Opener’s 2^nd bid called REBID often fairly reflects the shape and strength of his hand.

Important Notes:

1. Responder’s 1^st bid strength is classified as Minimum 6-9 points, Invitational 10-12 points and Game Forcing 13+ points. Add 6  to these limits to deduce opener’s 2^nd bid strength. Therefore,
   • Opener’s hand is Minimum when 12-15 points
   • Invitational 16-18 points
   • Game Forcing 19+ points
2. We play reverses to show invitational strong opening hands. Plan your 1^st opening bid in such a way that when you have 12-15 points minimum hand, the 2^nd bid DOES NOT become a reverse. Wherever, such situations are unavoidable, bid your 2^nd best option or 1NT.

Following chart chronologically lists various combinations of opener’s 2^nd bid, when FIT is not achieved after responder’s 1^st bid.

a, b, c are suit strains in the ascending order. NT – No Trump and x- Suit or NT

1 Major (1!h/1!s) opening hands receiving 1NT forcing response

Such hands are required to be 100% forcing. Opener can’t pass. In situations where opener has nothing new to show, he can bid 3+ cards minor.

Bridge grammar has designed this protocol to facilitate 2 over 1 game forcing. As 2 over 1 game forcing requires 13+ points for bids at level 2 of a lower strain.

Regular opening hands

12-15 Minimum	1b : 2c	1x	1!d : 1!s : 2!c	Non Forcing. Avoid reverse.
12-15 Minimum	1a : 2b	1b	1!d : 1!s : 2!s	Non Forcing b is 4+ cards and FIT is found with 4 cards in opening hand.
16-18 Invitational	1b : 3a	1x	1!h : 1!s : 3!c	Non Forcing.
16-18 Invitational	1a : 3b	1b	1!d : 1!s : 3!s	Invitational. Jump a level in responder’s suit. Opener has 4+ cards in b suit.
16+ Invitational	1a : 2c	1x	1!c : 1!s : 2!h	Forcing. Reverse Rebid
19+ Game Forcing	1b : 3NT	1NT	1!h : 1NT : 3NT	Game Forcing in 3NT

Foot Note – After opener’s rebid, if the decision to bid a game is still inconclusive, two notable conventions can be used by responer:

• Fourth Suit Forcing-Game Forcing
• New Minor Forcing–one round forcing
