 2♦ - a 3-way bid: a) Weak Major 2 b) 19-20 Balanced c)
5-5 or better in either Clubs & Hearts OR Diamonds & Spades
2Ma! Not at all weak 2's! Shows <=5 LTC with 5+ Card Major and a
2nd suit of 4 cards. Partner may PASS, Raise OR inquire with 2N.
May also be used to show a quality 6+ card suit and
<=5LTC
2NT! Shows Spades & Clubs at least 5-5 & <=7LTC
3♣: shows both red suits at least 5-5 <=7LTC
3♦: shows both Majors at least 5-5 <=7LTC.
3♥ and all higher suit bids are all pre-emptive openings in BETA usually (6)7+ cards.
