There is a war out there!!

 One who logically dares, interferes and pre-empts wins
FuB Mini NT, 3 Way 1C openings, combined with 2 and 3 level Hexagon (multi-six) opening, are aggressive and pre-emptive conventions that are difficult to defend against. They are elegantly simple and logical, giving any player a competitive edge even against experts.
So you are the dealer! Almost half the time, you pass as you don’t have a conventional opening hand. What a waste of opportunity! Opponent’s get into bidding and we start struggling for part scores or we give them a free or easy ride to bid for game and investigate slam.
Wouldn’t it be good if you could open most of the time, describe your shape and points to your partner, cut opponent’s communication, be disruptive, and reach your optimum contract while your opponent’s are bewildered or reduced to guessing?
FuB Mini NT, 3 Way 1C and Hexagon openings which are core of this bidding system will achieve this through a very logical and structured way.
 
Objectives of the three conventions:
·         Get in early and open almost twice as many times as you open normally
·         Fiercely compete and often win the biding in the part score games
·         Determine level and purpose of the bidding auction early (part score, game, slam, sacrifice)
·         Pass information to partner in a structured way
·         Make it appear complex to opponents but simple for yourself through a well understood structure
·         Cut opponent’s communication and be disruptive so that opponents miss their optimum or correct contract
·         Find marginal games and slams in highly distributional hands
·         When partner opens Mini NT, have tools available to find our own game, penalize opponents if they come in biding and it is our game, try to avoid being penalized or minimize the damage when it is clearly opponent’s game or slam.
·         Still be able to adopt basic gadgets and conventions as partnership requires (5 card major, Stayman, Transfer, Jacoby, Slam bidding gadgets such as Blackwood variations/splinter/cue biding, Bergen, Lebensohl, DONT/Cappelletti)
 
What types of hands are covered?
The three conventions (FuB Mini NT, 3 Way 1C opening and Hexagon), between them and in a pre-emptive but logical structure cover the following hand types:
·         Hands with 8-10hcp without 6 card major or two suited 5-5
·         Hands with 11-14hcp balanced
·         Hands with 15-17hcp balanced
·         Hands with 18-19hcp balanced
·         Hands with 20-21hcp balanced
·         Hands with 22-23hcp balanced
·         Hands with 24-25hcp balanced
·         Hands with 26+hcp balanced
·         Single suited game force
·         2 suited game force
·         3 suited game force
·         Weak single suited
·         Weak 2 suited
·         Strong single suited (but not game force)
·         Gambling 3NT hands
·         Weak 7 card suit in majors
·         Weak 8+ card suit in minors

3 Way 1C Opening (11-17hcp)

·         11-14hcp balanced or semi balanced hand
·         15-17hcp balanced or semi balanced hand
·         Opening hand with 5+ clubs unbalanced

Use of Lebensohl when partner’s strong 1NT opening is interfered
This is a great convention. After a 2 level bid by opponents, responder’s 2NT bid simply ask opener to bid 3C. With Lebensohl, you simply need to understand a few principals:
·         Any immediate 2 level bid is weak, natural and sign off
·         Any immediate 3 level bid is strong, natural and game force
·         Any cue bid of opponents suit is Stayman
·         Any immediate bid (Cue bid or NT bid) shows no stopper in opponents suit (fast arrival)
·         Any delayed Cue bid or NT bid (after 2NT-3C Lebensohl sequence) shows stopper in opponent’s suit (slow arrival)
When partner’s strong 1NT is interfered with a bid, following bids by us are Lebensohl convention:
·          X                                       Penalty
·          2 level bid                          Natural, weak to play
·          3 level bid                          Natural, forcing to game
·          Cue Bid opponents             Stayman, no stopper in opponents suit
·          3NT                                    Game force, no stopper in opponents suit
·          2NT                                    Lebensohl – Forcing opener to bid 3C
In above sequences where Cue Bid or 3NT indicating no stopper, it is up to opener to change to appropriate suit or bid NT or leave it at 3NT with stoppers.
Purpose of the 2NT Lebensohl is to describe other situations not covered above such as:
·          To sign off at 3 level (when it wasn’t possible at 2 level) with a weak suit
·          To bid Stayman and tell partner that we also have stopper at opponents suit
·          To bid 3NT game force and tell partner we also have stopper for opponents suit
·          To show a natural suit with invitational values
Responder’s rebid after 3C by opener to describe above situations are as follows:
·          Any bid below 3 level of opponents suit = sign off (if C is our suit, responder will simply pass)
·          Any bid at 3 level above opponents suit = natural & invitational
·          Cue bid opponents = Stayman with stopper
·          3NT = Game force with stopper
Notice difference between Cue Bid and 3NT bids when is done immediately after interference or after 2NT Lebensohl (slow bid). An immediate bid shows no stopper and a slow bid shows stopper.
 
FuB* - Mini NT (8-10hcp)
 
We open 1NT with 8-10hcp (no 6 card suit or no 5-5 two suited) at first, 2nd and third seat with any vulnerability. Hand can be unbalanced and even have singleton or void.
 
This is going to cause a lot of problems for opposition as traditional conventions such as DONT or Cappelletti are not very effective against it.
 
This convention helps us to find our game or correct contract while allowing a mechanism to escape opponents doubling us for penalty and occasionally turn the table and convert their double to a makeable 1NTxx contract.
 
Response sequences to 1NT openings
If there is no interference:
·         Pass to play
·         2C is relay to 2D
·         2D/2H/2S to play
·         2NT 18-19 balanced
·         3C relay to 3D; I have a massive hand, GF, don’t stop until game is bid
·         3D Strong opening hand with D 
·         3H Strong opening hand with H
·         3S Strong opening hand with S
·         3NT to play (usually 17+ without 4 card major, or long suit with source of tricks)
·         4C Game in C or S (same color), pick one
·         4D Game in D or H (same color), pick one
·         4H Game in H or S, pick a major partner
·         4S Game in S or D, pick one (S stronger suit)
·         5C Game in minor, pick a minor
·         5H good chance of slam in majors, with a bit of help pick one or sign off at 5H or 5S
·         6C slam in minors, pick one
·         6H slam in majors, pick on
·         After 2C-2D relay, responder bids are:
o        Pass is an option with very weak hand and 7+ D
o        3C opening hand in C
o        2H opening hand in H (or 4-4-4-1 with good quality 4 card H) 
o        2S opening hand in S (or 4-4-4-1 with good quality 4 card S) 
o        2NT 15-17 balanced (occasionally with 4-4-4-1 and no quality major)
o        3D opening hand in D
o        4H Game in C or H, pick one
o        4S Game in S or D, pick one (D stronger suit)
·         After 3C-3D relay, responder bids are:
o        3H/3S/4C/4D single suit GF
o        5C slam in C and S (same color)
o        5D slam in D and H (same color)
o        5H slam in H and C
o        5S slam in S and D
 
If there is interference:
If opponents bid we can pass or overcall with good suit
 
If opponents X, we can use any of our 3 level bids as above if applicable
 
If opponents X our 1NT opening for penalty in sequences such as:
1NT – X or
1NT – P – P – X
 we use SWINE defense as follows
·         With 2 touching suits and at least 4-4 (or best 4-3 if our distribution is 4-3-3-3) we bid:
o        2C = C/D
o        2D = D/H
o        2H = H/S
·         With a long suit we redouble, partner will bid 2C
o        We pass with C being our long suit
o        We correct to our long suit
·         We pass, requiring partner to redouble after which:
o        We pass if we are happy to play 1NT redouble contract
o        2C shows C and a Major. Partner pass with Club support or bid 2H asking for the major
o        2D shows D and S. Partner selects
o        We bid 2H/2S this shows 5+H/S with good values. This shows a better hand than redouble and then bidding 2H/2S
 
Exception to 1NT opening with 8-10 point range and good 6-4 shape in majors
With a good 6-4 in majors, opposite a suitable hand, there is potential for game. In such cases we may choose not to open 1NT. If partner opens 1C our 2H or 2S response will show this shape hand.
If opponents open or partner doesn’t open, we can bid 2H/2S, showing exactly such hands.

Principal of Hexagon
Hexagon is an aggressive pre-emptive 2 and 3 level opening convention that is difficult to defend against. It is elegantly simple, logical and easy to remember, giving any player a competitive edge even against experts.
Hexagon can be used in conjunction with any conventional 1 level opening. However it is most effective if used with FuB Mini NT and 3 Way 1C Openings. It applies to the following hand categories which collectively cover about 17% of all hands:
When we open 2 of a suit (say 2C), we have one of the 6 following possibilities (hence name Hexagon or Multi-six), 2 weak and 4 strong:
·         Strong C suit with about 8 ½ tricks
·         Weak hand in the suit above (in this case D)
·         Strong 3 suited hand with shortage in the suit above (in this case D).
·         Weak 2 suited hand in the 2 suit above (in this case H and S)
·         Game Force 2 suited hand in the 2 suit above (in this case H and S)
·         Strong balanced hand in this case 18-19hcp
Responder has to bid and initially bids the next suit up. Responder with a very strong hand, in particular where there is strong game possibility with the 2 weak options above can also bid 2NT. Next bid by the opener will reveal his shape and strength.
Responses after 2C/2D/2H/2S/2NT Hexagon openings
 
Each suit opening covers 6 possible hands. Partner generally bids the next suit up (unless has strong hand that can enquire by biding 2NT). If opener repeats the suit, it is natural & strong.
If passes, it was weak in the next suit up. If raises the next suit up, it is 4-4-4-1 with shortage in that suit. If bids any of the other 2 suits at minimum level, it is 5-5 weak. If bids any of the other 2 suits at a higher level than available, it is 5-5 game force and if bids NT, it is strong balanced hand. Such sequence is very logical and makes it easy to remember.
Response sequences
With 2C/2D/2H/2S openings, when there is no interference, responder normally bids next suit up the line until opener reveals his holding. If responder has interest in game or can compete with any of the opener weak options, responder enquires by bidding 2NT. If responder doesn’t bid suit up the line or 2NT and instead bids another suit, he is interested in game in that particular suit with self sufficient trump and looks for small support to go for game.
 
In response to 2NT opening, responder bids first suit (up the line from C) with 3+ card holding, or bids 3S enquiry, or bids 3NT to play.

5.3H with game force D/H (responder can decide further course of action; bid game in 4H/5D/3NT, bid 4D as RKC for D or 4NT RKC for H)
6.3NT for 24-25hcp responder can use Gerber or bid 6NT/7NT
Opener re bid if there is interference:
1.Bid S
2.Pass
3.4C with singleton/void in C
4.Pass
5.Bid D or double for penalty
6.Bid 2NT, pass or double for penalty
 
Response sequences to 2NT opening
Opener rebid after 2NT à 3x bid
·         With 26-27 hcp, bid 3NT
·         With weak C/H or D/S
o       Pass if x is your suit
o       Bid your next suit up if x is not your suit
·         With GF C/H or D/S
o       Raise x if x is your suit (if major to game)
o       Bid your major to game (responder to pass or correct to your minor)
Opener rebid after 2NT à 3S enquiry
o       With 26-27hcp bid 3NT (grand slam is on, highly unlikely combination)
o       With weak C/H or D/S bid your minor suit at 4 level
o       With GF C/H or D/S hand bid your major at 4 level
 
Responder bid after 2C/2D/2H opening and interference by right hand side.
Responder can pass, bid 2NT or X
·         2NT: Usually stronger with interest in game in any of the weak options. Opener should usually bid his suit but has option to X for penalty if opponents interfere again and bid one of his suits
·         X: normally indicates partner can compete is any of the weak options. Opener can still pass for penalty if opposition have bid his suit
 
Exception to 2D/2H Hexagon opening with 8-10 point range and good 6-4 shape in majors
With a good 6-4 in majors, opposite a suitable hand, there is potential for game. In such cases we may choose not to open 2D/2H. If partner opens 1C our 2H or 2S response will show this shape hand.
If opponents open or partner doesn’t open, we can bid 2H/2S, showing exactly such hands.
 
SWINE
 
If opponents X our 1NT opening for penalty in sequences such as:
1NT – X or
1NT – P – P – X
 we use SWINE defense as follows
·         With 2 touching suits and at least 4-4 (or best 4-3 if our distribution is 4-3-3-3) we bid:
o        2C = C/D
o        2D = D/H
o        2H = H/S
·         With a long suit we redouble, partner will bid 2C
o        We pass with C being our long suit
o        We correct to our long suit
·         We pass, requiring partner to redouble after which:
o        We pass if we are happy to play 1NT redouble contract
o        2C shows C and a Major. Partner pass with Club support or bid 2H asking for the major
o        2D shows D and S. Partner selects
o        We bid 2H/2S this shows 5+H/S with good values. This shows a better hand than redouble and then bidding 2H/2S
 
Signals
Reverse count: low-high = even, high-low = odd
Low encourage for attitude
Odd/even for discard (odd = like that suit), Even = McKenny (suit preference)
 
Bergen Raises
When your partner opens major and you have fit at 3 level or 4+ level, Bergen raise is a method of communicating your point range (in a modular form) and number of trump support (3 or 4+).
Dummy points when you have support
Sum off:
·       High card points
·       Long suit points (1 for 5 card suit, 2 for a 6 card suit etc)
·       Short suit points
§                               1 point for each doubleton
§                               For singleton add 2 points with 3 trumps and 3 points for 4+ trumps hand
§                               For void value is the same as dummy’s # of trumps
Bergen Responses
Partner opens major (say 1H), you will respond as follows:
·       2H              with 7-10 dummy points and 3 H support (business as usual)
·       3C              with 7-10 dummy points and 4+ H support
·       3D              with 10-12 dummy points and 4+ H support
·       2S              with 10-12 dummy points and 3 H support (if partner opens 1S, 3H response)
·       3H              with 2-7 dummy points and 4+ H support
·       3NT            with 13-15 hcp, 3 H and 4-3-3-3 shape (non forcing)
·       2NT            with 13+ dummy points and 4+ H support or 16+ & 3 H support
Notice overlap points. This is to apply judgment for good and bad points and to upgrade or downgrade.
Reasons to upgrade: Aces, honors in long suits, quality suits with 4+ cards and 3+ honors
Reasons to Downgrade: Queens and Jacks specially in suits with no honor, singleton K,Q,J, honor in short suits
Opener points revaluation after Bergen Raise (Bergen Points)
Sum off:
·       Initial high card and length points (1 point for 5 card, 2 points for 6 card etc)
·       Extra points if trump suit is 6+ cards (1 for 6 card, 2 for 7 card etc)
·       One point for any side suit with 4+ cards
·       Short suit points
§                               4 points for void
§                               2 points for singleton
§                               No point for 1 doubleton, but 1 point (in total) if more than 1 doubleton
Total points and final contract
Total opener’s Bergen points and responder points and aim for where contract belongs:
§       If definitely 26 total points, bid game
§       If may have 26 points, make a game try
§       If you may have 33 total points, investigate slam
Subsequent responses
After 1H – 2NT response (support & 13+ dummy points, 4+ trump), opener will use Jacoby responses as follows:
With singleton or void in C/D/S will bid 3C/3D/3S
With no singleton or void, opener describes his strength so partner can decide if look for slam or not.
4H       with 12-14 Bergen points
3NT     with 15-16 Bergen points
3H       with 17+ Bergen points
Game/Slam tries after 3C & 3D responses.
 After:
1H/1S – 3C we can invite by bidding 3D or 3H
 
After:
1H/1S – 3D
·         bid of a suit at 3 or 4 level below game is cue bidding, showing 1st or 2nd level control, interest in slam.
·         4H/4S to play
·         3H/3S shows minimum balanced. Responder can pass or take to game. 
 
Bergen Raises after interference or partner overcall
After RHO Doubles: Yes, we ignore X and use Bergen Raises as usual
After RHO Overcalls
If overcall is at 1 level such as; 1H-1S or 1H/1S/1NT: Yes we use Bergen Raises
If overcall is at 2 level: No, we bid naturally including use of Cue bids
Partner Overcalls: No, if possible we use Drury or Cue bid (refer to competitive bidding)
 
Game try bidding sequences
 
After   1M-2M-3x is short suit game try

It
shows a short suit and asks responder to make a judgment for game or sign off at 3H/3S (if maximum and values in other suits).

1M-2M-2NT by opener shows 15-17 typically a 5-3-3-2 hand, responses
·         3C Minimum, bad trump (5-7 pts)
·         3D Minimum, good trump
·         3H Max, bad trump (7-9 points)
·         3S Max, good trump
·         3NT AKQ of trump
·        

1H-1NT-2NT shows 18-19 hcp forcing to 3C after that opener bids:
·         3H shows 6 card H and asks responder to bid 4H with 2 card support
·         3NT without 6 card
 
1S-1NT-2NT shows 18-19 hcp forcing to 3C (unless bids 3H as below) after that opener bids:
·         3S shows 6 card S and asks responder to bid 4S with 2 card support
·         3NT without 6 card
·         3H by opener showing 4 hearts (with 5 hearts sequence would be 1S-1NT-3H)
·         If responder bids 3H rather than 3C, is showing 6 cards in H for an alternative game choice
o        Opener can bid game in H or still bid 3S showing 6 cards in S
 
 
1S-2H-3H is forcing with slam interest, inviting cue bids
 
1S-2H-2S-3S and 1H/1S-2x-2H/2S is forcing
 
Defence to Gambling 3NT opening
·       4C = both majors with preference for H or neutral
·       4D = both majors with preference for S
Lead ace against 3NT (if you have one), watch for dummy, partner to give signal if possible and look for continuation to defeat the contract.
 
Defence to artificial strong 1C opening such as Precision
After opponents 1C artificial bid we can immediately overcall with a single suited or double suited hands as follows:
·       Pass                       = Weak or balanced 13+
·       1H/1S                     Natural, good suit 9+ points
·       2C/2D                     Natural, good suit 9+ points
·       X                            = Color – 2 suited
·       1 ¨                         = Rank – 2 suited
·       1NT                        = Odd - 2 suited
·       3NT                        = Gambling 3NT (Pre-empt in a minor)
·       Other jump overcall = pre-emptive
If partner bids X, 1D or 1NT indicating a 2 suited hand, we will bid the lowest rank suit that we have 3+ of that suit. Partner can pass if there is a match or bid his suit at lowest possible level. We can then pass or correct to the other suit.
Lionel Defence to strong 1NT opening
Lionel convention can be used for overcalls over weak or strong 1 NT. It is very useful for competing when we have 4-4 fit and points are distributed.
Following bids are natural and can be made with less than opening hands.
·2H/2S/3C/3D         = Natural, 5+ and good suit
·2NT                      = Minors, 5-5
 
With 11+ points and 4+-4+ in major and another suit
·X                          = S-another
·2C                        = C-H
·2D                        = D-H
 
A X followed by 2NT bid shows 18-20 points balanced hand (in particular over weak NT)
3H/3S bid after weak 1NT is natural, showing very strong hand requiring a bit of help from partner for game.  
Responses after X
·Pass               = 10+ hcp. Any double after that is for penalty.
·2S                  Weak raise
·3S                  Pre emptive
·2NT                S support, invitational
·3C/3D/3H        S support, invitational with singleton/void in bid suit
·2C                  Pass or correct to 2nd suit
·2D                  Natural non forcing, Doubler can bid H with H and less than 2D
·2H                  Natural non forcing
 
Responses after 2C/2D
·Pass                     to play
·2H                        Weak raise
·3H                        Pre emptive
·2NT                      H support, invitational
·3C/3D       Pre emptive
·2S                        to play
·2D/3C                   to play
 
FuN* - Defence to Mini or weak NT
 
Mini NT is a 1NT opening with typical range of 8-11 hcp. Traditional conventions such as DONT or Cappelletti are not very effective against Mini NT. Following is a convention, based on FuB Mini NT opening, allowing us to overcall and describes our hand accurately to our partner.
 
Bidding sequences over opponent’s Mini or Weak NT openings
·         X shows a balanced or semi balanced hand with 11-14hcp
·         2C is relay to 2D
·         2D/2H/2S shows less than opening hand with good 5 or 6+ cards
·         2NT 18-19 balanced
·         3C relay to 3D; I have a massive hand, GF, don’t stop until game or slam is bid
·         3D Strong opening hand with D 
·         3H Strong opening hand with H
·         3S Strong opening hand with S
·         3NT to play (usually 17+ without 4 card major, or long suit with source of tricks)
·         4C Game in C or S (same color), pick one
·         4D Game in D or H (same color), pick one
·         4H Game in H or S, pick a major partner
·         4S Game in S or D, pick one (S stronger suit)
·         5C Game in minor, pick a minor
·         5H good chance of slam in majors, with a bit of help pick one or sign off at 5H or 5S
·         6C slam in minors, pick one
·         6H slam in majors, pick on
·         After 2C-2D relay, responder bids are:
o        Pass is an option with very weak hand and 7+ D
o        3C opening hand in C
o        2H opening hand in H (or 4-4-4-1 with good quality 4 card H) 
o        2S opening hand in S (or 4-4-4-1 with good quality 4 card S)
o        2NT 15-17 balanced
o        3D opening hand in D
o        4H Game in C or H, pick one
o        4S Game in S or D, pick one (D stronger suit)
·         After 3C-3D relay, responder bids are:
o        3H/3S/4C/4D single suit GF
o        5C slam in C and S (same color)
o        5D slam in D and H (same color)
o        5H slam in H and C
o        5S slam in S and D
 
Response to partner’s X (11-14 hcp):
We typically treat this as partner has opened a weak NT and use any convention by partnership agreement.
 
If opponent’s redouble for playing 1NT XX, any bid by us shows at least 4 card suit. Any change of suit to be passed.
 
* FuN stands for Fend your NT. No other 4 letter words should be used as substitute.
 
2 Way Checkback
Main purpose of Checkback is to find fit in major and to distinguish between responder (with invitational hand) bidding a major with four cards or with five cards (remember that rebidding a suit promises six, rebidding with five is considered poor bridge).
Checkback is a bid by responder, similar to Stayman to determine if opener is holding a 4-card major or 3-cards in responder’s bid suit. It is used in a biding sequence such as:
1 Minor - 1 Major – 1NT;
·         2C = Checkback (invitational)
·         2D = Checkback (game force)

Opener replies:
2D/2NT = No 3 card in the bid major or 4 in the unbid major
2H = 4 hearts (or 3 if responder suit is hearts)
2S = 4 spades (or 3 if responder suit is spade)
 
Reverse Drury
If partner overcalls a major or opens at 3rd or 4th seat, he may be weak. When we have an invitational hand and support for partner, to find out if partner was weak or has a genuine opening strength hand we use Drury by bidding 2C.Opener/Overcaller responses are as follows:
Opener replies:
2D = Opening hand
2 of suit = Less than opening hand
Any other suit = Opening hand and 2nd suit
 
For Slam – 1430 RKCB asking for key cards
1430 RKCB asks for key cards
·5C = 1 or 4 key cards
·5D= 0 or 3 key cards
·5H = 2 key cards without Q of trump
·5S = 2 key cards and Q of trump.
After 5C or 5D, next suit up asks for Q of trump. Responses are:
·Return to trump suit = No Q of trump
·Any other suit, yes I have Q of trump and this particular King.
In response to 5NT, we either show kings or bid grand slam with a source of tricks.
 
Minorwood - 1430 RKCB by bidding 4C or 4D
This is used for exploring slam in minors in situation when a minor suit fit is established (explicit or implicit) such as:
1C à 3C, 1H à 2C à 4C, 2C à 2D à 3C, 2H à 2NT à 3D
1D à 3D, 2H à 2NT à 4D
2NT opening (minors) à partner having good minor support and slam interest
A bid of 4C or 4D in these situations is a 1430 RKCB with agreement on C or D as trump. Responses are step up.
For example after 2NT à 4D or 1H à 2D à 4D, responses will be (for diamond trump):
4H à 1 or 4 key cards
4S à 0 or 3 key cards
4NT à 2 key cards but no Queen of diamond
5C à 2 key cards and Queen of diamonds
After above responses, partner can stop by bidding 5D, (4S or 4NT) (over 4H, 4S) to ask for Q of trump or bid 5H asking for kings. If we responded 4H or 4S with 3 or 4 key cards and partner stops (assuming 0 or 1), we should take it to slam.
Similarly after 1C à 2C or 1S à 2C, a bid of 4C is also RKCB (not CRO Gerber) with following responses:
4D à 1 or 4 key cards
4H à 0 or 3 key cards
4S à 2 key cards but no Queen of clubs
4NT à 2 key cards and Queen of clubs
After above responses, partner can stop by bidding 5C, (4H, SS) (over 4D, 4H) asking for Q of trump or bid 5D asking for kings. If we responded 4D or 4H with 3 or 4 key cards and partner stops (assuming 0 or 1), we should take it to slam.
 
Other slam asking tools – Jump to 5NT or raise to 5 level
Jump to 5NT after trump is established (grand slam interest, asking for number of top 3 trumps honors responses 6C, 6D, 6H, 6S for 0, 1, 2 or 3 top 3 trump honors)à
Raise to 5 of the agreed major (small slam interest, asking partner to bid 6 with 2 of the top 3 trump honors, otherwise pass)
DOPI – If interference over ace asking bids
 
Response after partner’s 1NT opening is interfered - Lebensohl
This is a great convention. After a 2 level bid by opponents, responder’s 2NT bid simply ask opener to bid 3C. With Lebensohl, you simply need to understand a few principals:
·       Any immediate 2 level bid is weak, natural and sign off
·       Any immediate 3 level bid is strong, natural and game force
·       Any cue bid of opponents suit is Stayman
·       Any immediate bid (Cue bid or NT bid) shows no stopper in opponents suit (fast arrival)
·       Any delayed Cue bid or NT bid (after 2NT-3C Lebensohl sequence) shows stopper in opponent’s suit (slow arrival)
When partner’s 1NT is interfered with a bid, following bids by us are Lebensohl convention:
·        X                                       Penalty
·        2 level bid                          Natural, weak to play
·        3 level bid                          Natural, forcing to game
·        Cue Bid opponents             Stayman, no stopper in opponents suit
·        3NT                                    Game force, no stopper in opponents suit
·        2NT                                    Lebensohl – Forcing opener to bid 3C
In above sequences where Cue Bid or 3NT indicating no stopper, it is up to opener to change to appropriate suit or bid NT or leave it at 3NT with stoppers.
Purpose of the 2NT Lebensohl is to describe other situations not covered above such as:
·        To sign off at 3 level (when it wasn’t possible at 2 level) with a weak suit
·        To bid Stayman and tell partner that we also have stopper at opponents suit
·        To bid 3NT game force and tell partner we also have stopper for opponents suit
·        To show a natural suit with invitational values
Responder’s rebid after 3C by opener to describe above situations are as follows:
·        Any bid below 3 level of opponents suit = sign off (if C is our suit, responder will simply pass)
·        Any bid at 3 level above opponents suit = natural & invitational
·        Cue bid opponents = Stayman with stopper
·        3NT = Game force with stopper
Notice difference between Cue Bid and 3NT bids when is done immediately after interference or after 2NT Lebensohl (slow bid). An immediate bid shows no stopper and a slow bid shows stopper.
 
Bids over opponent’s weak 2s – including Lebensohl in response to partner X over opponents weak 2
When opponents open a Weak 2 (if 2D indicates long major, we should usually wait until they reveal their major suit. However we can use “double” to show a weak D hand, or bid 3D with opening and good D suit). Before looking at Lebensohl, with following hands we bid:
·       With 15-17hcp, stoppers, we bid 2NT
·       With Good 5 or 6 cards in a suit (in particular majors), 11-15 points we bid it
·       With very strong hand or opening hand with shortage in their suit we use take out double.
·       If 2D is weak major, we can double with weak hand and long D
·       If 2D is weak major, 3D is opening hand and good D
·       All jumps are constructive and show strong hands. Over 2H, 3S bid shows 6 cards suit, for example S AQJ1087 H 3 D K2 C AJ108
·       Leaping Michael – Shows 5 cards in bid suit and 5 cards in other major. For example a bid of 4D over 2H, shows 5 Diamonds and 5 Spades
·       Cue Bidding – asks partner to bid 3NT with stopper in the opponent’s suit.
Over opponent’s weak 2 in major when partner use take out double, Lebensohl convention enable us to find the optimum bid and communicate stoppers, fit, strength, and even try for slam with single suited or two-suited hands. Similar to Lebensohl with 1NT, a bid of 2NT in response to partner’s take out X, asks doubler to bid 3C. Unlike 1NT variation, doubler is not forced to bid 3C after our 2NT bid. If doubler has very strong hand, she can refuse 3C bid and bid her own suit. In this case we should not pass (even with 0 point). After partner doubles a weak 2 bid, following are our choices:
If we have very weak hand (0-6 points):
·       A bid at 2 level if possible is sign off (e.g. 2H-X-P-2S is weak and sign off)
·       2NT forces partner to bid 3C (Lebensohl). We pass with C as suit or bid of another suit at 3 level (that wasn’t possible at 2 level above) is also weak and sign off
·       If doubler decline to bid 3C after our 2NT and bids another suit, it is natural and indicates a very strong hand. This is forcing and we must bid again, even if we are very weak. Doubler with just a little help from us probably has game.
With medium strength 7-10 points, responding to partner’s double:
·       Our bid at 3 level is natural but not necessarily forcing. Doubler can pass with minimum or bid on with extra values.
·       If our suit is higher than opener’s suit we can show exactly 4 card or 5+ as follows:
o                             If we bid at 3 level it shows 5+ card and medium strength (e.g. 2H-X-P-3S shows 5+S and 7-10 points)
o                             If we bid 2NT and after 3C by partner, bid the suit at 3 level. This shows exactly 4 card suit and medium strength hand (e.g. 2H-X-P-2NT-3C-P-3S shows 7-10 points and 4 spades )
With 11+ points
·       We can simply jump to game or bid at 4 level (standard bidding) to show our strength.
·       Immediate 3NT bid (e.g. 2H-X-P-3NT) shows good stoppers in the opponent’s suit. Direct jump to 3NT usually denies 4 card in the other major.
·       Looking for 3NT or slam try with single suited hand:
o                             Immediate Cuebid (2H-X-P-3H) Asks doubler to bid 3NT with a stopper.
o                             If after cuebid, we bid a suit at 4 level, we have one-suited hand with interest in slam (2H-X-P-3H-P-3NT-P-4S/or4Cor4D shows slam try values with one long suit)
·       2 suited majors or minors. Immediate jump cuebid:
o                             If weak 2 is a major (2H-X-P-4H) = both minors
o                             If weak 2 is weak D (2D-X-P-4D) = both majors
·       Showing 4 cards in the other major, with & without stoppers:
o                             2NT and then cuebid (2H-X-P-2NT-P-3C-P-3H) = 4 cards in the other major but no stopper in the opponent’s suit (partner’s choice to play NT or suit)
o                             2NT and then 3NT (2H-X-P-2NT-P-3C-P-3NT) = 4 cards in the other major with one stopper in the opponent’s suit (partner can select to play suit or NT)
·       Use of Lebensohl for slam try with 2 suited hands
o                             2NT and then jump to 4C or 4D (2H-X-P-2NT-P-3C-P-4C or 4D) shows 2 suited hand in the other major (in this example S) and bid suit (with C or D) and slam interest
o                             2NT and then Cuebid opponent’s major at 4 level (2H-X-P-2NT-P-3C-P-4H) shows both minors and slam interest
Points to remember:
Cue bid of opponent’s suit always indicate 11+ hcp
·       Immediate cue bid, asks for NT contract
·       Jump cue bid indicates both majors or both minors
·       Cue bid and then suit at 4 level, single suited slam interest
·       2NT and then cue bid, 4 card in other major & no stopper
Summary of bids to show other major
·       2 level = very weak suit
·       2NT and then 3 level below opponent’s suit, very weak
·       Immediate 3 level = 5 card and 7-10 points
·       2NT & then 3 level above opponent’s = 4 card, 7-10 hcp
·       4 level bid = 5 card, 11+ hcp
·       2NT followed by cue bid = 4 card, 11+hcp, no stopper
·       2NT followed by 3NT = 4 card, 11+hcp, stopper
 
Special bids over 3 & 4 level pre-empts
Over opponents 3-level pre-empts:
·       4NT over 3H or 3S shows minor suits
·       Cue bid over major shows 5 cards in the other major and 5 cards in a minor
·       Cue bid over C or D shows 5/5 in majors
Over 4 S pre-empt:
·       X = 3 suited take out with shortage in S
·       4NT shows any 2 suited hand (5/5 at least) Partner will assume suits are minors and give preference. However if you convert 5C to 5D, partner knows that your suits are D & H.
 
Voidwood/Exclusion Keycard Blackwood
After trump suit is established a bid at 5 level in unbid suit is Exclusion Blackwood with following responses:
·         First step: shows 0 keycard
·         2nd Step: 1 keycard no queen
·         3rd step: 1 keycard and Queen
·         4th step: 2 keycards no queen
·         5th step: 2 keycards and Queen
 
Reverse Smith Peters (Smith Echo)
This is a technique employed by either defender to indicate ‘attitude’ regarding the opening lead against a no-trump contract.
 
How does it work? The principle is very simple. On the first trick played by declarer, whether it is led from dummy or from his hand, either defender can play a low card to say to partner ‘I like the suit originally led’. Conversely an unnecessary high card would say ‘I‘d prefer you to switch to a suit different to that originally led when you get the lead’.

After partner shows a reverse such 1C-1H-2D or 1D-1S-2H; responder bidding of the cheaper of the 4th suit or 2NT is showing a minimum hand (2S and 2NT in above examples) and likely to pass next bid. All other bids are GF. Example
1C-1H-2D-2S is showing minimum
1C-1H-2D-2H showing 5 card H GF
1C-2H-2D-2NT/3C/3D all game force
 
Maximal
After (1x opening by opponents)-Partner overcall-Raise by opponents-Pass by me:
·         Partners X shows 16+, no stopper in opponent’s suit
 
Change of suit after partner opens pre-empt at 3 level is forcing.
 
Competitive bidding
Level of contract to compete to be strictly based on “Total Tricks”.
If partner overcalls H (e.g. LHO opens 1D, partner overcalls 1H and RHO passes), our bids in support of H are:
·       2H, bad raise with only 3 trumps
·       2D, good raise with 3 trumps
·       3H. bad raise with 4 trumps
·       3D, good raise with 4 trumps
·       4H, weak raise with 5 trumps or a hand that expect partner making
 
Doubles / Redoubles
Reopening Double
Reopen with double with a shortage in the opponents’ suit and pass with length
Bid 2nd suit with 2 suited hands
Over pre-emptive jump overcall, your strong opening bid and shortage, double
Over 1 level overcall, double but bid 1NT with 1NT values and stoppers in overcaller’s suit,
Snap-Dragon Double
Partner overcalls and RHO bids. Our double shows 2 cards in partners’ suit and 5 cards in the unbid suit
Redouble by overcalling team
Partner overcalls and RHO doubles. A redouble by you shows a 2 card holding in partner suits with one honor and values such as 7-10hcp.
Support Double
You open the bidding & partner respond and RHO overcalls. Your X shows exactly 3 card support for partner’s suit.
Similarly if you open the bidding & partner responds & RHO doubles, a redouble by you shows 3 card support for partner’s suit.
Game Try Doubles
In competitive bidding, if we feel there is potential for game:
·If there is no room at all to make a game invitation bid, then a X is “Game Try”
·If we have an available bid, then bid is “Game Try” and X is for penalty
 
Unusual NT – As overcall shows 2 lowest unbid suit. – if opponents agree on a major contract, a Sudden bid of 2NT, 3NT or 4NT is indicating 2 suited minor hand and asks partner to bid best minor fit.
 
Bidding after unusual 2NT interference
After 1H/1S and 2NT by opponents:
3C indicates H & 10+ points (if partner’s suit is H, 3+H support & if S, 5 hearts)
3D indicates S & 10+ points (if partner’s suit is H, 5 spades and if S 3+ S support)
 
Bidding over opponent’s 2NT (weak minors)
·       X = 16+ and a good minor, no 4-4 in majors, any subsequent X is penalty
·       3C = 11-15hcp 4+/4+ in majors
·       3D = 16+hcp 4+/4+ in majors
·       3H/3S 12-16hcp good 5+ card and denies the other major
·       3NT to play
·       4H/4S 8 to 9 playing tricks
·       X and then 4H/4S 10+ playing tricks
 
Puppet Stayman after strong NT opening
After 2C/2D/2H/2S following by 2NT showing strong balanced hand, we use 3C Puppet Stayman as follows:
In response to 3C Puppet Stayman:
·         3H/3S 5 card suit
·         3D = No 5 card major but at least one 4 card major, responder bids suit that he doesn’t have or
o        4C both majors 10+ points
o        4D both majors < 10hcp
·         3NT no 5 or 4 card major
2NT à 3S = both minors, long
2NT à 3NT = 5 spades and 4 hearts (no slam interest) (with 5H and 4S, partner can transfer to H and then bid 3S)
2NT à 3C à whatever à 3NT shows no 4 card major, just couldn’t bid 3NT first time (as immediate 3NT shows 5S and 4H)
2NT à 3D transfer to H
2NT à 3H transfer to S
 
Barron to bid slam after strong NT opening
In following situations when potential for slam, don’t use Stayman
After 2C/2D/2H/2S following by 2NT showing strong balanced hand and after 1C-INT-2NT opener showing 15-17 balanced hand: Responder with a balanced hand add his points to opener’s minimum points
·         If total is 30-bad 32, responder bids 4NT
o        Opener passes with minimum and accepts with maximum or good minimum. The acceptance bid is Barron, meaning you start bidding your lowest 4 card suit. Both sides do that to see if a fit is found (4-4) in which case a 6 level slam is bid in that suit. If opener has a 5+ suit he bids 6 in it straight away. If no Barron fit is found 5NT is reached, to be passed.
·         If total is 32-33 points, responder bids 5NT
o        This is forcing to 6NT. An immediate Barron sequence starts with the same objective to reach 6. If no fit found 6NT is played. The bid says no grand slam likely as limited to 34 points. The bidder of 4NT-5NT will have only 4 card suits or a very weak 5 card
 
 
 
Bidding Sequences
 
1H-2H-2NT by opener shows 15-17 typically a 5-3-3-2 hand
·         We can use loosing suit try as above
 
1D-1H-2H-2NT (by responder shows 11+ point and forcing for 1 round), opener bids:
·         Bids games with 13-14 points
·         Bids 3H with 11-12 points
·         Bid game if singleton or void
 
1H-1NT-2NT shows 18-19 hcp forcing to 3C after that opener bids:
·         3H shows 6 card H and asks responder to bid 4H with 2 card support
·         3NT without 6 card
 
1S-1NT-2NT shows 18-19 hcp forcing to 3C (unless bids 3H as below) after that opener bids:
·         3S shows 6 card S and asks responder to bid 4S with 2 card support
·         3NT without 6 card
·         3H by opener showing 4 hearts (with 5 hearts, sequence would be 1S-1NT-3H)
·         If responder bids 3H rather than 3C, is showing 6 cards in H for an alternative game choice
o        Opener can bid game in H or still bid 3S showing 6 cards in S
 
Opposition bid to two level in a suit and partner X for take out:
(1S) – (2S) X – 2NT by you shows you can play in 2 suits, we bid from low
 
After 1H – 2x or 1S – 2x, opener always bids (with following exception) 2H or 2S. This is not promising 6 card minimum and is simply a waiting bid and it is forcing. Responder then describes his hand as follows:
1S        2x
2S        After that:
·         3C/3D better hand, values in C/D but denies 2 card S support
·         2NT minimum hand
·         3S 13+ GF and exactly 2 spades opener to bid 4S with 6 spades and 3NT with 5
·         3NT 15+
 
1H – 2C/2D – 3C/3D, opener to bid this as opposed to 2H with 3 card in C/D with one honor. This is non forcing
 
Following sequences are forcing:
1S-2H-3H is forcing, going to game. If responder interested in slam, can start cue bidding, similarly
1S-2H-2S-3S and 1H/1S-2x-2H/2S is forcing
 
Fit showing jumps
Opponent opens 1 in minor, partner overcalls 1 in major:
·         A 1NT response is 6-10 with max. 2 cards in the overcalled suit.
·         A two level new suit bid is standard, 10+ with a good 5 card + suit, but may be shaded by up to 2 points with a 6 card suit. Trump support will be maximum 2 cards otherwise cue raise should be used if 10+.
·         A 2 level raise is standard, 6-9 with 3 trumps.
·         A 3 level jump in overcaller's suit is weak, 0-5 with 4 trumps.
·         A 2 level bid in opponent's suit is strong (cue raise), 10+ with 4 trumps, or a good side suite, 10+ and only 3 trumps.
·         This is where fit showing jumps with intermediate values (6-9) come in. These are 4 card trump support with 6-9. If you have a suit, jump to 3 in that suit. If you do not have a suit, jump to 3 in opponent's suit. In both cases 4 card trump support is promised and point count is limited to 6-9.
 
Other Tips
 
Take out X of a minor - If short in opponent’s suit, it is OK to bid with 4-3 in majors.
If length in opponent’s suit, should have 4-4 in majors
 
When partner bids to game or at least 3 level in two suits (in particular majors), bid to game or even slam if warranted (inference from bidding).
 
We don’t overcall pre-empt with strong hand
 
6-4 or 7-4 shapes are game winning shapes, we can be aggressive
 
In NT, always lead partner’s bid suit unless you have a rock solid suit of your own with entries
 
In NT, if no bid by partner, we always lead our best suit.
 
When partner bids and we cue bid opponent’s suit, we are agreeing on partner’s suit as trump
 
Pay attention to shape of the hand (flat or source of tricks) when looking for slam.
 
Opponents are sacrificing at 5 level, you may have slam and would like to go to 5 level, cue bid a suit. Partner has to bid at 5 level but this will give additional information to partner to go for slam.
 
If partner bids the same suit again, it shows a 6 card suit (exception is 1H/1S-2x-2H/2S). Bid of NT doesn’t necessary shows stopper in opponent’s suit. For example after 1C – (1D) – X , (2C shows 6 card in C, 1NT shows no 4 card major and not necessarily stopper in D)
 
When we X a part score game by opponents, we should have trumps or brutal force.
 
We don’t let opponents play at 2 level if possible. Partner X after a few passes is take out.
 
In competitive auctions, when opponents bid to 5 level, with 2 aces we X for penalty.
 
On partner’s lead we show attitude. Exceptions are:
·         When dummy is covering partner’s suit – we give count
·         In suit contract when dummy has singleton – we show suit preference
 
Change of suit after partner opens pre-empt at 3 level is forcing.
