Jacoby 2NT Modified
Draft
by Glenn Nettleton

A Jacoby 2 NT response to a major opening bid promises a minimum of 12 HCP and 4-card support. This is Jeff’s alternate scheme allowing partners to communicate their holdings more accurately and at lower levels. Responder is in control asking established up the line questions and Opener gives agreed upon up the line answers. If you'd rather have a Word file!

Opener bids 1 of a major and responder bids 2NT.
 Opener: 3 – Min points = 11-14.
  Responder: 3 – I don’t care.
       Opener: 3 – I have a singleton.
           Responder: 3 – What is it?
                Opener: Bids the suit.
       Opener: 3 – I have another 5-card suit.
           Responder: 3NT – What is it?
                Opener: Bids the suit.
       Opener: 3NT – I have a flat hand.
           Responder: Does their thing.

 Opener: 3 – I have a stiff , 14˝ + points.
 Opener: 3 – I have a stiff , 14˝ + points.
 Opener: 3 – The other major is stiff, 14˝ + points.
 Opener: 3NT – I have a flat hand, 14˝ + points.

 Opener: 4 – I have 5 or 6 , 14˝ + points. (See Note 4)
     Responder: 4 – Which?
          Opener: 4 = I have 5; 4 =I have 6.
              Responder: Does their thing.
  Opener: 4 – I have 5 or 6 , 14˝ + points. (See Note 4)
     Responder: 4 – Which?
          Opener: 4 = I have 5, 4NT = I have 6.
              Responder: Does their thing.
  Opener: 4 – I have 5 of the other major, 14˝ + points.
     Responder: Does their thing.

   Notes:
1. Bidding the next suit, say 4, by Responder asks, “How many points?” concluding many of the above sequences.  Opener answers up the line.
  4 = 14˝-16
  4 = 17-18
  4NT = 19-20
2. At any time a jump by Responder initiates queue bidding of controls until the final contract is reached.
3. Evaluating 14 Points: If a bad 14, show minimum, if good show positive.
4. It is correct to open a 5 card major instead of a 6 card minor if minimum.  If minimum + open the 6 bagger.
5. Every bid in the above sequence is alterable.

1 Support Doubles A support double is a way for opener to show responder that he has 3-card support for his major suit response, after interference. Note: a direct raise to 2 of the major promises 4 card support.  Support doubles  ONLY apply by opener at his SECOND turn to bid and if opener could support partner’s major at the 2 level.

Examples:
1 (C or D) - p - 1(H or S) - 2bid - DBL
1D - Dbl - 1S - 2H - DBL

If instead of an overcall, 4th seat doubles, you may play Support Redoubles.
1C - p - 1H - DBL - REDBL
1D - p - 1S - DBL- REDBL

Support doubles and redoubles are alertable. Explain them as “Shows exactly 3 card support.”
New Minor Forcing New Minor Forcing is used only by responder, usually at his second turn to bid. You should have at least invitational strength (a good 10%-11+ pts.). In most cases, you have a 5-card major and want to know whether or not partner has a fit.

After 1D-1H-1NT, you would rebid 2C (forcing one round). Your bid doesn't promise club length or even a stopper -- it only asks opener to bid again and tell you more about his hand, specifically if he has 3 cards in the major already bid.

If you rebid anything but 3 of the bid major, over partner's New Minor Forcing bid, you deny 3-card length in his major. Your second priority is to show an unbid 4-card major. In the example above, you would rebid 2S if you held 2 hearts and 4 spades.

If you don't have 3 spades or 4 hearts, you have to find another descriptive rebid. You can choose 2NT if you have stoppers in hearts and clubs, or 2D if you have a 5-card suit. In all of these cases, partner will now know that you have only a 7-card spade fit, so he can choose the 3NT game.

Opener can show point-count with rebid. After partner bids 2C in the auction above, you would jump to 3H if you had strong 3-card support and a good 14 or 15 pts. If you had only a doubleton heart and a good 14-15 pts., you would jump to 3NT.

Texas Transfer Requirements (after partner opens 1 NT):
These transfer bids are used only when the partner realizes that he holds enough values for game,  not partscore and has no interest in slam. 
Bids:
1. bidding 4 transfers the No Trump bidder to Hearts (Normally 6-card suit)
2. bidding 4 transfers the No Trump bidder to Spades (Normally 6-card suit)
Smolen Transfer After a 1NT opening, shows a good hand with 5-4 majors. First bid Stayman, then after a 2D denial by opener, jump to the three level in the four card suit (so opener will be declarer if the partnership has a 5-3 major fit).  If the responder actually holds six plus cards in Spades, and the No Trump bidder opts for 3 No Trump as the contract, then the responder would bid four of the suit below his long major, forcing the No Trump bidder to bid four of the responders suit.
  Smolen, Extended In 6-4 situation above, bid your short minor over 3NT, showing a singleton or void.  Note: If not careful, can be confused with Gerber request when short suit is clubs.
  Spirals Goes into effect when Opener has bid one of a Minor, Pass, and Responder now bids one of a Major, and Opener raises the Major as in1C or 1D, P, 1H or 1S, P, 2H or 2S.   Responder initiates by making the cheapest call.  

When Hearts are the agreed suit:
   1st Step: 1C, 1H, 2H, 2S:   2NT by Opener shows minimum hand (11-12) with 3 card trump support
    2nd Step:   3C by Opener shows maximum hand (13-14) with 3 card trump support.
     3rd Step:  3D by Opener shows minimum hand (11-12) with 4 card support
      4th Step: 3H by Opener shows maximum hand (13-14) with 4 card support.

When Spades are the agree suit:
      1st Step: 1D, 1S, 2S, 2NT: 3C by Opener shows minimum hand with 3 card trump support.
      2nd Step: 3D by Opener shows maximum hand with 3 card support.
      3rd Step: 3H by Opener shows minimum hand with 4 card support.
      4th Step: 3S by Opener shows maximum hand with 4 card support.

  Unusual over Unusual Part of "defense to 2-suited interference". In response to  Unusual NT, Bergen developed following: After 1Spade   2NT responder bids
3Club= limit raise or better in spades
3= good hand with hearts
3= natural, non-forcing
3= weak, competitive (4 trump, 7+ pts)
Note that if the sequence had been 1   2NT then bidding opener's suit is always "weak, competitive" and first available bid becomes "limit raise or better in openers suit", etc.

If the overcall quebid does not clearly identify the second suit (Michaels over major), then bids in the possible suits are "natural, non-forcing". For example, after 1  2 (Cue bidder has hearts and unknown minor)
3= natural, non-forcing 
3= natural, non-forcing 
3= limit raise or better in spades
3= weak, competitive 
4 Lebensohl over partner's 1 NT open This complicated bidding system is described at http://www.bridgeguys.com/Conventions/Lebensohl.html.

Your Webmaster prefers using stolen bid doubles over 1NT interference and systems on to accomplish the same thing without all the extra things to remember.

2 Lebensohl After A Takeout Double
of a Weak Two Bid
2NT shows <6 points; 3 by Doubler asks for best suit; can pass if best is .  Any other response by Doubler shows strong hand (18+ or equiv).
Any other bid promises 6-9 pts.
0 Quacks Short for Queens and Jacks.  Fine tune your point count by analyzing the number, and support for, your queens and jacks.  If you have more queens and jacks than kings and queens and they are not supported by Aces and Kings, subtract a point from your hand.  If your queens and jacks are supported, consider adding a point.  Excess queens and jacks are more important at suit contracts than NT.  Control cards held by opposition can often result in ruffing out one of your side suit winners.
