RESPONSES BY A PASSED HAND
A two-over-one response should seldom be made in a four-card suit,
since opener may pass with a doubleton and no good rebid. A 2C or
2D response should be avoided when the hand is suitable for notrump
play.
A one-over-one response in a major can also be passed, but opener
usually bids again if he is short in that suit. Nevertheless, a
major suit response is undesirable with a weak four-card suit.
A 1D response to 1C is forcing. The force is often handy when
holding a weak major suit. Respond 1D to 1C with S-J963 H-96
D-AQJ10 C-K103. If 1D were not forcing, you would have to make a
bad bid like 1S or 2NT.
Two-For-One conventional responses to a minor are also handy (see
chapter TWO-FOUR-ONE in the book "Marvin's Conventions and
Treatments."
Temporizing bids (bid in a new suit, holding support for opener)
over a major opening are dangerous, since partner may pass. It is
usually better to raise immediately. This policy will lead to some
pretty strong single raises when responder has only three-card
support, especially in a match point game.
Jump raises are the same as by an unpassed hand, except that major
suit jumps do not always include four trumps. With three-card
support a singleton or void is desirable.
The jump raise to game tends to be stronger than the normal
preemptive game raise. Both opponents have passed, so preemption
is generally unnecessary.
A 2NT response shows 11-12 HCP, or a bad 13. Do not stretch for
this bid, which often goes down one. The Stoplight convention
(chapter STOPLIGHT in the bookd "Marvin's Conventions and Treat-
ments), applies to this response. If not playing Stoplight,
opener's rebid of his suit is a sign-off, but a new suit is
forcing.
There is no such thing as a 3NT response to a major. A 3NT response
to a minor is natural. Partner opens 1D and you bid 3NT (maybe once
in your life) with S-K2 H-A3 D-K106542 C-J108.
"Negative free bids" and associated negative doubles are handled
somewhat differently when responder is a passed hand. See chapter
NEGATIVE DOUBLES OF SIMPLE OVERCALLS in the book "Conventional
Doubles."
Cue bid responses are discussed in chapter CUE BIDS BY RESPONDER
in the book "Cue Bids."
Jump Takeout Responses
All jump takeout responses (splinter bids excepted) are preemptive
when RHO has overcalled, and jump takeouts over a takeout double
have different requirements (chapter BIDDING OVER A DOUBLE), so the
following applies only when RHO has passed.
Jump Takeout of a Minor Suit Opening
If not playing the Two-Four-One convention, a jump takeout response
to a minor opening merely shows a maximum original pass. Probably
the hand was unsuitable for a weak two bid (e.g., a seven card
suit, or suit quality not up to snuff).
Jump Takeout of a Major Opening
A jump takeout of a major opening is forcing, implying four cards
(maybe a strong three) in opener's suit, and showing a side suit
where a fit might be useful. The jump is forcing for one round
only. Responder is quite likely to pass a simple rebid of the
"agreed" suit, which is a weak sign-off. Opener must therefore bid
something else if she thinks game is likely, either because of good
overall strength or a good fit with responder's suit.
Suppose you have S-KJ54 H-63 D-AQ763 C-95. After you pass in first
or second seat, partner opens 1S. You bid 3D, forcing, showing good
spades and a diamond suit. If partner can only bid 3S, you pass.
If she has S-AQ92 H-A8 D-K105 C-10742 she will bid 4S, because of
the diamond fit. With S-AQ1098 H-KQ7 D-952 C-Q3 she signs off in
3S, knowing the hands don't fit well. With S-A1092 H-AK D-985
C-K763 she bids 4S despite the poor diamond fit, because of the
extra strength.
Opener will sometimes have a chance to make a trial bid of his own,
either to investigate game chances or to find out if slam might be
in the cards:
Opener Responder (a passed hand)
S-1074 S-9
H-AJ873 H-Q952
D-KJ3 D-A74
C-Q5 C-KJ842
Opener Responder
-- Pass
1H 3C
3D 4H
Opener's 3D call is a trial bid that hits responder well. With
diamonds and spades reversed, responder would sign off in 3H.
Responder can make a jump takeout even when he wants to bid game
for sure. Suppose you have S-K10942 H-6 D-AQ432 C-J9 opposite a
fourth seat 1S opening. You respond 3D (better than a 4H splinter
bid), intending to bid 4S if partner rebids 3S. If he jumps to 4S
by himself you make another move, probably a 5H cue bid. Then
opener can bid 6S with S-AJ765 H-852 D-KJ6 C-A4.
Suppose you open 1H in third seat with S-A42 H-KJ876 D-AK4 C-K5 and
partner responds 3C. Since you could have tried for slam opposite
a mere jump raise to 3H, you certainly have too much to bid 4H. You
should bid 3D, which partner will think is just a trial bid. If she
bids 4H over 3D, you can bid 6H with confidence. If she signs off
in 3H, you continue with 4C (or 3S, followed by 5C). If the king
of clubs were the queen, you would just jump to 4H over 3C and
leave any further move to partner.
Since a new suit bid by opener is forcing, his jump rebid in a new
suit is a splinter bid (1S-3C-4H)
