DEFENSIVE BIDDING BY A PASSED HAND
In the Direct Position
Single jump overcalls in a suit are preemptive. See PREEMPTIVE JUMP
OVERCALLS.
A 1NT or 2NT overcall shows the lower two unbid suits, at least
5-5, and may be worthless defensively. Partner prefers the lower
ranking of the two suits when holding equal length if both are of
the same rank, but will prefer a major to a minor with the same
length in each. See UNUSUAL NOTRUMP.
A direct cue bid overcall is a Michaels Cue Bid: cue bid of a minor
shows both majors, cue bid of a major shows the other major plus
an unknown minor (partner bids notrump to inquire).
When the Opponents Have Bid Two Suits
There are three ways of showing length in the unbid suits when the
opponents have bid two suits:
1) A takeout double shows length in the unbid suits, and also shows
defensive strength. The doubler should have close to an opening
bid, and some of the high cards may be in the opposing suits.
Length in a single unbid major is likely to be four cards, in both
majors 5-5 or 5-4 (not 4-5, because partner will prefer the higher
ranking with equal length).
2) A cue bid also shows a good hand, but implies that all high
cards lie in the two unbid suits:
South West North East
Pass Pass Pass 1C
Pass 1D 2D - S-AJ986 H-K10973 D-3 C-65
Dbl - S-J10987 H-QJ976 D-KJ C-A
2C - natural
3) A notrump bid is the weakest in strength, but promises at least
5-5 in the unbid suits. Partner will prefer the lower ranking with
equal length, so one might bid notrump with 5-6 in the two suits
but just overcall with 6-5.
Reopening Calls
Reopening calls when a one level opening is passed around are all
unchanged in meaning when made by a passed hand, except for the
limitation on strength implied by the initial pass. A reopening
cue bid shows a 5-4-4-0 hand, void in the opposing suit, or a two-
suited hand of any strength.
South West North East
Pass 1S Pass Pass
1NT - 10-12 HCP notrump hand
2NT - S- 3 H- 4 D-AQJ32 C-Q108765
3C - S-32 H-76 D-AJ C-KJ98752
2S - S- void H-Q876 D-Q9876 C-AQ76
2S - S-6 H-Q10873 D-AJ9632 C-5
Note that a reopening 1NT bid is not Unusual Notrump, but 2NT is.
To double and then bid 1NT requires no more than a 1NT bid (for an
unpassed hand, doubling and bidding notrump after a minimum
response shows more than a notrump overcall).
When the cue bidder takes out a suit response into a new suit, he
shows a two-suited hand and asks for a choice:
South West North East
Pass 1C Pass Pass
2C Pass 2H Pass
2S - spades and diamonds
