    Opener passes with minimum or shows aces stepwise starting from 5 = 0 bidder can then signoff in NT or bid Kings upwards.

    Note 2: Responses to 1 Opening

    1NT response shows five hearts. 2

    response shows no five card major (2

    then asks for fourmissing four card majors). 2 response shows five spades. 2 responses show a seven-card major.Thee level jumps name the suit and ask for key card RKCB. 2NT is a slam try with both four cardminors, 4432 shape 12+, with 20+ opener can just bid 6NT, with a little fewer he can accept a minorRKCB or suggest a five card major.

    Shows no five card major but otherwise any shape.

    Common rules to note when responding to all one level openings are:

    2NT is forcing without intervention or over a 1 level overcall or double.

    After one of a suit openings, three of a suit names the suit and asks for controls showing a good sevencard suit looking for a slam.

    Two level jump responses are six or more card and game forcing.

    1* (X) XX 10+ 4 Can play in clubs if they don't pull it, if they do penalty trapensues

    All other responses remain the same

    Responses to 1*f opening 16+

    Our responses are aimed at establishing whether we should be in game, part-score or slam veryquickly. This means we can make 1NT when everyone else goes off in 2. It also means we caninvestigate slams below game level and make 4 when everyone else goes off in 5.

    In a game forcing auction, any suit agreement below game is Roman Key Card Blackwood. Raising aminor to the four level in a constructive auction is also RKCB. If the agreed suit is a minor we alwayshave the ability to sign-off in 3 or 4NT.

    Also, unlike Precision or a lot of other artificial systems, our responses aim to establish whether we

    have the balance of points quickly, the 1 response immediately saying that we have at least 22 HCP.Once we have done this we will not let the opponents play in any un-doubled contract, a conventionthat we term a penalty trap. Pass is forcing and shows a doubleton in their suit, and X is penaltyoriented and shows three cards (or four cards at the two level). This is especially useful at match pointpairs where 200 if often a world wide top.

    Lastly, we deal with intervention at the three level by assuming we have the balance of points and startthe same penalty trap immediately.

He canalso "break transfer" by bidding a five card suit below the transfer suit regardless of support. Breakingtransfer to a suit above the transfer suit show a singleton or void in the transfer suit and a five card suit.Breaking transfer to 2NT*g shows a shortage in the transfer suit and four cards in the other majorallowing responder to accept this major at the three level.

    Dealing With Intervention

    Mirror responses are preserved when the opponents X or overcall 1/. This is done by either using X

    or XX as a game force when available or 1*g where it's not. When the opponents intervene with Xor 1 the 1* response is weakest and responses get stronger the lower they get, pass being semi-positive. Over 1 X is the weakest response with pass again as any 6 or 7.

    After overcalls below 1NT and a pass by responder we have shown 22+ and a penalty trapoperates ifthe opponents bid further.

    After overcalls below 1NT and a response other than pass we have not demonstrated that we have 22+.If the opponents bid further natural bidding occurs overcalls and passes are non-forcing and X istakeout. If opener has a game force or possible game he will need to jump, cue or X for takeout and

    then make a subsequent bid.

    1NT Opening Bid 9-11 HCP

    We are allowed to open 1NT with shapes 4333, 4432, 5332, 5422, 6322 and also 4441, 5431, 6331 witha singleton minor. Five card majors are not opened 1NT but are opened 2 of a minor instead. 1NT can

    be 9-13 in third and fourth since partner has shown fewer than 12 points, 2 response is natural by apassed hand.

    The range allows us to open the most frequent three point range and never to play in 2NT the graveyard contract.

    Since most systems feature five point ranges for suit opening bids when they re-bid their suit, it seemsreasonable to apply the same degree of accuracy to 1NT given that is has such a positive expectation,particularly at pairs where 'failing' to bid game may often get you a top.

    Jones 2Relay Response

    This is another game forcing 2 relay. Obviously, as opener is weak, transfers are less attractive - butthey also give the opponents more chances to intervene since they can bid directly over the transfer orafter the transfer is completed to show a balancing hand. All games forcing hands go through this bid,the question is whether to stop in game or slam.

    Responder's bids after opener replies 3g are very similar only it's a game forcing auction.

    Defence to Penalty Double of 1NT

    It is important to have a good pull of 1NT when doubled, the following is simple and effective...

    Opening Response Points

    1NT (X) Pass*f 0-12 forcing, no five card suit, asks opener to bid a five cardsuit or XX then responder normally bids suits upwards

    but can also bid a suit then re-double to show a take-outof that suit. You can also pass the XX with 9-12.

    2 0-12 five or six card

    XX 13+ see penalty trap see TNT

    2NT 0-12 55 in the minors

    3 0-12 seven card pre-emptive

    3NT 15+ Bit odd but 3NT is always natural to save confusion

    4 0-12 seven card, pre-empts

    Defence to Over-calls

    After minimum intervention 2/3NT are natural with a stop, a cue bid shows a stop for 3NT but with amajor suit wanting to find a fit. Jump bids below 3NT are five card natural with a stop. So strongdirect bids show a stop and bids via a X deny a stop.

    Opening Overcall Response Points Length

    1NT (2) 2 0-14 5 competitive

    2NT 13, 14 Stop in hearts

    3 0-14 6 competitive

    3*g 15+ four card spades with a stop in hearts

    3*g 15+ 5 shows a stop

    X* 0+ competative takeout or a game force

    without a stop, coming back with a bid of3 or above confirms the game forcingtype.

    3NT 15+ natural with a stop

  • 7/30/2019 Strong Diamond Card March 2013

    27/32

    4 0-14 7 weak - X first then jump for RKCB

    We're using a two way double that is either a weak takeout shape or shows a game value hand without a stop.

    Opener assumes the first and bids length before strength. With little preference between the suits at the next

    level opener can use scramble.

    Opening Overcall Response Opener Length

    1NT (2) X* 2 4 denies a five card minor since we'rebidding length before strength

    2NT Scramble asking the doubler to pick hisbest at the next level. Here it asks forhis better minor, over 2 it would ask

    for his better of all three suits.

    3 4+ four card

    If the doubler is strong he will come back with a bid of 3 or up showing a strong hand without a stopin hearts. 3 would show four card spades but no stop, 3 would show five card spades with no stop,3NT would show both minors with no heart stop.

    2 Five Card Major Pre-empts

    The Jones Strong Diamond System is designed for pairs and in pairs major suit contract tend to scorevery well when they make. Using two clubs to show five hearts and two diamonds to show five spadesallows you to bid both five and six card majors accurately. The frequency of these five card major bidsis much higher than regular six card weak twos. You also have the ability to pass the bid out or sign-offat a minimum level when you hold a singleton in partner's major.

    The bid should show at least one of the top three honours to five when vulnerable. It is not made witha six card suit.

    After and overcall X is used for all 15+ hands. After a X XX shows all 15+ hands. This leaves all otherbids as weak hands with long suits and cue bids as Michaels and NT as UNT.

    29/32

    Shows 7-9 and either six card minor non-vulnerable or seven card minor vulnerable. Partner bids aminor asking for opener to pass or correct. Majors are forcing with a good five or six card suit, openershould support with two card support or bid 3NT with a shortage in the major. A 3NT response wouldshow something like a 18 count and stops in both majors and a minor.

    Wild Threes and Fours

    Three level are 0-5 with a five or six card suit. Vulnerable you will have a six card suit or 55xx in twosuits. At the 4 level these are 7 card suits 0-7.

    All bids by partner are non-forcing and naturalexcept 4NT RKCB.

    Notice that you need a very big hand to bid 3NT about 22+.

    You can raise a minor non-vulnerable with four card support but majors should generally have fivecard support for a pre-emptive raise.

    If you are 55xx open the lower suit so you have an escape route if the double gets passed round.

    3 (X) Pass (Pass) 3 would show 55 in the two suits.

    Notice that we are not bothered about minors scores being lower at pairs since we don't expect to makethe contract and will generally be scored against the opponent's playing the hand.

    Rationale of Wild Pre-empts

    The theory of wild pre-empts is that with 0-5 you expect the opponents to be in game purely from ahigh card point of view and should hit them as hard as you possibly can from your first bid. It is truethat you might also hit your partner but you only have one partner and there are two opponents.

    Also the statistics of fits are on your side because the vast majority of hands have an eight card fit andthe average fit on a random hand is 8.9 cards. Now I don't follow the law of total trick religiously butthis means that you generally have enough trumps to play at the three level even when doubled. If notdoubled the law of total tricks is irrelevant and with the routine use of take-out doubles it is hard tofind a penalty.

    Alan Mould's 1998 book "Pre-empts A common sense approach to the hows and whys of pre-empts"introduces the concept of wild pre-empts. He gives this hand...
