Development after forcing 2 over 1

is discussed 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
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

- 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
canapé - A one suited hand
The 2N rebid by opener (at his second bid) shows either a 15-16 HCP one suiter or a
canapé with extra values(if the response was 2
, then the
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
or 3 of opener's major. The 3
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
canapé.
After the bid of 3 of opener's major by responder, 3N shows the Club Canapé (as would a bid of 4
).
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:

* 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
and 4
both agree opener's major. 4
shows a
control and 4
shows a
controls lacking a
control (remember that control means A, K, singleton or void). - If opener has bid one major and then the other, the leap to 4
agrees
s and the leap to 4
agrees
s regardless of the order bid by opener.

The 2
response to 1
is constructive, but non-forcing.
The auction develops as follows:
2![]() | not encouraging |
3 /3![]() | is natural (in the canapé sense) and forcing |
3![]() | is encouraging |
3![]() | is very encouraging, but denies 3 s |
| 2N | is a contract correcting call “forcing” a 3 rebid by responder |
| 3N | is a strong hand with a canapé |
After 1
- 2
- 2N - 3
3![]() | is final |
3![]() | is a maximum hand with 2 s |
3![]() | 6 and 3 s, maximum hand (forcing) |
| 3N | Maximum hand with 3 s (not forcing, but seems unlikely that responder will pass) |

The raise shows about 8 to 10 supporting points; this call does invite a rebid of a major (which is forcing one round).

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

- 1N show a secondary
suit (i.e. a shorter
suit than the
s) - 1

- 1N shows a 5

322 minimum hand (without 3
). 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.
