BIDDING SUMMARY
Here are the main features of the four-card major system:
Four-card majors may be opened provided there is a convenient
call on the next round. Suit quality is emphasized. Light
openings are avoided in first or second seat if the suit to
be opened is weak. Opening a three-card minor is a last
resort, when no other call is acceptable.
Opening first or second seat with a hand shape of 4-3-3-3 or
4-4-3-2 generally requires three defensive tricks, which means
passing most 12 HCP hands and some 13 HCP hands. A 1NT rebid
therefore implies 13-15 HCP, leading to a 16-18 HCP 1NT
opening, 19-20 HCP for a jump rebid of 2NT, and 21-22 HCP for
an opening bid of 2NT.
Up-the-line responding or rebidding is neither required
nor encouraged, so very weak suits are often bypassed
(especially with 4-3-3-3 hands, if a notrump bid is in
order). Raise of a minor suit does not deny a four-card
major. The raise is preferable with a weak hand and a
weak major.
Major suit opening bids or responses may be raised with
three cards, preferably J10x or better. We do play 4-3
fits occasionally, but we avoid bidding suits weaker than
Q10xx, so it's okay.
Two-over-one responses do not promise another bid, so a
1NT response shows 6-9 HCP, is not forcing, and may
bypass a very weak major (as may a 1NT rebid by opener)
with a balanced hand.
Checkback Stayman is used by both opener (opposite a 1NT
response) and responder (opposite a 1NT rebid). The
system is unplayable without Checkback Stayman.
Opener implies extra values when he raises a two-over-
one minor suit response or rebids 2NT after any two-over-
one response. Four cards or two of the top three honors
in responder's suit constitute "extra values" for a minor
suit raise. Raising a 2H response to a 1S opening does
not require extra values. A raise of any two-over-one bid
definitely shows extra values if responder is a passed
hand, since opener can pass with minimum values.
A jump preference at the three level is considered a
raise, so it's not forcing, even after a two-over-one
response. (A preference is not a raise.):
South West North East
1S Pass 2C Pass
2H Pass 2S/Pass - preference
3H/3S - raise, not forcing
Reverses by opener are not forcing on a one-over-one
responder unless he has bid a five-card suit, and do
not promise another bid if responder's next bid is of a
minimum nature. Use the jump reverse as an absolute
force (to game). Reverses are forcing on a two-over-one
bidder, but do not promise another bid.
A "high reverse" after a two-over-one response (e.g.,
1S-2H-3C) does promise another bid, even if responder
just rebids her suit or makes a simple preference.
Reverses by responder are forcing for one round only.
One notrump response to all suit openings 6-9 HCP. May
bypass a fair diamond suit or any weak four-card major,
especially with a 4-3-3-3 hand.
Two notrump response to any suit opening is forcing to
game (13-15 HCP).
