Definition of a Protection bid
This is easy!
The latter can occur at any bidding level!
- 3 preceeding PASS on the 1st round of bidding
- 2 passes since the last bid made by an opponent
If you PASS its the end of bidding and play must then commence.
What are your options?
Accepts the contract so far bid
You believe the opponents cannot make their final contract a bid
in the opponents agreed suit and partner has passed this bid or
the bidding has not been hitherto competed
Optional penalty double As above but partner has not bid since
the last opponent bid in a previously competitive auction.is a penalty
double subject to partner passing.
doubled your contract but you believe it can be made
In certain sequences this maybe used
as a conventional and alertable bid - usually only at bidding levels 1
or 2 demanding partner to bid (again)
Lead Directing Double When doubling a 3NT game contract
where you are NOT on lead (for us the first suit named by dummy)
Any opponent bid above 3N which
is not their agreed suit in an uncontested auction to show a control -
possibly lead directing
Doubling a conventional
artificial bid above 4N is lead directing
Showing your hand Doubling any
opponent bid usually only at level 1 - showing that this was your
intended bid - possibly a conventional bid
You wish to keep the bidding open but are without a suitable suit bid -
also be aware your partner can convert this double to a penalty double
Protective 2 suit bid In tune
with Beta principals a protective suit bid shows 2 suits - this is
safer as it doubles the chances of finding the best place to compete.
The protective bids are the main subject of this page.
Let's look into the last lines - the main subject of this page
There are two different cases when partner has only passed: X =
any suit (the case where the opponents open 1 NT is
(i) 1X(LHO)-P-P-? &
(ii) 1X(RHO)-P-2X(LHO)-P-P(RHO)-? (iii)
In all these situations your primary assumption must be the same - values are probably distributed 20-20.
The solution beta employs is similar in case (iii) are
similar but necessary different as 4 suits are candidates. In
cases of a suit opening 3 suits remain and the approach taken is one
where the protective bidder eliminates one suit (least promising) and 2
specific suits are nominated for partner to choose between. The
philosophy with 4 suits available is to to first specify a good major
if available otherwise to select the better minor - clubs if both good
be suitable. The emphasis on the Majors is made since any suit battle
would be won there and the NT opener would prefer a Major opening if a
suitable on is available.
The essence of any protective bid is that you are bidding with the full expected combined strength available
You cannot guess to which side may have the edge in point count but also who has the better fit? Both come into this equation.
In the 2nd case the opponents have a fit and fair % of their honour
strength is likely to be in that suit. This implies that your strength
lie in the other 3 suits - increasing the probability that at least a
good fit can be found in 1 suit.
An intervention is a good idea but be very cautious if Vulnerable v Not
vulnerable. If unfavourable more distribution is advantageous. Say a
Also if they have agreed a suit then preferably you would like to have
0 or 1 or 4 cards in their suit! as this would suggest less losers in
their suit if you buy the contract
The question now arises of how to act.
Beta works the following way.
A. Opponents open 1 in a suit:
If you hold 2 suits bid the lower ranking cyclically else make a Protective *
If you show 2 suits: Partner is asked to PASS or raise the bid suit or give preference to the second suit.
If you double Partner is asked to indicate his preference knowing that
the odds favour your partner to have at least minimum support in the
suit you choose.
There is another outcome when partner has length in the opponents suit
- oartner may simply choose to PASS - converting your Protective Double
into a Penalty Double.
B. LHO opened 1NT
If you have 2 good suits bid the lower ranking minor but if holding a 5+ Major it should be preferred.
Else If your hand is balanced and has 10+ HCP prefer a protective
double - this asks partner to PASS for penalties (10+ HCP or select best suit, 5 card preferably.
Alternatively a PASS can be considered to convert the protective double
into a penalty double.
Note: In the 2nd position defence to a weak NT 2 suits are required to
disturb a 1NT opening.and double requires at least 13HCP. With a good 6
card suits Rubinsohl can beused as an offensive tool. This approach to
2nd position increases the probability of a 5+ card suit with your
