Rainbow Lesson #2: Responding to Opening Bids
Preamble
______
Opening bids come in 3 types: NT openings, 2 , and
1-of-a-suit. In the case of 2 openings, Responder
generally assumes a rather passive role, leaving the
final decision up to Opener until such time as Opener
passes the baton to Responder by signing off in 2NT or
by rebidding an unsupported suit. In all other cases,
Responder assumes the role of captain until such time
as Responder relinquishes it to Opener.
______
The over-riding concern focuses on whether or not
the hands have enough strength to warrant game. If the
answer is "no", the Captain will sign off as soon as
possible. If "yes", the Captain will likely retain that
role until game is reached, and investigate the possibility
of slam in the meantime. If the answer is "maybe", the Captain
will usually endeavour to make a clearly invitational move
and then pass the final decision on to Partner. The first
question, then is always: "Are my values, added to the most
that Partner can have, enough to make game?"
Responding to a 1NT Opening Bid
______
The responses to the 15-17 point 1NT are about as
scientific as SAYC gets. Here are the responses for a
balanced or semi-balanced responding hand:
- 5NT - Quantitative, 20-21 points, forcing 6NT, inviting 7NT.
- 4NT - Quantitative, 16-17 points, inviting 6NT.
- 3NT - To play. 11-15 points. No interest in slam.
- 2NT - Inviting 3NT. 9-10 points.
- Pass - 0-8 points, no 5+card major or 6+card minor.
______
Hands are categorized as either balanced or
unbalanced. Balanced or "flat" hands come in one of
three distribution types:
______
Responses with an unbalanced hand are:
| Call |
Meaning |
4 |
A direct 4 is Responder's only chance to
use 4 as Gerber. If you are using Gerber twice
in the same year, you are either using it unwisely
or playing too much bridge! |
3 or 3 |
6+card suit, 11+ points, Game Forcing. "3-card support?" |
3 or 3 |
6+card suit, 9-10 points, invitational. |
2 |
Transfer to a long minor. In most versions of Standard American Opener rebids 2NT with
better Diamonds, 3 with superior Clubs
or equal length and strength in the minors. Responder
can stop in 3-of-a-minor or rebid 3 or higher to
look for a slam in an unspecified minor. Note:
SAYC does not give Responder the option of bidding 2NT here to show better
Diamonds. In SAYC, Opener must rebid 3 after 1NT:2 . |
2 |
5+ Spades, any point range. Once Opener rebids 2
Responder can Pass (0-8 pts.), rebid 2NT or 3
(6 Spades) with 9-11, or force game with any
other rebid. 1NT:2 :2 :4NT is Blackwood.
|
2 |
5+ Hearts, any point range, similar to 1NT:2 (above).
Note:
Unlike other versions of Standard American (which play that 1NT:2 :2 :2 is a one round force
with 5-5 or better in the majors), SAYC plays a 2 rebid as natural (4-5 in the majors) and non-forcing. |
2 |
Stayman. Either 9+ points OR 0-8 with a 3-suiter,
short in Clubs ("Psychic Stayman", when Responder
will Pass Opener's response to 1NT:2 ). Any minor
suit rebid by Responder will be game-forcing. A
major suit rebid of 2 or 2 over 1NT:2 :2 is
NOT forcing. 1NT:2 :2 :2 , though, is forcing.
Any 4NT rebid by Stayman Responder is Blackwood.

Questions
Question #1a: How do we use Gerber after responding 2C, 2D
or 2H to 1NT?
Question #1b: How do we make a
quantitative 4NT raise after responding 2C, 2D
or 2H to 1NT, then?
Question #2: What can I do with a slammish major 1-suiter?
