====Development after forcing 2 over 1====

1\s - 2\h is discussed [[development after opening of 1 plain suit#1S2H|elsewhere]]

===Opener's first rebid===
  * Opener's //non-forcing// rebids:
    * Rebid of opened suit at the 2 level;
    * Raise of responder's suit to the 3 level (promising 3+ card support)
    * Bid of a \c Canapé at the 3 level
  * Opener's //forcing// rebids; 
    * A new suit at the 2 level
    * A jump shift to the 3 level or to 4\c
    * A jump raise of responder's suit (only if responder's suit is a minor) with 5+ card support (this is keycard "Gerber
    * Ä jump rebid of the opened suit showing a very good suit (one loser opposite a singleton)
    * A jump to 3N showing a strong canapé (only if responder's suit is a minor) in responder's suit
    * 2N with stoppers in the unbid suits and one of the below:
      *  A \c canapé
      * A one suited hand

The 2N rebid by opener (at his second bid) shows either a 15-16 HCP one suiter or a \c canapé with extra values(if the response was 2\c, then the \c canapé is not possible -- opener has a 15-16 HCP one suiter).  Responder's non-forcing bid is a rebid of his suit; all other non-game bids are forcing to game or the four level.

In order to determine which hand type opener has, responder can bid 3\c or 3 of opener's major. The 3\c bid implies a Club fit, the 3 major bid implies a 3 card major suit fit.

After the 3C bid, opener rebids his major if he has the 15-16 HCP one suiter. Any other rebid by opener shows the \c canapé.

After the bid of 3 of opener's major by responder, 3N shows the Club Canapé (as would a bid of 4\c).
