4. REBIDS

You opened as in Chapter 2. Your partner responded as in Chapter 3.  If this opening and responding did not finish the auction,  your and your partner's subsequent bid is called rebid.

  • See Section-3 for rebids after Weak-Two openings
  • SeeSection-5 for rebids after Strong-Two club openings
  • See Section- 8 for rebids after 1 NT opening (Rebids in Stayman and  Transfer conventions)

Here are two hints for you:

1- You may rebid your suit with 6 cards. 
2- Below bids from either by opener or responder are limiting:

     a) Bidding previously bid suit 
      b) Bidding NT
     
      You can also limit your hand at any level that will reflect your point range.  
     It is your partner's duty to take the partnership to any contract after you 
     showed your limit... Here are some limiting examples:

1D-1H
2D

1H-2H 1H-3H 1H-4H

4.1 Opener's Rebids

An opener may open the bidding with 13-21 points at the 1-level. So, 13 points is opener's minimum, 21 points is opener's maximum points. We can categorize opener's points in strength as: 

13-15 points: opener's minimum strength
16-18 points: opener's medium strength
19-21 points opener's maximum strength

Responder may support opener, may suggest a new suit or proposes a notrump contract
, according to his points. No matter what is responder's response, as a 1-level suit opener your rebid (second bid) must reflect your points range.

In order to rebid your opening suit, you must have at least 6-cards in that suit. 5 card suit is acceptable if you have no other choice..

Also, if you will support your partner's (responder's) suit, you must revalaute your total points, by using your short-suit points (see Section1)

4.1.1 Opener's Rebids With Minimum Strength

Opener's Point Range

Opener's Rebid

Example
(click on the example)

13-15

Raise responder's suit at the cheapest level. You need at least four cards for raising.. Bid your four card major before raising partner's minor..

Rebid NT at the cheapest level.

Rebid a new suit (If you will bid the new suit at the two level, the rank of new suit must not be higher than the first one. See note.)

Rebid your -opening- suit at the lowest level.

If partner replied 1NT, that means that there is no fit in any higher rank suit than yours.. You can pass, rebid a new 4+ card minor or rebid your six card major..

A new suit by an unpassed responder is forcing one round. But, new suit rebid by opener is not forcing.

Note: Reverse: If opener's rebid is higher in rank than his first suit, this is called "reverse". For a reverse bid you need 16+ points. Opener's rebid at the level one is not reverse.

16-18

If you have support, jump raise responder's suit..

Rebid a new suit (The rank of new suit can be higher than the first one)

Jump Rebid your -opening- suit.

Note: If you have 18 points,  jump in notrump. Example
1C-1H
2NT-?
If partner responds 1NT, your rebid is 2NT with a balanced hand and 18 points
1C-1NT
2NT-?
Responder will understand you are greater than 1NT(15-17) opening and less than 2NT opening (20-21). 
You would pass with minimum
You would open 1NT with 15-17
You would open 2NT with 20-21

1C-1NT
2NT-?
Responder will understand you are greater than 1NT(15-17) opening and less than 2NT opening (20-21).
You would pass with minimum
You would open 1NT with 15-17
You would open 2NT with 20-21





4.2 Responder's Rebids

Responder's rebids depend on his first bid and opener's rebid. If responder determine that partnership has totally 25+ points, he must keep bidding until  game or  slam. As a responder your minimum point is 6. As a responder you must evaluate your hand within below ranges, if you are preparing to rebid.

 6-10 : Responder's minimum point range.
11-12: Responder's intermediate point range
13+   : Responder's maximum point range.

Opener's rebids indicate his point ranges: 13-15, 16-18 or 19-21. According to opener's rebid, responder can decide if contract will be a partscore, game or slam.

A responder preparing to support his partner's suit, must reevalute his hand by addding his short-suit points to his high card points to find his total points. In order to be included in this point count system voids, singletons and doubletons must be in a suit which partnership didn't bid until then. 

You may rebid your suit with 6+ cards.  

Keep in mind that
a) Bidding previously bid suit 
b) Bidding NT
are limiting bids..

Responder also has some tools for forcing: Jump shifts, "Forth Suit", cuebidding etc..

6-10

 

Responder's rebids with 6-10 points are called responder's minimum rebids.

If opener shows minimum hand,

If you compare your points with partner's points you will see that you don't have enough points for a game:So, you can pass.
If you don't want to pass you must stop  at the best part score contract: If you have controls in unbid suits you may bid 1 NT without support to partner's suit..
or you can rebid partner's suit. You may rebid your suit with 6+ cards. Avoid rebidding your 5 card suit if opener shows two suits (an unbalanced hand).

If opener shows medium hand,

If you have only 6 points you can pass. If you have 7-8 points you may invite your partner for a game contract by bidding one of partnership suits at the 3 level.
With 6-10 points against a partner with 16-18 points you can also bid a new suit.

If opener shows maximum hand,

With 6-10 points against a partner with 19-21 points game is sure. If partnership already reached a game you can pass.

If you did not reached  a game yet, bid a game with support for partner's suit.

If your  partner made a jump bid, you can bid your suit:

   Opener      Responder
1             1
2             3

Responder's Rebid

Example
(click on the example)

11-12

Responder's rebids with 11-12 points are called responder's intermediate rebids.

If opener shows minimum hand,

1) If you have controls in unbid suits you can bid NT.
If opener has 14 or 15 points game is possible.


2) You can bid a new suit.

Note: If you respond in a major to your partner's minor opening, opener can bid 1NT. A 1NT rebid by opener denies 4+ card support in your major suit. But she may have 3 cards and those three cards may carry you to a game in your major. If you want to learn if opener (whose rebid was 1N after your major response) has 3 cards in your major suit you must rebid the other minor (other than partner's minor). This convention is called NMF- New Minor Forcing Convention. New minor asks if partner has at least three cards in your major suit.

3)You can bid your or partner's suit by jump.

If opener shows medium hand,

Bid a game. If you need some more information from the opener (your partner), you may bid a new suit.

If opener shows maximum hand,

If you need some more information from the opener (your partner), you may bid a new suit. Slam possible








4.2.3 Responder's Maximum Rebids

Point 
Range 

Responder's Rebid

Example
(click on the example)

13+

Responder's rebids with 13+ points are called responder's maximum rebids.

Responder's fourth suit bid is a game forcing bid. When opener shows two suits, he may not have room for a fit in another suit.. For this reason responder's fourth suit bid is artificial and a game forcing bid. ... In 1C-1H;1S-2D sequence 2D bid by responder is 4th suit forcing.. 4th suit forcing does not apply in an "up the line" bidding sequence at the 1-level, e.g., 1C-1D-1H-1S
If responder bids a fourth suit, opener must provide additional information by;
• Raising responder's first suit with three-card support
• Bidding NT with a stopper in the fourth suit

Cuebidding technique (Bidding opponent's suit) can also be used for forcing..

If opener shows minimum,

1) If you have controls in unbid suits you can bid 3 NT.
2) Bid a game in partner's or yours suit. If you are going to bid game in your suit which is not supported by partner, your major suit must be 6-7 carded, your minor suit must  have at least 7 cards.
3) A new suit is always forcing: So you can bid a new suit to get more information from partner. If partner made a limit bid (like 1NT,
previosly bid suit etc.), you can  jump shift to a new suit to show your partner your intension for a game. The lenght and strenght of this new suit is not very important. 

If opener shows medium,

1) Bid a game in partner's or yours suit. If you are going to bid game in your suit which is not supported by partner,  your major suit must be 6-7 carded, your minor suit must  have at least 7 cards.
2) If you found 33 total combined points, slam is possible: If you are not sure about slam yet, you can invent a new suit.  A new suit is always forcing: Partner can not pass. So you can get more information from partner before a good slam contract. Jumping to game level in either partner's or your suit invites partner to slam....

If opener shows maximum,

Slam is always possible. Read Section 7 for slam biddings...
