-===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).

-The 2\h response to 1\s is constructive, but non-forcing.
-The auction develops as follows:
-^^^
-|2\s|not encouraging|
-|3\c/3\d| is natural (in the canapé sense) and forcing|
-|3\h|is encouraging|
-|3\s|is very encouraging, but denies 3\hs|
-|2N|is a contract correcting call "forcing" a 3\c rebid by responder|
-|3N|is a strong hand with a \H canapé|
-**After 1\s - 2\h - 2N - 3\c**
-^^^
-|3\d|is final |
-|3\h|is a maximum hand with 2\hs|
-|3\s|6\s and 3\hs, maximum hand (forcing) |
-|3N|Maximum hand with 3\hs (not forcing, but seems unlikely that responder will pass)|
