PREEMPTIVE BIDS - CONVENTION TO IMPROVE COMPETITIVENESS img_site/spades.gifimg_site/hearts.gifimg_site/diamonds.gifimg_site/clubs.gif

When you have some System information about the hand of your
partner you will surely be more competitive than other partnership
that play in the dark for some situations.
Thus, lets here comment some usual conventions used for advanced players to have more competitiveness in bridge.

******************************************************
** 
Rule of 3 and 2
** In a competitive auction the rule of 3 and 2 determines how many

**
** In same vulnerability only 2 down
**     (nVul game=420 x down 2 = 300) (Vul game=620 x down2=500)
** Opponents Vul x nVul up to 3 down 
**     (Vul game = 620 x nVul down 3 = 500)
** Opponents nVul x Vul only 1
**     (nVul game = 420 x Vul down
1 = 200)

PREEMPTIVE OPEN CONVENTIONS FOR LEVEL 2, 3 and 4

1-
A open in a weak 2img_site/diamonds.gif/2img_site/hearts.gif/2img_site/spades.gif always brings a pressure in opponent
interference
, so it is good to disturb opponent bidding and this initiative
allows also a
constructive bidding for the partnership if Responder
knows the consistency of the suit bid
ded by Opener to make easy to
Responder conclude how many tricks they can make in a normal distribution of the cards.   

a) Suppose partner opens 2
img_site/spades.gif and you have img_site/spades.gifQ7 img_site/hearts.gifA109x img_site/diamonds.gifJ1063 img_site/clubs.gifAK2,
if you have an agreement with your partner to open in first and second
position in weak 2 only having 2 top honors you can now imagine that
your
side bidding 3nt will have a chance more than 67,83% of success
(% remainder cards
in an 8 cards suit for 3-2 division) to make 9 tricks because your side can make 6s+1h+2c and opponent have no chance in make 5 tricks!


b) Suppose partner opens 2
img_site/diamonds.gif and you have img_site/spades.gifA4 img_site/hearts.gif109xxx img_site/diamonds.gifA3 img_site/clubs.gifKQ2, and you have agreement with your partner that 2nt ask for a stopper (A/K/Q) in a lateral suit. Then if after 2nt Opener bids 3img_site/clubs.gif, it is clearly an Clubs ace because you have KQx. Thus now you can count 6 tricks in img_site/diamonds.gif, 3 tricks in img_site/clubs.gif and 1 trick in img_site/spades.gif. So you must bid 3nt with very good chance of success because opponents will make maximum 4 tricks in img_site/hearts.gif if img_site/diamonds.gif has a normal division in 3-2.  

Conclusion, having a correct information about the weak opening suit is  fundamental to Responder's take decision merging his cards with Opener's cards
.  

It is inexplicable how a partnership can have competitiveness when
a player in first or second position opens weak 2 sometimes with:
c) 
img_site/spades.gifA4 img_site/hearts.gifJ109xxx img_site/diamonds.gif63 img_site/clubs.gifK42 with 2img_site/hearts.gif   maybe make 3nt and stay in 2img_site/hearts.gif
d) 
img_site/spades.gifK108654 img_site/hearts.gifJ109x img_site/diamonds.gifimg_site/clubs.gifK4 with 2img_site/spades.gif  maybe make 4img_site/hearts.gif and not 3nt
e) 
img_site/spades.gif54 img_site/hearts.gifimg_site/diamonds.gifA965433 img_site/clubs.gifKQ104 with 2img_site/diamonds.gif maybe make 5img_site/clubs.gif and not 3nt
How his partner can make a decision with such irregular opening?

Rule-0: After a preemptive opening at level2 or 3 the 4img_site/clubs.gif bid by Responder is RKB1430 asking for keycards in the weak suit opening and 4nt is Blackwood asking only for aces.

Rule-1: The weak 2 opening in first and second position must have 2 top
honors (AK/KQ/AQ) in the opening suit and can hase only one additional top honor in another suit.
Thus, in first and second position Opener should not not open with:
a) img_site/spades.gifA42 img_site/hearts.gifxxx img_site/diamonds.gifKJ10963 img_site/clubs.gif4  <= no 2 top honors in img_site/diamonds.gif
b) img_site/spades.gifimg_site/hearts.gifAJ10842 img_site/diamonds.gifK63 img_site/clubs.gif942  <= no 2 top honors in img_site/hearts.gif
c) img_site/spades.gifKQ987x img_site/hearts.gifQ102 img_site/diamonds.gifimg_site/clubs.gifK42 <= maximum 1 lateral honor

Rule-2: the Responder's bid of 2nt apply only to ask for "features"
(a top honor) and
the responses are:
R2.1 - rebid his suit - no additional honor - minimum
R2.2 - other suit - a top honor
(A / K / QJx) - maximum
R2.3 - 3nt with AKQxxx in the opening suit

Rule-3: After weak opening in first and second position the response bid
in a major is one round forcing and asked for support of 3 cards or honor
second. Without any support Opener with maximum can bid his
side top honor en passant if possible or with minimum just rebid his suit.

Rule-4: After a weak open in 2img_site/diamonds.gif/2img_site/hearts.gif/2img_site/spades.gif/3img_site/clubs.gif/3img_site/diamonds.gif/3img_site/hearts.gif/3img_site/spades.gif the response bid in 4img_site/diamonds.gif is reserved to ask for singleton in the Opener's hand and then response 4nt is used to show singleton in the other minor.

Rule-5: after a weak open in
2img_site/diamonds.gif/2img_site/hearts.gif/2img_site/spades.gif/3img_site/clubs.gif/3img_site/diamonds.gif/3img_site/hearts.gif/3img_site/spades.gif the response bid in 4img_site/clubs.gif is RKC1430 and response bid in 4nt is Blackwood asking for aces.
         Opener               Responder
 2weak or 3weak        4
img_site/clubs.gif  <=  RKC1430

       
 Opener               Responder
 2weak or 3weak        4nt
<=  Blackwood for aces
     the response are: 5img_site/clubs.gif = zero 5img_site/diamonds.gif = 1 ace adn 5img_site/hearts.gif = 2 aces

Note: So there are no support for minors at level 4 after weak2 or weak 3 open unless there are interference in the bidding.

Examples where in first or second position a preemptive bid occurs:

Opener hand:

2- Same situation occurs in the preemptive open at level 3.
f) Suppose partner open 3
img_site/diamonds.gif and you have img_site/spades.gif
Axx img_site/hearts.gifJ109x img_site/diamonds.gifK63 img_site/clubs.gifA62,
if you have an agreement with your partner that a weak open in level 3
3
img_site/diamonds.gif/3img_site/hearts.gif/3img_site/spades.gif need 7 cards with A or K at top and 3img_site/clubs.gif with only 6 cards need 2 top honors to be opened, then if you have Axx or a Kxx you can bid 3nt with a great chance of success.

g) Suppose partner opens 3
img_site/spades.gif and you have img_site/spades.gifAx img_site/hearts.gif
QJx img_site/diamonds.gifQJx img_site/clubs.gifAKxxx, if Spades are 2-2 (40%) but if partner has KQ chances raise to more than 90%, maybe 100% if partner has KQJ, the contract of 3nt is better than 4img_site/spades.gif because there are 4 losers in the reds.

Again, how a partnership
may have competitiveness when a player in first or second position opens weak 3 sometimes with:
h) 
img_site/spades.gifx4 img_site/hearts.gifJ109xxxx img_site/diamonds.gif63 img_site/clubs.gifAK
i)
 img_site/spades.gifQ865432 img_site/hearts.gifJ109x img_site/diamonds.gifimg_site/clubs.gifK4
j)
 img_site/spades.gif54 img_site/hearts.gifimg_site/diamonds.gif10986543 img_site/clubs.gifAQ104
How his partner can make decision
s with such irregular opens?
The honors of the hand must be concentrated in the suit bid, even because, if opponents play the hand, and the lead belong not for the opener
, but to his partner, if he leads a King second and astonished see declarer make the ace and Qx is in dummy; or play the ace and see xx in dummy and partner has QJ109876 and declarer make his Kx.
So, the indication for lead is requirement that the suit must have at top an A or K to have effective competitiveness also in defense.

Rule-6: In the weak open at level in 3img_site/diamonds.gif/3img_site/hearts.gif/3img_site/spades.gif in first or second position, requirements are: 7 cards with A or K at top; or 6 cards in the case of 3img_site/clubs.gif with 2 top honors.

3) What we should agree about an open bid in 4img_site/hearts.gif or 4img_site/spades.gif?

First all preempt
ive bids must be in agreement with the "Rule of 3 and 2" to be justified in business terms.
Well, this is not universal, there are differents styles of partnership and all have their own understanding about
, but preemptive take room for opponents organize and in a disciplined way give partner information to make better decisions. so this polemic.

Lets divide here 2 types of preempt
ive bid for major at level 4:

First- weak preemptive weak- it is a 7/8 cards with 6-12 hcp
missing one or two top honors like:
seven cards: KQJxxxx    AKJxxxx  AQ10xxxx  AJ108763
eight cards: A9875432  KJ965432   QJ876432
This open in first and second position can't have 2 aces.
This open
(4img_site/hearts.gif or 4img_site/spades.gif) can't have another 4+ cards suit

Second: preemptive solider - it is a strong 7/8 cards up to 13 hcp
with all 3 top honors (AKQ) like
in a minor open in 3nt gambling.
 (7 cards) AKQ10982  AKQJ432  (8 cards) AKQ87654
This open can't have void or other ace, just one singleton
and
only one additional king.

The preempt solid use 4
img_site/clubs.gif opening to show 7/8 cards in Hearts and
use 4
img_site/diamonds.gif opening to show 7/8 cards in Spades. 
examples:
k) 
img_site/spades.gifAKQ86542 img_site/hearts.gif9x img_site/diamonds.gifimg_site/clubs.gifQ4  => open 4img_site/diamonds.gif in any position
l)  
img_site/spades.gif42 img_site/hearts.gifAKQJ9xx img_site/diamonds.gifimg_site/clubs.gifKQ4  => open 4img_site/clubs.gif in any position

Note1: When the solid suit of 7/8 cards have additional Ace or 2 Kings, the hand must be open at level 1 and in a GF auction Opener in his second bid must jump to level 3 to show solid suit, not strong open in hcp, the hand can have only 15 hcp but solid suit it is supposed to guarantee 7+ tricks:
examples: 
m) 
img_site/spades.gifimg_site/hearts.gifAKQJ9xx img_site/diamonds.gifxx img_site/clubs.gifAQ4 you open 1img_site/hearts.gif and if your partner bids a GF in 2img_site/clubs.gif or 2img_site/diamonds.gif then you bid 3img_site/hearts.gif with the agreement that the suit bid in jump, if only 6 cards must have 4 top honors AKQJxx or if the suit is 7 cards then must have 3 top honors AKQxxxx, of course you need discuss this agreement with your partner.

NAMYATS is the name of this convention that opening in 4img_site/clubs.gif shows a solid suit in img_site/hearts.gif (img_site/spades.gifx img_site/hearts.gifAKQxxxxx img_site/diamonds.gifKx img_site/clubs.gifxx) and the opening in 4img_site/diamonds.gif (img_site/spades.gifAKQxxxx img_site/hearts.gifx img_site/diamonds.gifQJx img_site/clubs.gifxx) shows a solid suit in img_site/spades.gif.
This convention was used by Samuel Stayman and his partner Victor Mitchell in
the years of 60 - Namyats is Stayman inverted.

Today Namyats is used by many advanced partnerships in international competitions, but with specific details by each one, so we put some restrictions to
strengthen the convention.

Rule-7: the opening of 4img_site/hearts.gif or 4img_site/spades.gif doesn't need A or K at top if the suit has 8 cards like QJ987654, but can't have 2 aces and must obey the "Rule of 3 and 2" to be a safety bid.

Rule-8: 
After the open of 4img_site/clubs.gif or 4img_site/diamonds.gif (in any position) the Responder bids transfer 4img_site/clubs.gif => 4img_site/hearts.gif or 4img_site/diamonds.gif => 4img_site/spades.gif to sign-off the auction.
If Responder bids  4
img_site/diamonds.gif (not 4img_site/hearts.gif) after the open of 4img_site/clubs.gif
or Responder bids 4
img_site/hearts.gif (not 4img_site/spades.gif) after the open of 4img_site/diamonds.gif

is searching for singleton and Opener rebid his suit if he is 7222,

Opener with singleton in the other major bid 4nt.

Rule-9: If Responder's first bid is 4nt then this is asking for the only one king that Opener can have and Opener bids:
- 5img_site/clubs.gif <= no king;

- 5img_site/diamonds.gif <= 1 king;
- 5 on his suit <= KQ (king is together Quees of same suit)
Then Responder sign-off the auction in level 5, 6 or 7.

Rule-10:
After Responder asking for singleton the 4nt bid by Responder is still for king and Rule-9 is on.

Defenae against Namyats
When opponents open Namyats against our partnership we can use:
1- the double of
4img_site/clubs.gif/4img_site/diamonds.gif is not for penalty is this suit, but a take out double for the other major, showing be shorter in their major and have support for the other suits.
Opponent      we
    4
img_site/diamonds.gif           double  =>  img_site/spades.gifimg_site/hearts.gifAQJ9 img_site/diamonds.gifK10xx img_site/clubs.gifAQ10x
    4
img_site/clubs.gif           double  =>  img_site/spades.gifQJ10x img_site/hearts.gifimg_site/diamonds.gifK10xx img_site/clubs.gifAQ10

2- If we pass and they stop in their major
now the double is penalty showing we have 3 loser in that major suit but have 4+ sure tricks in others suits without support for the other major (honor second).
