Annotations by Rhoda Walsh on the 1 Notrump game forcing  response in the “2 over 1 game forcing system” (Walsh System).  We publish here the paragraph 6 of Chapter Three. The Chapter Three is devoted to Responder’s Rebids. This is the point Rhoda explains us today: §6. Opener Rebids Three of a Minor: 1/1♠-1NT; 3♣/3. Game forcing jump shift. In the following days we will publish the remaining  paragraphs of Chapter Three and Chapters Four and Five.

 Forcing Notrump

 

Chapter III  Responder’s Rebids

III. §6. Opener Rebids Three of a Minor: 1/1♠-1NT; 3♣/3. Game forcing jump shift

3 by Responder (after a 3♣ rebid by Opener):1/1♠-1NT; 3♣-3. Responder’s 3 bid shows one of two hands:

a) A six or more card diamond suit. 6 to 11 HCP. Denies a three or more card fit for Opener’s major. Game forcing.

b) Showing a stopper for notrump purposes. 6 to 14 HCP. Denies a three or more card fit for Opener’s major. Denies a stopper in the other major. Game forcing.

Opener’s rebids: Opener’s rebid is based on the assumption that Responder is showing a stopper for notrump purposes. Holding a six card major, and a stopper in the other major, Opener has the choice of rebidding her major or bidding 3NT. Her choice will depend on the strength of her holdings in the two majors as well as her outside distribution.

If Responder has a six or more card diamond suit and slam interest, over a 3NT rebid by Opener, Responder rebids 4♦. Game forcing. Slam invitational.

 

3 by Responder (after a 1♠ opening bid): 1♠-1NT; 3♣/3-3. Five or more hearts. 6 to 11 HCP. Denies three or more card spade fit. Game forcing.

 

Three of Opener’s major by Responder:1/1♠-1NT; 3♣/3– 3/3♠. One of two hands:

a) A non-constructive single raise: Three card support for Opener’s major. 6 to 7 PSP. Game forcing.

b) A preference: two card support for Opener’s major. 6+ HCP. Game forcing.

 

3♠ by Responder (after a 1 opening bid): 1-1NT; 3♣/3-3♠. Shows a spade stopper for notrump purposes. 6 to 14 HCP. Denies a three or more card fit for Opener’s major. Denies a stopper in the unbid minor. Game forcing.

 

3NT by Responder. After a 1 opening bid: 1-1NT; 3♣/3-3NT. 6 to 11 HCP. Denies three or more card fit for Opener’s major. Nonforcing.

a) If Opener rebids 3♣ (1-1NT; 3♣), 3NT by Responder shows stoppers in both unbid suits. Rationale: Responder can cuebid the suit she has stopped (if she has only one of the unbid suits stopped), or give a preference on a two card heart holding (if she has none of the unbid suits stopped).

b) If Opener rebids 3 (1-1NT; 3): 3NT by Responder neither shows nor denies stoppers in either unbid suit; however, it does deny holding a spade stopper while lacking a club stopper. Rationale: holding a spade stopper and not a club stopper, Responder rebids 3♠. Responder has no means of differentiating between a lack of stoppers in both unbid suits, or a club stopper but no spade stopper, or stoppers in both unbid suits.

Note: If Responder lacks a stopper only in clubs or in both unbid suits, she prefers a 3 rebid on a doubleton to the 3NT rebid.

 

3NT by Responder. After a 1♠ opening bid: 1♠-1NT; 3♣/3-3NT (General feature as above).

a) If Opener rebids 3♣ (1♠-1NT; 3♣), 3NT by Responder shows a heart stopper; neither shows nor denies a diamond stopper. Rationale: Responder cannot bid 3 to show the heart stopper and the lack of a diamond stopper since a 3 rebid here shows five or more hearts, not a stopper.

Note:if Responder lacks a diamond stopper, she prefers a 3♠ rebid on a doubleton to the 3NT rebid.

b) if Opener rebids 3 (1♠-1NT; 3): 3NT by Responder neither shows nor denies stoppers in either clubs or hearts. Rationale: Responder may have a singleton spade, and no other available call.

Note:if Responder lacks a stopper in either unbid suit, she prefers a 3♠ rebid on a doubleton to the 3NT rebid.

 

Four of Opener’s minor by Responder:1/1♠-1NT; 3♣/3-4♣/4. Five or more card minor fit. Denies three or more card fit for Opener’s major. 9+ PSP. Slam invitational.

 

Four of Opener’s major by Responder: Delayed limit raise 1/1♠-1NT; 3♣/3-4/4♠. Three card support for Opener’s major. 10 to 12 PSP. Nonforcing.

 

4NT by Responder:1430 RKCB in Opener’s minor (the last naturally bid suit): 1/1♠-1NT; 3♣/3-4NT.
