|1N 2||is "non-forcing" Stayman, meaning that the bidding can stop in two of a suit.|
|2 ..||denies a 4-card major|
|2 ..||shows 4 Hearts, but may also have 4 Spades|
|2 3||Bidding 3 (3 of a minor) over 2 (2 of a Major) shows 5+ of the minor bid, a 4-card major, and slam interest.
Although opener should treat this bid as if it shows slam interest, opener should not just jump to slam. Simply cue bidding an ace on the 3 or even 4 level can show slam co-interest without getting too high.
It is possible that responder has no slam interest, but is simply giving opener more information for deciding whether to play 3N or 4 of responder's major. See Kit Woolsey's book, Matchpoints, page 80.
1N-2 is a transfer to hearts (the "target suit")
1N-2 is a transfer to spades ("target suit").
Opener accepts the transfer by bidding 2 of the target suit.
After the transfer is accepted, responder has the following options:
Opener can Super Accept to show maximum HCPs (e.g.: 17 if 1N shows 15-17) and four-card support by jumping to 3 of the target suit, after which, responder has enough information to place the contract or explore for slam.
Minor Suit Transfer:
1N-2 transfers to 3. The transfer is made with a bust hand.
Responder can then pass or correct to 3.
Other Responses To 1N:
Ace Asking King Asking 1NT -- 4 1NT -- 4 4 = 0 or 4 aces 4x -- 5 4 = 1 ace 5 = 0 or 4 kings 4 = 2 aces 5 = 1 king 4NT = 3 aces 5 = 2 kings 5NT = 3 kingsIf the player using Gerber makes any bid other than 5, that is to play (including 4NT).
Interference After 1N Opening:
If the opponents overcall, Stayman and transfers are off.
Bids are natural except for a cue bid, which is game-forcing Stayman.
If the opponents intervene over a conventional response, rebids by opener show true fits.
For example, after 1N-(P)-2-(2), 3 (the suit to which responder wanted to transfer) shows 3+ Hearts. With just 2 Hearts, opener would pass or possibly bid 2N.
Rebids By Opener:
With 13-15 points:
With 16-18 points:
With 19+ points:
Responding to Jacoby 2N
Game invitational rebids after opener rebids a suit:
Game forcing rebids after opener rebids 1N:
A 2-over-1 bid promises a rebid by responder, but it is not game forcing in SAYC, so the game-invitational type bids listed above still apply. For example: after 1-2, 2-3/2N/3/3 are all invitational which opener may pass.
Game force after making a 2-over-1 bid:
Responses and later bidding follow the same principles as responding to a 1 or 1 opening.
A 1-over-1 bid is "up the line" when no 5-card suit is available. So with 4 of each major, bid Hearts first, with a 4-card major and 4 Diamonds, bid Diamonds first.
If 5-5, bid the higher ranked suit first; otherwise, bid the longer suit first; e.g.: with 5 Hearts and 6 Diamonds, bid Diamonds first in response to an opening bid of 1C.
A jump-raise of opener's minor denies any other 4+ card suit and is game invitational. There is no game-forcing raise of a minor in SAYC.
Notrump responses are natural:
Rebids By Opener
Raise is a sign-off. Could be preemptive.
3N is to play.
New suit is forcing 1 round, shows 5+ suit.
5N - A jump to 5N is a Grand Slam Force.
Doubles are for takeout through 4, penalty at 4 up.
1N overcall shows 15-18 HCPs, balanced, stopper in opener's suit.
2N (jump) (the Unusual Notrump) shows 5-5 or more in lower 2 unbid suits.
Jump overcalls are preemptive except over a preemptive opening. (You never preempt a preempt.) They follow the rules for opening Weak Twos and 3- or 4-level preempts.
A cue bid overcall when the opponents have bid two suits is natural. For example: (1)-P-(1)-2 and (1)-P-(1)-2 are both natural.
A cue bid overcall when the opponents have bid only one suit is Michaels. Responder can bid 2N in response to a major suit cue bid to ask for partner's minor. Example: (1)-2-(P)-2N, (P)-3.
Balancing bids in the pass-out seat after LHO has opened can be lighter than normal. A balancing 1N can be made with 10-15 HCPs. With more points and a balanced hand, double first then rebid notrump.

SOS in pass-out
|Cue bid||-||-||Game-force (13+)|
|Jump Raise||Limit Raise||Weak, Preempt||Limit Raise|
|Jump Shift||Strong (17+)||Weak, Preempt||Strong|
Notice above that bids like 2-Over-1, 2N, Jump Raise, and Jump Shift are similar (strong) for Uncontested and Over Overcall, but are weak Over T-O Double. That is because after partner has opened and RHO doubled, there are usually not enough points left in the deck for responder to be able to make strong bids.
Also note that 2-Over-1 mentioned in this document is not the same as 2-Over-1 Forcing. The one here is not forcing to game while the "Forcing" one, uh, is. However, 2-Over-1 Forcing is "off" in competition and bids revert to regular SAYC (or whatever adjustments or additions you've made to SAYC).
