Responder will now know if opener has a mini, midi or maxi
- based on the rebid.
When opener's rebid has been ambiguous, showing one of two possibilities, responder assumes the weaker option - opener may be able to bid further if necessary. Responder is master of the auction.
Responder's job as master of the auction is to work out the combined strength and decide the final level and strain.
¨ When the final contract is definite, responder makes a terminal bid which opener passes.
¨ When game might or might not be there, depending on opener's strength within the range shown by the rebid, responder makes an invitational bid.
¨ Sometimes there will be game going strength between the two hands but the best choice of final strain is unclear. In such cases the responder makes a forcing rebid below game.
How responder takes charge when a shift by opener shows a mini/midi
¨ With 6‑10 game is not responder's aim
(1) Responder passes if happy(ish) with opener's last bid
e.g. After 1©:1ª, 2¨pass with
ªAJxxx ©x ¨Qxx §Jxxx
(2) Responder bids 1NT with a cover (ideally) in the unbid suit
e.g. After 1§:1©, 1ª
bid 1NT with ªJxx ©KQxx ¨QJx §xxx
(3) Responder returns to opener's first suit with as many or more cards in it than in the second suit (i.e. responder 'gives preference'), settling for a reasonable seven-card fit
e.g. After 1©:1ª, 2¨bid 2© with
ªAJxxx ©Jx ¨Qxx §xxx
(4) Responder repeats a 6-card suit, or good 5 only if desperate
e.g. After 1©:1ª, 2¨bid 2ª with
ªKQTxx ©x ¨Qx §JTxxx
but pass with ªKQTxx ©x ¨Qxx §JTxx
¨ With 11‑12TP opposite a mini, responder has invitational values & makes one more try for game
(1) Responder raises one of opener's suits to the three-level with a fit
e.g. After 1¨:1©, 1ª bid 3¨ with
ªx ©Axxxx ¨AJxx §xxx
and bid 3ª with ªQJxx ©KQJx ¨Jxx §xx
(2) Responder rebids a 6-card suit at the three-level
e.g. After 1¨-1©-1ª or 1¨-1©-2§,
bid 3© with ªQx ©AQTxxx ¨xx §Kxx
(3) Responder bids 2NT with 11‑12HCP & stoppers in unbid suit/s
e.g. After 1©-1ª-2§, bid 2NT with ªKJxx ©Qx ¨KQxx §xxx,
or after 1¨-1©-1ª bid 2NT with ªJxx ©AJxx ¨xxx §AJxx (both 11 HCP)
¨ With 13+TP opposite a mini, responder must get to game, either immediately or by making forcing bid(s) till game is reached
(1) Responder raises opener's major to game with a fit
e.g. After 1§:1©, 1ª bid 4ª with
ªAxxx ©KQxx ¨Axx §xx
(2) Responder bids 3NT with 13+HCP & unbid suits stopped
e.g. After 1¨:1©, 2§ bid 3NT with
ªKJx ©AQxx ¨Jx §Qxxx
(3) Responder jump shifts after 1NT in a new 4+ suit(GF)
e.g. After 1§:1©, 1NT bid 3¨with
ªx ©AQJxx ¨AKxx §Jxx
(4) Responder bids a new suit after a mini suit rebid (1RF)
e.g. After 1¨:1©, 2¨bid 3§ with
ªJx ©AQxxx ¨Qx §AJxx
(5) Responder bids the fourth suit (the only unbid suit), regardless of its length or strength, when there are enough values for at least game but no ability to take one of the above actions. Bidding the fourth suit forces partner to keep bidding until game is reached.
e.g. After 1§:1©, 1ª bid 2¨with ªJx ©AKJxx ¨Qx §Qxxx
Maybe opener will bid 2NT if she has something in diamonds, or 3© if she has 3-card © support, or 3§ with 5§s. You will then raise to game in that strain.
Note that the bid of the fourth suit is artificial (a sophisticated convention to add to your growing collection). It should be used only when you have sufficient values for game but no other clear bid that guarantees you will get to game and/or to the game with the best chance of success.
How responder takes charge when opener clearly shows a midi by reversing or jumping in a bid suit
¨ With 6‑7TP opposite a midi
Responder passes a jump raise of her suit or a jump in opener's suit, both non-forcing. But a reverse or new suit at the 3-level is forcing, in which case responder chooses an option from the next category.
¨ With 8‑9TP responder must bid again
(1) Responder simple raises opener with newly-revealed fit.
e.g. After 1¨:1ª, 2© (a reverse)
bid 3¨ with ªKJxxx © Qx ¨xxx §Qx
now knowing opener has 5 ¨s
(2) Responder bids NT with a stopper in the unbid suit.
e.g. After 1§-1ª-2¨(reverse)
bid 2NT with ªAJxxx ©QJx ¨xxx §Tx
(3) Responder repeats own very good 5/+ card suit with neither of the above
¨ With 10+TP opposite a midi, responder must get to game
(1) Responder bids game in opener's major with a fit
e.g. After 1¨:1ª, 2© bid 4© with
ªAJxxx ©Kxxx ¨x §xxx
(2) Responder bids 3NT with cover in unbid suit(s)
e.g. After 1§:1©, 3§ bid 3NT with
ªKxx ©AJxx ¨QJxx §xx
(3) Responder bids game in own good 6+card major
e.g. After 1¨:1ª, 2© bid 4ª with
ªAKJTxx ©x ¨Qx §xxxx
(4) Responder bids the fourth suit if not clear about final contract to force partner to keep bidding
e.g. After 1©:2¨, 3§ bid 3ª with
ªJxx ©Qx ¨AKxxx §Txx
