Sob Stories


1. “I didn’t open the bidding with 15 HCP because I didn’t have a good

rebid.”

2. “I don’t know what to rebid.” (After staring at hand for 2 minutes.)

3. “I didn’t know what to rebid and passed. We missed the cold slam.”


Opener’s Rebid Options (Opening 1 of a suit)


The following options are based on no opponent interference bids.

Because if they do, it’s a whole new ballgame.


1. Rebid your suit with enough cards in your suit to do so.

2. Support partner’s suit when you know that there are at least 8

cards in that suit between the two hands, preferably in a major.

3. Rebid notrump when you don’t have that 8+ card fit.

4. Rebid a 4 card major if partner hasn’t denied 4+ cards in that

major, per up-the-line responses.

5. Rebid a second suit which has 4+ cards.

6. Make a 19+ HCP jump shift to a second suit.

7. If partner supports your suit, either pass, rebid to invite game

or rebid game.


Scope of this Handout


This write-up will only explain the rebids of options 1 and 3, which

do not involve:


1. some sort of support for responder’s suit (see 2)

2. some sort of support for your suit (see 7)

3. slam invitations per 19+ HCP hands (see 6)

4. offering a second suit (see 4 and 5)

Introducing the 6/16 Precept: Part 1(the 6)


Whatever suit you open at the 1-level, Standard American bidding

conventions say you must (should) have 6+ cards in your opening suit to rebid it, major or minor. This rule applies as long as the opponents have not bid a suit. Note that a takeout double by an opponent is not a suit bid.


This standard 6+ card rule is the 6 in the “6/16 Precept”.


Examples:

Cards Partner Opener Cards

Open in Suit Responds Rebids in Suit

-------- --------- -------------- ---------- ---------

1 club 2+ at 1-level 2 clubs 6+

or

3 clubs 6+

1 diam 4+ at 1-level 2 diams 6+

or

3 diams 6+

1 heart 5+ at 1-level 2 hearts 6+

or

3 hearts 6+

1 spade 5+ at 1-level 2 spades 6+

or

3 spades 6+


So the rebid (without interference) of your opening suit indicates a 6+ card suit.


The 6/16 Precept: Part 2 (the 16)


In all the examples above, the only difference between the 2-level rebids and 3-level rebids would be your HCP count.


2-level suit rebids indicate 11-15 HCP.

3-level suit skip rebids indicate 16+ HCP.

The 6/16 Precept: Part 2 (continued)


The 16+ skip bid in your suit is the 16 in the “6/16 Precept”.


NOTE: You skip to show HCP, not to show more cards in the suit.


Applying the 16 of the 6/16 Precept to Notrump Rebids


If the opener rebids notrump without skipping, he is indicating

about 11-15 HCP. If he skips, he indicates about 16 HCP. Sounds like

the suit rebid precept doesn’t it?


Examples:

Partner Opener

Open Responds Rebids HCP

---------- ---------------- ------------------ ------------

1 club at 1-level 1 notrump 11-15 (same as 6/16)

(6-18 HCP) or

2 notrump 16-17 (same as 6/16)

or

3 notrump 18+


1 spade at 2-level 2 notrump 11-13 (near to 6/16)

(10-18 HCP) or

3 notrump 15+ (almost 6/16)


Example 1: The 2 notrump (16-17 HCP) needs more than partner’s

minimum of 6 HCP to bid game (25 HCP). It is a game

invite.

The 3 notrump (18+ HCP) doesn’t.

Yes – 18 + 6 is only 24, but you wouldn’t make an invite

bid for only one more HCP from partner.

Applying the 16 of the 6/16 Precept to Notrump Rebids (cont.)


Example 2: The 2 notrump (11-13 HCP) needs more than partner’s

minimum 10 HCP to bid game. This is a game invite.

With 14 HCP you could bid 2 notrump or 3 notrump based

on your declarer skills.

The 3 notrump (15+ HCP) with partner’s minimum of 10

HCP is enough for game.
