-\s - 2\h is discussed [[development after opening of 1 plain suit#OneSTwoH|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).
-===Responder's second bid:===
-  * A preference at the two level back to opener's first bid suit is a non-forcing 3 card preference with a disinclination to bid 2N.
-  * A preference at the three level (with or without a jump) is:
-    * Invitational if opener did not raise responder's suit and did not bid 2N;
-    * Forcing if opener raised responder's suit or bid 2N.  Thus the preference at the game level is weaker than the (forcing) 3 level preference.  This forcing preference can be made on 3 card support because opener has not denied a 5 card holding in his first bid suit.
-  * A single raise of opener's long suit is invitation at the three level, forcing to game at the four level. examples:

-|1\h|2\d||
-|3\c|4\c|game force|
-|-----------------------------------------------------|||
-|1\H|2\c||
-|2\d|3\d\invitational|
-||4\d\forcing|
-  * A simple rebid of respondr's suit is not forcing
-  * A rebid of 2N is limit
-  * A leap to 4 minor is a slam try (it it is a rebid of responder's suit, it is always used artificially, not to show a good suit - use an immediate jump shift for that purpose).  It shows one of the following:
-    * Agrees that minor if it is one of //opener's// suits
-    * Otherwise agrees one of opener's majors:
-      * If opener has bid and rebid the same major, the leap to 4\c and 4\d both agree opener's major.  4\c shows a \c control and 4\d shows a \d controls lacking a \c control (remember that control means A, K, singleton or void).
-      * If opener has bid one major and then the other, the leap to 4\c agrees \hs and the leap to 4\d agrees \ss regardless of the order bid by opener.

-====1 Spade 2 Hearts====
-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)|
-====1 Diamond - 2 Diamonds====
-**After 1\d - 2\d**
-The raise shows about 8 to 10 supporting points; this call does invite a rebid of a major (which is forcing one round).
-====After one-over-one response====
-**After 1\d - 1\s or 1\d - 1\h or 1\h - 1\s**
-Responder has shown 8+ HCP with a 5+ card suit.  The call is forcing.  Responder promises to bid again unless opener makes a simple rebid of his own suit.
-Opener's rebids:
-  * A raise of responder's long suit to the 2 level shows 3 card support and is forcing to the 3-level in that suit.
-  * A jump raise (to the 3-level) shows 5+ card support and is forcing
-  * 3N shows 5+ card support with 5-6 losers.  This is usually a shapely strong hand.
-  * A jump raise (to the 4-level) shows 5 card support and a minimum
-  * A new suit is normal canapé and denies 3 card (or more) support
-  * 1\d - 1\s/1\h - 1N show a secondary \c suit (i.e. a shorter \c suit than the \ds)
-  * 1\h - 1\s - 1N shows a 5\h332 or 6 bad \h322 minimum hand (without 3\s).  New suits by responder at the 2 level are not forcing
-  * 2N - shows a one suited hand (semi-balanced) without 3 card support (15 - 16 HCP)

-If opener does not show 3+ card support of responder's suit, then responder's jumps to the 4 level in minors follow the same rules as after forcing 2 over 1.
